Beluga Whale Sightings in Beaufort Sea and Amundsen Gulf, July 1992

Aerial survey data from July 24-25, 1992, documents beluga whale locations in the Beaufort Sea and Amundsen Gulf. The dataset, published in a 1996 Canadian Data Report, provides geospatial information on marine mammal observations. Specific row and column counts are not provided.

Use Cases

• Map beluga whale sighting locations from the aerial survey to analyze spatial distribution in the Beaufort Sea.
• Analyze geospatial data to correlate beluga whale presence with specific marine areas documented in the 1992 survey.
• Use the tabular data format to study beluga whale group sizes or behaviors reported during the two-day observation period.

Strengths

• Data originates from a peer-reviewed Canadian Data Report of Fisheries and Aquatic Sciences (No. 964).
• Provides specific temporal coverage for a focused two-day aerial survey period in July 1992.
• Covers a defined geographic area: the southeast Beaufort Sea, Mackenzie River estuary, and west Amundsen Gulf.

Limitations

• The dataset is temporally limited, containing only observations from two specific days in 1992.
• Unknown sample size and feature set, as row and column counts are not specified.
• Primary data collection occurred over 30 years ago, which may limit relevance for current population studies.
