EurOBIS Open in mapper Explore occurrences

The data was collected under the MARBEF BIOFUSE long term monitoring program. Each participant of this program is selected 5 shores, chosen to maximise likelihood of differences in diversity (e.g. along gradient of stress - wave exposure, pollution, etc or with different recruitment regimes). Fixed sampling units randomly selected. Size of sampling Atlantic 50 x 50 cm quadrat. 5 quadrats, grid of 25 squares used to give visual estimate to nearest 5 % cover. 2 samples per year (ie every 6 months) for 2 years commencing Winter 2005-6. Taxonomic resolution: best possible resolution achievable non-destructively in the field, including macrofauna (visible to naked eye).
