5. Considering: potential for human food supply recreation and management (i.e. marine protected area monitoring and regulation) socio-economic value: ~US$6,000 / Ha /year (Costanza et al. 1997). (swamp/floodplains ($8,000 ha/y), wetlands ($5,000 ha/y), mangroves ($3,000 ha/y), estuaries ($1,500 ha/y)) -up to $675 billion annually in fish, seafood, tourism, and coastal protection worldwide -$17 billion in U.S. tourism -1 billion people rely on reef fish for food Coral: Socio-Economic Importance

6. Over 60% of the world's reefs are under threat. Factors: increasing temperature, increasing dissolved inorganic carbon in ocean waters, increased use of coastal resources including fishing, coastal development, pollution Tropical Coral Reefs: Ecosystems under Stress

10. NOAA CRW DSS The 2005 Bleaching Event in the Western Hemisphere. The image shows the Degree-Heating Weeks (DHW) accumulated through 1 November, 2005. Note high DHW (yellow-orange colors) in the eastern Caribbean Sea. Significant bleaching took place in the U.S. Territories and adjacent islands. DHW corresponds to one week of SST exceeding the maximum summer SST by one ºC. A value of two DHWs indicates two hot weeks, but is also equivalent to one entire week of SST exceeding the maximum summer SST by two ºC.

11. Objectives of NASA-NOAA-USF Program Assess value of high-spatial resolution SST data (MODIS, AVHRR) and the Global Coral Reef Millennium Map (Landsat) to improve the NOAA Coral Reef Watch decision support system (CRW DSS) Help further develop the CRW DSS Develop end-to-end evaluation and feedback mechanism to meet user needs. Link to plans for: Hyperspectral and Infrared Imager (HyspIRI) Landsat Data Continuity Mission (LDCM) NPP, NPOESS, other environmental satellites

12. Help develop the CRW DSS includes: Assess value of existing CRW products. Span scales: from ICON/CREW high temporal & spatial resolution to global CRW Evaluate optimal spatial and temporal resolutions for coral reef applications. Experimental 1, 4, and 50 km spatial resolution products from MODIS and AVHRR. Validate in partnership with NOAA ICON/CREWS Consider enhanced stress indices (e.g. cold, heat, water quality, other) Integrate Coral Reef Millennium Map products. Visualization and “knowledge” interface, tailored to monitoring and policy-making.

13. Evaluation component Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado at Boulder (Mark Mcaffrey, Susan Lynds) Will verify that the program meets goals of the NASA Applied Sciences Program Will assess: Efforts to document development of products and tools Effort to solicit feedback and assistance on use and usability Effort to learn whether the task meets the needs of identified stakeholders

High resolution preserves spatial patterns of importance to reefs High-resolution (1-km) AVHRR SST imagery (NOAA-16 satellite) showing small-scale ( ∼ 1020 km, ∼ < 1 ◦ C) frontal eddies (annotated with black arrows) along the shallow isobaths in the Florida Straits January 22, 2002 at 7:36 GMT and January 23, 2002 at 18:45 GMT. Eddies are due to shelf wave dynamics, and they cannot be detected by other coarser resolution data (4 km or lower).

20. January 25 – February 17, 2010 78 sites were surveyed across the Florida Reef Tract from the Lower Keys to Martin County  Areas impacted the most were the inshore and mid channel zones from Summerland Key in the lower Keys through Biscayne National Park.  Forereef zones region-wide, reefs west of Summerland Key and reefs north of Biscayne National Park were, much less affected but were highly impacted. Highest coral mortality seen in the last 5 years. Frequent observations showed that corals would generally pale for a day then die.  All species were affected Cold water stress monitoring
