Two Miles deep trailer
Syndicated cartoonist Jim Toomey is best known for his daily comic strip “Sherman’s Lagoon,” which explores themes ranging from pop culture to ocean conservation through the eyes of a cast of sea creatures living in an imaginary lagoon.
In June of 2014, Jim was invited by the Duke University Marine Lab to be a “cartoonist-in-residence” aboard the famed deep submersible vehicle Alvin.
“Two Miles Deep” is an account of his dive to the bottom of the Gulf of Mexico.
In this 27-minute film, we discover, from the perspective of a cartoonist, through video and animation, that the deep ocean is a world full of beauty and complexity.

Cape Horn discovered 400 years ago

From Maritime Executive by Niek Boot
On January 29 2016, it is exactly 400 years ago that a Dutch merchant ship, the Eendracht, sailed by Cape Horn, the southern-most point of South America.
When Fernando Magallanes discovered and sailed the Strait of Magellan in 1520 it was still assumed that Tierra del Fuego, the southern bank of the Strait, was part of Terra Australis, the unknown continent. Maps of the era show no passage south of the Strait of Magellan.
Some 80 years later, in 1602, the Dutch established the Dutch East India Company (the Verenigde Oostindische Compagnie or VOC) and granted it a monopoly to trade with the “Spice Islands” east of Cape of Good Hope and west of the Strait of Magellan.

One of the founders and the first president of the VOC was Isaac Le Maire.
He soon fell out with the board and was expelled in 1605 with the prohibition never to trade in VOC territory.
For a number of years he complied, but then the temptation became too great and he got permission to establish an “Australische Compagnie” or “South Company” and to launch an expedition to investigate the possibility of trade with the unknown Southern Continent.
His intention, from the start, was to find a new way to the East Indies, bypassing the exclusive routes of the VOC.
He purchased two vessels, the Eendracht (about 40m (130 feet) long with a crew of 65) and the Hoorn (about 30m (98 feet) long with a crew of 22) and had them fitted out by Captain Willem Schouten.

They sailed from the city of Hoorn, which was an important investor in the adventure, in June 1615. After calling at Cape Verde and Sierra Leone in Africa to replenish stores, water in particular, they arrived at what is today Puerto Deseado in the South of Argentina early December.
It is a protected inlet with a tidal range of over five meters, ideal to ground the vessels and clean their hulls of molluscs and other growth.
The cleaning was done by scratching the hulls with burning grass and scrubs.
During this work the Hoorn caught fire, and when the flames reached the gunpowder room, the vessel exploded and was irretrievably lost.
All of the crew survived and they then spent some weeks recovering was could be saved to put it on board Eendracht.

On January 13, 1616, they set sail on the next leg of the trip.
They continued south past the latitude of the Strait of Magellan.
Here the coast of Tierra del Fuego forced them to sail eastbound in bad and cold weather.
Captain Schouten was tempted to abandon the search and set sail for Cape of Good Hope, unconvinced of the existence of a passage to the east and less secure without the assistance of his support vessel Hoorn.
Jacob Le Maire insisted, and they continued.
On January 24, they found an opening and against current, waves and wind they managed to sail through.

Today it is called Staten Island, just like the island at the entrance of the Hudson River in New York, both named in honor of the General Staten of Holland, the Dutch government at the time.
1633 map of Strait of Magellan, showing Strait Le Maire at the right, marked Fretum le Maire (Latin) and Straet Le Maire (Dutch)
They called the passage “Strait Lemaire.”
Continuing south, they sailed by various islands, some of which still today carry the names they were given then.
On the afternoon of January 29, 1616, they came by a cape which they realized was the southernmost of all and called it Kaap Hoorn in honor of the city they had sailed from.
They crossed the Pacific Ocean and arrived in Djakarta on the island of Java at the end of October 1616.
Instead of congratulating them with their discovery, the VOC-appointed governor did not believe their story and confiscated their ship and the goods on board.
Le Maire, Schouten and some of the crew were shipped to Holland as criminals for having infringed the monopoly of the VOC.
Jacob Le Maire died on board at the end of December.
The others arrived in Holland by July 1617. Isaac Le Maire was of course most distressed for having lost his son and his ships.
He claimed against the VOC for the confiscated vessel.
He won the case and recovered 65,000 florins.
But in the meantime the Dutch set up a new company, the West India Company, which they granted the monopoly of trading with the Americas, including the route via Cape Horn.
As a result Le Maire could not take advantage of his son’s discovery.
He died a bitter man in 1624, but his name lives on, 400 years later.

