Naughty Boy's Runnin (Lose It All) featuring Guillaume Nery freediver


From Promonews

It's been ready for a while, but now that vocals by Queen Bey have sprinkled stardust on the track, one of the most spectacular videos of the year is finally out.
And Charlie Robins' jawdropping video for Naughty Boy's Runnin (Lose It All) has to be an underwater-shot music video like none before it: a love story of a couple destined to come together by the fact they appear to live (and to run) under the sea.

As with his video for Klangkarussell's Netzwerk last year, Charlie Robins' inspiration has come from studying an extraordinary exponent of an extreme pursuit.

In this case it was free-diving world champion Guillaume Nery, and his filmmaker partner and fellow free-diver Julie Gautier, and their film Ocean Gravity.
It led to a collaboration – and this video has been co-directed by Gautier with Robins - that's a majestic accompaniment to the song.
"It wasn’t an easy video to get off the ground initially, though [commissioner] James Hackett was a firm believer from the moment we pitched Charlie’s idea to him in a brief email," explains producer Sarah Tognazzi.
"Strangely enough, James had already contacted Guillaume & Julie himself when initially hearing the track. This created an enormous synergy from everyone involved to get this video made."

There was only one place that an idea which required Nery to run along the sea-bed, and co-star (and fellow free diving champion) Alice Modolo to run upside down under the surface of the water, could be achieved.
That was a small channel off the coast of Rangiroa, a tiny atoll in French Polynesia, off the coast of Tahiti.
With crystalline waters, 27 C water temperature, a shallow depth of only 15 meters, allowing the sun to light the scene naturally, and the strongest current in the world, this was also where Nery and Gautier shot Ocean Gravity.
"These natural conditions allowed for the magical underwater effects to be achieved entirely in-camera, beautifully shot on the Dragon by Jacques Ballard, who had previously collaborated with Guillaume and Julie," explains Tognazzi.
As a result this video manages that very rare thing - to look impossible and real at the same time.


But the original idea regarding the underwater illusion of walking on water surface was initiated in 2014.

From Inquisitr

A group of freedivers in the Canary Islands have utilized their expertise to film an astonishing video of underwater illusions, in which they appear to walk on water, sit cross-legged on the ocean’s surface, and fly through the void like a superhero, before they are pulled from the sea in a scene reminiscent of a sci-fi movie.
The illusions are the handiwork of brothers Armando and Francisco del Rosario, according to the Daily Mail.
Shot by biologist Armiche Ramos, the stunning footage employs no computer generated effects, relying instead on the abilities the pair have developed as freedivers.
Though several camera tricks were utilized to create the underwater illusions, they amount only to altering its orientation.

"Walking On Water" Illusion

The trio, who call themselves the Ocean Brothers, filmed their illusions as part of an underwater photography competition, World Shoot Out.
Their entry, which was filmed in El Hierro, the smallest of the Canary Islands, won the prize for best short film.
“We didn’t use any special effects, just camera tricks and weights which were hidden inside the wetsuits,” Ramos said.
“People who watch it usually don’t know what’s happening, they think that the images are made by computer.”

The illusions took three years to record, as the freedivers were forced to wait for optimal conditions, according to Barcroft TV.
At one point, filming was suspended for a year, due to an active underwater volcano in the region.
“The location is not always calm and we had to wait for the correct moment for several months at a time,” Ramos noted.
As the video begins, one of the divers can be seen running on the surface of the ocean, though in reality he is inverted underwater. In another segment, a diver sits cross-legged on the water in a similar fashion, before one of them is filmed flying through the underwater world wearing a Superman-like cape.
In the final scenes of the video, one of the divers walks along a rock face, and is pulled out of the sea in a scene reminiscent of the iconic portal from Stargate.

Earlier this year, a group of freedivers in the Atlantic filmed a far different experience while underwater.
As the Inquisitr previously reported, one of the divers was rammed by a whale shark, unaware that the animal was behind him until the last second.
The underwater illusions created by the Ocean Brothers reveal not only the astonishing beauty of the world below the surface, but also the full potential of their skill as freedivers.

An exclusive look at Nautor’s Swan most ambitious yacht yet

Find out more about the origins of Nautor's Swan
from the founder of this legendary boat building company, Pekka Koskenkyla.

From WSJ by Finn-Olav Jones

The cult Finnish yacht maker Nautor’s Swan seduces sailors with sleek and speedy designs. Come aboard its latest, most ambitious vessel, Leonardo Ferragamo’s Solleone

ABOUT SIX YEARS AGO, Paul Glimcher, a New York City neurobiologist and lifelong sea dog, was halfway across the Atlantic Ocean when a storm hit his 54-foot Nautor’s Swan sloop.
Even such an experienced sailor, who already had a round-the-world tour under his life vest, had to give this storm some consideration.
“Here we were 1,500 miles from land. The seas were running 16 to 18 feet and the wind speed was 40 knots [46 miles per hour],” remembers Dr. Glimcher.
So what did he do?
“We went below and baked bread.”

An ideal yacht exists in two worlds: the exterior one, in which the bow gracefully slices through the “restless wave” of which the Navy hymn sings, and the interior one, which is so comfortable that when the going gets tough, the tough can bake bread.
Such wind palaces are rare, and so are the owners who can afford them.
As a result, the names of certain cult yacht makers—Oyster, Perini Navi, Wally, Royal Huisman, Nautor’s Swan—are whispered with the same hushed pride that 0.1 percenters exhibit when saying “my Gulfstream” or “my Picasso.”

It’s a rarefied world, not just for the price tags, which can easily surpass $10 million, but also for the costly upkeep, which involves a half-dozen highly specialized crew members.
The gladiatorial communities that gather around each brand are as competitive about their choices as they are about the business endeavors that afforded them these boats in the first place.
Nautor’s Swan’s club includes tech billionaire and philanthropist Thomas Siebel and fashion photographer Patrick Demarchelier.
“It’s a very strong boat. Both technically and aesthetically it’s great,” says Demarchelier, whose 53-foot Swan is called Puffy.
“Its lines are beautiful. I’ve used it for several shoots.”
“You can tell a Swan just by the feel of the wheel—they’re incredibly responsive. They carve the water really well, even in a squall,” says California oil magnate Donald R. Macpherson Jr., who, as a boy, sailed a Nautor’s Swan with his father and who recently spent a year and a half overseeing the construction of Freya, his 90-foot Swan.
“I wanted to re-create the experience I had with my father with my own family,” he says.

