Abstract

Lakewater samples were always taken with an integrating sampler of the type described by Lewis and Saunders (1979). The sampler consists of a PVC tube 5 m long with closure devices at each end that can be triggered by a messenger. When the sampler is retrieved to the boat, the water is released through a piece of surgical rubber tubing into an integrating chamber, where the contents of the sampler are thoroughly mixed. Water is then drawn from the integrating chamber into sample bottles. The integrating chamber incorporates a baffle that prevents contact between the air over the sample and the water, thus allowing collection of samples for analysis of oxygen or other atmosphere-sensitive variables.
