Like a deep-sea bloodhound, Sentry — the newest in an elite group of unmanned submersibles able to operate on their own in demanding and rugged environments — has helped scientists pinpoint optimal locations for two observation sites of a pioneering seafloor laboratory being planned off Washington and Oregon.

Inside the Arctic Circle, scientists have found black smoker vents farther north than anyone has ever seen before. Dissolved sulfide minerals that solidify when vent water hits the icy cold of the deep sea have, over the years, accumulated around the vents in what is one of the most massive hydrothermal sulfide deposits ever found on the seafloor.

The UW Board of Regents last week received a preliminary blueprint for a new college that will position the UW to be the leader in environmental research and education, and to better resolve complex regional, national and international environmental challenges, according to Provost Phyllis Wise.

In a pair of companion papers in Science Express this week, scientists investigate the role of surface meltwater on accelerating the flow of the Greenland Ice Sheet and outlet glaciers and conclude that, while surface melt plays a substantial role in ice sheet dynamics, it may not produce large instabilities.

Smash ice, turn your tongue into a salinometer to experience how saltiness differs in the world’s oceans, explore an igloo and field camp, predict polar climate, dive into the world of oceanographic moorings and get your hands on real scientific instruments during the third annual Polar Science Weekend today through Sunday at Pacific Science Center.

“Universities have a huge role to play in raising public awareness about climate change,” says LuAnne Thompson, University of Washington associate professor of oceanography and lead organizer of the UW events being conducted as part of Focus the Nation, a national teach-in on global warming solutions for America.
