NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) platform measures the distribution of phytoplankton, a key indicator of ocean health.
PACE's primary instrument is the Ocean Color Instrument (OCI), a highly advanced optical spectrometer that measures properties of light over portions of the electromagnetic spectrum. OCI enables continuous measurement of light at finer wavelength resolution than previous NASA instruments, extending key system ocean color data records for climate studies.
