Abstract:
ADCP and echosounder data recorded by a bottom mounted, upward facing Nortek Signature100, deployed at 250 m depth in the Kvitøya Trough, northern Barents Sea. The echosounder data are uncalibrated. Data were collected during two separate mooring deployments extending from 2019-11-16 to 2020-09-28 and from 2021-02-22 to 2021-11-10. The Nortek Signature100 combines a four-beam ADCP operating at 100 kHz and a central beam with a 70–120 kHz echosounder. The echosounder data are separated into 7 frequency bands: 70kHz, 73.8 kHz, 82.3 kHz, 90.9 kHz, 99.4 kHz, 107.9 kHz and 120kHz. Near bottom temperature and pressure data are also included. Data extend from approximately 14 m above the bottom to within 2 m of the water surface.
