Little is known about the ecology of many beaked whale species, despite 
concerns raised by mass strandings linked to certain sources of anthropogenic 
noise. Here, we used passive acoustic monitoring to examine spatial and 
temporal patterns in beaked whale occurrence at six locations along the 
continental slope in the western North Atlantic Ocean. We analyzed 2642 days of 
recordings collected between 2011 and 2015, and identified echolocation signals 
from northern bottlenose whales (Hyperoodon ampullatus), Cuvier’s (Ziphius 
cavirostris), Sowerby’s (Mesoplodon bidens), Gervais’, (Mesoplodon europaeus), 
and Blainville’s (Mesoplodon densirostris) beaked whales, and one signal type 
of unknown origin. We recorded multiple species at each site, with detections 
generally occurring year-round, and observed latitudinal gradients and 
site-specific variation in relative species occurrence. Notably, we regularly 
detected Cuvier’s beaked whales in a region where they have not been commonly 
observed, and discovered potential habitat partitioning among Cuvier’s and 
Gervais’ beaked whales within their overlapping ranges. This information on the 
distribution and seasonal occurrence of North Atlantic beaked whale species 
offers new insight into patterns of habitat use, and provides a year-round 
baseline from which to assess potential anthropogenic impacts.
