U.S. Coast Guard members aboard Coast Guard Cutter Healy [WAGB 20] stabilize a water-sampling device, while another crewmember directs a machinery operator to lower the mechanism onto the deck of the Healy during night operations along Barrow Canyon, Friday, Sept. 1, 2017. The device was an oceanography instrument primarily used to determine the conductivity, temperature, and depth of the ocean, as well as provide water samples from various depths for further analysis.
