Abstract:
A Slocum Glider was deployed in the eastern Gulf of Mexico off Tampa Bay in February and March 2017. As the glider traversed the transit path, measurements were collected 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 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 data sets for this deployment include environmental water quality parameters, passive acoustic recordings, and echosounder water column data. The glider was deployed on 2017-02-14 at the 30m isobath. It traversed for a week to the west-southwest before turning around and returning along a similar route to the east-northeast before turning to the southeast. It was recovered on 2017-03-09. The intent was for the glider to traverse across the WFS to the 160m isobath, and then follow the progression of the Gulfstream Natural Gas Pipeline with the intent of collecting water quality and acoustic data sets.
Other related datasets include additional results from this glider, M70, and gliders M66, M69, and M72.
