dc.description.abstract	Representative and accurate measurements of both autotrophic and heterotrophic production in lakes are essential parts of basic limnological research and lake monitoring, management, and restoration programs. We describe preliminary data that demonstrate the utility of a continuously recording, in situ respirometer for measuring diel oxygen production and consumption in lake water. The data can be used to compute P, R, P vs. I, P vs. T, P/R, P/B and other basic parameters of primary productivity and heterotrophic activity per unit volume of lake water or per unit chlorophyll. In combination with information on morphometry and water residence time, these volumetric production estimates can be used to compute integrated whole lake metabolism and production budgets. In our preliminary studies we found that heterotrophic processes dominated the water column in Lake Oglethorpe, Georgia.	en_US
