REPORTS OF REPRESENTATIVES ON
INTER-UNION COMMISSIONS

Report for the period 1991-1995 on the
Inter-Union Commission on the Lithosphere (ICL)

Soren Gregersen, IUGG representative in ICL

The ICL is an activity with IUGG and IUGS, our sister Union in geology, as equal partners. It runs the International Lithosphere Program (ILP), which since the reconstruction in 1990, has consisted of time-limited projects. I enclose an overview of these, made by the Secretary General of ICL, Dr. Michael Berry. Some projects have come to an end in the report period, either because they were successfully concluded or because the activity was not needed or not functioning satisfactorily. This set-up of the ILP has just been reviewed positively by ICSU. And IUGS has likewise recommended its continuation. In the Association Presidents meeting with the IUGG Bureau last year in Boulder, this project organisation was discussed with the ICL President, Professor Kevin Burke, and its continuation was recommended. So the ICL is ready for another 5-year term beginning in 1995, with the structure given by the overview schedule, and with considerations of terminating some of the projects and starting others as need arises.

The ICL is managed by a Bureau of 7 scientists:

President and Secretary General plus 1 member appointed by the two unions IUGG and IUGS in agreement, 2 members appointed by IUGG, and 2 members appointed by IUGS. In the period 1990-1995 the President has been a geologist, Professor A.W. Bally until 1992, and from then Professor Kevin Burke. The Secretary General has been a geophysicist, Dr. Michael Berry, who has done an excellent job for IUGG in this capacity. The common appointee has been Professor F. Barberi, who was in 1994 replaced by Professor Ross Taylor. IUGG has appointed B. Romanovicz, who was in 1992 replaced by T. Sasao. The other IUGG appointee has been Alexei Gvishiani, replaced in 1992 by Stephan Sobolev.

The proposals for these positions for the new 5-year term, beginning with the Boulder General Assembly of IUGG are:

President: Professor Alan Green, Zurich,

Secretary General: Professor Jörg Erzinger (geologist), Potsdam,

and new member to replace T. Sasao, Dr. Teruyuki Kato, Tokyo.

Dr. Stephan Sobolev and Professor Ross Taylor may continue at least until next year.

Three scientists have been appointed by their Associations to be liaison scientists to ICL and to me as the IUGG representative to ICL

IAGA: Professor Sven-Erik Hjelt, Oulu,

IASPEI: Professor Stephan Müller, Zurich,

IAG: Dr. Peter Wilson, Potsdam.

During the IUGG General Assembly in Boulder this summer the ICL Bureau and Commission will hold their annual meetings, in which I will participate. And I will meet with as many representatives of our Associations as possible. ICL cosponsors many of the symposia in Boulder, so they do have an impact on our General Assembly.