Whereas many other yachts are, like iPhones or high-end watches, amalgamations of state-of-the-art components supplied by other companies, including the latest push-button winches and sail trimmers, almost everything you see on a Nautor’s Swan—from the deck hardware to the bilge pump system—has been customized first in 3-D graphics on the company’s computers and then by Nautor’s Swan’s own craftsmen in the remote Finnish town of Jakobstad.
“You are creating self-contained worlds with each boat,” says Heini Gustafsson, the senior designer of Nautor’s Swan, where the smallest of the seven models currently offered is 54 feet long.
“It’s a unique place—where else can you get the chance to design everything from the sheets to the cutlery?”
Teak samples from the interiors of every yacht built are stored at the boat works so that repairs and modifications can be made later.

So it’s no surprise that the boat builder’s newest owner is the chief executive of a luxury fashion and lifestyle brand.
Leonardo Ferragamo, one of the six heirs of Salvatore Ferragamo, recently built one of Nautor’s Swan’s most audacious boats yet for himself.
“I am so intrigued with it,” says Ferragamo, 62, his usually calm boardroom voice rising with excitement.
As he sits in his Milan office, his new racing yacht, the first Swan 115, Solleone, is undergoing its initial trial in the northern Finnish seas near Jakobstad.
“It’s already sailing at 15 knots [17.3 mph]—but I think it will reach 25 knots [28.8 mph],” he says of the boat. (An average sailboat usually cruises along at five or six knots.)

Jakobstad is a spotless, typically Scandinavian modernist town, built around a 17th-century core of buildings, yet it’s an outlier in Finland.
It’s located on the Gulf of Bothnia, across the gulf from Sweden, and most people here speak Swedish.
Visitors rarely hear the town called by its official Finnish name, Pietarsaari.
Locals pronounce “no” with an easy and joyous nej and “yes”—jo—with a hesitant inhale.
Blessed by tall forests of raw material and protected granite coves, this area has been a popular boat-building spot for three centuries.

“Everyone here has a boat project in their backyard,” one local woman told me.
“My father built our family’s 26-foot sailboat on our lawn.”
But the town was put firmly on the nautical charts in 1966, when paper salesman and serial entrepreneur Pekka Koskenkylä launched the yacht company that was to become Nautor’s Swan.
He had a vision of applying Finnish functionalist design to making the speedy yet comfortable boats that are today responsible for the private jets parked at the tiny local airport.

Using his formidable salesman’s skills, Koskenkylä convinced the world’s best-known naval architects, New York–based Sparkman & Stephens—which is responsible for eight America’s Cup winners—to work for his fledgling company.
Together they created yachts that could sail with the best on the regatta circuit.
In 1974, a Swan 65 won the first-ever Whitbread Round the World Race—an annual Phileas Fogg–type event, hatched by a group of thrill-seeking English tycoons and now called the Volvo Ocean Race—earning Nautor’s Swan instant prestige.

That inaugural half-year odyssey is still legendary among sailing aficionados: Despite facing epically challenging conditions that included 300-foot icebergs and 50-mile-an-hour winds, the Swan prevailed.
In 1980, Germán Frers—a one-time Sparkman & Stephens chief designer who had left to found his own eponymously named firm—took over as Nautor’s Swan design guru, a position he retains.
He had already created renowned crafts of the day including Beau Geste, Wizard of Paget, Quest of Paget and Simba, and soon he designed a new Nautor’s Swan.

Its shallow hull, vertical bow and narrow fin keel made the boats into clean and efficient sea missiles.
Now, a half-century since its founding, Nautor’s Swan has produced, hand-screw by hand-screw, some 2,000 boats, from the relatively chubby cruising yachts of the ’60s and ’70s to the more recent distinctive flush-deck, blue-banded boats.
But it hasn’t been all smooth sailing.
In 1972, after a fire in the boatyard that proved costly, Koskenkylä was forced to sell his company to the local paper mill, and by the late ’90s it was suffering losses.
In 1998 Ferragamo, the chief executive officer of Palazzo Feroni Finanziaria S.p.A, the holding company for the family’s diverse businesses, stepped in and bought a controlling interest in Nautor’s Swan.
A passionate sailor, he already owned two Swans before taking over the boat works, and he has since added another six to his stable.
“When I first got married, my wife wanted a summerhouse and I wanted a Swan—I bought the Swan first,” says Ferragamo, who visits the yard every two or three months.
“So when I acquired the company, I already had such respect for the brand. I recognized the enormous pride and craftsmanship that went into building a Swan.”

After he became chairman, “initially there might have been some suspiciousness from the Finnish side,” says Ferragamo.
“They might have thought that I was just a decorator rather than someone with a long-term plan.” Since he has arrived, more than 15 new Swan models have been introduced, such as the popular yacht Swan 45, which was unveiled in 2001 and could be built in under a year, faster than the average Swan.
Meanwhile, carbon fiber soon replaced the older fiberglass hulls.
“There were some rough patches,” agrees Marcus Jungell, the company’s sales director.
“We Finns might seem a little introverted. They bring Italian flair.”

The new 115-footer, of which Solleone is one of four thus far, has been the most ambitious project resulting from the Italian-Finnish collaboration.
A yacht of such enormous size is challenging to design to racing specifications, and each one will cost $16 to $22 million.
(But the company seems confident of its success—there are already plans for a 130-foot Swan.)
I drove to Kållby, 8 miles inland, to have a look at one of them in what must be Finland’s most unusual sauna: a long white-painted hangar where boat hulls and other carbon fiber elements are electrically baked in the vacuum of giant temperature-tolerant plastic bags.
Workmen in overalls were carefully stretching out mats of laminate on the hull before wrapping the whole thing in plastic, pumping out the air from beneath and warming the ovens to 195 degrees.
It was as if Arthur Treacher had captured Moby Dick.

