The current document presents survey results and subsequent analyses yielding an abundance estimate and population trend based on data collected during June 2018. download tableDigital The National Marine Mammal Laboratory conducted aerial surveys to monitor the abundance and distribution of beluga whales in Cook Inlet, Alaska. This database contains the counts of beluga whale groups made by the aerial observers during surveys from 1993-2012, 2014, 2016, 2018, 2021 and 2022. Counts occurred concurrent with video collection during each pass near a beluga group. Aerial observer counts are used to calculate median counts for each beluga group to provide a daily index for the population prior to calculating the abundance estimate. Observer counts corrected for perception and availability bias are also used in abundance estimates when video is not available. underDevelopment Angliss, Robyn 206-526-4032 206-526-6615 7600 Sand Point Way, NE Seattle WA 98115-6349 robyn.angliss@noaa.gov pointOfContact Shelden, Kim kim.shelden@noaa.gov custodian aerial count theme Cook Inlet place DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
