Both the Canadian National Committee for the IPA (CNC/IPA) and the Permafrost Subcommittee of the Associate Committee on Geotechnical Research (ACGR) met in November 1988. Permafrost activities in Canada over the past 12 months are summarized as follows:
At the Geological Association of Canada Annual Meeting in Montreal, Quebec, on May 16, 1989, a special session entitled "Massive Ground Ice: Delineation, geology and origin" was organized by F. A. Michel (Carleton University) and A. S. Judge
(Geological Survey of Canada). Fifteen papers were presented including several from Soviet participants. There were approximately 60 participants.
Following the annual meeting of the Canadian Geotechnical Society in Winnipeg, a workshop on Saline Permafrost was held at the University of Manitoba on October 26,1989. The workshop was sponsored jointly by the Permafrost Subcommittee and the Cold Regions Geotechnology Division of the Canadian Geotechnical-Society. The organizers were D. Sego (University of Alberta), T.H.W. Baker (National Research Council of Canada), P. Vidan (Government of the Northwest Territories). There
were approximately forty participants.
The Lanzhou lnstitute of Glaciology and Geocryology (LIGG) celebrated its 30th anniversary and hosted the Fourth Conference on Glaciology and Geocryology from October 5-9, 1988, in Lanzhou.
A total of 142 scientists from seven nations participated.The conference was broken into concurrent sessions on glaciology and permafrost. The topics discussed under glaciology included snowfall, glaciology, geomorphology, surging glaciers and
hydrology (particularly related to the glaciers of western China). The permafrost sessions dealt with periglacial landforms and processes, recharge of groundwater in permafrost regions, hydroengineering construction and the ecological environment in permafrost regions. Most papers dealt with studies in the Soviet Union and Canada, as well as glaciological studies in the Alps, also were presented.
Several key questions were discussed. One dealt with evidence for and against extensive glaciation of the Qinghai-Xizang (Tibetian) Plateau during the last glacial stage. The current estimates range from a 10% increase in ice cover to complete coverage of the plateau by an extensive ice sheet. Prof. Li Jijun from the Department of Geography of the Lanzhou University argued, based on geomorphic information, that the ice cover during the last glacial stage was about 10% greater than present. Another key issue is whether the plateau was cold and dry or cold and wet during the last glacial stage. The latter condition would allow for greater growth of glaciers. The clear message from these discussions is the need for more research with better time control.

We are pleased to welcome Denmark as the newest member of our association. On 18 October 1988 Denmark applied for membership with the Danish Society for Arctic Technology (SAT) as the Adhering Body. SAT was established in 1985 with the objective of creating an interdisciplinary contact between individuals and companies with knowledge and interest in cold regions
technology. SAT has 200 individual members and 35 company members. The officers of SAT are as follows:
Mr. Gunnar P. Rosendahl, Director, Nuna-Tek (formerly Greenland Technical Organization, GTO)
Mr. Henrik Mai, Managing Director, Arctic Consultant Group
Mr. Thorkild Thornsen, M.Sc., Nuna-Tek Surveys.
The application of Denmark for membership was approved by mail ballot of Council Members and has been eonfirmed by a general meeting of SAT. The Board of SAT has approved that Denmark pay dues of $250 per year in Group 3.
The Finnish Geotechnical Society sponsored the International Symposium on Frost in Geotechnical Engineering on March 13-15,1989, in Saariselka, Finland. Approximately 150 researchers from around the world attended. Three sessions were
held, including special lectures on the mechanics of freezing and thawing by B. Ladanyi, the frost heave properties of soils by D.M. Anderson, and frost protection in design and construction by R. Nordal. Other lectures were:
- Simulation of freezing and thawing of soil materials by E.A. Bondarev
- Frost problems in road construction by H. Brand1
- Modeling of thermal soil behavior by M. Fremond
- Frost susceptibility of soils by H. Jessberger
- Frost protection of design and construction in Japan by F. Kohno
- Preventative measures against frost action in soils by S. Kinosita
- Freezing and thawing in cylindrical coordinates by V.J. Lunardini
- Preventative measures against frost action in soils by A. Phukan
- Evaluation of frost heave properties of soils by S. Saarelainen
- Adfreeze strength of soils by A.V. Sadovsky
- Physical changes in clay due to frost action and their effects on engineering structures by E. Chamberlain.
52 related papers were presented and discussed and were published in two volumes, available from Technical Research Center of Finland. Following the symposium there was a two-day field trip to observe roads and road construction techniques
in Lapland. Methods of dealing with road icings, cracking and snow drifting were examined. The next symposium is scheduled for Anchorage, Alaska in 1993.

At the Council Meeting of 2 August 1988, France's application for membership was approved by unanimous vote. The IPA welcomes France as a member. The French Permafrost Association was formed on 22 April 1988.
The Executive Committee is composed of:
- J. Aguirre - Puente, President
- J. Malaurie, Vice - President
- J. P. Lautridou, Treasurer
- A. M. Cames - Pintaux, Secretary
The Second International Conference on Geornorphology took place at the University of Frankfurt between September 3 and 9, 1989. More than 650 abstracts of lectures and posters were accepted for presentation at this conference and are published. Permafrost related topics were mainly treated in section 5 (climate geomorphology), with a special subsection
devoted to periglacial geomorphology. During several one-day field trips, relict permafrost and periglacial features were demonstrated.
A special symposium was devoted to "Polar Geomorphology" and took place before the main conference in Bremen (August 30 to September 3). It was organized by the Institute for Physical and Polar Geography of the University of Bremen (Professor G. Stablin). 28 papers were presented to 35 participants from 15 different countries. Most of the papers presented in Frankfurt and in Bremen will be published in scientific journals, mainly in the Zeitschrift fur Geornorphologie or in Permafrost and Periglacial Processes.
Dr. Fujino and his members conducted a field survey near Tuktoyaktuk from late February through mid-March, 1989. A ground radar system was employed to check the distributions of massive ice bodies.
Dr. Oho, of the Environmental Science Department of Hokkaido University, and his group conducted a field survey in Svalbard from mid- June through mid-August this summer. Main objectives were the measurement of the growth of a Pingo in Advendalen, hydrological study of ground water from glaciers, and recent developments of ice-wedge relation to the
cracking process. During the previous year they installed ground temperature recorders and other necessary equipment at the site. Precise ground levelings were made to detect the recent upheaval of ground associated with pingo growth. A chemical analysis of the ground water was also performed on site.
Dr. Fukuda and his group conducted a field survey at Mt. Daisetu in central Hokkaido where they had previously reported the presence of alpine permafrost. Geophysical surveys were made by means of electrical resistivity and seismic profiling. According to a preliminary report, the permafrost table of alpine perrnafrost was estimated as 15 m thick. This reading matched a previous figure determined through annual ground temperature fluctuations.
Dr. Fukuda and his group will also conduct a field survey on permafrost occurrence in the Antarctic Peninsula area. They will cooperate with Prof. E. Retarnal from the University of Chile and Dr. J. Strelin of the lnstituto Antarctica Argentina. They will visit King George Island, Seymour (Marimbio) Island, and James Ross Island. The expedition will start in mid-November and will end in late January, 1990.
