Influence of Coral Community Structure and Thermal Stress Exposure on Observed Patterns of Bleaching across the Northern Mariana Islands
Abstract
In 2013 and 2014, the Mariana Archipelago experienced consecutive thermal stress events that resulted in widespread coral bleaching and mortality. Using in situ survey data collected across seven of the Northern Mariana Islands during the 2014 event, we undertook the first quantitative comparison between the National Oceanic and Atmospheric Administration's Coral Reef Watch 5 km satellite monitoring products and coral bleaching observations. Analysis of coral community characteristics, historical temperature conditions and thermal stress revealed a strong influence of coral biodiversity in the patterns of observed bleaching. This illustrates the importance of using local benthic characteristics to interpret the level of impact from thermal stress exposure. In an era of continuing climate change, accurate monitoring of thermal stress and prediction of coral bleaching are essential for resource managers and stakeholders to direct resources to the most effective management actions to conserve coral reefs.
