General Announcements

27th IUGG General Assembly, Montreal, Canada, July 8 – 18, 2019

The International Union of Geodesy and Geophysics (IUGG) holds its 27th General Assembly from July 8 to 18, 2019 in Montreal, Canada. The general assembly theme is the celebration of the centennial of the IUGG establishment in Brussels, Belgium, in 1919.

IUGG holds its General Assemblies every four years. Traditionally, the eight constituent associations of IUGG (Cryospheric Sciences, IACS; Geodesy, IAG; Geomagnetism and Aeronomy, IAGA;

Hydrological Sciences, IAHS; Meteorology and Atmospheric Sciences, IAMAS; Physical Sciences of the Ocean, IAPSO; Seismology and Physics of the Earth's Interior, IASPEI; and Volcanology and Chemistry of the Earth's Interior, IAVCEI) arrange their General Assemblies in parallel with the IUGG. This enables to hold joint inter-association symposia besides the specific association symposia and a greater involvement in the IUGG symposia.

There will be nine Union Symposia organized by IUGG and each of the associations in cooperation with the IUGG Commissions (Climatic and Environmental Changes, CCEC; Mathematical Geophysics, CMG; Geophysical Risk and Sustainability, GRC; Study of the Earth's Deep Interior, SEDI; Data and Information, UCDI; Planetary Sciences, UCPS), the IUGG Working Group on History (WGH), and the Global Geodetic Observing System (GGOS).

  • U1 - Achieving Sustainable Development: The Role for Earth Sciences (IACS, CCEC),
  • U2 - Georisk Reduction: Science, Resources, and Governmental Action (IAVCEI, GRC),

  • U4 - Data-driven Science for Earth and Space Exploration (IAPSO, UCDI),
  • U5 - New Discoveries in Earth Deep Interior (IAGA, SEDI),
  • U6 - Recent Advances and Discoveries in Planetary Science and Comparative Planetology (IAMAS, UCPS),
  • U7 - Centennial of the International Cooperation in Earth Sciences (IAHS, WGH),
  • U8 - Earth and Space Observations (IAG, GGOS),
  • U9 - Celebrating Early Career Scientists (IUGG).

In addition, there will be nine Union Lectures given in three special sessions by representatives of the IUGG and associations:

  • David Grimes (IUGG): Earth Sciences as the Underlying Pillars to Meet Societal Challenges in the next Century;
  • Waleed Abdalati (IACS): Exploring and Understanding Earth from Space: The Power of Perspective;
  • Kosuke Heki (IAG): No geodesy, no geophysics;

The  great  contribution  for  T. J. Kukkamäki  written  by  the  Geodesist  and  Astronomer Juhani Kakkuri contains 12 Chapters and an informative Appendix:

Family background
From graduate to a civil servant
Head of the Finnish Geodetic Institute

Triangulations with Kukkamäki
Precise leveling and stellar triangulations
Years in the United States
As a United Nation expert

In the chapter “Forward” the author reviews in short why T.J. Kukkamäki has been so important researcher for the research in Geodetic Science. He was a member of the Finnish Academy of Science and Letters and the Academy of Technical Sciences representing his life’s works for the Finnish Geodetic Institute. He started by the survey of leveling and lateral refraction studies as well as micro climate measurement conditions. He is famous for measurements of the solar eclipses, namely observing the complete solar eclipse of 1947, for measurement the distance of 5458.8 kilometers across the Atlantic from Eastern Coast of Brazil to the African Gold Coast, nearly two decades before the Satellite Era. He was fond of R.A. Hirvonen’s cooperation, another of great scientist of his time.

His scientific inventions and achievements were made together with his teacher Y. Väisälä. Me, the author, is very proud for receiving the Y. Väisälä Medal of the Finnish Academy of Science and Letters recently.

T.J. Kukkamäki was appointed Head of the Finnish Geodetic Institute in 1953, a position he held until his retirement in 1977. He started as a student at Turku Finnish University, his research culminated in his work in the United States in 1953 and 1954 by measuring by means of the Väisälä interference comparator in Finland and overseas, as well for his Leveling Work in Pechenga just before the outbreak of the Winter War. His triangulation measurements in the Northern Finland in the 1950 are legendary.

Internationally, T.J. Kukkamäki is well known for acting in the seventies as

President of the International Association of Geodesy

from 1975 to 1979. It was the time I met him first in Paris. He also acted as an UN Expert for the Technical Assistance in Burma being appointed by the UN General Secretary.

