A total of 8188 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI2 mooring carried 10 hydrophones: HM511 (336m), HM512 (327m), HM513 (318m), HM514 (309m), HM515 (300m), HM516 (291m), HM517 (282m), HM518 (273m), HM519 (264m), HM320 (255m). A total of 4358 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI3 mooring carried 10 hydrophones: HM521 (317m), HM522 (308m), HM523 (299m), HM524 (290m), HM525 (281m), HM526 (272m), HM527 (263m), HM528 (254m), HM529 (245m), HM330 (236m).

A total of 8189 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI5 mooring carried 9 hydrophones: HM542 (565m), HM543 (556m), HM544 (547m), HM545 (538m), HM546 (529m), HM547 (520m), HM548 (511m), HM549 (502m), HM550 (493m). A total of 4359 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Mar 2016. Each acoustic recording covered 130 s with sampling rate 1000Hz. 10-, 50- and 90- percentiles of sound pressure and power were calculated for each reception using 50 % overlapping Hanning window with a window length of 1024 samples. The units for sound pressure is Pa. The unit for power (ocean sound level) is dB re uPa2 Hz-1. Noise by cable strumming is included. The processing is described in Geyer et al. 2021 https://doi.org/10.1121/2.0001507.

UAK - Active and Passive Acoustic data - 25 Jun 2020
Ambient sound was measured in Storfjorden, Svalbard at frequencies from 30 to 24000 Hz at depths from 4 to 20 meters. The measurements were carried out near land and melting ice bergs. The measurements were carried out using a drifting small boat, where the engine was turned off. Thereafter, a second small boat was used for transmitting pings at 11 kHz towards the first small boat at different depths and ranges. The experiment was carried out in June 2020 by Master students under supervision, as part of a research school in the Barents Sea with K/V Svalbard, organized under the UAK project lead by the Nansen Environmental and Remote Sensing Centre.
