A.2019Scientific Reports9, 12617https://doi.org/10.1038/s41598-019-49115-y During the eastern North Pacific gray whale 2014–2015 southbound migration, acoustic call recordings, infrared blow detections, and visual sightings were combined to estimate cue rates, needed to convert detections into abundance. The gray whale M3 acoustic call rate was 2.3–24 calls/whale/day with an average of 7.5 calls/whale/day over the entire migration (southbound and northbound) and showed a positive trend from 30 December–13 February. The infrared camera blow rate averaged 49 blows/whale/hour over 5–8 January. With a call rate model, we estimated that 4,340 gray whales migrated south before visual observations began on 30 December, which is 2,829 more gray whales than used in the visual abundance estimate. This finding highlights the usefulness of cue rates to increase precision in abundance estimates. We suggest that visual observers increase their survey effort to all of December to verify gray whale abundance corrections. Probability of detection of a whale blow by the infrared camera was the same at night as during the day. However, probability of detection decreased beyond 2.1 km offshore, whereas visual sightings revealed consistent whale densities up to 3 km offshore. We suggest that future infrared camera surveys use multiple cameras optimized for different ranges offshore.Please contact data providerInfrared camera located at 36 26' 24.61" N 121 55'19.41"W "Effort" tab gives the start and end times of each infrared video in Julian Date, Matlab datenum format: Days since Jan 0, 0000.
