NASA’s Portable Remote Imaging Spectrometer (PRISM) can observe Coastal Waters in detail never before possible

NASA - National Aeronautics and Space AdministrationPasadena, CA – A coastal scene with deep blue seas and a coral reef is beautiful to look at, but if you try to record the scene with a camera or a scientific instrument, the results are almost always disappointing. Most cameras can’t “see” underwater objects in such scenes because they’re so dim and wash out the glaring seashore.

These problems don’t just ruin vacation photos. They’re a serious hindrance for scientists who need images of the coastline to study how these ecosystems are being affected by climate change, development and other hazards.

To the rescue: the new Portable Remote Imaging Spectrometer, created at NASA’s Jet Propulsion Laboratory, Pasadena, California. PRISM is an airborne instrument designed to observe hard-to-see coastal water phenomena.

NASA’s Airborne Environmental Monitoring Instrument proves it can be used to monitor Water Quality

NASA - National Aeronautics and Space AdministrationPasadena, CA – Monitoring the quality of freshwater supplies is a global concern, especially in thirsty California, where the San Francisco Bay-Delta Estuary and its watershed serve as a major freshwater source.

Now scientists at NASA’s Jet Propulsion Laboratory, Pasadena, California, and the U.S. Geological Survey, Menlo Park and Sacramento, California, have successfully demonstrated how a NASA-developed airborne environmental monitoring instrument can be applied to help water managers monitor water quality not only in San Francisco Bay, but potentially in other inland and coastal water bodies around the world.
