In Episode 114 of Eyes on Earth, we learn how satellite images and pixels of water, along with actual water samples, are helpful in determining the productivity of lakes across the U.S.

We talk with Mendenhall Fellow and Research Geographer Dr. Michael Meyer about a recently released, freely accessible dataset that uses a metric called lake trophic state to validate the Landsat observations of thousands of lakes. The dataset was also named a USGS Open Science Success Story as part of the White House’s Office and Science and Technology to the President’s “Year of Open Science” campaign.

Meyer works within the Hydrologic Remote Sensing Branch of the Water Resources Mission Area and is based in Madison, Wisconsin.
