The PAGES-PMIP Working Group on Quaternary Interglacials (QUIGS) workshop, titled "Interglacials of the 41kyr-world and of the Middle Pleistocene", will be held in Molyvos, Greece, from 28-30 August 2017.

Venue

Delfinia Hotel, Molyvos, Island of Lesvos, Greece.

Logistics

The number of participants to this workshop will be limited to 30. In addition to invited participants, there will be open spaces for interested scientists with a track record of working on the topic.

Overview

Our understanding of glacial-interglacial cycles has been built on a large body of evidence on Middle and Late Pleistocene environments, dominated by 100kyr ice-volume variations. However, any theory of ice ages remains incomplete if it does not include an adequate description and understanding of the mode and tempo of climate variability during the 41kyr-world and the transition into the 100kyr-world (the so-called [Early] Middle Pleistocene Transition, MPT).

This will be the third workshop of QUIGS first phase. Phase 1 aims to formulate research questions, identify knowledge gaps and steps how to fill these gaps. In close collaboration with PMIP, QUIGS1 defines model protocols and initiates the model runs and data collection needed. Phase 2 will attempt to systematically answer the research questions on the basis of model runs and data compiled during the intervening period.

Workshop aims

Our aim will be to examine whether there are any fundamental differences between interglacials of the 41kyr- and 100kyr-worlds:

- Does the distinction between 'saw-toothed'-shaped glacial cycles of the 100kyr-world and more 'symmetric' cycles of the 41kyr-world reflect the influence of ice-sheet size?
- What was the duration of interglacials of the 41kyr-world?
- Does the association of bipolar seesaw variability with glacial Terminations extend into the 41kyr-world?
- How did the intensity and shape of integlacials change during the MPT?
- What were the underlying causes of the MPT?

Some of these questions could begin to be addressed by existing or currently generated datasets. Providing a detailed reconstruction of the structure of 41kyr cycles, the sequence of events at glacial Terminations and an assessment of the role of the bipolar seesaw in promoting deglaciation would represent significant contributions to initiate model runs of Early Pleistocene glacial cycles.

Expressions of interest

The deadline for expressions of interest to attend this meeting is 10 March. Expressions of interest should be sent to Chronis Tzedakis (This email address is being protected from spambots. You need JavaScript enabled to view it.) and Emilie Capron (This email address is being protected from spambots. You need JavaScript enabled to view it.) with a short description of research experience on the topic. A track record on Early Pleistocene 41-kyr world and the Middle Pleistocene Transition is essential. Notifications will be sent by the end of March.

Financial support

A limited amount of funding is available for early-career researchers and/or scientists from developing countries. Please state in your expression of interest the reason/s financial support is required.
