Picture the vast expanse of ocean you've seen in postcards or vacation photos - that brilliant blue stretching endlessly toward the horizon. Yet something profound is happening beneath those familiar ...

To track the changes in ocean color, scientists analyzed measurements of ocean color taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite, which has been ...

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. When sunlight hits ...

A green ocean is a productive ocean; the light from the sun helps the phytoplankton — tiny ocean plants — to be productive. This production in turn drives ocean food webs. New research, published in ...

Scientists have unveiled a groundbreaking method (CSAC) to harmonize satellite ocean color data across various satellites, which paved the way for the generation of reliable, global-scale, long-term, ...

Ocean color measurements reveal a wealth of ecologically important characteristics including: chlorophyll concentration, the rate of phytoplankton photosynthesis, sediment transport, dispersion of ...

We've always called Earth the blue planet, but that color might not be permanent. Previous research claims our oceans were once green, and if environmental conditions shift dramatically, a new study ...

NASA has enlisted BAE Systems to create a state-of-the-art instrument to analyze ocean data for the National Oceanic and Atmospheric Administration's (NOAA) Geostationary Extended Observations (GeoXO) ...
