Abstract:

A Slocum glider was deployed to collect oceanographic and acoustic data in the area surrounding three mooring sites. Acoustic data was collected on two recording systems (96 kHz sampling on internal, 288 kHz sampling on external; one channel on each) for 10 days in October 2015. CTD data were collected concurrently.

Purpose:

Acoustic data was collected in the vicinity of deployed bottom-moored hydrophones to compare odontocete detections on passive acoustic platforms. CTD data was collected concurrently to calculate sound speed profiles to determine sound propagation.

Data Parameters and Units:

latitude (deg_dec), longitude (deg_dec), depth (m), pressure (bar), timestamp (s), temp (C), salinity (PSU), sound speed (m/s), acoustic pressure (micropascals; scaled), conductivity (S/m), date (MM/DD/YYYY), time (local time, Central time zone - UTC -6 hrs)

Instruments:

Slocum glider with internal Tascum recorder and external SoundTrap recorder
