Total phosphorus and water flux at a restored hydrologic connection at Ottawa National Wildlife Refuge in 2013 and 2014

This tabular data set contains estimates of total phosphorus concentration and mass, as well as measurements of water discharge and volume at a diked wetland pool (Pool 2B) that was reconnected to a Lake Erie tributary (Crane Creek) via a water control structure in March 2011. Sampling occurred during 2013 and 2014. In addition, this data set contains evaluations of movement of total

Diet Data from the Western Basin of Lake Erie Examining White and Yellow Perch, 2012-2016

A fish’s diet is the integrated response of multiple ecological interactions including habitat use, foraging behavior, prey community characteristics, and inter-specific interactions. Fish diet samples have quantified how the invasion of white perch into Lake Erie in the early 1950s has influenced interactions with native yellow perch, which are similar in morphology and habitat u

Land cover map including wetlands and invasive Phragmites circa 2017 for Green Bay

The first basin-wide map of large stands of invasive Phragmites australis (common reed) in the coastal zone was created through a collaboration between the U.S. Geological Survey and Michigan Tech Research Institute (Bourgeau-Chavez et al 2013). This data set represents a revised version of that map and was created using multi-temporal PALSAR data and Landsat images from 2016-2017. In add

Measured and Modeled Water Velocities in the Detroit River Near Belle Isle from 2014-2017

This data set contains water depths and velocities measured with an acoustic Doppler current profiler (ADCP) used to develop a three-dimensional computational fluid dynamics (CFD) model. The CFD model was used to inform fish spawning habitat remediation projects in the Detroit River near Belle Isle. Prior to construction of three fish spawning reefs in 2016, ADCP measurements were made

Bottom Hardness and Surficial Substrate Composition of Fish Spawning Reefs in the St. Clair-Detroit River System from 2012 - 2018

This data set contains bottom hardness and surficial substrate compositions measured as part of a study evaluating the maturation of fish spawning reef restoration projects in the St. Clair-Detroit River System. Five spawning reef complexes (Middle Channel, Harts Light, Pointe Aux Chenes, Grassy Island, and Belle Isle) constructed with 10-20 cm broken limestone from 2012-2016 were eva

Water Chemistry of Great Lakes Tributaries, 2017-2018

Chemical composition of fish bones can be used to trace fish migrations and other movements (e.g., use of tributaries for spawning). Chemical composition of water is required to be able to trace fish migrations or movements to particular rivers or streams. Because water chemistry can change over time due to changes in land use, tectonic movements that alter groundwater pathways, polluti

Using turbidity measurements to estimate phosphorus and sediment flux in a Great Lakes Coastal Marsh, in Ohio.

Great Lakes coastal marshes have the potential to filter water coming off of the landscape and remove sediments and nutrients before they reach the lakes. However, this ability has largely been neutralized as vast areas of coastal wetlands have been isolated behind dikes; while at the same time the Great Lakes continue to suffer from excess phosphorus loading. In this study we used high-fre...
