This dataset gathers the names of 86 species of fish as well as their trophic category, abundance and biomass per replicate, sampled by bottom trawling in Posidonia oceanica beds in three main geographic areas (Marseille, Port-Cros Island and Galeria in Corsica) of the Mediterranean French coast. Samples were collected by bottom trawling performed in seagrass meadows between 10 and 40 m depth at different seasons (summer-winter) and period (day-night) at several occasions between 1980 and 2013. This dataset is a witness of the structure, functioning and evolution of fish assemblages in north-western Mediterranean Posidonia oceanica beds.   Image Reference: https://www.seanoe.org/data/00907/101934/illustrations/illustration-236.gif.   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

The MOOSE-GE cruises aim to provide an annual summer snapshot of the North-Western Mediterranean Sea basin, to observe changes in water mass properties, biogeochemical content and changes in planktonic biodiversity (https://doi.org/10.18142/235). These cruises are part of the national MOOSE program (Mediterranean Ocean Observing System for the Environment) funded by CNRS-INSU and the Research Infrastructure ILICO (French Ministry). Since 2012, lowered and ship ADCP data were collected during MOOSE-GE cruises. This data set contains quality controlled data of horizontal currents measured by ship and lowered ADCPs.
