Previously only small-scale scientific samplings have been staged in the Ross Sea. The survey was part of the International Polar Year program involving 23 countries in 11 voyages to survey marine life and habitats around Antarctica. The program hopes to set benchmarks for determining the effects of global warming on Antarctica, researchers said. Large sea spiders, jellyfish with 12-foot tentacles, huge sea snails and starfish the size of big food platters were found during a 50-day voyage, marine scientist Don Robertson said. Cold temperatures, a small number of predators, high levels of oxygen in the sea water and even longevity could explain the size of some specimens, said Robertson, a scientist with NIWA. Robertson added that of the 30,000 specimens collected, hundreds might turn out to be new species. Stefano Schiaparelli, a mollusk specialist at Italy's National Antarctic Museum in Genoa, said he thought the find would yield at least eight new mollusks. "This is a new brick in the wall of Antarctic knowledge," Schiaparelli said.
