Sound Bytes: Synchronous Swimming (With Robots) – Behind the Glider Challenge

Sound Bytes

The exciting work of flying robots underwater takes science, teamwork, and flexibility.

Two people sit on the left and right sides of a bright yellow undersea glider while on a vessel in the ocean. They are wearing life jackets, sunglasses, and sun-protective clothing. The deep blue ocean is visible behind them. Dr. Selene Fregosi (right) and Jeremy Taylor, Pacific Islands Fisheries Science Center, supported NOAA Fisheries’ undersea glider challenge in Hawaiʻi in early 2026. The challenge assessed glider performance and capabilities in field conditions off Oʻahu. Credit: NOAA Fisheries/Calla Lloyd-Lim

A Tribute To Our First and Best Glider

Autonomous Gliders in the Antarctic

The first glider we ever deployed remains our most dependable.

Several people are in the boat and on the ship, attaching a rope to the glider so it can be lifted out of the water. The crew of the M/Y Hanse Explorer, alongside U.S. AMLR personnel, prepare to lift AMLR01 out of the water. Credit: NOAA Fisheries

What Is a "Five-Star Resort" for Antarctic Krill?

Autonomous Gliders in the Antarctic

Antarctic krill are our main research focus, so we need to learn all we can about their environment.

Boredom is the Root of All Evil … Unless You’re a Glider

Autonomous Gliders in the Antarctic

We just deployed two gliders and hope for an encore of last year’s near-flawless deployment.
