Abstract:

A Slocum glider was deployed in the eastern Gulf of Mexico off Tampa Bay in January 2017. As the glider traversed its 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 USF web site. After the glider’s recovery at the end of the deployment, much of 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 counts of the number of fish calls derived from passive acoustic recordings. Other data sets for this deployment included environmental water quality parameters, acoustic tag telemetry receiver detections, and echosounder water column data. The glider was deployed on 2017-01-03 at the 30 m isobath. It attempted to transit northwest along the Gulfstream Natural Gas Pipeline; however, currents to the south prevented significant northward progress and eventually pushed the glider further to the south. It was recovered south of Tampa Bay, off Longboat Key, on 2017-01-13. The suite of related datasets includes results from gliders M66, M69, M70, and M72.

Purpose:

Demonstration of fisheries-applicable datasets obtained by underwater gliders, including tag telemetry receivers, passive acoustic recordings, and echosounder derived water column acoustic backscatter. This dataset includes passive acoustic recorded red grouper calls collected by underwater glider.

Data Parameters and Units:

Date and time [MM/DD/YYYY HH:MM], Latitude [decimal degrees], Longitude [decimal degrees], number of recorded red grouper calls per one-minute period [enum].

Methods:

Recordings were made for one minute every five minutes.

Instruments:

Slocum Electric G1 glider (Teledyne Webb Research), with Vemco VMT.
