Cartographie des habitats benthiques du secteur des Gl├®nan (REBENT, 2006)
Description
This comprehensive map of the benthic communities of Les Gl├®nan is realized as part of the REBENT programme, i.e. the surveying network for the benthic fauna and flora. It is the result of the treatment, the analysis and the data aggregation from authors and multiple specialized agencies :
- ORTHOLITTORALE 2000,
- IFREMER, Lidar altimetry in 2005,
- M. Le Hir, S. Chauvaud, G. Robert, from the engineering firm " T├®l├®d├®tection et Biologie Marine " (TBM) in 2005,
- N. Alloncle, student at the Brest University in 2005,
- CEVA in 2004 and 2005,
- Bathymetric data from SHOM,
- Rebent intertidal and subtidal field studies data collected between 2003 and 2006.
For these studies, various methods were used : coastal orthophotography, altimetric data from LIDAR, acoustic techniques, benthic sampling techniques, intertidal surveys.
The habitat typology held for the cartography is the EUNIS classification, the European reference (October, 2004 version).
In the rocky sectors, groupings of EUNIS classes were realized when the EUNIS typology was difficult to apply. It allows describing more easily the various environments.
The original legend is transferred to the "ORIG_HAB" attribute data field.
The harmonization with the EUNIS typology was made in 2006, as part of the REBENT and Interreg-MESH programmes.
