June precipitation appears to be positively correlated to algae blooms in Lake Erie. Looking at monthly precipitation data readily-available from Weather Underground and comparing it to the Western Lake Erie Algae Bloom Severity Index, I was surprised by the strength of the correlation (0.6, 0.85 with an “outlier” removed). June precipitation was the only month to correlate to the Severity Index in my data set and I was surprised that …

Lake Erie Algae Bloom
This September 3, 2011 MODIS image of Lake Erie reveals a bright green algae plume concentrated in the western basin. The western basin of the lake is the shallowest part and receives discharge from the Maumee River, the largest river watershed in the Great Lakes with 6,354 square miles (16,460 square km) of land drainage. Land use in the watershed is about 85 percent agricultural and growers typically use a …

MODIS Reveals Major Sources of Sediment
It’s mud season in the Midwest and the MODerate Imaging Spectroradiometer (MODIS) 250m true color band beautifully displays the tell-tale sediment plumes entering western Lake Erie (left). Updates of Great Lakes MODIS imagery are available here MODIS is a multi-band imaging instrument mounted on two Earth-orbiting satellites, the Terra, and the Aqua, both part of the NASA-led international Earth Observing System. Between the two of them, the entire Earth is …
