Title: National marine baseline survey 1995 : littoral cell 7 : Lands End to the Severn Estuary
Author: Environment Agency
Document Type: Monograph
Abstract:
This littoral cell extends along the southern side of the Bristol Channel, from Avonmouth in the north to Cape Cornwall in the south west. There is great geographical variability within this cell with higher water quality to the south west. In contrast, the major estuarine source of the River Severn, and the high level of industry in the upper Bristol Channel have some detrimental effects on water quality. Spatial Chlorophyll-a results show that the high nutrient values recorded in the Upper Bristol Channel were not resulting in high Chlorophyll-a concentrations at the time of survey, which is probably due to the suspended solids preventing light penetration. A phytoplankton bloom was recorded close to Boscastle, Devon, during the Summer survey, which is also shown in the laboratory results.
