Nutrient concentration profiles from long term time series at Station E1 in the Western English Channel from 2002 to 2015.

Results are reported for the analysis of water samples taken from the E1 long-term sampling station (50 02.0' N; 04 22.0' W) situated off the south-west coast of England, United Kingdom. Data consists of results for samples that are both filtered by 0.2 um filter, and unfiltered. The analyses are reported for Nitrate+Nitrite, Nitrite, Silicate and Phosphate concentrations. The dataset begins in 2002 and runs through till 2015, 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.
