How Stable is this Sea Ice?
Two U.S. Coast Guard members are being transported by crane from U.S. Coast Guard Cutter Healy onto a piece of multi-year ice. 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.

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.
