This API provides geospatial data from the CAREMaërl project mapping maërl and rhodolith habitats in the Port-Cros National Park sector, part of action D1 of the Life Marha project on the French Mediterranean coast. The work aims to map these habitats down to the 60-metre isobath to inventory their distribution, and to assess their health status through hyperbaric diving surveys, photo-identification and species determination. A towed video system with five cameras enabled live viewing, annotation and geolocated recording along transects between the lower limit of posidonia meadows and -60 metres. Data follow the National Typology of Mediterranean Benthic Biocenosis (NatHab-Med) and the OFB HABITAT layer model. Published via Etalab.Cartography of movable funds is of habitats in rhodoliths resulting from the CAREMaërl project in the sector "National Park of Port-Cros" carried out within the framework of the action D1 of the project Life Marha. The objective of this project is twofold: - Mapping the habitats at maërl and rhodoliths on the Mediterranean coast to the isobath 60 metres deep, in order to make it possible to establish an inventory of the distribution of these habitats; - Evaluate the health status of these habitats on sectors in the Mediterranean through a protocol carried out in hyperbaric diving, by photo identification and determination of the species associated with the different study sectors. The towed video system (5 cameras) allowed the live viewing and annotation in the cabin of an oceanographic vessel and a geolocated recording of all observations made during the campaign on transects regularly spaced between the lower limit of the posidonia herbarium (around -25 m in the southern region) and the isobath of -60 meters. The typology used for this project is the "National Typology of Mediterranean Benthic Biocenosis (NatHab-Med)". The attribute table follows the HABITAT layer model of the OFB.

Data access
This API doesn't publish a machine-readable schema (such as an OpenAPI spec) that we can read automatically, so there's no field list to show here. See the documentation for its available endpoints and response formats.
