Abstract: This project investigates phosphorus dynamics in Androscoggin Lake at a higher time resolution than current steady-state models, using automated and manual sampling to resolve events at timescales of minutes to weeks. It focuses upon (1) external loading from the 30-Mile River watershed as a function of stormflow, (2) water-column dynamics in Androscoggin Lake in relation to river inputs and weather, and (3) the potential for internal phosphorus loading from sediments in relation to changing dissolved-oxygen concentrations in overlying waters. Integration of these records provides insight into the controls on phosphorus loading and their sensitivity to potential future climate and land-use change.
