Coral reefs are among the most valuable ecosystems on Earth. Unfortunately, they are declining due to manmade and natural threats. NOAA’s National Coral Reef Monitoring Program (NCRMP) is a massive, collaborative effort that was developed to collect scientifically sound, geographically comprehensive biological, climate, and socioeconomic data in U.S. coral reef areas. In this episode, we speak with Shay Viehman, a Research Ecologist with NOAA’s National Ocean Service in the National Centers for Coastal Ocean Science, and a contributor to the NCRMP, to learn how NOAA divers turn the data they collect from underwater missions into usable summaries that help scientists study and protect U.S. coral reef ecosystems.
