ARCTIC OCEAN – Dr. Jason Gobat, an engineer with the University of Washington, Seattle, tightens a fitting on a Seaglider Saturday, Oct. 6, 2018, in the science lab aboard the U.S. Coast Guard Cutter Healy (WAGB-20) approximately 550 miles northwest of Barrow, Alaska. Gobat has been the lead engineer developing the Seaglider since 2001 and is in the Arctic deploying a series of Seagliders in support of a research project for the Office of Naval Research studying stratified ocean dynamics. A Seaglider is an autonomous, buoyancy-driven underwater vehicle used to take scientific measurements in the ocean, and it transmits that data back to researchers at the Applied Physics Laboratory at the University of Washington.
