Seabird Population Density in German Offshore Areas on a 10x10 km Grid

Population density data for the Horned Grebe (Podiceps auritus) in German offshore areas, modeled on a 10x10 km EU-GRID. The data are based on seabird surveys conducted as part of the BfN monitoring programme, with density calculated per grid cell from individual counts and survey effort. Single layers show the distribution of individual seabirds divided by season, as referenced in the 2007 publication by Garthe et al.

Use Cases

• Modeling seasonal distribution patterns of the Horned Grebe based on the gridded density data.
• Assessing biogeographic importance of seabird populations in the German North Sea based on the referenced methodology.
• Analyzing population density trends from monitoring programme surveys.
• Integrating species-specific seasonal layers into broader marine spatial planning.

Strengths

• Data is based on a formal monitoring programme (BfN).
• Density is calculated per standardized 10x10 km grid cell (EU-GRID).
• Seasonal distribution layers are provided, following a peer-reviewed methodology.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
