This IGA-HP Gravelines dataset includes long-term time series on marine phytoplankton, zooplankton, and hydrological data from 1978 onward at the coastal station named “canal d’Amenée” (in French) near the Gravelines Nuclear Power Plant located in the southern bight of the North Sea, near the Dover Strait (eastern English Channel). Phytoplankton data essentially cover microscopic taxonomic identifications and counts (cells.l^-1), and pigment concentrations (Chlorophyll-a and pheopigment) (µg.l^-1). Zooplankton data cover binocular microscope taxonomic identifications and counts (nb.m^-3). Hydrological data include temperature (°C), salinity (PSU), turbidity (NTU), dissolved oxygen concentration (mg.l^-1), and dissolved inorganic nutrient concentrations (ammonium, nitrite + nitrate, phosphate, silicate) (µmol.l^-1).

Utilisation

Data are published without any warranty, express or implied. The user assumes all risk arising from his/her use of data. Data are intended to be research-quality and include estimates of data quality and accuracy, but it is possible that these estimates or the data themselves contain errors. It is the sole responsibility of the user to assess if the data are appropriate for his/her use, and to interpret the data, data quality, and data accuracy accordingly. Authors welcome users to ask questions and report problems.

Acknowledgements

The acquisition of this dataset was performed in the framework of the IGA network, conducted by Ifremer with the financial support from EDF (Électricité de France) since 1978. Acquisition of such long term database is also the result of long term efforts done by the national managers of the IGA program, the coordinators of the Gravelines Nuclear Power Plant, and all the technical teams and subcontractors who have been involved in sampling and analysing the various compartments followed within the frame of the monitoring program since 1978. Finally, acknowledgment to EDF for providing the scientific community access to the data.
