Color image taken during daylight from the upper deck of a research vessel, facing toward the rear of the vessel as it sails through a canal. Land is visible on each side of the canal, and the ship leaves a wake in the water. Two steel framed bridges are in the image. The ship has just passed under the bridge used by vehicles. The railroad bridge is in the distance. View over the stern of the NOAA Ship Henry B. Bigelow, exiting the Cape Cod Canal headed east toward Provincetown, Mass. at the beginning of Leg 3 of the 2021 Northeast Fisheries Science Center fall bottom trawl survey. The two bridges spanning the canal are used by trains (background) and vehicle traffic (foreground. Credit: NOAA Fisheries/Katelyn Depot.

Preparing a Glider for Deployment: A Step-By-Step Guide

Autonomous Gliders in the Antarctic

It’s a long, meticulous process, but well worth it to make sure we don’t lose a glider or the data it collects.

large yellow and black glider suspended over pool Ballasting a glider in our ballast tank. Two spring scales are attached to either end of the glider to determine what it weighs in ocean water. We use a crane mounted on a gantry above the glider to lift the glider into and out of the water. Credit: NOAA Fisheries/Jen Walsh
