Title: National marine baseline survey 1995 : littoral cell 6 : Portland Bill to Lands End
Author: Environment Agency - National Centre for Environmental Data and Surveillance
Document Type: Monograph
This report describes the National marine baseline of the English Channel coast stretches from Portland Bill to Lands End. This littoral cell extends from Portland Bill to Lands End. Water quality in the region is high, with little industrialisation. There is a general increase in quality with lower concentrations of determinands towards the west which marks the influence of open ocean water from the Atlantic. Nutrient concentrations during Summer are higher than average, with the highest levels being found to the west of the cell. This may be due to rainfall runoff across agricultural land, or a results of the increased population during the tourist season. The fluorimeter data recorded a number of blooms in this area which are potentially caused by the nutrients. Copper concentrations are also high in comparison to other dissolved metals results. This is probably due to rainfall runoff across old copper workings, particularly in Cornwall.
