Abstract
Motivation
Timing, duration and severity of marine heatwaves are changing rapidly in response to anthropogenic climate change, thereby increasing the frequency of coral bleaching events. Mass coral bleaching events result from cumulative heat stress, which is commonly quantified through degree heating weeks (DHW). Here we introduce CoralBleachRisk, a daily-resolution global dataset that characterises sea surface temperatures, heat stress anomalies and the timing, duration and magnitude of severe coral bleaching conditions from the recent past (1985) to the future (2100) under three contrasting Shared Socioeconomic Pathways. Our projections are downscaled to a 0.5° resolution (~50 km), bias-corrected and validated using remotely sensed data of sea surface temperatures and a global dataset of historical coral bleaching events. An accompanying online software tool allows non-specialist users to access aggregated metrics of coral bleaching risk and generate time series projections of coral vulnerability for Earth's coral reefs. Our dataset enables regional to global comparisons of future trends in severe coral bleaching risk.
Main Types of Variables Contained
Sea surface temperature (SST), SST anomaly, DHW, annual timing and duration of Bleaching Alerts.
期刊介绍：
Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
