GMES Summer Experience Showcaseđź”…
From Milwaukee to Detroit, this summer took Geology PhD candidate Karl Bosse onto the Great Lakes aboard the 180-foot R/V Lake Guardian as part of the U.S. Environmental Protection Agency (EPA) summer survey of Great Lakes water quality.
Alongside two colleagues from Michigan Tech Research Institute (MTRI), he sampled the optical properties of Lakes Michigan and Huron, collecting data that will help develop and validate satellite-based methods for monitoring freshwater quality.
The team also put new tools to work, including an Imaging FlowCytobot (IFCB) that captured images of phytoplankton and zooplankton in the water. These observations will help researchers better understand Great Lakes phytoplankton communities using hyperspectral satellite imagery.
From measuring water quality to deploying instruments and watching the Mackinac Bridge come into view, this cruise offered a unique combination of field research, technology, and Great Lakes exploration.
