UNDER-ICE: A dataset of underwater passive acoustic recordings from a 2-year mooring deployment in Fram Strait
Sammendrag
Abstract: The UNDER-ICE acoustic thermometry experiment deployed 5 moorings in Fram Strait from 2014-2016. The mooring locations cover the central Fram Strait between 78° and 80° N and contain both mooring locations which are covered by sea ice most of the year and ice-free mooring locations. Each mooring consisted of a DSTAR control unit and of 10 hydrophones modules in an array configuration with a vertical distance of 9 m between hydrophones. The hydrophone module depth varied between moorings, with the shallowest hydrophone at 232 m depth and the deepest hydrophone at 574 m. The recordings occur every 3 hours and are each 130 seconds long. Acoustic recordings from long deep-water moorings differ from bottom-mounted hydrophones as they can be influenced by noise from the mooring itself due to cable strumming in strong currents. An extensive quality control was there conducted with the data set. The fact that cable strumming correlates with strong currents and mooring pulldowns could be used to identify recordings that are potentially influenced by cable strumming. Quality flags denote which recordings are likely to be influenced by noise from cable strumming. Level 1 data from the experiment are published as netcdf files containing noise level percentiles as a function of frequency. The netcdf files also contain all necessary metadata about the experiment.
