Abstract
Phasing of ice-sheet and sea-level responses to past climate change
Highlights
The five-day program included 29 presentations, several group discussions, a poster session, and field excursions to fossil reefs at Xcaret and limestone caves at Rio Secreto
Participants examined the quantification of uncertainty due to glacial isostatic adjustment (GIA) on global sea-level signals in order to reconcile peak Last Interglacial (LIG) sea-level reconstructions
Suggestions included targeting near-to-intermediate field regions sensitive to GIA, such as the Bahamas, to limit possible ice-sheet configurations, developing adjoint framework methods to efficiently estimate GIA-model parameters, and applying 3D GIA Earth models to investigate model error associated with lateral viscosity variations
Summary
The five-day program (http://pastglobalchanges.org/ini/wg/palsea2/meetings/127/1715) included 29 presentations, several group discussions, a poster session, and field excursions to fossil reefs at Xcaret and limestone caves at Rio Secreto. Participants examined the quantification of uncertainty due to glacial isostatic adjustment (GIA) on global sea-level signals in order to reconcile peak LIG sea-level reconstructions. Discussions focused on GIA uncertainty stemming from ice-sheet configurations and 3D Earth-model parameters, as well as the need for additional paleo sea-level data.
