At the 8th Binational Meeting of the Lake Erie Millennium Network, 125 scientists gathered at the University of Windsor in Ontario to hear experts weigh-in on the health of the southernmost, warmest and shallowest of the Great Lakes.
They presented research on everything from climate change, water quality, phosphorous, agricultural run-off, cyanobacteria (blue-green algae), hypoxia (deficiency in oxygen), cladophora (green algae) to ice, invasive species, sediment concentrations, and much, much … [more…]
CAFOs often store animal waste in massive, open-air lagoons, like this one at Vanguard Farms in Chocowinity, North Carolina. Bacteria feeding on the animal waste turns the mixture a bright pink. picstever / Flickr / CC BY-ND 2.0
It has been almost a year since Hurricane Florence slammed the Carolinas, dumping a record 30 inches of rainfall in some parts of the states. At least 52 people died, and property … [more…]

Rivers deliver sediment from land to the ocean. This sediment contains nutrients which can feed microscopic algae in water. But, if there is too much sediment and nutrients, delivered by floods from land-based erosion, algal blooms can occur that have negative effects on the Great Barrier Reef.
The challenge is that sediment comes from many different locations and we need to know … [more…]

Elevated concentrations of strontium, an element associated with oil and gas wastewaters, have accumulated in the shells of freshwater mussels downstream from fracking wastewater disposal sites, according to researchers from Penn State and Union College.
"Freshwater mussels filter water and when they grow a hard shell, the shell material records some of … [more…]
Certain groups of animals are declining at an alarming rate—and none more so than those living in freshwater.
This year’s Living Planet Report shows that populations of animals—including mammals, birds, fish, reptiles, and amphibians—plummeted by 60% between 1970 and 2014. But those living in freshwater are experiencing a far more drastic decline: 83% since 1970. It’s a sobering statistic and one tied directly to the ever-increasing pressures that people are … [more…]
