Last night the ship paid another visit to the bloom that the scientists were looking at last week. As they've done every other day or so for the last month, the krill team dropped their bongo nets into the water to get animals for their experiments. This usually happens at about 2:30 a.m. The bloom had progressed-the water was full of chains of diatoms, a kind of microscopic phytoplankton. "It looks like they caught a cooler full of mud," says Tracy Shaw, of Oregon State University.
Image of The Day caption:
Researchers aboard the U.S. Coast Guard Cutter Healy gather samples collected from bongo nets during a May 2009 expedition to the Bering Sea. The netsalso known as twin plankton nets or ring netsare used to collect the miniscule animals that the group uses to study how climate change is affecting the region s ecosystem. Each net has a ring at the mouth of a cylindrical net that, when towed through the water, funnel zooplankton into a collecting bucket at the back.
