Beaked whales are known to be the deepest diving marine mammal, but because their elusive, deep-water diving behavior, distribution and abundance are not well understood.  Beaked whales produce echolocation clicks sound unique to each species.

Oregon State University has conducted performance evaluation tests of acoustic gliders and profiler floats for detection of beaked whale sounds. We have installed the WISPR board, a passive acoustic monitoring (PAM) device available from EOS on the Seaglider (Kongsberg) and APEX profiling float (Teledyne Webb).

This blog aims to serve as a resource of information about these systems, our experiments, and as an archive of example data files.

Short example data files are available for DCLDE algorithm development here. Additional files are available by request. Also data files from HARP (High-Frequency Acoustic Recording Packages) from Scripps and DASBR (Southwest Fisheries Science Center, NOAA) are available.
