Using ecological and chronological data to improve proxy-based paleo sea level reconstructions
Venue Trinity College, Dublin
Workshop organisers: Natasha Barlow (University of Leeds), Robin Edwards (Trinity College, Dublin)
Scientific rationale The first meeting of the new phase (2019-2021) of the PAGES and INQUA working group PALeo constraints on SEA level rise (PALSEA) will focus on refining proxy-based reconstructions of past sea level. Sea-level rise due to polar ice sheet decay in a warming world is one of the most important, and most uncertain aspects associated with climate change. Because the instrumental record is short and changes to date have been modest, observations from the recent past provide at best a limited vantage point from which to gauge the future. The geologic record, in contrast, features major, and sometimes rapid, changes in ice sheets and sea level that remain to be fully explored and explained. Recent methodological improvements bear the potential to reduce uncertainties in local sea-level reconstructions, which will be crucial for reconciling sea level-based estimates of past ice sheet volumes.
Program The meeting will run over 3 days:
Day 1 (July 21st) will be dedicated to the ecological and environmental interpretation of proxy-based datasets.
Day 2 (July 22nd) will focus on cutting-edge chronological attribution techniques, which is critical to link sea level data to climate archives in order to better understand the drivers of change.
During day 3 (July 23rd) the participants will be split in two separate groups, each working on one specific time period, to refine reconstructions and database protocols based upon the discussions from the previous days. One group will focus on the Holocene, coordinated by the HOLSEA (an INQUA working group) leader Nicole Khan, while the second group led by Alessio Rovere will work towards the inception of the World Atlas of Last Interglacial Shorelines.
A full meeting program will be circulated to delegates in May.
Abstract submission and registration Abstract submission and registration has now closed. Please note delegates are responsible for booking their own accommodation in Dublin. Some additional support for ECR's may be available (in addition to the wavered registration fee) following the meeting. Please keep copies of original receipts and we will make those who are eligible aware, if funding allows.
