Deep waters in temperate climate lakes have already lost almost 20 percent of their oxygen supply. Originally published on Nexus Media. By Kaitlin Sullivan On a sweltering morning last July, thousands of dead fish washed onto the northeastern shores of Pokegama Lake, 60 miles north of Minneapolis. Deb Vermeersch, an official with … [continued]
Climate change is contributing to falling oxygen levels in lakes across the world, according to a new study published in the journal Nature yesterday. Previous studies have shown falling oxygen levels in individual lakes, but this study is the first to look at so many lakes globally, as researchers gathered data from … [continued]
Aquatic ecologist John A. Downing happily remembers childhood holidays at his family’s vacation home at Wabana Lake, near Grand Rapids, Minnesota. The lake was upstream “from almost everything,” making it difficult for pollution to reach it, he said. But some eventually got there anyway. “It’s still beautiful, but somewhat greener around the edges,” he said. “I have been diving in these lakes since I was 9 years old, and as I get older, I notice there are more frequent surface algae blooms.”
Climate change, through the impacts of increasingly extreme rainfall events and melting permafrost on the organic matter content of various bodies of water, may lead to a stunting of the ability of the sun’s ultraviolet light to disinfect the world’s lakes and coastal waters, according to a new study published in Scientific Reports.
An ecologist and an engineer at Michigan State University are working together to create robot fish that can better monitor various factors in aquatic environments. [social_buttons] Combining the brilliance of nature with some top-notch engineering, these two scientists are on to something and getting the funding for it. The researchers … [continued]
