Eastern Gulf of Mexico glider deployment M66 (2016-07-29 – 2016-08-12) – echosounder water column backscatter intensity

A Slocum glider was deployed in the eastern Gulf of Mexico off Tampa Bay in July and August 2016. 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 becomes available through the USF site including a national data archive. The measurements in this data set included water column biomass estimates and the raw echosounder water column backscatter intensity measurements. Other data sets for this deployment included environmental water quality parameters and acoustic tag telemetry detections. 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 data sets. The suite of related datasets includes results from gliders M66, M69, M70, and M72.
