Description:
Abstract:
Chronology and time-series geochemistry data of a coral core collected from Olowalu, West Maui, Hawaii. The chronology is based on density banding, radiocarbon bomb-curve, and uranium thorium dating techniques. The geochemistry time-series data contains major and minor elements over the length of the coral life span, as measured from laser ablation inductively coupled mass spectrometry (LA-ICP-MS).
Purpose:
Erosion and associated sedimentation are the most significant threats to Hawaii's terrestrial and marine resources. Given that regional-scale resilience of coral reefs to global climate change may be significantly influence by local water quality, there is the potential that compounding stressors will reduce the tolerance of corals to climate change perturbations. The Coral Reef Working Group (CRWG), made up of key state and federal partners involved in coral reef management, has identified Olowalu as a Hawaii Coral Reef Strategy Priority Site and adjacent to a proposed priority watershed. This information is valuable for resource managers in Hawaii trying to calculate trajectories of coral reef health related to future land-use and climate change, since both processes will affect the supply and storage of sediment to the reef flat.
