The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | NOAA Coral Reef Watch Operational Near-real-time Twice-weekly Global 50 km Satellite Coral Bleaching Thermal Stress Monitoring Product Suite from 2009-12-31 to 2010-12-30 (NODC Accession 0075824) |
| Abstract: | NOAA's polar-orbiting satellites measure SST around the globe in near-real-time, and Coral Reef Watch produces a suite of products derived from this set of satellite SST and uses them to pinpoint areas around the world where corals are at risk for bleaching. This is a suite of operational products produced at 0.5 degree (approximately 50 km) spatial resolution twice-weekly. The products include nighttime sea surface temperature, nighttime sea surface temperature anomaly, coral bleaching HotSpots, and Degree Heating Weeks for the global oceans. |

| Supplementary information: | Coral Reef Watch's satellite coral bleaching monitoring and assessment products for archive include SST, SST anomalies, coral bleaching HotSpots, and coral bleaching Degree Heating Weeks. These products are produced by Coral Reef Watch in near-real-time using NOAA/NESDIS operational composite nighttime POES AVHRR SSTs at 0.5-degree spatial resolution. NOAA POES AVHRR Global Area Coverage (GAC) SST nighttime observations are used to generate Coral Reef Watch's global twice-weekly SST analysis product. This SST analysis is then used with Coral Reef Watch operational SST climatologies and coral bleaching SST threshold climatology to derive SST anomalies, HotSpots, and Degree Heating Weeks. The products are updated twice-weekly on every Monday morning (using AVHRR SST observations from the previous Monday through Wednesday), U.S. Eastern Time. Coral Reef Watch relies on the ethics and integrity of the user to ensure that the source of these data and products is appropriately cited and credited. When using these data, credit and courtesy should be given to "NOAA Coral Reef Watch." Data layers included in the data files: Data Layer Definition Type Dimensions (RxC) CRW_SST Twice-weekly global 50km satellite int16 331x720 nighttime sea surface temperature CRW_SSTANOMALY Twice-weekly global 50km satellite int16 331x720 nighttime sea surface temperature anomaly CRW_HOTSPOT Twice-weekly global 50km satellite int16 331x720 coral bleaching HotSpot CRW_DHW Twice-weekly global 50km satellite int16 331x720 coral bleaching Degree Heating Weeks surface_flag Pixel characteristics flag array uint8 331x720 Individual DHW, HotSpot, SST, and SST Anomaly HDF files contain two data layers including the corresponding data layer named in the table above (CRW_DHW, CRW_HOTSPOT, CRW_SST, or CRW_SSTANOMALY) and a surface_flag layer. Each of these files also contains an 8-bit raster image of the corresponding geophysical data layer contained in the file. The dimension of each image is 720 columns by 411 rows. Each image displays a data layer in its pre-defined color scale and the color legend is shown on each image. Corresponding color palette is attached on each image and extractable from the HDF file. An all-in-one file contains all the data layers listed in the table and their raster images with color palettes. All these data files are in HDF format, containing internally all the necessary information to understand and to properly use the data. Goreau, T.J. and R. Hayes, 1994.
