Project Goals
To inform projections of sea-level rise in response to future climate change, this project aims to address two fundamental questions:
- How did global mean sea level (GMSL) change since the Last Glacial Maximum (LGM) and what were the contributions of the Greenland and Antarctic ice sheets and temperature-driven variations?
- What were the trends, magnitudes, and driving mechanisms of spatial variability in relative sea level (RSL) during this period?
Methodology
To answer these questions, we will:
- Produce the first spatially-comprehensive, standardized global compilation of geological relative sea-level reconstructions from the LGM to present.
- Incorporate the geological data into hierarchical statistical models to address our research questions and make projections of spatial variability of RSL for regional scenarios of future sea-level rise.
- Distribute the global dataset to the glacial isostatic adjustment modeling community to provide a high-quality standard for model tuning and optimization.
The database and model outputs will be made freely available on a web-based platform and will provide a much-needed resource to the paleoclimate community.
HOLSEA meetings have attracted over 70 scientists from 20 countries on the North American, European, African and Asian continents, including Australia and New Zealand.
