We are therefore trying to track down any existing information on previous cases in which herbicides have been broadly applied on archaeological soils, in particular any research regarding potential effects of herbicides to analytical processes like radiocarbon dating, and/or any research that may have led to a recommendation for or against any particular herbicidal product. Would appreciate hearing if any of you are aware of published or otherwise available information along these lines. Thank you.

The palaeoclimate data base integrated in CALPAL presently contains some 60 climate proxies, mainly from the polar and equatorial ice-cores. Another incentive is to explore data & methods applicable to the Glacial extension of the 14C-calibration curve. CALPAL is now in the 2001 "Ghost of Edinburgh" edition, which supports 14C-age conversion back to 50 ka 14C-BP. The climate database covers 500 ka. Our application of CALPAL is in studying human/geo/environmental events and processes in relation to climate change. CALPAL runs on PC under the operating systems WIN9x/NT/2000. The package requires c. 20 MByte free storage on a hard-disk drive named c:/ and a 200 MHz 586 Processor or faster. CALPAL is free-of-charge for the scientific community Have a nice time in the World of Glacial Radiocarbon Calibration !

I try to take samples from well-preserved, compact bones which contain a good amount of collagen. In several cases, however, bones are badly conserved, highly fragmented and corroded (and charcoal unavailable as alternative). My question concerns the influence of bone conservation on C14 dating.(I mean conservation due to the geological context of the bones, not the influence of agents such as glues etc.) Could someone help me with his experiences or references to the literature?

Scientists will share responsibilities for routine and experimental work, liaison with the user community, collaborative and in-house research, facility development, and administrative duties as required. This will require a strong commitment to collaborative research, a flexible attitude to duties and good interpersonal skills. Applicants with a relevant PhD and postdoctoral experience, or similar, in some or all of the following would be preferred: AMS or similar isotope ratio mass spectrometry and their applications; accelerator or experimental nuclear physics; analytical chemistry; quality control and project management. Appointees to RA2 are expected to take the initiative in research and development, including independent work and significant responsibility for collaborator interaction and training at a supervisory level as necessary. The posts are available for three years in the first instance, although the project is considered long-term in nature. Successful applicants should be available in time for instrument tests in the USA in March 2002. Details are available at http://www.gla.ac.uk/suerc/AMS/.

Switsur" Subject: Catalyst MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Dear Colleagues, I write to obtain help with a problem. This lab is based on scintillation counting of benzene synthesised from the sample carbon. In this acetylene is trimerized to benzene using a catalyst. We have successfully used the Perlcatalysator D1 suplied by Kali-Chemie from Hannover in Germany. We are now very short of catalyst and wish to order more. Does anyone know where we may get further supplies of this catalyst ? We get no reply from the address in Hannover. Failing this are there any other suppliers of the catalyst that we could try. What catalysts are used by other laboratories and can you let me have their address and prices ? Many thanks, Roy Switsur, Radiocarbon Dating Research Laboratory, East Road, Cambridge.
