The National Marine Fisheries Service (NMFS) has conducted aerial surveys to estimate the abundance of the beluga population in Cook Inlet, Alaska, between late May and early July from 1993 to 2012, after which biennial surveys began in 2014. However, the survey scheduled for 2020 was postponed until 2021 due to Covid-19, leading to consecutive surveys in 2021 and 2022. The current document presents survey data collected during late June 2021 and early June 2022, that will be used to produce an abundance estimate and population trend that will be made available in a subsequent publication. 2022 Beluga Cook Inlet Counts Survey Aerial NMFS (National Marine Fisheries Service) AFSC (Alaska Fisheries Science Center) CICOES (Cooperative Institute for Climate, Ocean and Ecosystem Studies) Submitted https://doi.org/10.25923/1wwf-2333 Public Domain 2215
