If AUV survey design does not consider the practical limits to change detection and include best practices to minimize noise, however, the results may be ambiguous or even useless. Using a series of simulations combining real bathymetric digital...

... with limited dependency on sea state. At the same time, wind turbine manufacturers are developing larger offshore wind turbines and legislators are instituting more limitations, for example on the emissions of underwater noise. These developments create additional challenges for upscaling the installation...

... at the time. At frequencies of 1Hz and below there is a nearly continuous background noise coming primarily from the South and East that rumbles along for the entire 2.5 hours, with a phase velocity across the array of about 2000 m/s. This is most likely ocean wave-generated noise. At frequencies below 2Hz...
