This picture of ship tracks off North America isn't at all what I thought from the title when it popped up in my feed reader. They're not 'tracks' as in a bow wave, but the trails of clouds that form because of the trail of aerosols – be it exhaust fumes or just desert dust – that a ship leaves behind it.
There's also a rather nice animation showing almost 12 hours-worth of the tracks' movement.

Stefany Anne Golberg contemplates how the ocean recycles our tragedies:
By next spring, [The US National Oceanic and Atmospheric Administration] announced, debris from Japan's tsunami could start washing up along the coast of Hawaii. In two years, it could travel to the West Coast of the United States – to Washington, California, Oregon. For two more years after that, from 2014 to 2016, bits of crushed homes, children's toys, fishing nets – up to 20 million tons of homeless stuff – could circle back to Hawaii. It might be, researchers say, that for the next 10 years, tsunami souvenirs could hover around coastal landlines, visiting the shores of America again and again.
