Satellite-based Mapping

Remote sensing, including aerial and satellite imagery as well as underwater acoustic imagery, are being analyzed to quantitatively and efficiently assess both the regional extent of EWM (identifying newly invaded areas at an early stage without intensive field monitoring based on the spectral characteristics of EWM) and the local outcomes of EWM treatments, enabling managers to monitor the impacts of and improve the techniques used for combating this invader and restoring natural habitat in important coastal areas of the Great Lakes.

Sonar Surveying

EdgeTech sonar data collected in Torch Bay in summer 2014.

Using the Great Lakes Research Center?s ultra-high resolution EdgeTech Side Scan Sonar, the aquatic vegetation in the study areas is being surveyed by boat

Hydrodynamic Modeling

Advanced next-generation, Great Lakes numerical, hydrodynamic modeling is underway at the Great Lakes Research Center (GLRC) at Michigan Tech, utilizing the new supercomputer “Superior.” This is critical for our understanding of potential dispersal paths of EWM propagules and the water and nutrient conditions that foster EWM proliferation.
