A camera mounted on a rosette sampler captured this unusual view of the starboard A-frame of U.S. Coast Guard Cutter Healy from the water of the Beaufort Sea north of Alaska. The instrument collected water samples and carried a CTD sensor that measured depth, temperature, and salinity of the water at various depths. It was deployed by WHOI physical oceanographer Bob Pickart and colleagues as part of an annual survey of the western Arctic boundary current in an area where scientists are tracking how the current is responding to climate change and how that affects the region’s ecosystem.