Why we’ve been hugely underestimating the overfishing of the oceans
What if everything we know about the amount of fish in the ocean isn't true?
What if the quantity of fish we catch is much higher than we realize?
What if we're heading for a global fishing catastrophe that could trigger a food crisis for millions?
In a multi-year investigation, an international team of scientists led by Dr. Daniel Pauly has set out to challenge dangerous assumptions about the amount of fish we remove from the oceans.
Dr. Pauly contends that as governments and regulators report on commercial fishing, and claim the oceans can handle the huge catches - they're wrong.
The official data fails to account for entire categories of fishing, including small-scale, recreational, and illegal fishing (collectively known in the industry as IUU fishing).
If we don't know how many fish we catch?
How can we know that there are enough left?
The fate of one of humanity's most important food sources depends on convincing governments and industry to finally take stock of the missing fish.
"The Missing Fish" film will follow the journey of Dr. Daniel Pauly and his team as they gather information to calculate the world’s total fish catch.
The film is scheduled for release later this year.
From WashingtonPost by Chelsea Harvey
The state of the world’s fish stocks may be in worse shape than official reports indicate, according to new data — a possibility with worrying consequences for both international food security and marine ecosystems.
A study published Tuesday in the journal Nature Communications suggests that the national data many countries have submitted to the UN’s Food and Agriculture Organization (FAO) has not always accurately reflected the amount of fish actually caught over the past six decades.
And the paper indicates that global fishing practices may have been even less sustainable over the past few decades than scientists previously thought.
The FAO’s official data report that global marine fisheries catches peaked in 1996 at 86 million metric tons and have since slightly declined.
But a collaborative effort from more than 50 institutions around the world has produced data that tell a different story altogether.
The new data suggest that global catches actually peaked at 130 metric tons in 1996 and have declined sharply — on average, by about 1.2 million metric tons every year — ever since.

The effort was led by researchers Daniel Pauly and Dirk Zeller of the University of British Columbia’s Sea Around Us project.
The two were interested investigating the extent to which data submitted to the FAO was misrepresented or underreported.
Scientists had previously noticed, for instance, that when nations recorded “no data” for a given region or fishing sector, that value would be translated into a zero in FAO records — not always an accurate reflection of the actual catches that were made.
Additionally, recreational fishing, discarded bycatch (that is, fish that are caught and then thrown away for various reasons) and illegal fishing have often gone unreported by various nations, said Pauly during a Monday teleconference.
“The result of this is that the catch is underestimated,” he said.
So the researchers teamed up with partners all over the world to help them examine the official FAO data, identify areas where data might be missing or misrepresented and consult both existing literature and local experts and agencies to compile more accurate data.
This is a method known as “catch reconstruction,” and the researchers used it to examine all catches between 1950 and 2010.
Ultimately, they estimated that global catches during this time period were 50 percent higher than the FAO reported, peaking in the mid-1990s at 130 million metric tons, rather than the officially reported 86 million.
As of 2010, the reconstructed data suggest that global catches amount to nearly 109 million metric tons, while the official data only report 77 million metric tons.
Overfishing causing global catches to fall 3X faster than estimated
This news can be interpreted as both good and bad news.
On the one hand, “it means that fisheries are more important than we think,” Pauly said — in other words, when catches were at their highest, they were producing more food for the world than scientists previously thought.
This is a plus for global food security in the authors’ eyes.
Overfishing and the subsequent decline of the world’s fish stocks can be a threat to the food security of cultures that rely heavily on fish — but Pauly suggests that if we implement better management techniques in the future that allow these stocks to replenish themselves, we may be able to feed more people than we thought, as the new data suggest.
On the other hand, the higher catch numbers also suggest that fishing has been even more unsustainable in the past than scientists thought.
And the world is now suffering the consequences, as the authors point out.
Their second major finding was that fish catches have been sharply declining from the 1990s up through 2010 — much more severely than the FAO has reported.
At first, the authors thought that these declines might be due to increased restrictions by certain countries on fishing quotas in recent years.
But when the researchers removed those countries from their calculations, they found that the catch data was still caught up in a downward trend.
“Our results indicate that the declining is very strong and the declining is not due to countries fishing less,” Pauly said during the teleconference.
“It is due to the countries fishing too much and having exhausted one fish after the other.”
The data indicate that the largest of these declines come from the industrial fishing sector.
To be clear, the research is not meant to assess the state of the world’s fisheries, Pauly added — but, nonetheless, the study does raise some important questions about fisheries management moving forward.

