A Canadian helicopter pilot is discussing the helicopter's operations to U.S. Coast Guard members. The helicopter flew from the Canadian Coast Guard Ship Louis S. St. Laurent to the U.S. Coast Guard Cutter Healy. This is in the Arctic Ocean during a scientific expedition to map the seafloor.

A member of the U.S. Coast Guard helps guide the deployment of the Conductivity Temperature Depth Profiler (CTD) in the Arctic Ocean.

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.

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.

Robert Sanders, with Temple University, is collecting water samples from the CTD. Both Robert and Rebecca Gast, with Woods Hole Oceanographic Institution, were using the samples to study microorganisms in the Arctic Ocean.

The Conductivity Temperature Depth Profiler (CTD) is being lowered in the Arctic Ocean to collect water samples and measure conductivity and temperature as a function of water depth.

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.

Research excavation of a loggerhead sea turtle nest (Caretta caretta) on a sandy Florida beach. The excavation is part of a county research program that keeps track of the number of nests (by species) - mostly loggerhead, a few greens, and an occasional leatherback. They excavate the nest a day or two after confirmed hatching to count unhatched eggs, dead hatchlings that
