algal blooms

Researchers find a widespread decline in dissolved oxygen levels in lakes, which is known to reshape ecosystems.

Tests point to a toxic algal bloom that might have led to the unprecedented deaths of hundreds of African elephants in Botswana earlier this year, but the evidence isn’t conclusive.

Biological production of this greenhouse gas, once thought to be the reserve of anaerobic microbes, occurs in these widespread, photosynthesizing cyanobacteria.

Understanding the dinoflagellates that regularly wreak havoc on marine and nearshore ecosystems in the Gulf of Mexico could help researchers mitigate the damage they cause.

A full description of the lifecycle of Karenia brevis could lead to improved monitoring, prediction, and mitigation of the harmful algal blooms it regularly causes.

The majority of lakes studied experienced increased bloom intensity over the past few decades.

Freshwater fish suffer from low levels of oxygen in the country’s rivers, while bats are unable to survive the extreme air temperatures.

The federal agency launches a new system to collect nationwide data on outbreaks of harmful algae and associated health problems.

Results could explain why the marine mammals have been stranding on the West coast in record numbers.

Iron fertilization might be less efficient at storing carbon in the deep ocean than previously reported.

Marine viruses may be key players in the death of massive algal blooms that emerge in the ocean, a study shows.

Citizens of Ohio’s fourth-largest city can drink from the tap again, but the root causes of the Lake Erie algal blooms that shut off the flow for two days remain.

An increasingly common algal growth, found in rivers the world over, is caused by changing environmental conditions, not accidental introductions.

Turbulence interacts with the stabilizing efforts of motile phytoplankton to create small-scale patches of toxic, bloom-forming organisms.

Meet the research team that uncovered an algal bloom churning in freezing Arctic waters.

Spawning algal blooms by fertilizing the Southern Ocean with iron could help sink atmospheric carbon to the deep ocean—and maybe slow the course of climate change.

Algal blooms are appearing under the ice in the Arctic Ocean in areas thought to receive too little light to support photosynthetic life.
