Measuring Cyanobacteria Toxins in the Great Lakes

University of Wisconsin-Milwaukee

Harmful algal bloom (HAB) monitoring has become a popular topic of research in limnology. While most monitoring efforts center on chlorophyll measurement, the real impacts of HABs are connected to the toxins produced by cyanobacterial blooms, which can be challenging to measure. Due to their impact on human health, establishing models that allow for the […]

Using Data Buoys to Monitor Southern Green Bay

University of Wisconsin

Green Bay has suffered continuous influxes of pollutants and contaminants from the Fox River due to non-point source runoff in the watershed. Deterioration of the bay’s water quality extends well into the last century, and while cleanup efforts in the bay have been successful overall, continuous monitoring of the bay is important to ecosystem management. […]

3.7 Chlorophyll and Blue-Green Algae

Chlorophyll is a pigment found in plant cells and some microorganisms, such as algae and cyanobacteria. It gives these organisms their characteristic green color by reflecting the green wavelengths found in sunlight and plays a central role in the process of photosynthesis. There are several different chlorophyll molecule variants that exist. Chlorophyll-a is present in […]
