Dataset collected to acquire underwater sound in the Belgian Part of the North Sea (BPNS) focusing on the spatial distribution. Data were obtained by hanging a hydrophone from a rope with weights while drifting. ... : Between April 2020 and October 2020 and in June 2021, we recorded underwater sound at different strategic points of the Belgian Part of the North Sea (BPNS). All the recordings were acquired from a drifting small boat with a hydrophone attached to a rope with weights. The length of the rope was chosen according to the depth, so that the hydrophone would be in average more or less between the 1/2 and 1/3 of the top water column. The exact depth was not possible to know real-time because the plotter was turned off, so the rope length was kept constant during each entire deployment. In this manuscript, we consider a deployment the data corresponding to the time when a hydrophone is in the water without changing any recording parameter. Three different boats were used (RIB Zeekat, Sailing boat Capoeira and working boat from RV Simon Stevin). Each of these recording consists of 30 to 60 minutes of continuous recording following the current by drifting with the engines and the plotter turned off. Drifting was ...
