Subset of acoustic data with AIS labels deployment from Grafton station in the Belgian Part of the North Sea, recorded in fall 2022

The dataset includes underwater acoustic data and vessel labels derived from AIS (Automatic Identification System) information from AISHub. Recordings were made at Grafton Station (51.40666°N, 2.819°E) in the Belgian part of the North Sea using RESEA 320 recorders (RTSys, France) together with Colmar GP1190M-LP hydrophones (Colmar, Italy, sensitivity: -180 dB/V re 1μPa, frequency range −3 dB: 10 Hz to 170 kHz), attached to steel mooring frames at 1 m above the sea bottom, with no moving parts. Duty cycle was set to 24h on, 24h off, leading to five non-consecutive recordings days: October 28, October 30, November 1, November 3, and November 5, 2022.  These data enable analysis of marine acoustic environments in relation to nearby ship traffic.
