The Earth observation data archived here have plenty of value to the study of aquatic ecosystems. Landsat satellites can capture harmful algal blooms, for example. Spaceborne sensors can also record land surface temperatures, and that includes water surfaces. On this episode of Eyes on Earth, we hear about how a sensor called ECOSTRESS can be used to measure water temperatures at different times of day, and how those measurements could be useful in the monitoring and management of the endangered Delta smelt. ECOSTRESS data are available through the NASA Land Processes Distributed Active Archive Center (LP DAAC), located in the USGS EROS Center.
