Satellites to Be Used in Detecting Freshwater HABs

NOAA, NASA and the EPA recently announced a $3.6 million effort to develop an early warning system for detecting harmful and nuisance algal blooms in freshwater bodies, such as the Great Lakes. A central part of this plan is the use of satellite remote sensing capabilities to identify algal blooms. The VIIRS sensor on the Suomi NPP satellite, which provides both true color imagery and derived products such as chlorophyll concentration, will provide many of these critical measurements. Shown here is a VIIRS true color image of the Great Lakes from March 21, 2012, during a massive bloom even in Lake Erie.
