Lowered by Crane to Arctic Sea Ice

XBT Used to Measure Speed of Sound
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.

Conductivity Temperature Depth Profiler (CTD)
These are the lids both on top and below the water bottles on the Conductivity Temperature Depth Profiler (CTD). When the CTD is placed in the ocean and reaches a desired depth, an electronic signal is sent from the ship that closes the bottles and a water sample is collected.

Arctic Sea Ice
This is an image of nilas, which is thin ice, in the Arctic Ocean. As nilas comes together like fingers, which is known as finger rafting, it creates thicker ice called young ice.
