basin_size

character Size of sampled site (e.g. lake, bog, etc.) in [km^2] or given as a categorical estimated when precise information was not recorded or was not available

site_type

character Information about type of site (e.g. cave, lake, glacial, terrestrial, etc.)

entity_type

character Information about the type of entity (e.g. composite, core top, surface sample, etc.)