This baking process is one of the first steps in a 115’s 20-month design and construction schedule. Carbon fiber is the material of choice for anything designed for speed, from Formula One cars to racing yachts, thanks to its enormous strength-to-weight ratio.
However, air is the great enemy; bubbles can create cracks and weaken the overall structure.
“The old-fashioned way of hand-basting laminate will still have 7 to 8 percent air content, even if you are good at it,” says Thomas Lill, who oversees Nautor’s Swan’s composite process.
“Baking our hulls like this can reduce the air content to 0.5 percent.”

Down at the company’s harbor facility, Solleone is tied to the harbor dock, its hull dwarfed by the 151-foot mast.
Workmen are still sanding the already-smooth teak deck.
Anders Bertlin, the yacht’s project manager, pointed at our feet.
“See this? The planks all line up straight. They don’t curve with the boat like others do.”
Indeed, the entire deck is lined like a bowling alley from stern to bow, across all hatches.
This unusual aesthetic flourish, coupled with white caulking, gives the deck a gleaming, elegantly minimalist feel—a fantastical white saucer that floats a few feet above the choppy lead-gray waters.
There’s also a practical reason for the smoothness of the deck: fewer rope snags—the bane of sailors.

For the interior, Ferragamo worked with his frequent collaborator, the Florentine architect and interior designer Michele Bonan, to add Mediterranean touches: Glossed teak paneling with customized wood shutters set off by silver picture frames; door latches and drawer pulls cushioned with stitched leather; stateroom headboards done up in red and blue percale; and the all-important galley, set in the prime spot just forward of the yacht’s center.
Perhaps most important, Solleone’s 11.5-foot keel can be raised, allowing the boat to enter the shallower waters of most harbors.
The 450-horsepower Scania diesel engine is muffled thanks to a complex system of insulation—not even the silverware vibrates when it’s fired up.

Ferragamo would doubtless like to have the same sense of stability in the current world financial markets, which are choppy waters for sales of super-yachts.
“Traditionally, our market was evenly divided between the U.S., Northern Europe and the Mediterranean,” says sales director Jungell, who adds that the current Mediterranean economic climate is pushing them to pursue emerging markets like Russia and China.
But looking at the new 115, one can’t help but suspect that this newest venture is about something more than quarterly financial statements.
There’s comfort in the fact that both Ferragamo and Nautor’s Swan hail from cultures that take very long-term views of the business of design.
“My family has a saying,” says Ferragamo.
“ ‘Heritage is the foundation for the bridge you want to build.’ You need to respect it but not just maintain it. With Nautor’s Swan, we want a stronger drive toward evolution—never a revolution.”

After 60 million years of extreme living, seabirds are crashing

Britain's seabirds are in crisis. Catastrophic breeding failures have swept along our shores and have hit many of our colonies of puffin, arctic tern, guillemot..

From The Guardian by Jeremy Hance

Every day for sixty million years, seabirds have performed mind-boggling acts of derring-do: circumnavigating the globe without rest, diving more than 200 meters in treacherous seas for a bite of lunch, braving the most unpredictable weather on the planet as if it were just another Tuesday and finding their way home in waters with few, if any, landmarks.

But now seabirds, like so many other species, may have met their match.

Conservationists have long known that many seabird populations are in decline, but a recent paper in PLOS ONE finds the situation worse than anticipated.
According to the researchers, seabird abundance has dropped 69.7% in just 60 years – representing the deaths of some 230 million animals.

“I was very surprised with the result, it was considerably greater than I’d expected,” said Edd Hammill, co-author of the paper, with Utah State University.
“What we should take away from this is that something is serious amiss in the oceans.”

Ben Lascelles, a Senior Marine Officer with Birdlife, who was not involved in the study, said he found the research alarming because the decline appeared practically indiscriminate, hitting a “large number of species across a number of families.”

Seabirds, which include any bird that depends largely on the marine environment, comprise nearly 350 species worldwide – an astonishing variety of extreme-loving birds.
For example, the indefatigable wandering albatross, which sports the largest wingspan on the planet; the child-sized Emperor penguin, the only bird that breeds during the Antarctic winter; and the tiny storm petrel that practically capers on the water as it feeds – they are named for St. Peter after all.

But, given that seabirds inhabit both the open ocean and the shoreline, this eclectic mix of birds faces a litany of threats: overfishing, drowning in fishing lines or nets, plastic pollution, invasive species like rats in nesting areas, oil and gas development and toxic pollution moving up the food chain.
And as if these weren’t enough, the double-whammy of climate change and ocean acidification threatens to flood nesting sites and disrupt food sources.

“Seabirds are particularly good indicators of the health of marine ecosystems,” explained lead author, Michelle Paleczny with the University of British Columbia and the Sea Around Us Project.
“When we see this magnitude of seabird decline, we can see there is something wrong with marine ecosystems. It gives us an idea of the overall impact we’re having.”

Bu with such a large number of species across such a wide variety of environment one is left asking: how did the scientists count so many birds?

Counting Birds

First, the team of researchers scoured all the population data on seabirds available.
They found demographic data on 3,213 populations.
But they couldn’t use all of theses counts, since conservationists had surveyed many of these far-flung populations just once or twice – not enough to show a real trend

The team eventually selected 513 populations that had been counted at least five times.
In all, these populations represented about 19 percent of the world’s seabirds.

Still, Hammil said he believes the team’s findings “are an accurate representation of what is happening worldwide.”
He added, “although we did not include every population, all seabird families were included, and we included populations from every major coastline in the world.”

