Satellite Data Derived Cyanobacteria Concentrations

Detailed Description

Two aerial images that demonstrate satellite-derived cyanobacteria concentrations in surface waters from an area in Florida. The top image is true-color photograph, and the bottom image is from the Medium Resolution Imaging Spectrometer (MERIS) sensor on the Envisat satellite, taken October 1, 2011. Data from the sensor lets scientists assign quantitative values for cyanobacteria concentrations, which are represented using a color scale ranging from blue (low concentrations) to red (high concentrations).
