The Coast Guard Cutter Healy is captured from a camera onboard one of two unmanned seagoing vehicles during a rendezvous between the vehicles and the crew aboard the cutter in the southern Chukchi Sea, Tuesday, Aug. 29, 2017.
The purpose of the rendezvous was for members of the science party aboard the Healy to calibrate specific instrumentation onboard the vehicles by comparing data from samples taken on the Healy to measurements taken by the vehicles.