Paleczny also said that when the researchers looked at the differences between monitored and unmonitored populations, they saw “no evidence that the monitored populations are declining more.”
The findings are also bolstered by past research. In 2012 a paper in Bird Conservation International found that 28 percent of seabird species are threatened with extinction with 47 percent in decline.
This meant, in all, seabirds were about twice as likely as land-based birds to be threatened with extinction.
“The trends for many seabird species have clearly been downwards for a number of years, and this paper provides further evidence of this,” Lascelles said.

Still, Paleczny and Hammil’s research arguably paints an even more alarming picture of the state of the world’s seabirds.
For example, according to them, the tern family has fallen by 85%, frigatebirds by 81%, petrels and shearwaters by 79%, and albatrosses by 69%.

Such dismal findings point to one of the study’s patterns: open ocean birds – such as albatrosses, frigatebirds, petrels and shearwaters – are generally faring worse than birds that stick near the coasts.

“[Open-ocean] seabirds are hit especially hard due to their large geographic ranges. Because these species travel so far, there is a greater chance they will encounter threats,” said Hammill who noted that coastal birds “in some cases” are doing better because of improved management of breeding areas and improved fishing gear.

But even when threats were minimized, Lacalles noted that recovery requires diligence and patience.

“Most seabirds are long-lived and slow reproducing, this means even quite small increases in mortality can lead to significant population declines, which they take a long time to recover from.”

And even some widely-dispersed coastal birds are undergoing heavy declines.
For example, the study found that cormorant and shag populations have fallen by 73%.

Going forward

Given all the threats facing the world’s seabirds, it’s fair to ask: where do we start when it comes to conservation?

“We already have solutions to many of the threats...it’s just they need scaling up and implementing across industries and geographies,” Lascelles said.
“Increased efforts should be made to rid seabird colonies of invasive species, reduce bycatch in fisheries or the ensnaring of birds in fish nets, and setting up conservation areas.”

Paleczny also called for the creation of international marine protected areas to cover the wide ranges of seabirds.

But other penguin species aren’t faring so well.

Protected areas in the oceans lag far behind those on land.
Currently, only 2% of the world’s oceans are under some form of protection and less than half of those ban fishing altogether.
In contrast, nearly 15% of the world’s terrestrial landscape is protected.

With so little of the ocean theoretically closed to fisheries – less than 1% – it’s hardly shocking that many seabirds are suffering from overfishing.
Indeed, an illuminating study from 2012 found that whenever fish abundance dropped below one-third of maximum levels, seabird populations began to fall in response.

“What this is saying is that [seabirds] have evolved to exploit average to above-average feeding conditions,” co-author Ian Boyd told Mongabay in 2012.
“This isn’t really very surprising, but some things don’t become obvious until the evidence is right in front of you.”

The accidental bycatch of huge numbers of seabirds in a variety of fisheries (e.g. longline, trawl, gillnets) is one of the main threat facing seabirds and has driven the declines in many species, particularly albatross.
However a number of simple mitigation measures are available, and where they have been implemented the reduction in bycatch has been dramatic.

At the time, Boyd said their findings should result in a new campaign to save “one third for the birds” (and other marine predators) from the world’s fisheries.

But to Hammill the “most pressing issue” is plastic pollution.

Long neglected by environmentalists – perhaps due to the intractability of the problem – the issue of plastic pollution in the oceans has been slowly getting more notice.
A paper released last month found that 90% of the world’s seabirds likely have plastic in their stomachs.

“I have seen everything from cigarette lighters...to bottle caps to model cars. I’ve found toys [inside seabird guts],” co-author Denise Hardesty, with CSIRO, told the Associated Press.

Seabirds continually mistake plastic for fish eggs, devouring large amounts.
Plastic in animals’ stomachs not only release deadly toxins, but can also lead to slow starvation by obstructing the animals’ bowels.
Birds even feed plastic bits to their young, killing their fledglings en masse.

In the end, large-scale actions to help seabirds could also go a long way in cleaning-up our increasingly trashed marine ecosystems.

“The oceans are still woefully under protected and fisheries need greater management and enforcement. All of these activities need investment and support of governments around the world to make them happen,” Lacalles said.
“These actions will build resilience in the seabird populations in the short term, which they need in the face of emerging threats such as climate change.”

Equinox sun rises due east, sets due west



From EarthSky by Bruce McClure

The September 2015 equinox happens on September 23 at 8:21 Universal Time, which translates to 3:21 a.m. Central Daylight Time for us in the central U.S.
So as you read this, the exact moment of the equinox may have already happened for you.
It’s often said that – at each equinox – the sun rises due east and sets due west.
And that’s true.
But why?
How can you conceptualize this?



First you need to know this.
An equinox occurs when the sun crosses the celestial equator.
No matter where you are on Earth, the celestial equator intersects your horizon at due east and due west. See the diagram below to try to visualize that.
At its highest point in your sky, the celestial equator appears high or low, depending on your latitude.
The imaginary celestial equator is a great circle dividing the imaginary celestial sphere into its northern and southern hemispheres, so, from the equator, it’s directly overhead, for example, wrapping the sky directly above Earth’s equator.
For purposes of today’s visualization, though, the height of the celestial equator in your sky doesn’t matter.
What matters are these two things.
One, the sun is on the celestial equator at the equinox.
Two, the celestial equator intersects your horizon at points due east and due west. Voila.
The sun rises due east and sets due west on the day of the equinox, as seen from around the globe.

Where does the celestial equator intersect your horizon? 
The imaginary celestial sphere surrounds Earth.
Seen from Earth’s equator, the celestial equator is overhead.
Seen from Earth’s poles, the celestial poles are overhead.
But from northern mid-latitudes, for example, the north celestial pole appears at a height in your northern sky that depends on your latitude.
Likewise, the path of the celestial equator across your southern sky depends on your latitude.
Meanwhile, no matter where you are on the globe (unless you are at a pole), the celestial equator meets your horizon at points due east and due west.
Due east and due west are like the “pivot points” from which the celestial equator appears to shift to various heights in your sky, depending on your latitude.