They also point out the importance of stock rebuilding — that is, enacting fishing quotas to cut down on overfishing and allow fish stocks to replenish themselves.
Such action may become even more important in the future, as additional factors — most notably, the effects of climate change — place even more pressure on global fish stocks, Pauly noted.
“In the future there will be another mechanism that will begin to play a role [in catch declines] — that is global warming — and it will be very difficult to separate from the effects of fishing,” he said.
So while a few countries have already implemented fishing caps, he predicted that the world will continue to see a sharp and continual decline in catch until better practices are enacted worldwide.
And this will be important to consider, not only for the health of the oceans, but for the health of the millions of people worldwide who depend on fish for their food and their livelihoods.
With good management, though, there’s room for optimism, Pauly suggested.
“The fact that we catch far more than we thought is, if you like, a positive thing,” he said during the teleconference.
“If we rebuild stocks, we can rebuild to more than we thought before. Basically, the oceans are more productive than we thought before.”

Henry Worsley’s journey wasn’t foolhardy – it was tremendous
Photo: Global Book Publishing Photo Library
From The Telegraph by Paul Rose (Base Commander of Rothera Research Station, Antarctica, for the British Antarctic Survey for 10 years)
In Antarctica, making the slightest
mistake can put your life at risk.
It is an unforgiving place.
Colder than cold, bleak, a vast wasteland of iciness, its deadliness stretches for thousands of miles.
It is an unforgiving place.
Colder than cold, bleak, a vast wasteland of iciness, its deadliness stretches for thousands of miles.
True, it has been explored and mapped.
Yet the minute you step out of your modern base, regardless of all your hi-tech equipment, you’re in exactly the same Antarctica that Scott and Shackleton travelled in.
It’s remote and it is hostile.
Yet the minute you step out of your modern base, regardless of all your hi-tech equipment, you’re in exactly the same Antarctica that Scott and Shackleton travelled in.
It’s remote and it is hostile.
That’s why Henry Worsley’s attempt to follow in Shackleton’s footsteps and travel across the Antarctic alone,
pulling his own supplies, was so impressive.
He was a formidable explorer: well-organised, determined and incredibly powerful – not one of those people who just goes off with a dream and not much of a plan.
His was a good expedition, and I followed him all the way.
It looked as if he was cruising it and sometimes he was even going like the clappers.
But you’ve got to remember those conditions.
Even walking outside at minus 40 degrees when you’re well-rested is a very, very cold, potentially deadly experience.
For Henry to face those conditions alone every day would have been incredibly tough.
He couldn’t take anything that would add unnecessary weight – such as a spare pair of gloves.
And everything you do in those bitter conditions takes effort.
Say you’re thirsty and want to get some water out of your bag.
You’ve got to get the bag off the sledge and unzip it.
But you’re wearing thick mittens for travelling – warmer than gloves, but offering less dexterity – and you’ve got to take the outer mitten off to reach the zip.
Where do you put that outer mitten to make sure it doesn’t blow away?
Even the simplest task can be fraught with danger, and the only way to stay alive is with a severe amount of discipline.
It’s bloody hard at the end of a long day spent pulling that sledge.
All you want to do is get the tent up, get in and have a warm drink.
But the tent doesn’t go up by magic.
First you’ve got to secure the sledge, skis and poles so they don’t blow away.
You also have to bear in mind that the moment you stop you are instantly cold, so you have to put on a thicker, insulating down layer.
Then you find the tent and secure it – but it’s still just a shelter and minus 40 inside.
So you put the sleeping bag in, find the stove and melt some snow.
From stopping to getting a cup of instant soup takes an hour and a half.
Mornings are the worst, as you lie there, very hungry, tired and cold and have to force yourself to get up and start the routine over again: melt snow, make food, load sledge.
You love the sledge – because all that equipment is keeping you alive – but you are also beginning to hate the thing, the feeling of it rubbing on your hips as you struggle to put one foot in front of the other.
For all its harshness, though, Antarctica has something we love.Frank Wild, Shackleton’s right-hand man said that it calls you back with little white voices, and he was spot on.
Once you’ve worked there, it’s hard to resist its siren call.
Some people may say that Henry’s journey was foolhardy.
But it wasn’t.
For me it is only natural that we should want to explore new ground, no matter the dangers.
It is good for us to discover the “ground truth” of the planet for ourselves.
Henry’s was a tremendous journey and he very nearly made it.
For that, I salute him.

The final expedition:
A solo 943 mile
coast-to-coast trek across the Antarctic, pulling a sledge with
everything he needed. He collapsed 71 days into the anticipated 80 day journey, and later died of organ failure

Even the simplest task can be fraught with danger, and the only way to stay alive is with a severe amount of discipline.
His lifelong hero was Ernest Shackleton and it was his journey across the Antarctic that Henry Worlsley was trying to recreate - with the huge, added challenge that Worsley was entirely alone.
Like Shackleton, his bravery and his willingness to endure endless, uncharted terrain led him into a desperate race for survival that ended in his death
The British explorer died of organ failure - tragically - when the end of the mission was almost in sight - just 30 miles remained of his 1,000 mile journey.
