Salinity and temperature measurements from an oceanographic glider deployed in coordination with DEEPEND Cruise DP04, August 2016

A Slocum Glider was deployed in the northern Gulf of Mexico near the time of the DEEPEND cruise DP04 (August 10-17, 2016). As the glider traverses its transit path, it makes measurements at various depths from ~2m to almost 1000m. The measurements include conductivity, temperature, depth, pressure, and salinity. While the glider is deployed at sea, it surfaces and communicates to an onshore control station at predetermined intervals. A selection of vehicle and science measurement is transmitted during these surface transmissions, and the relevant data becomes available through a University of South Florida (USF) web site. After the glider’s recovery at the end of the deployment, the complete measurement suite is downloaded from the vehicle and processed, and also becomes available through the USF site as well as a national data archive. The data available during and after the deployment can help correlate the regional Naval Research Laboratory (NRL) hydrographic model and the satellite imagery to in situ measurements of subsurface water characteristics.
