This dataset describes the hydrogeomorphic structure and lake-tributary mixing in three intermediate-sized Lake Michigan rivermouths: Ford River, Manitowoc River, and Pere Marquette River. Data were collected from May to October 2011. Water chemistry variables were measured with a multiparameter sonde along longitudinal, lateral, and vertical transects. Magnesium, boron, and stable water isotope concentrations were also determined from grab water samples at particular depths.

The code included here was used to analyze data from sediment incubations conducted using sediment cores collected from the Fox and Duck rivermouths (near Green Bay, Lake Michigan).

This dataset contains the recorded water temperatures of specific sites in western Lake Erie during the summer of 2014.

This dataset contains the recorded water temperatures of specific sites in western Lake Erie, Saginaw Bay in Lake Huron, and Grand Traverse Bay in Lake Michigan during the summer of 2015. Sites with just a number were from Lake Erie. Sites from Grand Traverse Bay have a GTB prefix; Saginaw Bay= SB prefix.

Between 1900 and 1932, a copper (Cu) mine operated near Gay, Michigan, along the shore of Lake Superior, discharged approximately 22.8 million metric tons of waste material known as ‘stamp sands’ (SS) to a nearby beach. This pile of SS has migrated via wind and rain along the beaches in northern Grand Traverse Bay and into Buffalo Reef, an important spawning area for Lake Trout and Lake Whitefish. During their first summer, these newly spawned fish consume benthic invertebrates and zooplankton in nearby beach habitats. SS contain elevated concentrations of metals (especially Cu) that are toxic to many invertebrate taxa, and studies have observed very few benthic taxa in areas with very high SS. Here, we sampled...
