Blue-green algae is typically found in lakes with heavy nutrient runoff from nearby farms, lawns and roads. But researchers are now trying to figure out what's causing the sometimes harmful blooms in more remote lakes in northern Minnesota, including in the Boundary Waters Canoe Area Wilderness.

Even if most cyanobacteria blooms in Canada's lakes happen during the hottest periods of summer, water temperature seems to have little to no impact on the development of these potentially toxic bacteria better known as blue-green algae.

Scott Hotaling, an Assistant Professor in the Department of Watershed Sciences in the Quinney College of Natural Resources, is exploring how the watermelon-tinted blooms of snow algae impact mountain snowpack—where they come from, what triggers a bloom, and what factors influence the size, scale and magnitude of snow algal blooms.

Huge blooms of phytoplankton — microscopic algae floating on the ocean's surface — have become larger and more frequent along the world's coastlines...

Algae that commonly grow on snow in the Pacific Northwest have been ignored in melt models, but their presence significantly increases snowmelt compared with clean, white snow, according to a study conducted on Mount Baker in the North Cascades, Washington.

Climate change and human activity have been putting pressure on water bodies worldwide, and Canada's vast network of lakes is no exception. Over the past decades, increasing nutrient levels have led to a process called eutrophication, in the shallow lakes dotting Quebec's Laurentian region north of Montreal. These changes have led to a surge in algae blooms, rendering the lakes unusable and possibly disrupting the…

Cyanobacteria have overrun this lake an hour outside West Palm Beach, and excessive rain could spread that algae to nearby waterways.

The prevalence of blue-green algae blooms in southern Ontario will become more frequent as temperatures rise, say Brock University researchers.

Researchers at Oregon State University have developed a new way to monitor the danger associated with algae blooms: "sniffing" the water for gases associated with toxins.

Even if most cyanobacteria blooms in Canada's lakes happen during the hottest periods of summer, water temperature seems to have little to no impact on the development of these potentially toxic bacteria better known as blue-green algae. Details of this discovery made by an international research team including scientists from Université Laval were published in the journal Harmful Algae.

In the lake-rich regions of the world, algae blooms are a growing problem. Not only are the floating green scums a nuisance for anyone hoping to enjoy the water, they can turn toxic and threaten public health.

Florida's 156-mile-long Indian River Lagoon (IRL) borders five different counties and has five inlets that connect the lagoon with the Atlantic Ocean. This estuary has recently experienced numerous phytoplankton bloom events due to increased seasonal temperatures and environmental impacts.

Florida Gov. Ron DeSantis announced the awarding of over $13 million toward 10 projects aimed at preventing and cleaning up harmful blue-green algae blooms.

Over 2,300 lakes and rivers across the contiguous U.S. are hosts to blue-green algae blooms, according to data.

South Florida's drinking water has become increasingly threatened by shrinking wetlands, algal blooms, and now, saltwater intrusion.

An analysis of lake water quality across the United States suggests a northward shift in areas at higher risk for toxic algae blooms due to climate change.

Ponds, rivers, and lakes all over are getting hit by blooms of blue-green algae.

Colorado's lakes serve as a needed respite during sweltering summer days, but as climate warms, the state's lakes are becoming more susceptible to toxic blooms of algae.

A team of Earth scientists affiliated with multiple institutions in China and the U.S. has found that coastal algae blooms (also known as phytoplankton blooms) have been getting bigger over the past couple of decades. In their study, published in the journal Nature, the group analyzed satellite data supplied to them by NASA to compare the size and frequency of algae blooms along the coasts of the world's continents.

The algal toxins were discovered March 12 after state health officials tested the water.
