The organizers of the conference are unable to allow us to organize a speaker session with formal presentations. Only a poster session with panel discussion and input from the floor will be allowed. Our intent was to include climatologists and physicists in this session, and we are unable to attract their participation to a poster session. We apologize for any inconvenience this may have created, and we would very much like to receive communications from anyone who was interested in participating in this symposium or who is working on this topic.

Please reply to him or A.E. Fallick at the addresses given below. --DS] Head of the NERC Radiocarbon Laboratory With the imminent retirement of Doug Harkness (October 1998) the University of Glasgow invites applications and nominations for the above position. The self-contained Laboratory unit (RCL) is hosted at the Scottish Universities Research and Reactor Center (SURRC) in East Kilbride and, as from 1st April 1998, is managed in tandem with the SURRC's other activities under the directorship of Professor A.E. Fallick. At present the RCL is equipped and staffed to match an annual throughput of 1,300 natural C-14 measurements (300 by radiometric counting plus 1,000 via the production of graphite targets that are subsequently monitored by Arizona or Lawrence Livermore). The RCL building is designed to allow a doubling of the AMS target preparation capacity and it also houses an isotope ratio mass spectrometry laboratory geared to 13C/12C, 18O/16O and 15N/14N natural abundance measurements. In terms of its science, the RCL has a primary remit to provide consultative and analytical support for research themes prioritised and funded by the Natural Environment Research Council (NERC). However, the pursuit of in-house research initiatives is regarded as an essential component of the RCL's overall agenda and the Laboratory enjoys an international reputation for its contribution to the general advancement of radiocarbon science. The successful candidate will be expected to provide the appropriate lead in maintaining and building on this level of peer recognition. Suitable candidates will have a PhD backed by a well attested record of academic attainment in the application of isotope geochemistry to aspects of environmental research and/or Quaternary reconstruction. Experience and a proven success in laboratory and project management is equally important. The combined academic and managerial responsibility will be recognised by an appointment at the Senior Lecturer level (in the salary range £29,968.00 to £33,868.00) and it shall be open to the Appointing Committee to recommend to the Principal that the successful candidate be considered for promotion to a Personal Professorship. This will be a fixed term appointment; the post has guaranteed funding for 5 years in the first instance and renewal thereafter will be subject to a peer assessment and the assignment of scientific priorities within NERC's overall funding regime. Specific queries concerning perceived scientific priorities and/or available analytical facilities should be addressed to: Dr D D Harkness Telephone: +44 (0) 1355 260037 Fax: +44 (0) 1335 229829 E-mail: DDH@wpo.nerc.ac.uk or Professor A E Fallick Telephone: +44 (0) 1335 270139 Fax: +44 (0) 1355 229898 E-mail: T.Fallick@surrc.gla.ac.uk ========================================================================= Date: Mon, 10 Aug 1998 10:52:20 -0700 Reply-To: mnadeau@leibniz.uni-kiel.de Sender: Radiocarbon Mailing List From: David Sewell Subject: AMS Postdocs at Leibniz-Labor, Kiel Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit [Forwarded on behalf of the Leibniz Labor; please reply to the addresses given at the end of the message. --DS] POSITIONS AVAILABLE Junior-Scientist / Leibniz Labor, Christian Albrechts University, Kiel, Germany The Leibniz Labor for Radiometric Dating and Isotope Research invites applications for two postdoctoral positions in the Accelerator Mass Spectrometry (AMS) Group in a) physics and b) (geo/bio) chemistry. The Leibniz Labor is largely funded by measurement income. The AMS group uses, since 1996, a 3 MV Tandetron accelerator system as an ultrasensitive mass spectrometer for radiocarbon (14C/C down to 10-15). The study of other rare isotopes is planned. The group has already made contributions to fields such as palaeoclimatology, oceanography, geology, archaeology, and art history. The successful applicant(s) will take part in the AMS operations, i.e. measurement of samples, quality control and evaluation of results, and maintenance of the AMS system. Furthermore, depending on qualifications, in one or more of the following: (i) the development of ion-optics, electronics, ion sources, analyzing-systems for AMS, (ii) the development of new sample materials and applications for the use of AMS of 14C and other isotopes; this includes responsibility for routine sample preparation, and (iii) the use of mass spectrometry of carbon and oxygen, in conjunction with AMS, in environmental studies. Candidates should have a PhD in a) (nuclear/small accelerator) physics with a good knowledge of ion optics, vacuum techniques, computer programming, and electronics or in b) (geo/bio) chemistry, applying chemical and/or isotope techniques in environmental sciences. They should be familiar with computers (PC, Windows) i.e. data reduction and analysis and databases; knowledge of English and German is preferred. The successful applicant(s) will be part of an internationally-oriented team dealing with all aspects of AMS. A flexible work schedule, including occasional work during weekends, is required. The position(s) will be awarded initially for one year, and may be renewed up to 3 years. Salary will be commensurate with experience. Send a resume, including a 1-page statement of research interests (in English), a copy of your most important publication(s), names and addresses of 3 references, and other relevant documentation to Prof. Pieter Grootes, Leibniz Labor, Christian Albrecht University, Max Eyth Str. 11, 24118 Kiel, Germany (tel. 0049-431-880-3894).

In-Reply-To: <19980831092909.A14494@packrat.aml.arizona.edu> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" David Sewell brings up an important problem - the dispostion of records from defunct radiocarbon labs. As coordinator of the North American Pollen Database, I've contacted radiocarbon labs a number of times to sort out problems, such as different dates reported for the same lab number in different publications, etc. In one case I found the now retired proprietor of the lab, who said she was just about to throw the records out. It would be valuable if some long-term institution were to take on the task of archiving these orphaned records, which do remain valuable.
