Loch Leven diatom counts 1968-2007

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

Provenance & quality

Validation of data was in line with protocols referenced in the supporting documents. The dataset was quality controlled by all three authors who have worked on the Loch Leven long-term monitoring project since 1968. Dr Tony Bailey-Watts counted all the pre-2001 data and this was checked and collated by Alex Kirika. Dr Laurence Carvalho counted and checked all the data from 2001-2007.
