  1. Harmful Algal Blooms and GOES-R 49 48 SeaWiFS data from OrbImage, Inc. 47 46 -127 -126 -125 -124 -123 Richard P. Stumpf NOAA National Ocean Service Maryland, USA WA SST GOES-R Users Conference, 2004

  2. Need for Monitoring: Shellfishery, Endangered Marine Mammals, Tourism Manatee County (FL) Red Tide Alert Line: 941-745-3779 Collier County (FL) Red Tide Update Hotline: 941-732-2591 Texas Parks & Wildlife Hotline 800-792-1112 (select fishing, then red tide) Photos: FWCC &Dr. Tracy Villareal, University of Texas

  3. GOES-R value Monitoring and Forecasting Harmful Algal Blooms Impact evaluation Moorings Soon fully operational by NOAA/NOS in Gulf of Mexico;Federal/state/commercial collaboration Email Bulletins to state & local managers Satellite imagery Models Orbimage - SeaWiFS Field samples Orbimage - SeaWiFS

  4. HAB Bulletin Subscribers • Subscribers • County Government • State Government • Federal Government • Non-governmental organizations • Academic Institutions

  5. 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)

  6. Resolution difference; 1 km vs. ~300 m; Better characterization of blooms in estuaries SeaWiFS red band MODIS red

  7. Cloud clearing GOES AVHRR, same day

  8. Complementary Ecological & optical methods Chl Anomaly Optics; low bb & high chl-a GOES enhancements Improved averages (cloud clearing) Better determination of optical properties Additional ecology -diurnal variation

  9. 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
