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).

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. 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).

Tara expeditions sampled the world’s oceans with standardized protocols, putting an exceptional effort into sampling plankton diversity across a large size range, using a combination of water samples and net tows. The efforts to explore the genomic diversity of plankton, through metabarcoding and metagenomics, have led to well publicized papers and have made the renown of Tara. While a similar extensive effort has been put on imaging, the datasets are not public yet. In a limited number of stations, in addition to the usual 5μm -> ~5cm Tara sampling strategy, Bongo net samples were taken during the day and during the night, at the same station; this is the content of this dataset. Using a 300µm mesh net, it cover organisms from 300µm to ~3cm

Tara expeditions (2009-2013) sampled the world’s oceans with standardized protocols, putting an exceptional effort into sampling plankton diversity across a large size range, using a combination of water samples and net tows.

While a similar extensive effort has been put on imaging, the datasets are not public yet. In a limited number of stations, in addition to the usual 5μm -> ~5cm Tara sampling strategy, multinet trawls allowed to sample the vertical distribution of plankton; this is the content of this dataset. Using a 300µm mesh net, it cover organisms from 300µm to ~3cm.

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.

The Tara Oceans project sampled contrasting ecosystems of the world oceans during a three-year expedition (2009-2013), collecting environmental data and plankton, from viruses to metazoans, on board the 36-metre Tara Schooner. It surveyed 210 ecosystems in 20 biogeographic provinces, collecting over 35,000 samples of seawater and plankton. Samples were later analysed using modern sequencing and state-of-the-art imaging technologies.

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.
