Two PAGES working groups, PALeo constraints on SEA level rise 2 (PALSEA2) and PAGES-PMIP Working Group on Quaternary Interglacials (QUIGS), will conduct a joint, cross-cutting meeting from 24-27 September 2018 in Galloway, New Jersey, USA.

The meeting title is "Climate, ice sheets and sea level during past interglacial periods".

Venue

Stockton Seaview Hotel
Galloway, New Jersey, USA

Logistics

Participants will mostly be members of the PALSEA2 and QUIGS working groups, together with scientists interested in the cross-cutting theme, early-career researchers and scientists from developing nations. Up to 40 participants are expected.

Description

The overarching goal is to favor cross-cutting initiatives between members of these two communities. In fact, while workshops from these two projects (and their predecessors) were successful and produced a relevant number of products, the commingling of ideas between the two groups was mostly the result of individual initiatives, and few scientists participated regularly to the activities of both groups.

With this joint meeting, we aim to foster a more organized collaboration between PALSEA2 and QUIGS that is essential to solve a number of outstanding issues that have been identified by both working groups. These issues include:

- How do interglacial sea-level highstands relate to interglacial high-latitude, global and tropical temperatures?
- Is there a long-enough interglacial period with a relatively stable climate that one could argue an equilibrium ice-sheet volume is reached in response to climate/temperature forcing?
- Does the relationship between interglacial climate and ice sheets/sea level change across the Quaternary? Are there interglacials other than 5e and 11 where we could attempt to link climate and sea level?
- Can external (e.g. orbital) or internal (e.g. greenhouse gases) climate forcings explain the observed climate, ice-sheet and sea-level responses based on current knowledge of global physics?
- Can we reach a firm conclusion on the magnitude of warming and the maximum sea level contribution for Greenland and Antarctic in MIS 5e?

Program

This four-day workshop is divided in three main parts: the first two and a half days will be dedicated to talks and posters from the participants, divided in topical sessions. Each participant will be asked to tackle one of the main questions identified above or raise new ones related to both communities. The talk/poster sessions will be followed by a half day field trip to nearby salt-marshes (Holocene sea-level indicators) and the Pine Barrens (Late Pleistocene permafrost). The last day will be dedicated to (1) discussions focused on the cross-cutting themes between PALSEA2 and QUIGS and (2) the initiation of cross-cutting activities.

Key speakers/participants

The local organizer of the workshop will be Robert Kopp (Rutgers University). We are planning two keynote talks by PALSEA2 and QUIGS representatives. These talks will outline the lessons learned and the areas where cross-cutting collaborations are needed. Other speakers will be asked to give 30-minute talks providing a broad overview of central topics of interest for PALSEA2-QUIGS.

We foresee to have highlight talks related to paleo sea-level reconstructions (Jacqueline Austermann, Cambridge University, confirmed); paleo ice sheets; past warmer climates and paleo climate models.

Background

PALSEA2 and QUIGS-Phase 1 are coming to an end. While both working groups hope to return in some form, the idea for this workshop emerged from discussions between members of the two groups that highlighted the need for a joint forum to address the identified outstanding issues.

During the discussion sessions, each key issue will be addressed in the light of the presented talks and posters, additional cross-cutting themes might be identified and activities involving members from both PALSEA2 and QUIGS will be initiated.
