GOES-R, May 2004Coastal Ocean Science
HAB Detection & Monitoring Methods
• Ecological– New blooms (Karenia)
– Upwelling variability (domoic acid)
– Other factors (frontal development (Alexandrium)
– GOES Potential for Karenia: diurnal vertical migration
• Optical– Discrimination of Karenia or dinoflagellates from diatoms,
blue greens (GOES additional bands will improve methods)
GOES-R, May 2004Coastal Ocean Science
Resolution difference; 1 km vs. ~300 m; Better characterization of blooms in estuaries
SeaWiFS red band MODIS red

GOES-R, May 2004Coastal Ocean Science
Complementary Ecological & optical methods
GOES enhancements
Improved averages (cloud clearing)
Better determination of optical properties
Additional ecology -diurnal variation
Chl Anomaly Optics; low bb & high chl-a
GOES-R, May 2004Coastal Ocean Science
GOES capabilities for HABs
• Higher resolution, improved detection in bays and near coast.
• Additional bands.– atmospheric correction
• Turbid water• Absorbing aerosol (soot, pollution, dust)
– Improved bio-optical algorithms• Better chlorophyll estimates• Some discrimination of dinoflagellates
