  • This is a dataset obtained from analysis of lake sediment and overlying water from six sites along a depth gradient, in Loch Leven, Scotland, over a period of one year. Parameters measured from the water and included in the dataset are dissolved oxygen concentration, conductivity, pH, temperature, concentrations of three forms of phosphorus, and ammonium and silica concentrations. Chlorophyll a concentration measured from the sediment surface is included, and within the sediment concentrations of seven different forms of phosphorus are provided.

  • The dataset comprises densities of the major crustacean zooplankton taxa collected from Loch Leven, a large shallow lake in the lowlands of Scotland, between 1972-2007. Data are provided as numbers of individuals per litre for each taxa. The data were collected by the Centre for Ecology & Hydrology and its predecessor bodies, as part of the Loch Leven long-term monitoring programme. Methods of collection varied over the period of collection with samples generally collected at fortnightly intervals. There are significant gaps in the dataset during the 1980s when funding for monitoring was limited.

  • The dataset comprises counts of four planktonic diatom taxa collected from Loch Leven from 1968-2007 by staff at the Centre for Ecology & Hydrology and its predecessor bodies, as part of their long-term monitoring programme of the lake. Count units are the density of cells per millilitre of water for four species; Asterionella formosa, Aulacoseira spp, Diatoma spp, Unicellular centric diatoms. Counts are of weekly to monthly frequency and from a single sampling station Full details about this dataset can be found at https://doi.org/10.5285/de5ca6cc-02e9-42bc-a39e-80ec8acbffba

  • A subset of the Loch Leven long-term monitoring project dataset. This subset contains data collected from Loch Leven between 1985 and 2007 at three sampling sites in the lake. It includes results of chlorophyll, phosphorus, and silicon analyses as well as conductivity and water temperature measurements. The data relate to water samples taken at fortnightly or monthly intervals. Data available in digital form is described here. Additional data currently held as hard copy, will become available once digitised. Full details about this dataset can be found at https://doi.org/10.5285/2969776d-0b59-4435-a746-da50b8fd62a3

  • The dataset comprises counts of ten waterfowl species collected from Loch Leven from 1968-2007 by staff at Scottish Natural Heritage (SNH) and its predecessor bodies (Nature Conservancy), as part of their long-term monitoring programme of the lake. Counts are for the whole loch and represent an annual peak count based on the monthly counts recorded from September (of the year indicated) through to March (of the following year).
