The hidden world of salps.

OFF THE ANTARCTIC PENINSULA -- Biologists Larry Madin (WHOI) and Patricia Kremer (U. Connecticut) led a month-long cruise aboard the ice-strenghtened ship L.M. Gould to learn more about a little-known species of salps, a gelatinous, tube-shaped planktonic animal that may be getting more numerous in the Southern Ocean. Changes in the climate and sea ice around Antarctica may create conditions in which salps thrive instead of krill, a critical food for penguins, seals, and whales. Researchers used net sampling, scuba diving, lab experiments, and a prototype imaging instrument (LAPIS) to study salps' feeding, reproductive biology, and ecosystem impacts. The cruise was featured on WHOI's "Dive and Discover" Web site (
