Two U.S. Coast Guard members are taking pictures of Arctic sea ice. They were lowered down from the U.S. Coast Guard Cutter Healy during an expedition to map the Arctic seafloor.

Two U.S. Coast Guard members are checking the stability of a piece of multi-year Arctic sea ice. They were lowered by crane from U.S. Coast Guard Cutter Healy. This was during a scientific expedition to map the Arctic seafloor. The expedition was a joint effort using two ships, Healy and the Canadian Coast Guard Ship Louis S. St. Laurent.

A member of the U.S. Coast Guard is preparing the Conductivity Temperature Depth Profiler (CTD) to be deployed in the Arctic Ocean to collect data.

This is the top of the Conductivity Temperature Depth Profiler (CTD). When the instrument is lowered into the water and reaches a desired depth, an electronic signal is sent along these wires from the ship that closes the bottles and a water sample is collected.
