Eyes on Earth Episode 114 – The Color of Water with Landsat

Typically, we use Landsat data to study changes on the land—you know, Land sat. In this episode 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 United States. 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 Office of Science and Technology Policy’s 2023 “Year of Open Science” campaign.
