Western Channel Observatory (E1) nutrient concentration profiles (2002 - 2017)

Abstract

Link to the related European Directory of Marine Environmental Data (EDMED) record Results are reported for the analysis of water samples taken from the E1 longterm sampling station (50 02.0' N;04 22.0 'W) situated off the southwest coast of England, United Kingdom. Data consists of results for samples that are both filtered and unfiltered. The analyses are reported for Nitrate+Nitrite, Nitrite, Silicate and Phosphate concentrations. The dataset begins in 2002 and runs through till 2017, though the data is an ongoing time series. Since 2007 the site visits have been on a more regular almost fortnightly sampling protocol, however due to the more 'offshore' nature of the site there are many sampling weeks lost due to bad weather. A classical picture is seen of generally summer nutrient depletion and with higher winter concentrations of Nitrate, Silicate and Phosphate. Temporal coverage 26 June 2002 - 19 December 201
