Ambient sound was measured in Storfjorden, Svalbard at frequencies from 30 to 24000 Hz at a depth of around 20 meters. The measurements were carried out in open sea at depths of about 100 metres or more. 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.

Oceanographic data (temperature, conductivity, pressure, currents) measured by instruments in a mooring placed next to a seafood farm in Stokksundet, Norway. The instruments collected data from 17 March to 28 April 2022 as part of a Master study. The data is presented in Røsvik (2022). Røsvik, Bjørnar Hallaråker, 2022.

CTD data file from the INTAROS2018 cruise on KV Svalbard in summer 2018.

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

Nansen Nordic Seas Database contains data from 1870-2010. This product contains oceanographic data extracted from NNSD, gridded to a 1 degree grid with monthly-mean values at [0m,5000m) depth. Variables: temperature, alkalinity, chlorophyll, nitrate, nitrite, oxygen, ph, phosphate, salinity and silicate.

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.

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.
