Sea ice macrofauna comprises invertebrates (>2 mm) that live associated with or in sea ice.

The dataset contains records of presence and absences and abundance data on sea ice macrofauna from the entire Arctic.

The source of the data is published literature (peer-reviewed articles, public databases, grey literature) as well as unpublished records.

For each record the data source, sample date, sample position and environmental background data (as far as available) is provided. The database includes data sampled between 1947-2012.

This database is the product of a joined effort of the Sea Ice Expert Network within the Circumpolar Biodiversity Monitoring Program.
