Dear Colleagues,
please find below the announcement of meeting to be held next year. I would
be grateful if could diffuse this announcement to all persons who, to your
knowledge, could be iinterested in attending the meeting.

International Workshop on the Isotope Effects in Evaporation: Revisiting
the Craig-Gordon Model Four Decades after its Formulation

to be held on 3-5 May 2006 at
Istituto di Geoscienze e Georisorse
Area della Ricerca del CNR
Via G. Moruzzi, 1 I-56124 Pisa, Italy

The aim of the Workshop is to re-examine the current knowledge for the
prediction and estimation of the isotope fractionations occurring during
phase changes of water in natural environments and laboratory experiments,
with special emphasis on the Craig-Gordon evaporation model.

The Workshop will include all topics related to the isotopic effects in
water evaporation and ice sublimation, vapour transport in the atmosphere,
vapour condensation, evapo-transpiration from plants and soils, as well as
experimental studies on exchange and isotope fractionations between ice,
liquid water and vapour, isotopic balance of lakes, isotopic records
associated with the evaporation-condensation cycle of water and their
relationships with the environmental conditions, etc. Also elements other
than hydrogen and oxygen, will be considered if they produce isotopic
effects related to evaporation or other phase changes of water.

The Workshop will include selected oral presentations and poster
presentations, whose extended abstracts should be submitted by January 31,
2006. The selection will be made by the scientific committee of the
Workshop. A web site will be established soon, where detailed information
on the meeting will be given.

The meeting is co-sponsored by the International Atomic Energy Agency, Vienna.

All those who are willing, or consider, to attend the workshop, are kindly
requested to express their interest to Roberto Gonfiantini, Istituto di
Geoscienze e Georisorse del CNR (E-mail

meeting programme and organization.

The Craig-Gordon evaporation model was formulated four decades ago and has
been, and still is, widely applied in isotope hydrology and geochemistry.
The model started to be elaborated by Prof. Harmon Craig during his 1963-64
sabbatical leave at the Laboratory for Nuclear Geology of the University of
Pisa, directed by Prof. Ezio Tongiorgi. The model was included in a long
paper on stable isotope variations in the ocean and the marine atmosphere,
co-authored by Louis I. Gordon. The paper was presented at the Workshop on
Stable Isotopes in Oceanographic Studies and Paleotemperatures held in
Spoleto, Italy, in July 1965, and published in the proceedings of the
meeting (Editor: E. Tongiorgi). In spite of the limited circulation of
these proceedings, the Craig-Gordon paper became rapidly a classic which
has made the history of isotope geochemistry,

Thus, the Workshop will also provide the opportunity to commemorate Harmon
Craig as prominent scientist whose research and ideas greatly contributed
to the advancement of the stable isotope geochemistry of light elements.
Together with him, we would like to remind the work of Ezio Tongiorgi, as
founder and promoter of isotope geology in Italy.
