Abstract:

A Slocum Glider was deployed in the eastern Gulf of Mexico off Tampa Bay in July and August 2016. As the glider traversed the transit path, it collected 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 the 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, then was processed and made available through the USF site including 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 datasets for this deployment included environmental water quality parameters, passive acoustic recordings, and echosounder water column data. The glider was deployed on 2016-07-29 at the 30 m isobath. It traversed for a week to the northwest before turning around and returning along a similar route to the southeast. It was recovered on 2016-08-12, near the deployment site. The intent was for the glider to follow the progression of the Gulfstream Natural Gas Pipeline, collecting water quality and acoustic datasets. 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 related datasets include additional results from this glider, M66, and gliders M69, M70, and M72.