Why does the sun rises due east and set due west at the equinoxes? 
The blue line is the celestial equator (always at your due east and due west points).
The purple line is the ecliptic, or sun’s path.
At the equinox, these two lines intersect.
The sun is on the celestial equator.
So the sun rises due east and sets due west, as seen from all points on the globe (except the poles). Illustration via JCCC Astronomy.

This fact – the sun rising and setting due east and west at every equinox – makes the day of an equinox a good day for finding due east and due west from your yard or other favorite site for watching the sky.
Just go outside around sunset or sunrise and notice the location of the sun on the horizon with respect to familiar landmarks.
If you do this, you’ll be able to use those landmarks to find those cardinal directions in the weeks and months ahead, long after Earth has moved on in its orbit around the sun, carrying the sunrise and sunset points southward or northward.

The north face of an equatorial sundial receives sunshine in spring and summer, and the south face receives it in autumn and winter.
On the equinoxes, sunshine should hit neither side of the sundial, but only the edge.

Now let’s think about what an equinox really is.
It’s an event that happens on the imaginary dome of Earth’s sky, but each equinox also represents a real point on Earth’s orbit.
What happens at every equinox is very real – as real as the sun’s passage across the sky each day and as real as the change of the seasons.
Our ancestors couldn’t have understood the equinoxes as we do.
They didn’t understand them as events that occur in the course of Earth’s yearly orbit around the sun.
But if they were observant – and some were very observant indeed – they surely marked today as being midway between the sun’s lowest path across the sky in winter and highest path across the sky in summer.
And that’s where we are, in orbit, at this equinox.
We’re midway between the two extremes of the sun’s path in your sky.

 The seasons result from the Earth's rotational axis tilting 23.5 degrees out of perpendicular to the ecliptic - or Earth's orbital plane.

An equatorial ring was used in ancient times in an attempt to determine the equinoxes.
The ring plane is set parallel to the plane of the Earth’s equator.
If the equinox happened during the daylight hours, the inside of the ring was expected to be completely in shade at the equinox.
Image via Wikipedia

Bottom line: The 2015 September equinox comes on September 23 at 8:21 Universal Time – or 3:21 a.m. Central Daylight Time for us in the central U.S.
At each equinox, the sun rises due east and sets due west.
The diagrams and explanations in this post are meant to help you visualize that.

Do humans have a future in deep sea exploration?

From NYTimes by Chris Dixon

Entering the Hawaii Undersea Research Laboratory hangar is akin to stepping onto the set of a Spielberg film.
The dull metal shell, perched on the Makai pier along the Windward Coast of Oahu, is nondescript, but the inside bristles with Zodiac boats and a dizzying assortment of hoists and tools, and the walls are festooned with 30 years of snapshots.
At the center of it all, two 20-foot-long Pisces submarines sit atop skids like alien spacecraft, their robotic arms outstretched, beckoning for another mission.

The laboratory, part of the University of Hawaii and better known as HURL, has been the sole submersible-based United States deep-sea research outpost in the mid-Pacific since the 1980s.
At its helm is Terry Kerby, perhaps the most experienced submersible pilot alive.
With a crew of five, Mr. Kerby and the Pisces subs have discovered more than 140 wrecks and artifacts, recovered tens of millions of dollars in lost scientific equipment, and surveyed atolls and seamounts whose hydrothermal vents and volcanoes were unknown.

“It’s very unusual to have a facility that large and well-equipped in the middle of a large ocean basin,” said Robert Dunbar, a Stanford oceanographer.
“They’ve done a remarkable thing over there, largely due to Terry’s expertise.”
But today, Mr. Kerby faces the possible mothballing of his fleet.
The forces at play are the same as in many other realms of science — dwindling budgets, of course.
And robots.
Robotic subs can stay down for days and reach extraordinary depths, instantly relaying their finds to scientists and an Internet-connected global audience.
But they cannot go everywhere, and many scientists argue that studying the deep without direct human observation yields at best an incomplete understanding.
“You can’t replace a Terry Kerby with a robot,” said Andy Bowen, principal engineer at Woods Hole. “It’s not possible.”
At 65, Mr. Kerby is tanned and fit, thanks to daily two-mile ocean swims.
He has been piloting submersibles at Makai for better than three decades, starting in the mid-1970s harvesting corals.
He shifted to the University of Hawaii and the National Oceanic and Atmospheric Administration, which had bought the Makai facility to expand the nation’s deep-sea capabilities.
In 1985, Mr. Kerby found the Pisces V submersible idled in Edinburgh and persuaded the university to spend $500,000 for it.
Relatively big, it could dive to 6,500 feet.
“She cost $4 million to build in 1972,” he said. “And would cost $50 million to build today.”
Pisces V came with no instruction manual, but Mr. Kerby found it was highly maneuverable and could hover motionless, even in strong currents.
It also operated untethered from a mother ship, allowing exploration of caves and overhangs. Coupling Pisces with the University of Hawaii’s research ship, the Ka`imikai-O-Kanaloa, and a home-built submersible platform enabled Mr. Kerby to carry out missions from 60 feet down, during surface conditions too rough for any other submersible.
Mr. Kerby racked up discoveries, beginning with exploration of the Loihi seamount off Kona. Eighteen years of return missions have revealed that an area once thought dead is a vibrant world of myriad ecosystems and volcanism still shaping the Hawaiian Islands.
Along Loihi and other slopes, the team discovered living corals that predate even California’s bristlecone pines.

