Measuring Sound Speed with an XBT
A U.S. Coast Guard member is preparing to launch an Expendable Bathythermograph (XBT) to help calculate the speed of sound in the ocean. The launcher sends a probe into the water to measure depth and temperature variation below the ship. There is a copper wire attached to both the launcher and the probe.

Picturing Arctic Sea Ice
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.

U.S. and Canadian Ships in Arctic Ocean
Helicopter view of Canadian Coast Guard Ship Louis S. St. Laurent (top) and U.S. Coast Guard Cutter Healy (bottom) on the Arctic Ocean. The ships are coming together because the crews are planning to meet and learn the operations of the other ship. This was during a scientific expedition to map the Arctic seafloor.
