The Atlantic Ocean, 480 miles southwest of Lisbon – The seas have laid down to a meter in the past 24 hours and (for the moment) the sun is filtering through a gathering cloud layer. We have just sailed south of the Madeira Islands, destination (slowly) Puerto Rico. It should take another ten days or so.
Of all the places I’ve traveled this is my favorite place to be: In the blue heart of an ocean, surrounded by nothing but sea and horizon, eyes locked on that place where blue meets blue. It could be the center of the Pacific or Indian, the Arctic or Southern, any ocean will do. Today, it’s the Atlantic.
Thinking on my feet as I ran through the airport I grabbed a copy of Simon Winchester’s new book called simply … “Atlantic.” (Its subtitle elaborates: “Great Sea Battles, Heroic Discoveries, Titanic Storms and a Vast Ocean of a Million Stories.”)
When I first heard of the project – the biography of an ocean? – it sounded quixotic. Now that I’ve paged through it, surrounded on all sides by the very same ocean Winchester describes, I’d use the word “unique.”
It’s a challenging task to try and wrestle such a vast, constantly changing place into even 500 pages. There’s geography to consider, all that human exploration and exploitation, the development of trade and slave routes, dozens of wars and the commerce that inevitably followed, by sea and air. Thankfully towards the end of the book Winchester manages to devote about a tenth of his research to man’s impact on the Atlantic, starting with the raping of the cod fisheries off New Zealand right up to the way ocean acidification is today altering its equatorial reefs.”The oceans are under inadvertent attack, and as never before,” he writes. “Insofar as the Atlantic Ocean is the most used, traversed and plundered of all oceans, so it is the body of water that is currently most threatened.”
He admits the Pacific has been heavily hit by similar abuses, but is convinced the Atlantic is in “greater trouble,” in part because it is so much smaller than the Pacific, was the first to be explored, crossed by man and is by far the busiest. “It has become evidently the least pristine and most begrimed,” he concludes.
Winchester puts big responsibility for much of that grime on the trailings of jet planes and smokestacks of ships. One hundred million air passenger crisscross the Atlantic each year leaving behind jet trails of kerosene, a heavy contributor to the carbon dioxide in the atmosphere. One stat is most telling: A fully loaded, 300 passenger Boeing 777 flying from London to New York spews 70 tons of carbon dioxide into the sky or about 2,000 pounds per person.
Ships leave behind a similar trail. Winchester quotes a 2007 report by BP and a German physics institute which says that the funnels of the world’s entire fleet of 70,000 fuel-burning cargo and passenger ships pour more carbon dioxide into the atmosphere than is currently produced by all of the nations of Africa combined. Half of that commerce takes place along the coastlines of the Atlantic.
One downside to the carbon dioxide created by ships –sulfur-laden soot and other particles created by the fossil-fuel burning exhaust — is that it creates its own low-level clouds that linger in the atmosphere for weeks and months. They are so dense they can be seen from space, from which they are called simply “ship tracks.”
(The biggest container ship afloat? The Danish Emma Maersk, which weighs 170,000 tons and carries 15,000 containers.)
Cleaner fuels will help slow the pollution, as might giant sails (computer-controlled, already in the experimental stages). Yet for now, Winchester concludes, “the degradation of the air above our ocean … is just one more of the egregious examples of modern man’s weary disregard for a sea he once revered.”
I put the book down on that note, agreeing with most of his conclusions, actually wishing there’d been more specifics about future options for transport of both cargo and man across the seas. But it is a heavy task to biography an ocean; not everything can be included.
Standing on the rail of my ship, ignoring for the moment the contribution it too is making to the ship tracks, looking out at the horizon line – where from this vantage, everything still looks quite pristine — I wonder to myself even as we gain more and more knowledge about the ways man impacts the ocean, do we really think there will come a day when we stop taking it for granted.
