4. Objectives of the Program Assess and meet needs in coral reef research, management, education Assess value of high-resolution (1 km ) data (MODIS, AVHRR, other) Link to higher-resolution maps Global Coral Reef Millennium Map Landsat, other present and future sensors

5. Accomplishments: 2010-2011 Completed user survey for NOAA Coral Reef Watch products. Developed global high-resolution 4km SST climatology Deployed a website with 1 km Coral Reef Watch (CRW) products for the Florida Keys. Developed prototype cold water event index (cold snap index) for the Florida Keys. UNEP WCMC integrated the NASA Coral Reef Millennium Map into their online databases with a Mapserver interface (http://data.unep-wcmc.org/datasets/13).

6. MARK – add your slides here I have some slides here you can use (or delete…) Add: CRW background Approach to the NASA-NOAA DSS program New work on climatologies New medium and high res high temperature stress products (AVHRR, MODIS)

7. High Resolution Prototype CRW Products based on: 4 km AVHRR Global Pathfinder Climatology 1 km MODIS and AVHRR (Test area: Florida Keys National Marine Sanctuary)

8. 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 coarser resolution data (4 km or lower).

10. Issue One: Climatology Objective: Build new climatology at higher resolution Approach: –Use Pathfinder SST 20 y, cross-referenced –4 km, nightime, best data –Period: Original 50-km NOAA Operational: –Jan 1985 to Dec 1993 excluding 1991 and 1992 New approach: –Jan 1985 to Dec 2006 Issues: –Gaps in space and time –Approach: Filled gaps in time, then in space Pathfinder SST v5 Percent ‘low quality’ data 1985-2006

17. High Resolution Stress Indices CRW ‘Degree-Heating Weeks’ Degree Heating Weeks (DHW) calculated using HotSpots: DHWs = 0.5 * Summation of previous 24 twice-weekly HotSpots, where HotSpots have to be at least 1.0 °C to be accumulated.

18. Methods Degree Heating Weeks (DHW) was calculated using the HotSpots that we produced previously. – Calculations were done as implemented by NOAA. DHWs = 0.5 * Summation of previous 24 twice- weekly HotSpots, where HotSpots have to be at least 1.0 °C to be accumulated.

21. Cold Stress Index Corals have a lower temperature limit under which they are susceptible to stress and death Objective: –develop high spatial resolution cold-stress index to help monitor and forecast coral bleaching or mortality due to cold stress.

22. 2010 Florida Keys Case Study JAN 2010: Anomalously cold temperatures Widespread mortality in coral reefs SST observations helped guide a field survey 22 In situ temperatures

23. Developing a ‘Cold Snap’ Index Approach: Nighttime - only AVHRR Pathfinder (v5.0) SST data at a 4 km spatial resolution (no gap filling) used to create higher resolution climatologies from 1985 – 2006 23 Daily AVHRR Pathfinder SST (4 km – remapped to 1km) vs. daily USF daily SST (AVHRR 1 km LAC)

24. ‘So what?’ Linking science and management Ultimately, the goal is to improve our ability to alert reef managers around the world of bleaching-level stress, so they can take appropriate actions. In the Florida Keys, the CRW products have already helped: Guide Rapid Response efforts to assess reef conditions Inform the public about what may be happening on the reef when corals are visibly stressed
