Study reveals how dissolved organic matter in the Great Lakes ice may impact spring melt

Study reveals how dissolved organic matter in the Great Lakes ice may impact spring melt
Great Lakes Echo
By Riley Wilson Ice covering the Great Lakes stores organic carbon, which is released in a burst during spring melt. As climate change reduces ice cover, researchers say this seasonal surge of energy may be shrinking, with uncertain consequences for these freshwater systems.

Great Lakes show signs of declining PFAS pollution

Great Lakes show signs of declining PFAS pollution
Great Lakes Echo
By Riley Wilson Rising levels of per- and polyfluoroalkyl substances (PFAS) contamination are prompting scientists to question whether the Great Lakes can safely sustain surrounding communities. A recent study shows signs of declining PFAS pollution in these waters using archived fish.