In part 1 of a two-episode look at the submersible operation at the Hawaii Undersea Research Lab, we meet Terry Kerby, a legend of the underwater world.
Terry has been piloting submarines for over 30 years.
He and his team recently redeployed an old technology to help them save money in times of reduced funding for scientific research. The LRT-30a is a barge that transports the sub out to its dive site.
A team of divers then takes the barge underwater with the submarine still attached and proceeds to launch the sub while it is underwater.
see part II

In 2000, Mr. Kerby acquired a sister sub, the Pisces IV, from Canada for $80,000.
Exploring in tandem made diving safer and enabled film crews to show discoveries in the context of the submersibles.
The subs have appeared in more than 20 documentaries, including National Geographic’s “Fires of Creation,” in which the oceanographer Robert Ballard, whose discoveries included the wreckage of the Titanic, descended with Mr. Kerby to the caldera of Loihi.
Besides plumbing geological and ecological mysteries, the Pisces subs have made dives that sharpened views of history.
A little more than an hour before the first bombs fell in Pearl Harbor on Dec. 7, 1941, the American destroyer U.S.S. Ward reported that it had sunk a tiny submarine near the harbor entrance.
But in a blunder that still fuels conspiracy theories, the report never reached far enough up Navy command to initiate a mobilization of defenses.
The Ward’s claim was disputed, even in the official Pearl Harbor investigation report.
The sub thus became a holy grail for marine archaeologists and historians.

Pisces V lauched from R/V KoK

In August 2002, Mr. Kerby lay across the bench of the Pisces V, 1,200 feet down, gazing at the dark, frigid world beyond his porthole.
For hours he had been sweeping the seafloor four miles south of Pearl Harbor, hunting for the mythic sub amid three dozen potential sonar targets and fighting a rising sense of futility.
“We were chasing our tails down there,” he said.
But then, looming out of the darkness, Mr. Kerby faced a torpedo shape three times as long as the Pisces. It was a 78-foot-long submarine bearing the exact damage – a four-inch hole punched just beneath its conning tower — described by the Ward’s crew.
“We’d searched for 10 years,” Mr. Kerby said.
“I just couldn’t believe it.”
After that find, NOAA directed Mr. Kerby to further document the wreck-strewn waters off south Oahu.
In another National Geographic project, the team discovered four mammoth Japanese I-series submarines captured by the Navy at the end of World War II and scuttled to keep them out of Soviet hands.

Experience the first view of a World War II-era Imperial Japanese Navy mega-submarine, the I-400, lost since 1946 when it was intentionally scuttled by U.S. forces after its capture.
It now sits in more than 2,300 feet of water off the southwest coast of O'ahu. 

“What the Pisces program has done, mostly underfunded and unappreciated, over the years is unmatched,” said Sylvia Earle, former chief science officer for NOAA.
“It’s baffling to me that more understanding and funding hasn’t been heaped upon them.”
Five years ago, piloted deep-sea exploration appeared on the verge of a boom, funded by wealthy explorer/entrepreneurs.
In 2012, after spending $10 million building his Challenger Deep submersible, the filmmaker James Cameron became one of three humans to reach the 6.8-mile depths of the Marianas Trench, the deepest ocean spot on Earth — and the only one to do it solo.
The Virgin Airlines founder Richard Branson promised a new era of exploration with his $17 million Virgin Oceanic submarine.
And Eric E. Schmidt, Google’s chairman, joined with Dr. Earle on the $40 million Deep Ocean project.
Yet all those programs have withered.
And by fiscal year 2014, the deep-sea budget for NOAA was down to $26 million.
For comparison, NASA’s exploration budget was $4 billion.
The United States Navy has abandoned piloted submersibles with the exception of Alvin, which it owns jointly with Woods Hole.
In 2013, NOAA said it would no longer fund the Pisces program, leaving the United States with no Pacific deep-sea facility.
HURL has money to last until the beginning of 2016.
After that, the university may be forced to sell the submersibles.
“There are only eight deep-diving submarines left operating in the world” that can go 6,500 feet or deeper, said John Wiltshire, director of HURL and a member of the Woods Hole submersible scientific advisory committee.
“So we’re about to lose a quarter of the world’s fleet.”
What changed?
To hear Dr. Ballard tell it, the shift began during a 1977 dive aboard Alvin off the Galápagos Islands.
About 8,000 feet down, Dr. Ballard noticed a colleague paying more attention to the camera monitor than to Alvin’s tiny windows.
“He turned his back on me to look at the screen,” Dr. Ballard said.
“I said, ‘Why?’ He said, ‘I can get closer.’ I said, ‘Then why the hell are you here?’ ”
Afterward, Dr. Ballard said he realized fundamental truths of piloted deep-sea exploration: It’s cold and scary, time in the deep is limited, and robotic vehicles might do the same work for less money.
He persuaded the Navy to fund two remote exploration vehicles, Argo and Jason, for use by Woods Hole.
On Sept. 1, 1985, Argo first filmed the wreckage of the Titanic.
Since then, remote deep-sea vehicles have proliferated in exploration, mining and drilling. Dr. Wiltshire estimates perhaps 10,000 are in operation.
NOAA’s deep-sea efforts are focused on two ships: its own Okeanos Explorer, based in Rhode Island, and the E/V Nautilus, a joint project with the Ocean Exploration Trust, founded by Dr. Ballard and based in Connecticut.
Nautilus has an autonomous underwater vehicle that follows a programmed route and two tethered remote submersibles.
Typically, Dr. Ballard’s ships carry just one or two senior oceanographers; engineers and technical staff deploy and monitor the submersibles, which, via satellite link, deliver real-time images across the world via the Internet.

Dr. Ballard described a recent Nautilus expedition that sent its submersibles two and a half miles down into the Cayman Trough.
In a piloted dive, the descent and ascent would take six hours each, leaving mere minutes for seafloor exploration.
“Now we’re going down to 20,000 feet and spending days,” he said.
“And we have the entire world participating.”
To most marine scientists, including Mr. Kerby, robots have clearly won the deep-sea war.
It’s now a question of whether lingering advantages to piloted exploration should be discarded.
Mr. Kerby described a recent robotic mission that Pisces might have done better.
In 2012, Ric Gillespie, a retired naval aviator, and Dr. Ballard announced a sonar hit off Nikumaroro Island in the South Pacific that might represent the wreckage of the Lockheed Electra flown by Amelia Earhart.
Mr. Gillespie requested Mr. Kerby for the expedition, but the Pisces subs were down for maintenance, so his team instead relied on robotic technology.
The tethered sub was unable to explore the near-vertical sea walls and could not deploy over days of rough seas.
Eventually, an untethered robotic vehicle became lodged in a reef overhang and had to be rescued by a tethered robot.
The recovery nearly required the University of Hawaii’s Ka`imikai-O-Kanaloa to deploy perilously close to a reef.

