Jason hits a snag

Location: Heading to Adak

Posted 08.09.04 at 1:26 am

The final Jason II dive of this leg of the cruise — the last during my time aboard—was abruptly cut short less than halfway through when the ROV stumbled across a derelict fishing line. (Biologists aboard think it was an old crabpot line.)

I watched as the crew brought Jason in close to the ship, then, by hand, hauled aboard a couple of hundred feet of line, freeing Jason so they could finish recovering the ROV. It looked as if the men were hauling in old, badly frayed rope.

On closer inspection, this line was full of life. What I’d thought from a distance was frayed rope turned out to be different kinds of soft corals and other creatures. 

Looking closer, I could even see clumps of thin, inch-long translucent animals, like little rice noodles with legs—waving those legs frantically in the air. On closer inspection, I could see they weren’t noodlelike at all, but more like insects—maybe tiny praying mantises. Biologist Scott France explained that these caprellid amphipods, commonly called skeleton shrimp, make their livelihoods this way, hanging from hooks on their back legs and gathering food.

Biologists made the best of the situation, taking samples of some of the corals; our plans were changed to limit the ship’s time in Adak, to give remaining science team members more diving time.
