Abstract/Summary

Results are reported for the analysis of water samples taken from the L4 long-term sampling station (50°15'N; 4°13.02'W) situated off Plymouth on the south-west coast of England, United Kingdom. The analyses are reported for Nitrate+Nitrite, Nitrite, Silicate and Phosphate concentrations. The dataset begins in 2000 and runs through till end of 2021, and the data is an ongoing time series. In the early years the samples were taken and frozen to be batch analysed at a later date. Since 2007 the site visits have been on a more regular weekly sampling protocol and there are at times both filtered and unfiltered sample results. In 2021 the RV Plymouth Quest had an engine failure and was out of action for a number of months, and the sampling was then carried out by the MBA Sepia research vessel. A classical picture is seen of generally summer nutrient depletion and with higher winter concentrations of Nitrate, Silicate and Phosphate.