“It’s a horrible way to search,” Mr. Gillespie said.
“It’s like you’ve lost your car keys at night in your backyard and you’re looking for them through a toilet paper roll with a flashlight.”
At the university, Dr. Wiltshire cited plans for bringing Alvin and the Nautilus rovers to explore newly created Pacific marine monuments.
Rates for Nautilus are in the range of $35,000 to $40,000 a day, while Alvin and its support vessel Atlantis II cost $60,000 to $70,000 a day.
HURL can deploy both Pisces subs for $48,000 a day, “and that’s not counting the transit time and expense to get there,” Dr. Wiltshire said.
“It takes us 15 days, but it takes two months to bring those ships over from the East Coast.”
Dr. Ballard countered that comparison must take into account the time his rovers can stay submerged — days at a time, as opposed to eight hours or so for Pisces or Alvin.
Dr. Bowen, who oversees the robotic and piloted programs for Woods Hole, says piloted exploration still has plenty of benefit.

Operating two of only eight deep-diving submersibles in the world, the Hawaii Undersea Research Laboratory (HURL) at the University of Hawaii - Manoa provides science and engineering communities with safe and efficient, cutting edge submergence capability.
A regional center in the NOAA Office of Ocean Exploration and Research, HURL supports proposals to conduct undersea research in offshore and nearshore waters of the main and Northwestern Hawaiian Islands and waters of the central, southwestern, and western Pacific, including the new marine national monuments.

“There’s no question that the strong suit for robotics is that you can engage a larger number of people in the process of exploration and discovery,” Dr. Bowen said.
But taking in all the undersea factors — currents, sounds, land forms, interactions between animals and their environment — humans are still far better at synthesizing what’s going on in the deep sea, he said.
“We hear that all the time from researchers who have looked at the video monitors and data screens from Jason, but then also gone down in Alvin.
It’s stunning how different their perception of the environment is.”
According to Craig McLean, the assistant administrator for oceanic and atmospheric research at NOAA, decisions about HURL’s future were mainly a matter of budget constraints and emerging technology.
HURL was funded as part of NOAA’s National Undersea Research Program.
Scientists competed for NOAA-backed studies, and the agency maintained and provided the equipment — like Pisces submarines — to the winners.
That program was phased out in favor of an unpiloted, Internet-connected virtual model that includes on-call scientists around the world.
“We realized we can’t afford to do it all,” he said.
“So we had to ask, what are we doing and how can we have it be inclusive? So scientists who can’t dive — they have a presence through telepresence.”
In addition to making headlines with discoveries of bizarre creatures, surveys with the Okeanos have, he said, had more practical applications.
A fisheries survey, for example, resulted in the recent protection of 38,000 nautical square miles of ocean off the East Coast.
Mr. McLean said that should a scientist bring a proposal before NOAA or the National Science Foundation that Pisces was well suited for, Mr. Kerby’s team could still get funding on a mission-by-mission basis.
He further agreed with a sentiment expressed by Dr. Earle, that in a time of dramatic changes in the climate and ocean itself — some 90 percent of which remains completely unexplored — he would prefer that NOAA had a wider arsenal of discovery at its disposal.
“We’re doing as much as we can,” he said.
“But we have to get into these difficult situations where we have to make our priorities.”
In the meantime, Mr. Kerby and his maintenance chief, Steve Price, have been hustling.
Mr. Price has been funded to compile a database of all Pisces discoveries for use by NOAA.
A World War II documentary project has kept Mr. Kerby busy lately, and a series of geology, undersea cable and sewer outfall surveys will keep HURL funded through year’s end.
He says he is confident more work will materialize, preventing his crew from having to follow the route of many former colleagues into oil and gas exploration.
He’d love to secure the resources not only to keep his subs running, but to add a full-time robot sub to HURL’s fleet.
“An associate of mine at Woods Hole upper management said, ‘HURL doesn’t stand a chance,’ ” Mr. Kerby said.
“ ‘They’re too far from the flagpole.’Well, we are. We’re way out here on the ocean frontier, in the prime spots, and we’re one of the most cost-effective operations around. With all the new and unexplored monuments in the western Pacific, and all the groups that need to do that exploration, we’re the only viable tool with experience in these environments.”
He paused.
“We know what we can do.”

OpenROV Trident - An underwater drone for everyone

OpenROV Trident - An Underwater Drone for Everyone
The future of ocean exploration is here.

From KickStarter

After four years designing and piloting underwater drones, we've taken everything we've learned and completely re-imagined what an underwater drone could be.
Trident has a unique design that combines the versatility and control of an ROV (Remotely Operated Vehicle) and the efficiency of an AUV (Autonomous Underwater Vehicle).
It can fly in long, straight survey lines called "transects" as well as perform delicate maneuvers in tight spaces, all while maintaining a sleek and powerful form factor.
Trident is easy to use and comes ready to go.
Most importantly, it is incredibly fun to fly.
(Flying really is the best term, because that's exactly what it feels like when you're piloting.)


Our Story

You may remember us.
We came to Kickstarter three years ago and shared our dream of building a low-cost underwater robot that would allow anyone and everyone to explore the world below the surface.
We have come a long way since that initial Kickstarter video.

We were working out of Eric's garage at the time, building the original prototype to explore a cave in Northern California with rumors of lost treasure (the full story can be heard in this TED talk).
We never found the gold, but we received messages from people all over the world who wanted to help us and improve the robot.
The Kickstarter project was the springboard. Since then, we've shipped thousands of OpenROV kits to people all over the world.

Community

The OpenROV community is the secret sauce.
We made our project open source in order to facilitate faster innovation cycles and allow others to improve on our initial designs.
Thousands of people have gotten involved.
You can see and follow along with the community expeditions on OpenExplorer.


