This dataset consists of raster geotiff outputs of relative environmental favorability for coral growth and survival in the United States territories of Guam and American Samoa across 3 climate scenarios: Present, Intermediate Emissions (Representative Concentration Pathway 4.5), and Worst Case Emissions (Representative Concentration Pathway 4.5). These datasets were generated from a synthesis of spatial variability in many environmental conditions, including thermal stress, wave power, irradiance, chlorophyll concentrations, macroalgal cover, calcite concentrations, turbidity, and erosion. Input conditions were classified as “Managed” or “Non-managed” based on whether the condition could be managed at the island scale. Environmental favorability scores range from 0 to 1, with 0 representing the worst observed conditions for coral and 1 representing the best observed conditions within each territory and scenario. The full methods and results are described in detail in the parent manuscript, “Where favorable environmental conditions and resilient corals coincide: Guam and American Samoa” (2022).
