Abstract:

A Slocum Glider was deployed in the eastern Gulf of Mexico off Tampa Bay on 2017-01-03. As the glider traversed its transit path, it made measurements at various depths from ~2 m to near the seafloor or up to 200 m. While the glider was deployed at sea, it surfaced and communicated to an onshore control station at predetermined intervals. A decimated selection of vehicle and science measurement was transmitted during these surface transmissions, and the relevant data became 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 was downloaded from the vehicle and processed and also became available through the USF site as well as a national data archive. The measurements in this data set included acoustic tag telemetry detections of tagged red grouper and red snapper, as well as location fixes for the glider. Other data sets for this deployment included environmental water quality parameters, passive acoustic recordings, and echosounder water column data. The glider was deployed on 2017-01-13 at the 30 m isobath. It attempted to transit NW along the Gulfstream Natural Gas Pipeline; however, currents to the south prevented significant northward progress and eventually pushed the glider well to the south. It was recovered well south of Tampa Bay off Longboat Key on 2017-01-13. This dataset contains the tag telemetry receptions for a cohort of tagged red groupers and red snappers, as well as a fixed sound source. Other measurements available for this deployment include temperature, salinity, dissolved oxygen, acoustic biomass, and passive acoustic monitoring. Other related datasets include additional results from this glider, M69, and gliders M66, M70, and M72.
