Instruments

Seaglider

Supplied Name:

Supplied Description:

Southern Ross Sea, bounded by -77.438 and 167.73E, and extending to 76.771 and 171.98E; the glider made repeated short transects in a restricted area using a repeated bow-tie?/V-shaped? pattern.

Instrument Type

Generic Name: Seaglider

Generic Description:

The Seaglider is an autonomous underwater vehicle developed through a collaboration between The Applied Physics Laboratory -University of Washington and the University of Washington School of Oceanography. These small, free-swimming vehicles can gather conductivity-temperature-depth (CTD) data from the ocean for months at a time and transmit it to shore in near-real time via satellite data telemetry. Seagliders make oceanographic measurements traditionally collected by research vessels or moored instruments. They can survey along a transect, profile at a fixed location, and can be commanded to alter their sampling strategies throughout a mission.
