TL;DR: In this paper, recent trends in key eutrophication-related properties, assess their likely ecological impacts, and develop load response curves to guide revised hypoxia-based loading targets called for in the 2012 Great Lakes Water Quality Agreement.

TL;DR: Application of this model to three scenarios of future land use, including business as usual, greater reliance on organic farming methods, and expanded corn-based ethanol production, and two climate scenarios, suggests that riverine N export is likely to increase by as much as 24% in response to heavierfertilizer use for expanded corn production and a 10% increase in annual discharge.

TL;DR: In this article, the authors estimated net anthropogenic phosphorus inputs (NAPI) to 18 Lake Michigan (LM) and 6 Lake Erie (LE) watersheds for 1974, 1978, 1982, 1987, and 1992.

TL;DR: In this article, the authors compared the influence of various assumptions and computational details on the effectiveness of N input estimates in predicting riverine N export, compared eight separate net anthropogenic N input budgets and one soils compartment budget for each of 18 Lake Michigan catchments.

TL;DR: In this paper, the authors quantify trends in P loading to Lake Erie (LE) watersheds, estimating net anthropogenic phosphorus inputs (NAPI) to 18 LE watersheds for agricultural census years from 1935 to 2007.
