A seasonal study of the surface biota of the Dubh Lochan was carried out during the period July 1980 to September 1982. Four surface sites were chosen, three in bay areas and one in open water. Samples were collected to a depth of 5mm. These were compared to depth samples collected at the open water site. The following parameters were measured:- water temperature, oxygen content, surface tension, Secchi disc depth, incident solar radiation, pH, alkalinity, acidity, conductivity, nitrate, nitrite, phosphate, ammonia, DOC, TOC (and hence POC), DON, PON (and hence TON), chlorophylls a, b and c, the carotenoids and phaeopigments. Phytoplankton and zooplankton enumeration, heterotrophic bacterial density and 14C carbon fixation rates were determined. Two 24h surveys of the physical, chemical and biological components of the surface layer were carried out. Weather data was kindly provided by the Clyde River Purification Board. During 1981, wind induced cooling of the surface layer resulted in surface water temperatures of up to 2
