Modeling Hypoxia in the Central Basin of Lake Erie under Potential Phosphorus Load Reduction Scenarios
A 1-dimensional (vertical), linked hydrodynamic and eutrophication model that was previously calibrated and corroborated with 19 years (1987-2005) of observations in the central basin of Lake Erie, was applied as part of a group of models capable of forecasting ecosystem responses to altered phosphorus loads to Lake Erie. The results were part of the effort guiding the setting of new phosphorus...

17 18 A mechanistic model is developed to predict midsummer bottom water dissolved oxygen 19 (BWDO) concentration and hypoxic area on the Louisiana shelf of the northern Gulf of Mexico 20 (1985-2011). Because of its parsimonious formulation, the model possesses many of the benefits 21 of simpler, more empirical models, in that it is computationally efficient and can rigorously 22 account for un...
متن کاملSpatial identification of critical nutrient loads of large shallow lakes: Implications for Lake Taihu (China).
Ongoing eutrophication frequently causes toxic phytoplankton blooms. This induces huge worldwide challenges for drinking water quality, food security and public health. Of crucial importance in avoiding and reducing blooms is to determine the maximum nutrient load ecosystems can absorb, while remaining in a good ecological state. These so called critical nutrient loads for lakes depend on the s...

متن کاملA decline in benthic algal production may explain recent hypoxic events in Lake Erie's central basin
Article history: Received 23 November 2016 Accepted 19 March 2017 Available online 6 April 2017 Since the late 1990s, the central basin of Lake Erie has reputedly experienced an increase in the frequency and severity of hypoxic events. However, total phosphorus (TP) loading, in-lake TP concentrations, chlorophyll a (Chl a), and sediment oxygen demand (SOD) have all declined in the central basin...
