Dance of the Dumbo octopus


Ghostly ‘winged’ octopus caught on camera
This video features the Grimpoteuthis bathynectes species.
Sometimes nicknamed the Dumbo octopus,
its ears are really fins that help it move through the water.

From Wired

A rarely seen white deep-sea octopus has been captured on camera in high definition by researchers from the University of Washington.
The octopus features two “wings” which make it look just like the ghosts from Mario videogames, aka Boos.

The
Grimpoteuthis bathynectes octopus, also nicknamed the Dumbo octopus, was filmed with an HD video camera at a depth of more than 2,000 metres [6,500 feet] about 200 miles off the coast of Oregon in September 2005 as part of the VISIONS ‘05 expedition led by Professors John Delaney and Deborah Kelley of the University of Washington.

Little is known about the deep-sea octopuses, which live near the hydrothermal vent fields — fissures in the Earth’s surface generally found near volcanically active places that release geothermally heated water- associated with the underwater volcanoes of the Juan de Fuca Ridge in the Northeast Pacific Ocean.

Torrey Canyon seabed returns to normal after oil spill

Movement of oil from the wrecked Torrey Canyon
which spread in response to changing wind direction

From BBC

The seabed off the Cornish coast seems to have almost recovered after an oil tanker spill in 1967, writes Paul Rose, expert diver and presenter on
BBC programme Britain's Secret Seas.

The
Torrey Canyon is the largest shipwreck in British waters, and as she sits a long way from shore amongst the same hazardous rocks that she ran on to, its not the easiest wreck to get to.

On Saturday, 18 March 1967, she ran aground carrying over 119,000 tonnes of crude oil, which gushed out into the pristine Atlantic waters.
She had run into one of the infamous Seven Stones rock pinnacles, which lay 15 nautical miles west from Lands End and seven nautical miles from the
Scilly Isles, which make it a hard wreck to reach.

>>> geolocalization with the Marine GeoGarage<<<

We believe our team is the first to film the wreck, which is in an area often hit by storms.
As I rolled off the boat into heaving waters caused by constant huge Atlantic swells, I entered a great swaying underwater forest of kelp.
The water was gin clear and the huge kelp fronds were in a mad rhythm of bending, then standing straight up, swinging and heaving to the forces of the sea.

It was a great, vibrant start to the dive, but it looked to me as if we had missed the Torrey Canyon completely, as after all she is said to be well broken up over 2 sq km of the seabed.
I then realised that I was on the wreck - the huge hull plates have so much life on them that they look just like rocks or the bottom.
The sea has reclaimed the wreck and it is teeming with life.

Things started to make sense and as I swam along the steel plates I joined large schools of wrasse, pollock and pouting.
Some of the schools were moving purposefully along the wreck sides and others had relaxed into shoals underneath and inside the wreckage.

I used the big surges to drive me forwards and then I held on during the backwash so I made good fast progress around piles of machinery, winches and twisted steel plates all completely camouflaged with weed, anemones, briozoans, starfish and colourful urchins.

There was no single identifiable cause for the world's largest super tanker to run aground on the well-known and well-charted rocks.
But at time of the disaster the skipper had plotted a shorter than normal route, in effect cutting a corner, and it was the ship's cook who was on watch in the bridge.

There was widespread confusion about how to deal with massive spill.
The case has been recently likened to the Deepwater Horizon oil rig disaster in the Gulf of Mexico, which killed 11 people, and resulted in 4.9m barrels of oil being discharged, threatening marine life and hundreds of miles of coastline

A decision was made at the time to bomb the wreck and its oil slick in an attempt to burn the oil.
The Royal Navy were rallied and they led the bombing runs dropping 62,000lbs of bombs, 5,200 gallons of petrol, 11 high-powered rockets and an undisclosed amount of napalm on the wreck and the surrounding waters, sinking the ship, but not really dispersing the oil.

On my dive, as I whizzed round the corner of the superstructure I hovered over one of the many bombs that had been dropped on her.
I was relieved to see that it had exploded, but it was a healthy reminder that there are hundreds of unexploded bombs on and nearby the wreck.

The 20-mile long oil slick reached the Cornish coast in a few days triggering a massive environmental catastrophe including the death of over 25,000 sea birds.
The familiar golden sand beaches were totally black and no life existed on any of the sea cliffs.
In spite of cleaning car tyres and workers boots, the heavy black crude made its way into the streets, shops and homes.
The fumes could be smelt throughout Cornwall and with the bombers flying low making their runs to the wreck site one could be forgiven for thinking that a version of black hell had arrived.

There was a dire need to "do something" and so a huge clean up operation began including widespread use of detergents.
These were such aggressive chemicals that many of the beaches and cliff areas still show signs of their effects.

Six months after the spill some untreated beaches had returned to a pristine condition, whilst the treated beaches had become a wasteland.
Nineteen days after the wreck, its massive oil slick hit western Guernsey and in a reaction similar to the Cornish the authorities decided to act fast.

Tourism was the island's main source of income - the beaches had to be saved.
So in a desperate, fast and furious 11 days they managed to scour the beaches clean by collecting tonnes of the crude and dumping it into a disused quarry.
The beaches were saved, but a visit the quarry is a sobering experience.

Much of the oil has been removed and processed for use, but each time a large amount of oil is taken from the quarry, more seeps up from the sediment below and so the process has to start again.
The quarry cannot be dredged to clean it because during WWII, the Germans who occupied the island used it as an armaments dump and tonnes of unexploded ordnance remain.
In 2009 the water level rose and the change in pressure released yet more crude from the bottom.

