Coast Guard Chief Petty Officer Nathan Poppink secures a conductivity temperature depth rosette to the deck of the Coast Guard Cutter Healy during research operations in the Arctic, Friday, Sept. 8, 2017.
The equipment is secured so that members of the science party can safely retrieve water samples collected by the device, despite the motion of the cutter.
