Integrating Visual and Acoustic Data on Cetacean Abundance and Habitat in the Deep Water Gulf of Mexico

This page summarizes a joint effort by Scripps Institution of Oceanography and NOAA scientists to develop spatiotemporal predictions of marine mammal distributions using joint learning from visual survey and passive acoustic monitoring data.

This work was funded by the National Academy of Sciences.
