<p>The two SOMLIT-Wimereux time-series data characterize hydrology and plankton biomass and diversity of the eastern English Channel near Boulogne sur mer, located at 50°40,75'N and 1°31,17'E and 1° 24,64'E . Fortnightly measurements have been undertaken since 1998 by a laboratory involving the CNRS, University of Lille and ULCO, named the Laboratory of Oceanology and Geoscience (UMR 8187 LOG) since 2008 (https://log.cnrs.fr). The SOMLIT-Wimereux observation station is a part of the French monitoring network SOMLIT (https://www.somlit.fr/), accredited by the CNRS as a national Earth Science Observatory (Service National d’Observation : SNO).-nbsp;</p>

French benthic invertebrates composition and abundance taxa data are collected during REBENT monitoring surveys on the English Channel / Bay of Biscay coasts and during RSLFAU monitoring surveys on Mediterranean coast. Protocols are implemented in the Water Framework Directive.

Data comprised a regular grid extending into the English Channel, including UK waters. In total, 15 stations were sampled for macrobenthos.

This dataset contains macrobenthos data from the French Sector of the North Sea from 2000. Dataset in the framework of the North Sea Benthos Project, which integrated recent (1999–2002) macrobenthic infaunal and environmental data from various national sources.

North Sea macrobenthos species density and abundance, measured on a regular grid of stations corresponding with ICES standard stations. All sampling was done in spring 1986.
