Full Citation Examples
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.

| Abstract: |
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. |
| Purpose: |
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. |

| Description: |
The National Marine Fisheries Service (NMFS) has conducted aerial surveys to estimate abundance of the beluga population in Cook Inlet, Alaska, each June, July, or both from 1993 to 2012, after which biennial surveys began in 2014. The current document presents survey results and subsequent analyses yielding an abundance estimate and population trend based on data collected during June 2018. |
Data Quality
| Quality Control Procedures Employed: |
After each survey day, data were quality controlled by checking all hand entered information from that day including weather, sightings, species, group sizes, observer position, and comment data for errors. |
