Abstract

Bathymetric descriptions of thirty four Galloway lochs are given together with water quality data for 1983-85. Results of diatom analysis of surface sediment collected from each loch are presented in tabular form. Lake water pH is generally lower in November samples than in samples collected in summer months. Cation exchange, following deposition of sea salts on peaty catchments, is suggested as a partial winter period. cause of pH depression in the winter period. Where lakes are deep enough, summer thermal stratification usually occurs between 5 and 8 m depth. Floristic diversity of the periphyton component of surface sediment diatom assemblages is shown to increase generally with pH.
