CTD profile instrumentation

Working among icebergs

Are warmer ocean waters affecting Greenland's ice sheet? To find answers, WHOI scientists this fall made use of a local, small vessel able to navigate the iceberg-filled waters of Sermilik Fjord in East Greenland to collect temperature and conductivity profiles up to 900 meters depth. They used this motorized fishing winch, mounted on a WHOI-built frame that was adjusted to the vessel, along with a CTD, which measures conductivity (salinity), temperature, and depth.
