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
