Iken loads a sediment trap while I steady the bracket. At right, Kelly is holding the rope. All the brackets are tied to the same rope, and two brackets, each with two traps, are already down in the water. The traps are weighted at the bottom so they stay upright. Each pair of traps weighs about 10 pounds, plus there's a 10-pound weight at the bottom end of the rope. At this station, the brackets hung 50, 35, 20, and 5 meters below the ice. "Bye, babies," says Iken as the last traps go in. "See you in a couple of hours," says Kelly. "Yes, I sure hope so," says Iken.
Image of The Day caption:
Working out on the ice in the reassuring presence of the U.S. Coast Guard icebreaker Healy, scientist Katrin Iken (left, from the University of Alaska-Fairbanks)?assisted by technician Pat Kelly (right, University of Rhode Island) and science writer Helen Fields (center)? prepares a cylindrical sediment trap to hang below the ice and catch particles falling down through the ice-covered ocean. The three participated in a spring 2009 research cruise led by WHOI biologist Carin Ashjian, to study the productive ecosystem of the Bering Sea in a time of changing climate.
