Monthly mean of absorption coefficient minus water absorption (anw) at 412nm (2002-2012) for coastal areas, at global scale, for MERIS sensor, with POLYMER atmospheric corrections. Ref: Loisel (in prep)

The update of the coastal topo-bathymetric DEM of the Pertuis charentais at a resolution of 0.0002° (~ 20 m) was carried out in the third phase of the HOMONIM project. The DEM extends from the terrestrial domain to about 60 meters depth over all the pertuis (pertuis Breton, pertuis d’Antioche and pertuis of Maumusson). The DEM is intended to be implemented in hydrodynamic models in order to produce forecasts as accurate as possible of water heights and sea states at the coast to improve the relevance of the Wave-Submergence Vigilance. This product is available with either the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical reference.

Monthly mean of diffuse attenuation coefficient (Kd) at 490nm (2002-2012), from Jamet et al (2012), for coastal areas, at global scale, for MERIS sensor, with POLYMER atmospheric corrections. Ref: Jamet et al, Retrieval of the spectral diffuse attenuation coefficient Kd(l) in open and coastal ocean waters using a neural network inversion, J. Geophys. Res., 117, C10023, doi:10.1029/2012JC008076.

The update of the coastal topo-bathymetric DEM of the Gironde estuary - downstream with a resolution of 0.0002° (~ 20 m) was carried out in the third phase of the HOMONIM project. This DEM covers the downstream part of the Gironde estuary, from Pauillac to its mouth. It is complementary to the DEM covering the upstream estuary. The DEM is intended to be implemented in hydrodynamic models in order to produce forecasts as accurate as possible of water heights and sea states at the coast to improve the relevance of the Wave-Submergence Vigilance. This product is available with either the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical reference.

Monthly mean of backscattering coefficient (bbp) at 490nm (2002-2012) for coastal areas, at global scale, for MERIS sensor, with POLYMER atmospheric corrections. Ref: Loisel in prep.

The update of the coastal topo-bathymetric DEM of the Gironde estuary - upstream with a resolution of 0.0002° (~ 20 m) was carried out in the third phase of the HOMONIM project. This DEM covers the upstream part of the Gironde estuary, from Pauillac to Bordeaux on the Garonne and to Libourne on the Dordogne. It is complementary to the DEM covering the downstream estuary (between Pauillac and the mouth of the Gironde). The DEM is intended to be implemented in hydrodynamic models in order to produce forecasts as accurate as possible of water heights and sea states at the coast to improve the relevance of the Wave-Submergence Vigilance. This product is available with either the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical reference.

World list of seaports. In its 2021 version, the repository includes 13709 ports for 187 countries. The list of seaports has been drawn up on the basis of the information available in the European reference system of places used in the framework of the Common Fisheries Policy and, more particularly, by the Electronic Recording and Reporting System (ERS), the list of ports identified by the UNECE (2021-1). An assessment of the infrastructures present along the coastline made it possible to identify other ports that were not listed. Each geographical position has been verified with Google Earth in WGS84. Each port is associated with information relating to the country (ISO 3 coding), the UNECE or ERS 5-character coding, the name, the geographical position in WGS84 (latitude and longitude), the status of the port indicating whether it is referenced by Unece (UNECE), by the EU/ERS (ERS) or by both (UNECE/ERS) In case the port is not referenced by UNECE or ERS, the status is N/A. For French ports, the reference system integrates the ports of the French overseas departments and territories with the national codification. Inland ports have also been integrated in 2021.
