Ocean Color Data Access and Tools

NASA has ocean color datasets that help researchers study the composition of ocean water and the processes that take place within it. Access a range of data and data tools such as AppEEARS, SeaDAS, and Giovanni to make the most of ocean color data.

Featured Ocean Color Observation Method: PACE
NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) platform measures the presence of phytoplankton, which are microscopic marine algae that can tint the ocean green and other colors. Phytoplankton function like plants in the ocean because they take up carbon dioxide and use it in photosynthesis to produce carbohydrates and oxygen. Phytoplankton help form the base of the ocean's food chain and are a key component of the carbon cycle. PACE and its optical spectrometer called the Ocean Color Instrument (OCI) can observe light reflected by phytoplankton and the ocean in unprecedented detail to provide essential data on its condition and health.

This is an image showing simulated chlorophyll concentrations in the ocean on March 21, 2022. The image has a black background. Regions colored in blue represent areas of low chlorophyll concentration, green are medium, and red areas have high levels. The image has strips of black running through the colored areas from the upper left to the lower right to show PACE’s orbital track around the globe and places across the ocean where it has not scanned.

Preparing for PACE Data

Simulated data help Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) users prepare a day in the life of the new satellite.

This rectangular image shows phytoplankton levels along Florida and the East Coast of the United States, the Bahamas, and Cuba. Land is colored in muted shades of brown and green, water is dark blue, and snow is white. Nearshore are bands of light to dark green depicting picoeukaryote organism levels. Further out to sea are regions in variations of light blue showing the presences of prochlorococcus cyanobacteria.

New PACE Data Tutorials
