NOAA Satellites Capture Algae Bloom

NOAA satellites are usually used to give us a view of the atmosphere, however visible satellite imagery has great resolution and often detects othrt interesting phenomena as well. Lately, satellites have become helpful in monitoring algae blooms in the Great Lakes.

Using satellite data in conjunction with weather observations, NOAA researchers have found a way to forecast these blooms. It is important to forecast these events as they can have negative impacts on wildlife, water quality, and aesthetics. Check out the current algae analysis over Lake Erie:

Much of the western portion of Lake Erie is seeing some level of algae concentration. Scientists must monitor the water temperature and surface wind speeds to help forecast algae cover. A wind of 15 knots or higher is enough to break up algae blooms. A notable bloom occurred in 2004 in the same area of Lake Erie, and a satellite was able to capture an amazing image of the extent of the algae cover.
