TROPHOS: Temporal patterns for meiobenthos species at stations 115bis and 330 in the Belgian Part of the North Sea (2002-2003) [Temporele patronen voor meiobenthos soorten in stations 115bis en 330 in het Belgisch deel van de Noordzee (2002-2003)] Citation See unpublished Maria Franco. https://marineinfo.org/id/dataset/55 Availability: Unrestricted after moratorium period Data are initially restricted, but the access condition relaxes to academic or unrestricted once a specified period of time after an event (such as collection, publication, completion of QC procedures or project cessation) has elapsed Description This dataset contains data on two stations on the Belgian Continental Shelf that are sampled monthly for meiobenthic organisms and environmental variables. more The aim of the study is to relate functional and structural diversity of nematode communities from contrasting sediments with the food availability.
