[MARMAM] Request for information - depth preferences of cetaceans

Dear MARMAM-ers

We are investigating how likely cetacean species are to encounter underwater anthropogenic noise (from shipping and seismic surveying for example) using noise propagation models. The likelihood of cetaceans encountering adverse levels of noise will vary with depth, as sound propagation is dependent on factors such as seawater temperature, salinity, and density. We therefore need to assign cetacean species to rough depth strata (0-100m, 0-500m, 0-1000m, and 0-2000m). Does anybody have information on the dive range or depth preferences for cetacean species occurring in the Northeast Atlantic?
