Project Overview

Projections of future RSL change can be improved with a better understanding of how RSL has changed since the Last Glacial Maximum (LGM). Regional sea-level databases are effective tools for showing the magnitude, rate, spatial variability, and driving mechanisms of past RSL. Trends contained within the datasets can also provide information on the timing and contribution of past ice sheets to GMSL since the LGM. In conjunction with GIA modelling, databases can constrain key components of RSL change during the Holocene. We follow the standardized procedures, established by the HOLSEA working group, to develop databases for key regions. We are producing databases for key regions, which include Southeast Asia, the Indian Ocean, Pacific Ocean, Belize, and the Russian Arctic. These databases include a combination of existing revaluated data, as well as previously unpublished datasets, and will be used to address the following research questions:

  • How has RSL changed since the LGM?
  • What were the relative contributions from past ice sheets to RSL since the LGM?
  • What are the key mechanisms driving the spatial variability in RSL change during the Holocene?
