92 CalCOFI stations sampled, sized by observations, over the survey grid.

Overview

Hourly presence of blue, fin and humpback whale calls in sonobuoy recordings from CalCOFI cruises, 2004-2012. Each record is one hour of a DIFAR or omnidirectional sonobuoy deployment near a CalCOFI station, scanned by an analyst as 60-second spectrogram windows, with the call types heard. Curated by the Scripps Whale Acoustics Lab (Baumann-Pickering) and staged from the CalCOFI marine mammal Shiny app repository (CalCOFI/marmam-app). The hydrophone depth is not recorded (the DIFAR or omnidirectional setting is not given), so sample and observation depths are empty, not 0 m. Hours scanned only for a few calls (“adhoc only”) are kept as samples with no presence value.
