UNDERICE: Ambient noise in water 08/09/2014-06/03/2016

Hanne Sagen

This dataset is based on acoustic recordings from five moorings deployed during the UNDER-ICE experiment in the Fram Strait. The UI1 mooring carried 8 hydrophones: HM501 (467m), HM502 (476m), HM504 (494m), HM505 (503m), HM506 (512m), HM507 (521m), HM509 (530m), HM310 (539m). 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 8188 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI4 mooring carried 10 hydrophones: HM531 (313m), HM532 (304m), HM533 (295m), HM534 (286m), HM535 (277m), HM536 (268m), HM537 (259m), HM538 (250m), HM539 (241m), HM340 (232). 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.
