Getting a Grip on the Arctic

WHOI physical oceanographer Bob Pickart recovers a conductivity-temperature-depth (CTD) sampling rosette from a remarkably ice-free Beaufort Sea in September 2004. Pickart and colleagues have been studying the flow of waters into and out of the western Arctic, as well as how the layers of the sea are changing from season to season.
