Marine database – marine biodiversity and biogeochemistry

Norwegian Polar Institute's [marine database](https://doi.org/10.21334/marine-db) is organised in the following collections that contain results or metadata from seawater and sea-ice sampling: * Darwin Core Occurrence records (quantities of an organism relative to a standard volume or area) * Darwin Core Sampling Event metadata * Biogeochemistry data The occurrence (aka. abundance) data is split in the following sub-collections: * [Marine protist biodiversity](https://data.npolar.no/dataset/322b6bdd-1326-4e70-9d77-a8cd861db8ec) `cells/l` * [Marine zooplankton and icefauna biodiversity](https://data.npolar.no/dataset/9167dae8-cab2-45b3-9cea-ad69541b0448) `ind/m3` or `ind/m2` * Darwin Core Taxon database
