Sea Level Research

Overview

Rising sea levels pose substantial risks to coastal populations, economies, infrastructure, and ecosystem services. Of the ~1 billion people worldwide living in low-elevation coastal zones ~70% are located in Asia. Improving our understanding of past and present sea-level changes is crucial in minimizing the effects of sea-level rise through appropriate coastal planning, adaptation, and mitigation strategies based on sound reasoning. This is complicated, however, because regional and local relative sea-level changes differ from the global mean due to a variety of driving mechanisms associated with vertical land motion, atmospheric and ocean dynamics, and tectonics. Understanding the impact of these mechanisms on past and present-day sea levels provides greater confidence in accurately quantifying their contribution to future sea-level projections and for better adaptation and management strategies.
