On a surprisingly mild December day, we left from a marina near the Rockaways, made a short run to the open ocean, and started to drift some 200 yards off the beach.
Goudey, the director of the MIT Sea Grant's Offshore Aquaculture Engineering Center, has devised a system by which giant spherical cages of fish would drift underwater in circular ocean currents, or gyres.
The exact location of the crash has not been determined, because ocean currents probably caused the bodies and debris to drift in the days since the crash.
Although continental crust is more or less permanent, the ocean floor is constantly recycled by the tectonic processes that bring about continental drift.
