Teledyne Underwater Slocum Glider Maps Ocean Water Depths, Assays Biosphere

The Sacoora report notes that the Slocum glider has sensors that measure temperature, salinity, water color, backscatter, dissolved organic matter (CDOM), chlorophyll, and dissolved oxygen. Its wings enhance operational stability on missions that vary from storm forecasting to fisheries and algae bloom research to measuring the seasonal thermocline. It features a “900cc Hydraulic Flight Drive” and a “Pneumatic Surfacing Drive”.  The Teledyne Slocum glider is used by the military as well as researchers who study marine mammals; research partners include GCOOS, Mote Marine Laboratory, the College of Marine Science at the University of Southern Florida (USF), and others.

A bonus for oceanography ROV enthusiasts is that Slocum glider mission data can be viewed for FREE on GANDALF (Gulf AUV Network and Data Archiving Long-term Storage Facility). “While a glider is in the water, GANDALF provides real-time glider positioning information via a map-based interface with a dashboard display.” See the report for links to mission data.