But there is hope - both for Guernsey and for future oil spill clean up campaigns.
The Guernsey team are using a process called bio-remediation in the quarry, which uses naturally-occurring bacteria which eat oil as a food source.
These micro-organisms are pumped into the oily water 24-hours a day and it is hoped that in a year all of the oil will have been eaten.

Fishing for plastic to save our seas


An EU plan to pay fishermen to catch plastic will help save our waters from waste
while providing fleets with alternative income


From TheGuardian

Rarely has a TV campaign been won so convincingly.
In January this year,
Hugh Fearnley-Whittingstall's Fish Fight programme persuaded over 600,000 of us to support a ban on the wasteful practice of throwing dead fish back into the sea.
The European commission listened and has announced it intends to ban discarding fish.

For some peculiar reason, the fishing industry's reaction to the commission's announcement was not as warm as you might have expected.
A discard ban will put many out of business, we now hear, presumably because many of the fish caught as bycatch are smaller and less valuable than the ones fishermen land today.
So in announcing the plan,
Maria Damanaki, the European fisheries commissioner, sought to soften the blow.
Under her proposal,
fishermen may be paid to fish for plastic instead.

Plastic fisheries sound daft, but the idea is far from silly.
Our seas are awash with plastic bottles, bags, nappies, discarded fishing nets, ropes and thousands of other bits and pieces – the flotsam of modern life.
By 2008, the latest year for which I have a figure, 260m tonnes of plastics were made using 8% of global oil production in raw materials and energy.
The curve of production over time bends upwards like a cliff face, increasing by 9% per year.
The stark reality of this ever-steepening upward climb is that more plastic was made in the first 10 years of this century than all of the plastic ever created up to the year 2000.

Deliberate dumping of plastic at sea has been banned since 1998, but the law is hard to police.
The amount of rubbish picked from British beaches in cleanups sponsored by the
Marine Conservation Society increased 77% between 1994 and 2009, much of it chucked from ships.
Rivers add mindboggling amounts of plastic into the sea daily; much of it soon comes back to a coast near you.
Every year, about 2,000 items of rubbish (most of it plastic) washes ashore for each kilometre of beach in Europe.
The Mediterranean is worst affected with up to 18,000 pieces per kilometre per year, so it isn't surprising that the European commission plan to test their plastic fishing proposal there first.
Even the deep sea is not beyond reach.
About half of plastics sink, and submarine pilots regularly see bags float past 1,000 metres down.

Plastic at sea isn't just unsightly.
Many seabirds, turtles, fish and others mistake plastic for food: 19 out of every 20
fulmars that wash up dead onto European beaches have a belly full of plastic.
Adult birds pick up floating plastics at sea and feed them to their chicks.
If plastic was just harmless roughage it would be bad enough.
Instead, many plastics come loaded with chemicals like flame retardants, which get passed up the food chain and so can come back to us in the fish we eat.
Worse still, plastics accumulate toxic chemicals (such as pesticides found in water) and concentrate them to thousands of times background levels.
Over the years, floating plastics break into ever smaller fragments, making it easier to transfer their chemical burden to anything that eats it.
In some places, there is more plastic than plankton.

Fishing for plastic is a great idea.
It won't rid the sea of the microscopic soup already adrift, but it could stop things getting worse.
There is already a voluntary scheme,
Fishing for Litter, which provides collection facilities at ports where rubbish caught can be disposed of rather than thrown back over the side.
All of Scotland's major ports already participate.
Given that fishing nets sweep the majority of European waters every year, a dedicated cleanup could clear much of the accumulated trash within a few years.
But ultimately, the plastic problem will only be solved if we all use less and make sure none of it reaches the sea.

Mara Kerr inspire ocean awareness with new book

In her new novel, "Oceanus," author Mara Kerr tells a story about love, life, and water with the hope that it will inspire readers' ocean awareness.

From Oceanusthebook

It begins with David’s remarkable journey and his unique love affair with a mermaid named Coral.
Together, they decide to raise Coral’s mermaid daughter, named Jasmine.
David must teach Jasmine all about the current state of our oceans and the precious marine life living in it.
David understands that without the improved health of the oceans, both Jasmine and Coral’s chances for survival are not good.

David and his friends—Noah, Joshua, and Pete—introduce Jasmine to many fascinating marine creatures and teach her ocean awareness by traveling from California to Hawaii and to Bora Bora.

On the way to Bora Bora, David and his sailing friends run into a life-threatening storm; making matters worse are the dangerous pirates that attempt to steal their boat.
Coral and Jasmine face their own troubles during a scary kidnapping that endangers all the mermaids’ lives.

The time is now for saving our oceans.
It is true that ocean awareness can be generated through the heart.
Real inspiration has the power to change.
Our planet is suffering, and our oceans are being savaged.
Oceanus shows us the magnificent healing power of love.

“Did you know that the plankton in the ocean produce 50% of the world’s oxygen?”
And, did you know the plankton absorb over 20% of the carbon emissions being released into the atmosphere?
Learn more about amazing plankton by reading “
Oceanus."
The time is now to fall in love with the ocean, again & again & again…
When not busy writing,
Mara Kerr likes to produce movies as she did with "In the Wake of Giants," a humpback whale documentary awarded Best National Marine Sanctuary Short Film at the BLUE Ocean film festival.
Save our oceans with power of love…
