It's on pp. 12-13 of the bulletin, with the text also available at http://www.wisc.edu/anthropology/sas/201O.htm One correction to the discussion of RADIOCARBON's site: the separate online publication RADIOCARBON DATE LISTS, issued in 1995 and 1996, has been discontinued. Date lists have been re-integrated into regular issues of RADIOCARBON (and in fact we republished the RDL date lists in Volume 39, No. 1, 1997). Traditional laboratory date lists may be a fading genre, with the huge number of dates being produced especially by AMS labs, but we still encourage their submission, particularly in the form of annotated lists useful to researchers in a given geographical area or chronological period.

We used a 99.9999% pure varity supplied by AESAR, and then went to a 99.995% pure variety with no degredation in results when they stopped producing the 99.9999% zinc. Now AESAR only stocks a 99.5% purity zinc powder. The mesh size has also changed from -100 - +200 to -150 - +350. We have tried other usual chemical suppliers (e.g. Aldrich, etc.) for zinc, but nobody stocks high-purity zinc. Does anybody know of a source for high-purity zinc, and/or does anybody else who uses zinc powder in the graphitzation stage for target preparation have experience with this lower grade of zinc? I can certainly run some of my own tests, but it would save time if somebody knows of alternative sources or zinc types. Thanks, Brian Haskell -- _/ _/_/_/ _/_/ Dr. Brian J.

Our group has been using 99.99% manganese "powder" (small chunks between -8+20 mesh) from AESAR. Because of the high melting point of Mn, and its negligible vapor pressure at reduction temperatures (550 to 650 deg. C), we can perform the graphite reductions in quartz tubes isothermally (one pot "batch" process in a furnace) without contaminating the AMS targets with reductant. If you wish, I can send you a preprint of our paper describing the technique.

The conference organizers list these workshop goals: Evaluate the spectrum of PAGES science activities and tasks from the perspective of well-coordinated data management and full and open sharing of scientific data. Data management encompasses the technical details of how PAGES data sets are processed, documented, archived and distributed, whereas data sharing focuses on the ease of timely availability and usefulness both of data required to actually carry out the scientific research and data generated as a result of the scientific research. A challenge within the PAGES science activities and tasks is to ensure end-to-end data management and data access while maintaining the emphasis on basic scientific research questions. The systematic evaluation of the PAGES activities and tasks will provide a mechanism to identify common problems and to develop crosscutting solutions to overcome potential roadblocks. The resulting workshop report will describe how needed data management and access can be unobtrusively integrated into the PAGES science activities and tasks, and present an implementation plan for the next five years. Among the crosscutting issues alluded to will be improved chronologies and correlations for these different projects.
