Sea Lion tracks (1)
Eonfusion was used to determine which components of fish stocks are successfully and unsuccessfully caught by juvenile Steller sea lions. Individual sea lions were tracked from a research vessel using VHF transmitters. Concurrent vessel-based hydro-acoustic surveys of fish stocks provided data on prey distribution and abundance in the areas used by the sea lions. Sea lion diving behavior was examined using time-depth recorders.
Using Eonfusion, individual sea lion tracking data was fused to depth information from the time-depth recorders. Hydroacoustic prey data was processed using Echoview to classify fish stocks at depth, and the output was incorporated into the dataflow. Bathymetry and satellite imagery were integrated to create a multi dimensional image of predator and prey habitat.
