A new paper published in the journal Ecological Informatics presents a long-term annual total P (TP) budget for the Lake St. Clair–Lake Erie system, averaged over a 14-year period, from 2003 to 2016. The paper is authored by ERG members Serghei Bocaniov and Philippe Van Cappellen, together with Don Scavia from the University of Michigan. The results show that the TP output from the system substantially exceeds the sum of the external TP inputs, hence implying a major role of in-lake P mobilization processes. Overall, the latter represent about one quarter of the total P input to the water column of Lake Erie. Important in-lake P mobilization processes that have been largely overlooked ainclude shoreline erosion and sediment resuspension.
