Recent patterns in Lake Erie phosphorus and chlorophyll a concentrations in response to changing loads

Despite the initial success of extensive efforts to reduce phosphorus (P) loading to Lake Erie as a part of the Great Lakes Water Quality Agreement, Lake Erie appears to be undergoing a re-eutrophication and it is plagued by harmful algal blooms. To offer insights...

Great Lakes ice duration, winter severity index, cumulative freezing degree days, and atmospheric teleconnection patterns, 1978-2018

This report investigates interannual variability in ice coverage (Bai et al., 2012; Assel et al., 1998; Assel et al., 2013). We conduct analyses of the ice coverage records—freeze-up date, break-up date, duration and annual maximum ice coverage (AMIC)—with air...

Nutrient loading and nonstationarity: The importance of differentiating the independent effects of tributary flow and nutrient concentration

The “phosphorus loading concept,” or more generally the “nutrient loading concept,” arose from Richard Vollenweider’s work in the 1960–1970s that showed correlations between phosphorus loads and various eutrophication symptoms. The initial success of target...
