  • This dataset includes catchment stream inflow and outflow rates, secchi depth, chlorophyll, phytoplankton counts and nutrient concentrations for the lake, inflow, outflow and groundwater spring. The measurements are from a PhD research project at Rostherne Mere in Cheshire. These data were collected to show the relationship between the catchment hydrology and in-lake nutrient loads for assessment of the current catchment nutrient budget. The monitoring study covered a period from January 2016 to January 2017. All data is presented with date, flow rate, nutrient and chlorophyll concentrations and phytoplankton species abundance. The work was carried out as part of a Natural Environment Research Council (NERC) funded PhD [grant number NE/L002493/1]. Full details about this dataset can be found at

  • Water samples were collected for chlorophyll and nutrient concentrations, biogenic and lithogenic silica concentrations, particulate organic carbon and nitrogen (POC/PON) concentrations, phytoplankton identification, Si, C, N, and Ge isotopes, particulate Ba, and other trace elements associated with suspended particles. Some samples were collected by small boat launched from Rothera research station and other seawater samples were collected from under the ice by divers. Water was also collected from RaTs (Rothera Oceanographic and Biological Time Series) CTD sites 1 and 2, and from Honeybucket (off Rothera Point). Brine was collected by drilling a hole, washing out and waiting for the hole to fill (sack-hole drilling). Blocks of ice were also collected and stored at -80 degrees C before being thawed for analysis. The sea-ice and brine was analysed for trace metals (Al, Zn, Cd and Co) for 5 different collection dates in 2004/2005.

  • This dataset consists of phyto- and zooplankton counts, chlorophyll concentration and fish catch data from the Cumbrian Lakes (Blelham Tarn, Esthwaite Water, Windermere north and south basins). The data span the years 1940 to 2013 but time series vary in length among different species and sites, and fish data are only available from Windermere. The original data were initially collected by the Freshwater Biological Association (FBA) but have been collected by CEH and its predecessor Institute of Freshwater Ecology (IFE) since 1989.
