WHOI engineering assistants Kris Newhall (left) and John Kemp pose in August 2004 with their gear after practicing the deployment of the winch and tripod support frame that they use to deploy ice-tethered profiling instruments.  Over the past four years, the research team has been placing these instruments in strategic regions of the Arctic Ocean to determine how the layers of water beneath the ice cap are changing with time.
