Specification of the desirable and recommended product attributes for generating spatial layers of sea-level trend (units: mm/year) from tide gauges over periods of 50 years (1963-2012) and 100 years (1913-2012), to characterize and assess average annual sea-level rise at the coast.

Specification of the desirable and recomended product attributes for generating spatial layers of sea surface temperature temperature trend for the last 10, 50, 100 years for the Mediterranean basin and for each NUTS3 region along the coast.

This gridded product visualizes 1960 - 2014 water body chlorophyll-a (mg/m^3) in the North Sea domain, for each season (winter: December – February; spring: March – May; summer: June – August; autumn: September – November). It is produced as a Diva 4D analysis, version 4.6.11: a reference field of all seasonal data between 1960-2014 was used; results were logit transformed to avoid negative/underestimated values in the interpolated results; error threshold masks L1 (0.3) and L2 (0.5) are included as well as the unmasked field. Every step of the time dimension corresponds to a 10-year moving average for each season. The depth dimension allows visualizing the gridded field at various depths.

Climatology done from the SeaDataNet aggregated dataset v1.1 for the North Atlantic Ocean. The version used for the DIVA software is the 4.6.9. The period covers 1900-2013. For data access please register at http://www.marine-id.org

Description of attributes for time series of annual average sea level (units: mm) from tide gauges over periods of 50 years (1963-2012) and 100 years (1913-2012), to characterize and assess average annual sea-level rise relative to the land.

The Sir Alister Hardy Foundation for Ocean Science (SAHFOS) is an international charity that operates the Continuous Plankton Recorder (CPR) Survey. The dataset covers the North Atlantic and the North Sea on since 1958.

Avec près de 1,4 millions d’hectares de surface agricole utilisée et 100 000 ha d'estives, l'agriculture occupe en 2010 près de 35 % du territoire aquitain. Par son assolement diversifié, elle contribue largement à la diversité des paysages et la structuration de l'espace régional. Toutefois, au cours de la dernière décennie, plus de 96 000 hectares ont quitté le giron de l'agriculture...

Les périmètres des quartiers prioritaires de la politique de la ville sont fixés par le décret n° 2014-1750 du 30 décembre 2014 pour la métropole et par le décret n° 2014-1751 du 30 décembre 2014 pour les départements et collectivités d’outre-mer, rectifiés par le décret n°2015-1138 du 14 septembre 2015.

This gridded product visualizes 1960 - 2014 water body total phosphorus concentration (umol/l) in the North Sea domain, for each season (winter: December – February; spring: March – May; summer: June – August; autumn: September – November). It is produced as a Diva 4D analysis, version 4.6.11: a reference field of all seasonal data between 1960-2014 was used; results were logit transformed to avoid negative/underestimated values in the interpolated results; error threshold masks L1 (0.3) and L2 (0.5) are included as well as the unmasked field.
