PACE OCI Ocean Color
Daily scientific views of chlorophyll-a, colored dissolved and detrital absorption, and particle backscatter, with quantitative values and same-date true-color context.
PACE OCI Gulf of America ocean-color properties
Chlorophyll-a
31.5°N27°N22.5°N18°N
98.8°W94.1°W89.4°W84.7°W80°W
Full Gulf of America daily view for phytoplankton and plume-event screening. Transparent masked areas reveal the same-date true-color land and clouds below; coastal values still require attention to CDOM, particles, and quality flags.
Colored Dissolved + Detrital Absorption
31.5°N27°N22.5°N18°N
98.8°W94.1°W89.4°W84.7°W80°W
Highlights absorption associated with colored dissolved organic matter and non-algal detritus. Transparent gaps reveal same-date PACE true color; hover the numeric layer for the original NetCDF value.
Particulate Backscattering
31.5°N27°N22.5°N18°N
98.8°W94.1°W89.4°W84.7°W80°W
Responds to suspended particles and can help trace sediment-rich plume structure. Transparent gaps reveal same-date PACE true color; hover the numeric layer for the original NetCDF value.
All three scientific panels use daily NASA PACE OCI Version 3.2 NRT 4 km Gulf NetCDF subsets and follow the selected UTC date. Transparent pixels indicate no valid retrieval.
Available-date timeline
How to use this page
- Scan daily true color for river-plume structure, fronts, sediment-rich water, haze, glint, and clouds.
- Use the large daily chlorophyll panel for same-date biological context.
- Use the stacked dissolved/detrital absorption and particle-backscattering panels to preview additional optical-property potential.
- Use native OCI files—not these rendered images—for spectra, transects, values, quality flags, or publication analysis.
Interpretation limits
A bright or colored feature is not automatically a bloom or a concentration measurement. Clouds, sun glint, aerosols, CDOM, and suspended sediment affect coastal imagery and retrieval availability.
For archived dates, chlorophyll, ADG, and BBP all follow the daily selector. These Level-3 mapped fields remain subject to NASA quality screening and retrieval limitations.
