EK80 Water Column Sonar Data Collected During SME140-201901 Deployment

Description

A bottom moored echosounder was deployed at 137.6 m depth in the NW Bering Sea (61.06918 N, 177.73993 W) from 26 July 2019 to 31 August 2020. The mooring was instrumented with a battery powered EK80 wideband autonomous transceiver (WBAT, Simrad AS). The echosounder operated an upwards facing depth-rated 70 kHz 18° split-beam transducer (ES70-18CD), positioned upward with a two-axis gimbal equipped with a 0.7 kg counterweight. During the deployment, the WBAT was programmed to transmit an ensemble of 320 narrowband and 35 wideband every two hours. Data were recorded to a range of 155 m. Calibrations had occured in Seattle, Washington either prior to deployment or after recovery using a 38.1-mm tungsten carbide sphere following the standard sphere method (Demer et al., 2015).
