Summary

At last month's Ocean Sciences Meeting in Honolulu, researchers described how they used mitochondrial genes to chart the evolutionary course of mussels from shallow water to the ocean floor. Shallow-water mussels, they showed, hopped from sunken wood to whale bones before settling in to cold bottom seeps--regions where hydrocarbons or salts ooze out of the ocean floor--and hydrothermal vents. Other presentations discussed the " fingered, not stirred " mixing of the ocean and a mood swing in the North Pacific.
