Description:"During the latter half of 1998, Palau experienced unprecedented bleaching that resulted in significant mortality and the loss of significant proportions of one of the few remaining pristine coral reefs in the world. Prior to 1998 and since 1998, little to no coral bleaching has been observed. These observations were consistent with data from the National Oceanic and Atmospheric Administration (NOAA) Coral Reef Watch (CRW) satellite Degree Heating Week (DHW) product. The DHW satellite product clearly shows that the 1998 accumulated thermal stress easily surpassed the critical DHW equals 4 threshold for coral bleaching and is the only year to have done so since 1985. This is consistent with field observations of bleaching. The Nature Conservancy (TNC) and the Palau Government joined forces to design and implement a protected areas network (PAN) for Palau's coral reef ecosystem. A PAN is best described as a series of marine protected areas (MPAs). They recognized bleaching as being potentially one of the major future threats to the Palau coral reef ecosystem. However, with only one poorly documented bleaching event on record, it is difficult to gain enough experience to be able to build resilience to these events into the PAN. In parallel with this effort to design a PAN for Palau, NOAA and the Australian Institute of Marine Science (AIMS) were collaborating on the use of hydrodynamic models to predict heat stress during a bleaching event. In 2003, it was decided to combine these efforts and for NOAA and AIMS to produce a heat stress model for Palau for use in the PAN planning as an attempt to identify factors that might confer resilience to climate change"--Executive summary.
