[Aqualist] Two speleothem sessions at Fall AGU [SEC=UNOFFICIAL]

[TREBLE, Pauline]

Dear AQUA members,

Apologies for cross-postings.

There will be TWO speleothem sessions at the AGU Fall meeting this year. Both are highly relevant to the Australasian region.

UNRAVELING PAST HYDROCLIMATE IN THE TROPICAL INDO-PACIFIC AND AUSTRALASIAN MONSOON REGION:  NEW INSIGHTS FROM SPELEOTHEMS<https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session7402>

The Karst Record in Water-Limited Environments<https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session7485>


Fall AGU 14-18th December 2015 in San Francisco.

Abstract submission is now open. Deadline for abstracts is 5th August 2015.

Hope to see you there,

Pauline Treble, Michael Griffiths and Andy Baker.

Session ID#: 7402 Unravelling past hydroclimate in the tropical Indo-Pacific and Australasian monsoon region: New insights form speleothems

Session Description: The Australasian monsoon (AM), ITCZ, and Walker circulation (WC) play an integral role in modulating Earth’s climate via redistributing large amounts of heat and moisture. Gaining a clearer perspective on the full range and mechanisms of AM, ITCZ, and WC variability is critical to improved projections of regional and global climate change. Doing so, however, requires proxy records that are sensitive to rainfall and/or atmospheric circulation, and can be accurately and precisely dated. Speleothems possess these important attributes, and as such, have helped to answer some fundamental and longstanding questions in global change research. While much has been learned from East Asian speleothem records, significant spatial and temporal gaps exist over the broader region.  This session will highlight new and emerging speleothem records from the tropical Indo-Pacific and AM regions.  We encourage contributions focused on speleothem proxy development, model-data synthesis, and reconstruction of past hydroclimate variability in this key region.

Session ID#: 7485 The karst record in water-limited environments

Session Description:

Karst studies, and speleothem records in particular, have contributed greatly to key scientific datasets to advance our understanding of past climate and environmental change as well as diffuse recharge to groundwater. However, these datasets are dominated by studies from environments where annual precipitation exceeds evaporation, informing our current paradigm for speleothem interpretation.

It may be particularly important to obtain speleothem records from water-limited regions e.g. to build knowledge of drought frequency for water planning purposes. A significant portion of karst is located in environments where water may be permanently limited (arid to semi-arid regions), seasonally-limited (distinct dry season) or transient (drought-prone regions). Additional processes such as evaporation, transpiration and fire may challenge the interpretation of speleothem records from these regions. We invite contributions that advance our understanding of karst processes in water-limited environments, including: karst hydrology, cave monitoring, proxy development, model data, and speleothem records from these environments.
