Eastern Gulf of Mexico glider deployment M72 (2017-05-16 – 2017-06-12) – tag telemetry receptions

A Slocum Glider was deployed in the eastern Gulf of Mexico off Tampa Bay in May and June 2017. As the glider traversed its 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, 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 included environmental water quality parameters, passive acoustic recordings, and echosounder water column data. The glider was deployed on 2017-05-16 at the 30m isobath. It traversed for a week to the northwest before turning west-northwest to the 150 m isobath, turned around and made its way back northeast before turning southeast and returning along a similar route to the east-northeast before turning to the southeast. It was recovered on 2017-06-12. The intent was for the glider to follow the progression of the Gulfstream Natural Gas Pipeline before and after a transect out to the shelf break, collecting water quality and acoustic data sets. Other related datasets include additional results from this glider, M72, and gliders M66, M69, and M70.
