| Estuaries are crucial ecosystems where human activities deeply affect numerous ecological functions. Here we present a survey dataset based on the monitoring of fish nursery grounds of the Seine estuary and eastern bay of Seine collected once a year using a beam trawl during three distinct periods (1995-2002, 2008–2010 and 2017–2019). The surveys happen at the start of autumn in order to maximize the catchability of juvenile fish. The beam trawl mainly targets benthic and demersal species on a study area that extends over 600 square kilometers. The dataset includes abundance and densities of 161 species for 634 hauls performed around 40 stations each year. These data can be used by fishery scientists and ecologists motivated by early life stages of... |

| The consistency of satellite and in situ time series of Chlorophyll-a (Chl-a), Turbidity and Total Suspended Matters (TSM) was investigated at 17 coastal stations throughout the year 2017. These stations covered different water types, from relatively clear waters in the Mediterranean Sea to moderately turbid regions in the Bay of Biscay and the southern bight of the North-Sea. Satellite retrievals were derived from MODIS/AQUA, VIIRS/NPP and OLCI-A/Sentinel-3 spectral reflectance. In situ data were obtained from the coastal phytoplankton networks SOMLIT (CNRS), REPHY (Ifremer) and associated networks. Satellite and in situ retrievals of the year 2017 were compared to the historical seasonal cycles and percentiles, 10 and 90, observed in situ. Regarding the... |

| L’estuaire de Seine est un habitat essentiel pour les espèces halieutiques emblématiques de la façade Manche-Mer du Nord en sa qualité de nourricerie. Cet estuaire a connu de profondes modifications morphologiques au cours des 30 dernières années des suites d’une forte anthropisation de ces rives. Cet habitat estuarien-côtier, comptant parmi les habitats les plus productifs du milieu marin, joue un rôle central dans le renouvellement des stocks de pêche, en favorisant la croissance et la survie des juvéniles des espèces dites « nourricerie-dépendantes ». Malgré une couverture temporelle très inégale dans les campagnes depuis 30 ans, les suivis des communautés de juvéniles et les observations biotiques (communautés benthiques), abiotiques (hydrodynamisme,... |
