NCCOS/NOAA Satellite Imagery, Making the Connection, Todd Thurlow


If you’re like me, you might wonder about the various satellite images in the news and on social media showing the cyanobacteria, also known as blue-green algae, in Lake Okeechobee. What’s the connection between the colorized and the not? How do the scientists determine the colorized image? Where do they come from?

In this post, I share a link to my brother, Todd Thurlow’s latest creation, “NCCOS HAB Images.” This exciting site juxtaposes an experimental product of the National Centers for Coastal Science, NCCOS, being used to track Harmful Algae Blooms, HABs, in Lake Okeechobee, to NOAA True Color, or enhanced traditional satellite images.
The NCCOS images are referenced by The South Florida Water Management District, however, experimental. Experimental or not they are cool, tell us a lot, and they are interesting!

Before relying on a CICyano (Chlorophyll Cyanobacteria Index) image, scientists must first look at the “true color” version to determine if clouds or sunlight reflections have corrupted the data. Todd has made it easy for us to compare the NCCOS “Chlorophyll Cyanobacteria Index” pictures to the corresponding “True Color” picture. He processed hundreds of images, putting them side by side. Generally, if there are clouds on the right image, then the left image may not be so reliable. But if there are no clouds on the right, then the left image is a good indicator of algae.

This site is an awesome visual tool we can now reference as we continue to learn about HABs in Lake Okeechobee. Technology is a powerful path for connecting to a “better water future.”
