Krill Hydroacoustic Data

 

Farallon Institute has analyzed 17 years of multi-beam acoustic data for krill in the California Current. Data comes from NOAA ship surveys extended from San Diego, California to Port Townsend, Washington.We mapped these surveys to examine the spatial distribution, densities, and persistence of krill aggregations in relation to oceanographic conditions, marine predator distributions, and bathymetric features like the continental shelf and submarine canyons. This research has important applications for conservation and marine spatial planning, particularly for designating ecologically important areas of the most productive and persistent prey aggregations in the California Current.
