Dear List members,

AGU Fall Meeting 2012: "Insights to the Modern and Palaeo Carbon Cycle: Isotopic and Bio= marker Perspectives=94 (session B035 )

We invite you to submit abstracts to = the above session, run in conjunction with the "Development of Is= otopic Proxies for Palaeoenvironmental Interpretation: A= Carbon Perspective" (DIPPI -C) working group, at this years AGU Fall Meeting in San Franc= isco (3rd - 7th December). Associated with the DIPPI -C workin= g group and this AGU session is a special theme in the AGU and Geochemical So= ciety Journal Geochemistry, Geophysics, Geosystems = (G-Cubed) which is currently open for manuscript submission for researc= h related to this session (i.e. C cycle processes at a range of spatial and temporal scales using organic and inorg= anic carbon geochemistry)[for more info - http://www.agu.org/journals/gc/theme.shtml?collectionCode=3DCARBON1&jou= rnalCode=3DGC].

Chris Brodie (The = University of Hong Kong, Hong Kong SAR)

Phil Meyers (The University of Michig= an, USA)

James Casford (Dur= ham University, UK)

Jesper Olsen (Aarhus University, Denmark)=

Session description:

Understanding the carbon (C) cycle is central to constraining environm= ental processes from biological productivity through to palaeoenvironm= ental interpretation. Quantifying these processes at differen= t spatial and temporal scales requires an integrative inter-disciplinary approach incorporating both organic and = inorganic C. This session aims to bring together researchers that use bulk = and compound specific =E413C , =C414C and b= iomarker distributions in marine and terrestrial, modern and palaeo environments. We encourage contributi= ons investigating biological productivity; short- and long-term C fluxes; d= iagenesis , preservation and soil processes; C cycling in= modern and palaeo -environments; and method development.

Invited presenters:

Prof. Peter Swart (The Univeristy<= a> of Miami, USA)

Prof. Katherine Freeman (Pennsylvania S= tate University, USA)

[More presenters to be announ= ced shortly]

An= nouncement

RA= DIOCARBON LABORATORY QUALITY ASSURANCE PROGRAMME (SIRI)

The issue of comparability of measur= ements (and ultimately bias, accuracy and precision of measurement) is one = which has been the focus of some attention both within the ¹⁴C community and the wider user communities. The des= ign and organisation for the sixth (SIRI) radiocarbon laboratory inter-comp= arison is intended to complement and extend previous radiocarbon international quality assurance programmes run success= fully by Glasgow University and SUERC, most recently TIRI (1991 – 199= 5), FIRI (1997 – 2002), and VIRI (2004 – 2008) (Scott 2003; Sc= ott et al, 2010a,b).

The aims and objectives of SIRI are:=

to demonstrate the comparability of routine analyses carried out in rad= iocarbon laboratories
to quantify the extent and sources of variati= on in results
through choice of material to contribute to the discu= ssion concerning laboratory offsets and error multipliers in the context of= IntCal (the International Calibration Programme).
to gain a better= understanding of differences in background derived from a range of infinit= e age material types

SIRI will be a single stage proficie= ncy trial, lasting approximately 2.5 years. Samples will include a se= quence of tree rings, and several background samples suitable for AMS analysis. While it will not be possible to provide t= he same samples for radiometric laboratories, a small, distinct set of samp= les will be available for LSC and GPC laboratories.

Samples will be distributed in early= 2013.

If you wish to participate or wish f= urther information, please send your contact details to marian.scott@glasgow.ac.= uk.
