Description

Opportunistic macroalgae blooms (green tides) data are collected during monitoring surveys on the English Channel / Bay of Biscay French coasts since 2008 (Quadrige program code : BLOOMS). Protocols are implemented in the European Water Framework Directive.

Parameters

Area of sample {sampled area} from the bed [BODC]
Areal extent of Ulva (ITIS: 6559: WoRMS 144296) Morphology: blade Subgroup: bloom on the Earth by aerial photography, GIS analysis [BODC]
Areal extent of Ulva (ITIS: 6559: WoRMS 144296) Morphology: blade+filamentous Subgroup: bloom on the Earth by aerial photography, GIS analysis [BODC]
Coverage (as an area) of Ulva (ITIS: 6559: WoRMS 144296) Morphology: blade on the Earth by aerial photography, GIS analysis and computation from areal extent multiplied by coverage ratio [BODC]
