The Dogger Bank, a shallow sandbank in the center of the North Sea, has a valuable status as a Special Area of Conservation (SAC) and an Important Marine Mammal Area (IMMA). However, the region faces increasing amounts of anthropogenic activity and the produced underwater noise may affect sound-sensitive species, such as the harbor porpoise. This study presents findings from a short-term passive acoustic monitoring campaign (July–November 2024) conducted in the northwest corner of the Dogger Bank, addressing the previous lack of sound data available in this remote region. Daily median sound pressure levels ranged between 97 and 109 dB re 1 μPa, with ship passages and geophysical survey sounds causing transient spikes in sound pressure levels below 1 kHz. Natural drivers of variability were also examined, revealing a positive correlation between wind speed and sound levels above 800 Hz. In terms of biological detections, 23% of recordings contained high-frequency clicks classified as harbor porpoise. Fish and minke whale vocalizations were also manually identified. The data recorded provided new insights into the soundscape of this internationally recognized marine mammal habitat, the first step in understanding how anthropogenic activity may alter sound levels from baseline and the degree of mitigation required.