From the important chapter on Family and Background we mention his charming wife Anna-Liisa Kukkamäki, maiden name Järvinen. I met the two first when I had been at Uppsala University / Sweden / in 1975. I had been invited together with Professor Evangelos Livieratos – paid by the well-known Professor Erik Tengström / Uppsala – to see the most famous Finnish Geodetic Institute at that time located in Helsinki. At the harbor side we were welcomed by T.J. Kukkamäki and his deputy Juhani Kakkuri. We were invited to stay at home of Juhani and in the first evening I met Anna-Liisa and T.J.. At the welcome party in the home of Juhani I was invited to play piano: on top of my piano Anna-Liisa was singing famous songs we knew by heart. Anna-Liisa was outgoing, partially in contrast to T.J.. Indeed have a look at wedding picture showing Anna-Liisa Jänsinen and Tauno Kukkamäki in 1936 in page 19. See also the charming photo on page 20 at a conference in 1965. Her early death by an accident is very moving.

T.J. Kukkamäki completed his Master Thesis at the Finnish University Turku being presented in the chapter “From graduate to the civil servant”. He took lecture from Kalle and Yrjö Väisälä, both famous scientists internationally well known. T.J. chose Yrjö Väisälä as his supervisor: he completed his excellent Ph.D. Thesis in 1933: It was written in German!

“Untersuchungen über die meterendmasse aus geschmolzenem Quartz nach lichtinterferometrischen Methoden”

He was the youngest Doctor of Philosophy at the age of 23 years.

It is worth mentioning that a small planet has been called “Kukkamäki”, a minor planet number 2159 on the application of the Astronomer Liisi Oterma: 11 km diameter away from the Sun at a distance of 372 million km with orbital period around the Sun is 3.91 years. See the photo on page 35 of the influential Yrjö Väisälä, Professor of Physics and Astronomy of the Finnish University of Turku.

We did mention already the topics “Head of the Finnish Geodetic Institute” as well as “Measuring the base line”, the Nummela Length was presented on page 155 varying from 1947 to 1984 from 864.122.78 meters to 864.122.40 with standard estimated error up to ą0.09 millimeter. We also mentioned his work on “Solar Eclipses”, “Triangulation with Kukkamäki” started in the summer of 1952, “Precise leveling and stellar triangulation”, years in the United States from 1952 working for V.A. Heiskanen for “Geoid calculations”, “As a United States Expert” and “Finally Land Surveying and Geodesy”.

Consult the celebrated photos on page 111 in 1950 as well as 1971 with the celebrated Tarczy-Hornoch and T.J. in Sopron. For us the highlight is the final chapter in “International Cooperation”. The author of the book J. Kakkuri, the follower of T.J. as Director General of the Finnish Geodetic Institute, nowadays called Finnish Geospatial Research Institute, mentions first the accident of Anna-Liisa Kukkamäki in November 1977 who joint T.J. in most of the campaigns Nationally and Internationally. T.J. enjoyed very much his “Summer Villa” in Ikaalinen. I recall a short vacation time in Ikaalinen, an impressive Mäki: T.J. had invited me there serving an over-proved Whiski. In consequence I was sick for three days.

T.J. enjoyed his journey to the Pamir Mountains: in the autumn on 1977 he was invited by Professor Yuri Boulanger, Soviet Academy of Science, for a visit to the Geophysical Observatory in Gharm which was situated in a valley between the Alain and Pamir Mountains in Tajik: the ancient Silk Road to China. The valley was ideal for the measuring the movements of the Eurasian and Indian tectonic plates. Professor Boulanger thought mere breathing or wind could set the rocks in motion. T.J. was able to visit a research station located at the altitude of several thousand of meters on the slop of the mountains, Pik Lenina or Pik Kommunizma via helicopter. At this occasion he visited Samarkand a second time, another tectonically most interesting region.

“Kukkamäki in China”, “Journey around the World”, “The Lipizzaner horses” and “Last May Day” are the final sections. T.J. Kukkamäki died in the Laakso Hospital in Helsinki in the first day in 1998, exactly 69 years after the unforgettable evening when he celebrated May Day as a young graduate at the “Lily of Turku”. He is buried at the historical cemetery of the Heinola Perisa, close to the place where he was born.

After the successful book, V.A. Heiskanen Juhani Kakkuri wrote another master piece. All the time you feel his personal engagement with “T.J.”, his teacher. Being a member of the Finnish Academy of Science and Letters as well as initial member of the Writer’s Association he knows to write Literature. And the end of book, Juhani Kakkuri presents us with a detailed list of his sources as well as his 121 scientific papers: worth mentioning his last contribution about “Maupertuis et la Finlande” in 1986. We wish the book a wide audience: please, write to the National Land Survey of Finland, P.O.Box 84, 00521 Helsinki, Finland, for getting a copy,
