NASA Tests Nearly 20,000 Ocean Samples to Verify Satellite Data
Original: NASA Puts Nearly 20,000 Ocean Samples to the Test to Keep Satellite Ocean Color Data Honest
NASA is analyzing nearly 20,000 seawater samples to calibrate and validate the ocean color measurements collected by its Earth-observing satellites. The effort checks that satellite instruments accurately track phytoplankton, chlorophyll and water clarity across the globe, which matters for climate monitoring and marine ecosystem research.
Why now: The project is a major calibration effort that directly affects the reliability of NASA's ocean color satellite data used by climate and marine scientists.
