On behalf of the IUGG2019 Local Organising Committee, I welcome you to the 27th General Assembly of the International Union of Geodesy and Geophysics, held in Montréal, Canada in July 2019.


The International Union of Geodesy and Geophysics (IUGG) is a non-governmental scientific organisation, one of 40 that make up the International Science Council (ISC). Its mandate covers a diverse range of scientific studies of the Earth, including solid-Earth dynamics, earthquakes and volcanoes, the hydrological cycle including snow, ice and glaciation, atmospheric and ocean sciences, and the Earth’s magnetic and gravitational fields.


Every four years, the IUGG holds a General Assembly, where scientists from these different disciplines meet to present and discuss the most important issues that are covered in their research, and the value of this research to society. Topics are wide-ranging and the research cutting-edge, including: climate change and its impacts on water availability, plastic waste and ocean life, the causes and impacts of tsunamis, ice-sheet melt and sea-level rise, damaging earthquakes, impacts of pollution on ecosystems, and many others.


Montréal was chosen as the venue for the 27th General Assembly, which also marks a special anniversary – the centennial celebration – for the IUGG. This year, the Assembly will be hosted by two Canadian scientific societies, the Canadian Geophysical Union (CGU) and Canadian Meteorological and Oceanographic Society (CMOS).


Join us at the Palais des Congrès, Montréal, for 9 days of scientific symposia, keynote presentations, awards, special lectures, a public documentary screening and panel discussion, and a wide range of scientific workshops.

The Press Room will be located in room 515B of the Palais des Congrès.

Summary of Media and Communications Highlights


The International Association of Geodesy and Geophysics (IUGG) is the main organization that brings together scientists from 8 associations focused on specific fields of research, from around the world for a General Assembly every four years. The 8 associations are:


  • International Association of Cryospheric Sciences (IACS)
  • International Association of Geodesy (IAG)
  • International Association of Geomagnetism and Aeronomy (IAGA)
  • International Association of Hydrological Sciences (IAHS)
  • International Association of Meteorology and Atmospheric Sciences (IAMAS)
  • International Association for the Physical Sciences of the Oceans (IAPSO)
  • International Association of Seismology and Physics of the Earth's Interior (IASPEI)
  • International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI)


The IUGG 2019 General Assembly is the 27th, and 2019 marks the 100th anniversary of IUGG, with the theme “Beyond 100: The next century in Earth and Space Science”. As part of IUGG 2019, there will be 9 days of scientific sessions and workshops split up into more than 200 thematic symposia (9th-17th July), with almost 4000 scientists from 90 countries discussing cutting edge Earth and Space Science research. Topics covered will be wide-ranging, including:


  • climate change impacts on water availability
  • plastic waste and ocean life
  • causes, likelihoods and impacts of tsunamis
  • ice sheet melt and sea level rise
  • climate change and maritime and weather risks
  • damaging earthquakes
  • impacts of pollution on ecosystems


Specific highlights of interest to the media and public will be published shortly, and the full searchable scientific program can be found here:!sessionschedule


In addition to the scientific sessions and workshops, there will be several notable events during IUGG 2019, including:

  • The Union Lectures
    Leading experts representing the IUGG and each of the 8 associations will be providing insights and societal challenges specific to their fields, in 30-minute presentations taking place from 10:30am-12:00pm on July 11th, 13th, and 15th.

  • Public Lecture: the Canada C3 – Coast to Coast to Coast Documentary 
    A film about the Canada C3 project, highlighted by a 150-day ship-based expedition around Canada’s coast, will be shown in English and French, followed by a bilingual roundtable on July 9th from 7:00-8:30pm.

    • IUGG Gold Medal Recipient Lecture
    W. Richard Peltier, from the Department of Physics, University of Toronto, will be awarded the IUGG Gold Medal, for “his scientific contributions that have been pioneering and profound in deep earth physics and climate system processes, and for his unselfish contributions to international scientific collaboration”. He will be giving a special Gold Medal Lecture on glaciers and climate on July 17th from 2:00-3:00pm.

    • The Prince Albert I Medal recipient for 2019 and Albert I Memorial Lecture
    Corinne Le Quéré, Professor of Climate Change Science, University of East Anglia, will be awarded The Prince Albert I Medal by the International Association for the Physical Sciences of the Oceans (IAPSO) for “for her fundamental contributions to our understanding of ocean biogeochemistry and global carbon cycling, and her work to quantify the ocean's role in the uptake of global carbon emissions”. She will be giving a special Albert I Memorial Lecture at the IAPSO award ceremony on 12th of July, from 5:00-6:00pm.
    Also see the IAPSO website:

  • Celebrating 100 Years of Volcanic Activity: 1919-2019
    The International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) will celebrate their centennial with a dedicated entire day of invited talks aimed at highlighting the progresses of volcanology over the last 100 years. Invited talks will cover advances in our understanding of how volcanoes work, crisis management, and the impacts of eruptions on weather and climate. Talks will take place on 12th of July from 8:30am-6:00pm.
