 2017.  Long-term passive acoustic recordings track the changing
distribution of North Atlantic right whales (*Eubalaena glacialis*) from
2004 to 2014. Scientific Reports 7: 13460. DOI:10.1038/s41598-017-13359-3


Given new distribution patterns of the endangered North Atlantic right
whale (NARW; *Eubalaena glacialis*) population in recent years, an improved
understanding of spatio-temporal movements are imperative for the
conservation of this species. While so far visual data have provided most
information on NARW movements, passive acoustic monitoring (PAM) was used
in this study in order to better capture year-round NARW presence. This
project used PAM data from 2004 to 2014 collected by 19 organizations
throughout the western North Atlantic Ocean. Overall, data from 324
recorders (35,600 days) were processed and analyzed using a classification
and detection system. Results highlight almost year-round habitat use of
the western North Atlantic Ocean, with a decrease in detections in waters
off Cape Hatteras, North Carolina in summer and fall. Data collected post
2010 showed an increased NARW presence in the mid-Atlantic region and a
simultaneous decrease in the northern Gulf of Maine. In addition, NARWs
were widely distributed across most regions throughout winter months. This
study demonstrates that a large-scale analysis of PAM data provides
significant value to understanding and tracking shifts in large whale
movements over long time scales.
