Chlorophyll Concentrations
Kaneohe Bay, HI

The Rapid Prototyping Capability (RPC) node at NASA Stennis Space Center, MS, was
used to simulate NASA next-generation sensor imagery over well-known coral reef
areas: Looe Key, FL, and Kaneohe Bay, HI.
The objective was to assess the degree
to which next-generation sensor systems—the Visible/Infrared Imager/Radiometer Suite
(VIIRS) and the Landsat Data Continuity Mission (LDCM)—might provide key input to
the National Oceanographic and Atmospheric Administration (NOAA) Integrated Coral Observing Network (ICON)/Coral Reef Early Warning System (CREWS) Decision Support Tool (DST).
The DST data layers produced from the simulated imagery concerned water quality and benthic classification map layers. The water optical parameters of interest
were chlorophyll (Chl) and the absorption coefficient (a). The input imagery used
by the RPC for simulation included spaceborne (Hyperion) and airborne (AVIRIS) hyperspectral data. Specific field data to complement and aid in validation of the overflight
data was used when available.
