abstracts



All posters will be displayed for the entire length of the YSM.
Note: Participants selected to give talks will not present posters.

poster size

Your poster should fit within a 1.2 m x 1.2 m (4' x 4') space. The international standard A0 size (841 mm × 1189 mm) will fit. For USA and Canada, this is equivalent to ANSI E size (34'' x 44'').
Poster pins will be provided.

If you are attending the OSM, you may use the same poster for that meeting.

poster sessions

The eight YSM poster sessions are organized into groups based on PAGES science structure. Each of the poster sessions covers science highlighted by the Foci or Cross Cutting Themes (CCTs).

poster session 1 & 2 – Monday, 6 July

session 1: Climate Forcings (PAGES Focus 1)
This session invites contributions towards a quantitative understanding of the nature, causes and impacts of variations in climate forcings, including primary and secondary as well as natural and anthropogenic (e.g., including solar insolation and irradiance intensity, volcanic activity, land cover, sea ice, and greenhouse gas and aerosol concentrations). Research presented in this session provides either improved, extended, and consistent time series of climate forcing parameters or concepts or model results on the causes and impacts of forcings and feedbacks.

session 3: Chronology (PAGES CCT 1)
Chronology is crucial to paleoresearch and often constrains the strength of conclusions based on paleo-reconstructions. This session invites contributions that improve tools for absolute and relative dating, enhances the reliability of reference timescales, and explores creative new approaches to solving chronology issues.

session 4: Proxy Development, Calibration & Validation (PAGES CCT 2)
This session invites contributions that improve the precision and accuracy of paleo-proxies as a basis for high-quality records and reconstructions of past global change to complement instrumental data. It includes efforts on proxy interpretation and development, analytical innovation, inter-laboratory comparisons, and calibration refinement, which lead to uncertainty reduction in proxy-based reconstructions.

session 5: Modeling (PAGES CCT 3)
Numerical models provide a comprehensive framework for exploring couplings and feedbacks between the various components of the Earth System, and as such, modeling is a key element in paleoresearch. This session hosts efforts that improve model components specific for paleoscientific applications, which are generally not as relevant to the communities developing Earth System models for future projections.

Contributions can cover a wide range of topics, including database structures, data compilation projects, data visualization tools, etc.

poster session 7 & 8 – Tuesday, 7 July

session 7: Global-Scale Earth System Dynamics (PAGES Focus 3)
This session looks at interactions between components of the Earth System (atmosphere, biosphere, cryosphere, hydrosphere) and at the links between regional- and global-scale changes. It addresses the processes underlying global-scale changes, including the response to changes in forcings, internal feedbacks and teleconnections. Activities aim to synthesize records of the hydrological cycle, ocean biogeochemistry, interglacial variability or major rapid climate change at a global scale.

session 8: Human-Climate-Ecosystem (PAGES Focus 4)
This session addresses the long-term interactions among past climate conditions, ecological processes and human activities. It calls for data and modeling studies that aim to better understand the nature of these interactions, to quantify the roles of different natural and anthropogenic drivers in forcing environmental change, and to examine the feedbacks between anthropogenic activity and the natural system. Emphasis lies in comparing regional-scale studies of environmental and climatic processes using or combining computer models and natural archives, documentary and instrumental data.
