The IAG Newsletter is under the editorial responsibility of the Communication and Outreach Branch (COB) of the IAG.

It is an open forum and contributors are welcome to send material (preferably in electronic form) to the IAG COB (newsletter@iag-aig.org). These contributions should complement information sent by IAG officials or by IAG symposia organizers (reports and announcements). The IAG Newsletter is published monthly. It is available in different formats from the IAG new internet site: http://www.iag-aig.org

Each IAG Newsletter includes several of the following topics:

1. news from the Bureau Members
2. general information
3. reports of IAG symposia
4. reports by commissions, special commissions or study groups
5. symposia announcements
6. book reviews
7. fast bibliography

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;
• JH02 - Climate and Hydrological Services: Bridging from Science to Practice and Adaptation;
• JP01 - Tides of the Oceans, Atmosphere, Solid Earth, Lakes and Planets;
• JS01 – Cryoseismology;
• JS02 - Early Warning Systems for Geohazards;
• JS03 - Subduction Zone Deformation and Structure: Tracking the Sea Floor in Motion;
• JS04 - Seismo – Geodesy;
• JS05 - Probabilistic & Statistical Approaches in Geosciences;
• JS06 - Old Data for New Knowledge: Preservation and Utilization of Historical Data in the Geosciences;
• JS07 - Integrated Geophysical Programs for Earth Systems Monitoring;
• JV03 - Strain Localisation and Seismic Hazards.

The IAG specific symposia are the main issue of the IAG General Assembly:

• G01 - Reference Systems and Frames;
• G02 - Static Gravity Field and Height Systems;
• G03 - Time-variable Gravity Field;
• G04 - Earth Rotation and Geodynamics;
• G05 - Multi-signal Positioning, Remote Sensing and Applications;
• G06 - Monitoring and Understanding the Dynamic Earth with Geodetic Observations.

For all details of the symposia descriptions and the program, please visit the IUGG2019 Homepage (http://iugg2019montreal.com/). The most important deadlines are:

• May 15, 2019: Presenting Authors Registration deadline to the website;
• May 31, 2019: Complete scientific program details published.

IAG invites all geodesists to participate in the General Assembly 2019 and to present their work in one of the symposia. We look forward to seeing you in Montreal!
