  1. Issues and Expectations for COAST Mark R. Abbott College of Oceanic and Atmospheric Sciences Oregon State University

  2. Coastal Oceans Applications and Research • Ocean/land/atmosphere interactions • Local and global processes • Increasing pressures on coastal systems • Ecosystem integrity and adaptive management

  3. June 9-16, 2000 June 25, 2000 SST Surface Chlorophyll SST Surface Chlorophyll Columbia River Newport Heceta Bank Cape Blanco

  4. Intermittent Upwelling More Persistent Upwelling

  5. Balanus glandula Recruitment varies considerably along the coast Acorn Barnacle

  6. Mean Integrated Chlorophyll GLOBEC LTOP Surveys, 1997-2003 Note strong increases in July 02 and July 03 (Wheeler, 2003)

  7. Decorrelation Scales in the California Current • Nearshore (within 200 km) • SST  Chlorophyll • Fluorescence/Chl. < Chlorophyll • Imbalance between light harvesting and utilization • Transition (200 - 400 km) • All scales increase • Coherent flow features (e.g., eddies) • Offshore (> 400 km) • SST > Chlorophyll • Fluorescence/Chl.  Chlorophyll • Processes in balance

  8. Why Are SST and Chlorophyll Scales So Different Offshore? • Different physical processes controlling SST and chlorophyll in the offshore region versus nearshore in active upwelling zone • Change in balance of light harvesting/utilization suggests shift from non-equilibrium strategy nearshore to equilibrium strategy • Exploit variability in light and nutrients through storage, buoyancy, etc.  large diatom chains • Offshore community  small forms, flagellates

  9. SST, Chlorophyll, and Fluorescence

  10. Nearshore Communities

  11. Frontal Communities

  12. Challenges for Coastal Remote Sensing • Time and space scales • Optically complex • Wide range of processes, including land/ocean interactions • Wide range of applications beyond chlorophyll and productivity

  13. Unique Capabilities • Value of time-continuous sampling • Links to other observing system components • Other GOES sensors • Polar orbiters • IOOS • Spatial resolution • Spectral resolution

  14. Developing a CWI Capability • Different process than NASA science team • Science-based requirements are essential but must be linked to specific applications • Different than NPOESS • Science community is an active partner early in the process • Links between applications and sensor capabilities • Tradeoffs, thresholds, goals, etc. • End-to-end system needs • Science underlying new applications • Feeds into GOES-R Risk Reduction activities • Build community awareness and support • White paper • Brochure • Seminars
