Dear Colleagues,
       Dan Sinclair and I are organizing a session at the June, 2008 ASLO
Summer meeting in St. John's, Newfoundland on the sclerochronology and
biogeochemistry of cold-water corals (full description below). We would like
to encourage you to submit an abstract, and would appreciate your help in
spreading the word to students and colleagues. We hope to see you in St.
Best wishes,

Session description:
Sclerochronology and biogeochemistry of cold-water corals
Chairs: Owen Sherwood, Daniel Sinclair

Interest in the paleoceanographic utility of cold-water corals continues to
grow. From its infancy over a decade ago, the science of
paleo-reconstruction has evolved in two principal directions. Single
long-lived Gorgonians promise continuous high-resolution records over
century to millennial time scales. In contrast, cores taken down through
deep reefs yield fragments of Scleractinian corals that may contain
snapshots of seasonal-resolution climate over millions of years.

However, development of useful climate records from either approach proves
challenging. Isotope and element 'vital effects' are ubiquitous in
cold-water scleractinians; can we extract meaningful environmental records
in light of this? How do we interpret the isotopic and elemental composition
in the 2-part mineral-organic skeletons of cold-water gorgonians? Are
geochemical records reliable and reproducible, and are they diagenetically
stable? What are the best techniques for developing accurate age models? How
do we calibrate records given the paucity of in-situ data in the deep ocean?
The purpose of this session is to provide a forum for the presentation of
results that explore all aspects of sclerochronology and biogeochemistry of
cold-water corals.
