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),
  
• U3 - Mathematics of Planet Earth: The Science of Data (IASPEI, CMG),
  
• 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;
  
• Lisa Tauxe (IAGA): Hunting the magnetic field;
  
• Veena Srinivasan (IAHS): Understanding and transforming water conflicts in the Anthropocene;
  
• Ed Hawkins (IAMAS): The value of rescuing millions of lost historical weather observations using volunteer citizen scientists;
  
• Karen Kohfeld (IAPSO): The Ocean’s Role in Atmospheric Carbon Dioxide Changes During Ice Age Cycles;
  
• Vera Schlindwein (IASPEI): Singing seismograms – harmonic tremor signals in seismological records;
  
• Paolo Papele (IAVCEI): Volcanic giants - what we know, what we think we know, what we can’t know about cataclysmic super-eruptions.

The joint symposia are always led by an association with co-conveners from other associations. IAG has the lead of the following Inter-Association Symposia:

• JG01 - Interactions of Solid Earth, Ice Sheets and Oceans;
  
• JG02 - Theory and Methods of Potential Fields;
  
• JG03 - Near-Real Time Monitoring of Regional to Global Scale Water Mass Changes;
  
• JG04 - Geodesy for Atmospheric and Hydrospheric Climate Research;
  
• JG05 - Remote Sensing and Modelling of the Atmosphere;
  
• JG06 - Monitoring Sea Level Changes by Satellite and In-Situ Measurements;
  
• JG07 - Monitoring, Imaging and Mapping of Volcanic Belts;
  
• JG08 - Earth Systems Literacy:  Geophysics in K-16 Class Rooms, Outreach Projects, and Citizen Science Research Projects;

and IAG is sponsoring (with IAG co-conveners) the following Inter-Association Symposia led by other associations:

• JA01 - Geophysical Constraints on the Earth's Core and Its Relation to the Mantle;
  
• JA02 - Geophysical Data Assimilation;
  
• JA03 - Geophysical Records of Tectonic and Geodynamic Processes;
  
• JA06 - Space Weather Throughout the Solar System: Bringing Data and Models Together;
  
• JA07 - Geoscience Data Licensing, Production, Publication, and Citation (IAGA);
  
• JA08 - Probing the Earth’s Lithosphere and Its Dynamics Using Geophysical Modeling;

International Scientific Societies meet in Hannover for the Day of Geodesy

During the Day of the Geodesy on May 24, 2019, the leaders of four international scientific societies in the field of geodesy and geoinformatics met in Hannover for talks on possible collaboration. Prof. Monika Sester (Leibniz University Hannover) represented the International Cartographic Association (ICA) as its Vice President; the other three societies were represented by their presidents: Prof. Harald Schuh (German Research Centre for Geosciences GFZ in Potsdam) participated in the meeting for the International Association of Geodesy (IAG), Prof. Rudolf Staiger (University of Bochum) for the International Federation of Surveyors (FIG) and Prof. Christian Heipke (Leibniz University Hannover) for the International Society for Photogrammetry and Remote Sensing (ISPRS). What is remarkable about this meeting is that all four representatives come from Germany; an unprecedented constellation in the, for some of the societies, more than 100-year history.

The morning began at the Leibniz University with presentations from each international organization to an interested professional audience. The four representatives then met for a 45-minute public panel discussion in the city centre, in which they highlighted the role of geodesy and geoinformatics for society at large. In addition to the classical task of surveying and mapping of the earth's surface and documenting the legal boundaries, the main topic was the role of geodesy in the age of digitization and climate change, e.g. for mobility and autonomous driving, for sustainable urban and rural development, for earth observation and natural hazards, and also in robotics and navigation. Without the often less visible geodetic contributions, reliable data would not be available in the required quality, neither for sea level rise nor for high-precision positioning in real-time or in disaster management.

With the use of the full range of their research, the geodesists also expect to make significant contributions to achieving the United Nations' Sustainable Development Goals (SDGs). According to estimates by the World Bank, approximately just 30% of land is registered worldwide, which is why experts in cadastre and land management are in great demand.

In addition to this, all speakers emphasized the broad field of activity and the fascination of geodesy - a field in which full employment is virtually guaranteed in most countries today. With this background, the subject of geodesy and geoinformatics is highly recommended to prospective students.

The representatives of the scientific societies later met for an internal exchange of ideas, in which possibilities for closer cooperation were discussed. An improved exchange of information between the societies, and a common representation at, and organisation of, scientific and professional meetings and events for outreach and further education were agreed upon, especially in areas where overlapping interests exist. Cooperation is also to be intensified in areas relating to geodesy and geoinformatics in general, such as education and recruitment, scientific publications, and the visibility of the subject in politics, administration and the society at large, on a national and international level.
