The hothead theory is that the ice on that gigantic island is much less stable than previously thought, and that with a tad more warming, lakes will form in the summer, drain thousands of feet down to the bedrock, and lubricate the flow to the ocean.

At these depths, everything must be done with remote-control robots that install the blowout preventers, submersible pumps and other devices to manage the flow of oil and water on the ocean floor.

Analysis of the ocean currents shows that for the past weeks, the general flow around the Hawaiian Islands has been from the southwest, producing a front 300 miles to 400 miles (483 to 644 km) northwest of Midway that has kept the debris north of the islands.

What goes for an airport or a bay can be scaled up to an ocean, or the air above it, and down to the flow off an aircraft's wingtip, or a ship's hull.
