XBT profiles of temperature and pressure, and XCTD profiles of temperature, salinity, and pressure, collected in the Fram Strait from KV Svalbard in July 2016. The data collection also include calculated sound speed profiles provided by the instrument manufacturer. There are a total of 150 profiles and 366117 observations.

Time averaged sound pressure obtained from the ACOBAR acoustic experiment in Fram Strait. The data were were obtained over 362 days every 3 hours from Aug 2010 - Jul 2011, and over 311 days every 3 hours from Sep 2011 - Jul 2012. 10-, 50- and 90- percentiles of the sound pressure and power for each frequency (0-500 Hz) were computed.

XBT profiles of temperature, pressure and sound speed in the Fram Strait from KV Svalbard in September 2011. There are a total of 45 profiles and 114176 observations. The XBT probe T5 was used, see http://www.sippican.com/contentmgr/showdetails.php/id/312 for more info on the probe.

CTD data collected in Bjørnafjorden and Langenuen, Norway, during a cruise with KV Tor.

Three GPS trackers were deployed on sea ice in the Fram Strait between 7th and 8th July 2016, collecting GPS data until 10th September 2016 with an interval between 5 and 30 min.

XBT profiles of temperature, pressure and sound speed in the Fram Strait from KV Svalbard in September 2012. There are a total of 7 profiles and 11365 observations. The XBT probe T5 was used, see http://www.sippican.com/contentmgr/showdetails.php/id/312 for more info on the probe.

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.
