This photograph taken by an astronaut on the International Space Station highlights a late summer plankton bloom across much of Lake Ontario, one of North America’s Great Lakes. Microscopic cyanobacteria, or blue-green algae, can reach such large concentrations and color the water to such an extent that the change is visible from orbit. Harmful algal blooms, or HABs, have been observed in all of the Great Lakes—particularly Lake Erie—and are caused by a variety of factors, including: changes in precipitation; drought; invasive species (quagga, zebra mussels, Asian carp); nutrient loading from runoff and sewage (nitrogen and phosphorus); and warmer than average temperatures. In addition to reduced water quality and human health concerns, algal blooms can also lead to hypoxia—a reduction of oxygen in the bottom waters that kills large numbers of fish and other aquatic life. ...
