The monitoring at station SOMLIT-Astan (north of Roscoff - France, Western English Channel) was designed to study long term changes in phytoplankton communities in a global change context (diversity, phenology).

Data obtained by Alain Sournia as part of a monitoring program : abundances of diatoms, abondances of cells of the genus <i>Guinardia</i> (measured bimonthly)

Samples and data obtained by the "Plankton group"- Abundances of phytoplankton taxa, some samples still to be processed (samples taken bimonthly, samples 2000 to 2003 and 2007-2008 treated)

Data obtained by the "Plankton group" - abundances of picoplanktonic cyanobacteria, cryptophytes, eukaryotes and bacteria (measured monthly)

Data obtained by the "plankton group" as part both of research programs and monitoring programs. Parameters measured are : Abundances of picoplanktonic cyanobacteria, cryptophytes, eukaryotes and bacteria (measured bimonthly)

These inventories list marine species observations performed in the Roscoff area since 1830. Observations result from a review of historical literature and observations made by voluntary contributors and the scientific teams of the Roscoff Marine Station. Taxonomic groups documented in the inventories are macroalgae, marine benthic macroinvertebrates and fish. Inventories provide information (when known) about: location, collection date, collection type, collector, and species biology (habitat, reproduction period).

Monitoring of species richness, abundances of all macrobenthic species, biomass, sediment grain size, temperature and salinity

Monitoring of species richness, abundances of all macrobenthic species, biomass, sediment grain size, temperature and salinity. The experiment was designed to study long-term changes in community structure in response to global change (climatic change) and local anthropogenis pressures (e.g. eutrophication).

The monitoring at the Château du Taureau station (north Brittany - France, Western English Channel) was designed to study the influence of trophic conditions on larval development of the invasive species Crepidula fornicata.
