Shifting Outlines

How a map is drawn says more about the interests and intentions of the cartographers than it does about the space it describes.

Take, for example, these various maps of the Arctic. For most of human existence, the Arctic has been a place of myth, fascination and exploration. For a very few, it’s been home.

This first map is perhaps more interesting for its cartographical innovations (the use of the Mercator Projection) than its speculative geography that posits a whirlpool swirling around a black rock that represented the magnetic north pole. Note how closely identified and labeled the claimed territories are, how open and blank the rest is from the perspective of a European map maker.

This next one gets closer to my point of discussion today.

It shows outlines of the Arctic continent based on survey reports, and leaves out the parts that likely were not yet verified. More intriguing than the map itself are the surrounding illustrations of the riches to be found in the territory. Whales. It’s no surprise that this map is of Dutch origin.

Around the beginning of the 18th century, the Dutch moved many of their whaling operations from bays into the open sea. The Arctic, territory of ice and water, had a major energy resource for that era: whale blubber.

It was only later, when cheaper fuels took its place, that whale oil lost its primacy as an energy source (although it was still being used until the 1970s as, for example, automatic transmission oil in the United States and as a base for margarine).

Which brings me to this map, newly released by National Geographic. Actually, it’s modern and informative for a couple of reasons.

First of all, in its GIF presentation, it shows a trend rather than a static snapshot.

Second, that trend is concerned with the shrinking size of the Arctic, which makes this map a pointed commentary on climate change as much as it is a description of territory.

How that commentary is interpreted in other maps again illustrates our interests and desires.

Because the Arctic is shrinking, many assumptions made over the centuries can be re-evaluated. For example, the existence of a Northwest Passage, the long-sought sea route between the Atlantic and Pacific Oceans that is only now becoming truly navigable by large ships.

The ice shrinkage also means that more is accessible than new waterways. The sea bed, buried under ice, is now available for exploration. More importantly, for exploitation.

The Arctic has always been subject to territorial claims, but climate change renders those claims much more interesting to the five Arctic-bordering nations: United States, Denmark, Canada, Russia and Norway. All have been in the process of staking out the extent of their extended continental shelves for some time now, some more vociferously than others.

Under the United Nations Convention on the Law of the Sea (UNCLOS), these five countries can claim an extended continental shelf. If the claims are validated, the countries gain exclusive rights to resources on or below the seabed of their respective extended shelf area.

Which brings me to this map, which outlines potential oil and gas reserves on the Arctic sea bed.

And this, really, is what it’s all about.

The Arctic region has been estimated to hold up to one-quarter of the world’s undiscovered oil and gas reserves – energy resources almost as outdated as whale oil.

Small surprise, then, that Russia dropped a flag on the Arctic sea bed in 2007. The country has been pushing to claim 1.2 million sq km (463,000 sq miles) of the Arctic shelf.

Which is to say, all of it.

What better way to take advantage of the effects of climate change in the Arctic than by mining it for the very fuels that are causing climate change in the first place?

It looks like the changing Arctic outlines could force a redrawing of the maps in more ways than one.

Massive anchovy swarms off the coast of California have kept marine mammals and their observers busy for the past couple of months. It’s not so much that there are more anchovy than usual, it’s that there are more anchovy gathered in one place.

According to this article, anchovy movement can be due to a number of factors – plentiful plankton, mild temperatures – and this year, the anchovy stars aligned over Monterey Bay. Their presence, telegraphed far and wide via whale song, has set off a feeding frenzy of seals, whales, dolphins, and the press.

Anchovies and other small fish are known as ‘bait fish’ or ‘forage fish’, and form a key element in the marine food chain for mammals and the larger fish that humans prefer to see on their dinner plates. Some have recommended that humans switch away from the larger fish, which are being hunted by vast fishing fleets, to these smaller forage fish for human consumption.

Currently, we fish bait fish for use as feed to the other animals we prefer to eat – pigs, chickens, salmon. The ratio of forage fish feed to salmon, however, is around 5:1. Not very efficient. But the smaller fish, which tend to be oily, just aren’t popular for human consumption.

Anyway, the whales do exactly what human fishermen when they come across a bounty like this – they keep fishing until they’re full, or the fish are gone.

Here’s a very cool short clip, created by Robert Hodgin for the Auckland Museum, of how a bait ball works (in this case, sardines).

The Shape of the Unknown

Yesterday, I wrote about the mythical monsters that once populated the marine realm on the way to uncharted territories. Today, I thought I’d look at images of creatures that might have inspired tales of monsters, at least in the retelling.

It doesn’t come as a surprise that whales inspired stories of awe. The humpback whale easily grows to be 12–16 metres (39–52 ft) long, around the length of the three ships Christopher Colombus sailed in search of new territories. In the late 20th century they became one of the standard-bearing animals for human impact on marine life.

Growing up to 3.6 m (12 ft) in length, the walrus impresses more through its massive weight and long tusks. During the 18th and 19th century, American and European sealers and whalers hunted the walrus into extirpation (local extinction) in the Atlantic. Here’s an image of a walrus from an ancient map:

Global trade in walrus ivory is restricted under the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). Although not listed as imminently endangered, the main danger to the walrus at this point is habitat alteration due to climate change.

The Giant Octopus earns its name. Little is known about its habits, but individuals have been found that were over 4m (14 ft) in length. Not large enough to take down a ship, but an impressive sight nonetheless. Little is known about this octopus, which has proven an elusive object of study.

Thus, while it is known to be highly intelligent and a successful hunter of anything in its size range (including birds), and sensitive to polluted water, it is not considered endangered simply because too little is known about its population.

I try to imagine trying to describe these animals to someone who had never seen them in an era before photographs and mass communication, before most people had traveled farther than they could walk in a few days.

Would I emphasize the strangeness of the new creatures, make them sound even more fear-inspiring than they were, or would I talk about their unusual grace, impressive speed and unaccustomed movement?

Would the shape of the unknown be a fearsome maw, or  a sinuous fin?
