St. Lawrence Estuary seasonal distribution data for the beluga whale population (Delphinapterus leucas). The dataset represents three groups: females with calf, adult males, and mixed sectors, based on published data from Fisheries and Oceans Canada. Herd distribution areas are only valid during the summer, and specific herd uses of these areas are unknown.
Use Cases
- Mapping summer habitat zones for beluga whale groups based on herd distribution areas.
- Analyzing spatial separation between females with calves, adult males, and mixed groups based on the three represented categories.
- Studying seasonal marine mammal distribution patterns based on summer-only validity of the data.
Strengths
- Data is sourced from a published technical report by Fisheries and Oceans Canada.
- Distribution is categorized for three distinct demographic groups.
- Available in multiple geospatial formats including SHP, CSV, and ESRI REST.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data validity is restricted to the summer season, and herd uses of areas are unknown.
