Hypoxia (< 2.5 ppm dissolved oxygen, DO) is an increasingly common seasonal phenomenon in Lakes Huron and Erie. Hypoxia is of particular importance in benthic organisms that live in deep areas likely ...

The researchers have compiled the onset and duration of hypoxia since AD 1700 recorded in varved or laminated sediments for 365 lakes worldwide. The lakes are located in a variety of climates ...

In temperate climate lakes, the researchers found that the amount of low oxygen water is increasing by 0.9% to 1.7% per decade on average and found that the volume of lake water lacking oxygen has ...

New research led by University of Nevada, Reno Assistant Professor Joanna Blaszczak shows hypoxia in rivers and streams is generally much more prevalent across the globe than previously thought.

Hypoxia: Lake Erie’s Invisible Problem. While toxin-releasing cyanobacteria that make up algal blooms in the lake’s western basin are a highly visible risk to public health, hypoxia—a lack of oxygen ...

This year’s forecasts. This year’s Lake Erie harmful algae bloom forecast has a severity index of 7. 5 on a scale of 1 to 10.This is comparable to the three largest blooms since 2011 ...
