CCAMLR Antarctic Fisheries Statistical Reporting Subareas

GIS boundary and centroid data delineates CCAMLR Statistical Reporting Subareas for Antarctic marine resource management. The dataset includes line boundaries and point centroids with area name attributes, created by the Australian Antarctic Data Centre. It is no longer actively maintained as the boundaries are now available directly from CCAMLR's Online GIS.

Use Cases

• Map reported catch statistics to specific subareas using the centroid point attributes for spatial aggregation.
• Calculate adjacency and proximity between fishing zones by analyzing the boundary line geometries.
• Integrate subarea boundaries with other Antarctic GIS layers, such as bathymetry or ice cover, for habitat analysis.
• Validate reported fishing locations by checking if coordinates fall within the correct boundary polygons.

Strengths

• Provides official CCAMLR-defined spatial units for standardized fisheries reporting.
• Includes both boundary lines and centroid points with descriptive attributes.

Limitations

• Dataset is deprecated and no longer maintained by the original provider.
• The coastline of Antarctica, which forms the southern boundary, is not included in the data.
• Specific metadata like row count, file format, and license are unknown.