Team

We've also assembled a small team that works from our OpenROV HQ in Berkeley, CA to manufacture, ship and support the robots.
The combination of community wisdom and the commitment of our internal R&D team (many of whom were original Kickstarter backers) have been the drivers in creating Trident.

At OpenROV, we talk openly about our desire to maximize "Return on Adventure."
We want to make sure that everyone who comes in contact with our project - community members, customers, employees, whoever - feels that their world is more interesting and more exciting because of it.
We want to give people a sense of wonder about how much out there is yet to be explored and make it possible for anyone to be a part of exploring it.
Trident is our best attempt yet to fulfill that promise.

Trident Performance


Every aspect of the Trident design has been painstakingly thought out in order to optimize performance and usability in any situation.
One of the secrets of its versatility is the unique, hydrodynamically offset thruster design.
This configuration allows you to move through the water fast and efficiently when you want to rapidly search an area or run a transect, but also allows you to maneuver very delicately when in tight quarters or while looking at a particular target.
By taking advantage of drag's exponential relationship with velocity, the off-center vertical thruster of the ROV can cause it to pitch at high speeds but also hover or change depth without pitching while operating at low speeds - similar to the way a traditional ROV works.


 We've designed Trident to be ultra portable and ultra durable.
The form factor is small enough to fit in a backpack or fit under an airplane seat.
The side panels are overmolded with a strong, rubber coating, which gives it protection from underwater obstacles as well as rough handling when being transported.


Depth: Capable of 100m (will ship with a 25m  tether - longer tethers will be sold separately)
Mass: 2.9 kg
Top Speed: 2 m/s
Run Time: 3 hours

The data connection to Trident is a major evolution from the connection set up of the original OpenROV kit.
It uses a neutrally buoyant tether to communicate to a towable buoy on the surface (radio waves don't travel well in water) and the buoy connects to the pilot using a long range WiFi signal.
Using a wireless towable buoy greatly increases the practical range of the vehicle while doing transects and search patterns since a physical connection between the vehicle and the pilot doesn't need to be maintained.
You can connect to the buoy and control Trident using a tablet or laptop from a boat or from the shore.

Software

Our goal is to make the easiest, most intuitive telerobotic control system possible.
We have embraced the latest emerging internet standards from HTML5 and webRTC to WebVR and WebGL to deliver a rich piloting experience through just a browser that runs on laptops, tablets, and modern mobile devices.


The software that drives Trident is a living open-source project (https://github.com/openrov/openrov-software).
The same software that drives our previous ROV has been continually updated by both the community and our software team. Some of those changes included:
  • Software plugins that allow any ROV enthusiast to deliver improved ROV capabilities to the whole OpenROV community via small Internet delivered update packages. 
  • UI Themes so that you can change the look and feel of the piloting experience. 
  • Depth and Heading hold. Until recently, only a feature on high end industrial ROVs, now available to everyone.
With Trident we are focused on an amazing out-of-the-box experience.
We are reviewing every bit of the user experience regarding our software to ensure the most simple and intuitive experience possible.


What's included

In each of the reward levels for a Trident, the basic package will include:
  • Trident. The actual drone, ready-to-dive.
  • A 25m (82 ft) tether. There's a lot to see in the first 25m of depth. For many people, that will be enough. Tethers will be removable and upgradeable if you need to go deeper.
  • A wifi topside buoy. The tether connects to a wifi topside buoy. You can use this to control the ROV remotely by setting it on the water or just leaving it on the boat or dock. 
  • Batteries. Trident comes with onboard LiFePO4 batteries, providing a run time of over 3 hours.
ADVENTURE SET ADD ON* (add $350 to any pledge level):
*
You can always get this later if you're not sure. Or only add for either the hard case or longer tether.
  • Hard Case. ($100 Add On) Trident will come in a sturdy package/box, but the Adventure Set will have a hard case for travel and shipment.
    AND/OR
  • 100m Tether. ($250 Add On) Know you want to go deep? Get the 100m tether right out of the gate.
Use cases

We built Trident to be the ultimate tool for explorers.
But we also wanted to make sure that it was useful for a whole host of utilities.
One of the most interesting new features - something that sets Trident in a class of its own - is its ability to conduct long transects, meaning it can run lawn mower patterns over large areas.
The benefit of this type of coverage is that you can create visualizations of what the seafloor looks like using photogrammetry software to create a 3D model of the work area.
Here's an example from the Fiskardo Greece Expedition run by our friends at OCTOPUS Foundation and Novalta:

Mission Fiskardo 2015 (Greece)
In the Northern part of Kefalonia island in the Ionian sea, Ocean71, Novalta and Fiskardo Divers

When overlaid on top of aerial drone footage, these visualizations create a "window on the sea."


It's also a great tool for boat owners and fishermen.
Whether you want to inspect an anchor line or look for shipwrecks, Trident gives you eyes underwater and adds a whole new dynamic to the experience of being on the water.


Sponsor a High School
"The OpenROV project was a winner -- igniting my inner city students' enthusiasm for exploration, taking on academic and technical challenges and developing resilience to over-come set-backs."
-Katie Noonan, Oakland High School


One of the most exciting parts of the OpenROV project has been the number of high school classes and students that have taken part.
The project provides an incredibly well-rounded education experience: mechanical and electrical engineering, programming, physics, biology, ecology, contributing to an open source community, and just getting outside into nature.
The OpenROV kit (not Trident - the previous model of kit) is still an excellent tool for education (and other uses that require the hack-ability).
We have a long list of well-deserving classrooms that can do wonders with a donated OpenROV kit. The reward pledge at the $1,000 level will further our efforts here.
It will allow us to send a kit and build materials to one of these schools.
If you're a resource-constrained teacher who'd like to be added to this list, please email info@openrov.com with the subject "I'm a teacher!"

Where We're At


We have spent the last two years developing the Trident, engineering dozens of prototypes to get to what you see today.
We are currently working on refining the final design and tuning it for manufacturing with veteran mechanical engineers and industrial designers.
We have developed relationships with manufacturing partners for the components and subsystems of Trident and now we need your support to help make it a reality!
