UN Subcommittee on Geodesy established

 

August 4th the UN-GGIM seventh session in New York endorsed the terms of reference and formally established the first permanent UN-GGIM Subcommittee on Geodesy.

Last August the United Nations Committee of Experts on Global Geospatial Information Management (UN-GGIM) decided to elevate the Global Geodetic Reference Frame (GGRF) Working Group to a permanent Subcommittee on Geodesy.

Following this decision the GGRF Working Group drafted the Terms of Reference (TOR) for the subcommittee and developed a transition plan from Working Group to Subcommittee on Geodesy. This August, during the UN-GGIM seventh session, the Terms of Reference and transition plan were endorsed by the UN-GGIM Committee of Experts. The transition phase will end at the inaugural meeting of the subcommittee where co-chairs will be elected in line with the TOR’s . Until then the subcommittee will continue to be co-chaired by Australia (represented by Geoscience Australia) and Norway (represented by the Norwegian Mapping Authority).

Long term priority

"The creation of this subcommittee in the United Nations System, the first for UN-GGIM, sends a very clear message to Member States, and other global geodetic entities, that enhancement of geodetic reference frames should be a long term strategic priority for governments,” says Gary Johnston, co-chair of the UN-GGIM Subcommittee on Geodesy.

IAG supports UN

The IAG has been a member of the GGRF Working Group from the start and will be an associate member of the new Subcommittee on Geodesy.

“The International Association of Geodesy supports the transition to the new Subcommittee on Geodesy. We also applaud the continued progress in developing an implementation plan for the GGRF road map. The International Association of Geodesy, through its geodetic services as well as the Global Geodetic Observing System, will continue its long-standing support of developing a global geodetic reference frame for the benefit of science and society,” says Dr. Michael Pearlman, who represented the IAG in New York.

Alligned with NASA goals

"The activities of the UN-GGIM, specifically its Subcommittee on Geodesy and the implementation of the recommendations described in the road map on the Global Geodetic Reference Frame, are well aligned with NASA geodesy goals," says Dr. Benjamin Phillips, program scientist for NASA's Space Geodesy Program in Washington and also present at the UN-GGIM seventh session in New York.

"The Subcommittee on Geodesy will help to facilitate the international collaboration that is critical to realizing the objectives of the global geodesy community, and further the associated scientific and societal benefits," says Phillips.

Inaugural meeting in November

The inaugural meeting of the subcommittee is planned in the margins of the 2017 UN-GGIM High Level Forum in Mexico City in November.

Along with the planning of the inaugural meeting the subcommittee is working on the development of the implementation plan for the GGRF roadmap.

"The work is progressing and the intention is to present the plan to the UN-GGIM Committee of Experts at its eight session in August next year”, says Laila Løvhøiden, co-chair of the UN-GGIM Subcommittee on Geodesy.

“The ambition is that the implementation plan will be the first step on the road towards an accurate, accessible and sustainable Global Geodetic Reference Frame to support science and society, which also is the vision of the implementation plan," says Løvhøiden.

Appropriate governance arrangements

The framework for an appropriate governance mechanism is beginning to take shape. The focus group assigned to develop the position paper agrees that in order to effectively implement the road map for the global geodetic reference frame, some kind of intergovernmental arrangement must be established. “Recognizing the critical importance of such a governance structure, it´s imperative that we engage in broad consultations before we conclude,” says Laila Løvhøiden, team lead of the UN-GGIM GGRF governance focus group.

IAG-IASPEI Joint Scientific Assembly

Kobe, Japan, July 30 – August 4, 2017

 

The International Association of Geodesy (IAG) and the International Association of Seismology and Physics of the Earth’s Interior (IASPEI) held for the first time a joint Scientific Assembly from July 30 to August 4, 2017 in Kobe, Japan. Overall 43 symposia were organized, 7 IAG, 27 IASPEI and 9 Joint Symposia. By the deadline, authors from 74 countries had submitted 1270 abstracts, 290 for IAG, 650 for IASPEI and 330 for the Joint Symposia. Altogether 1107 attendees from 65 countries registered, 361 of those with preference for IAG.

In total, 15 IAG travel awards were granted to young scientists for participation and presentation in the assembly. During the IAG Opening Session, IAG young author awards were presented to Xingxing Li, GFZ Potsdam, Germany, and Olga Didova, DUT, The Netherlands, for best publications in the Journal of Geodesy in the years 2015 and 2016, respectively (see IAG Newsletter July 2017).

The IAG Symposia were divided according to the IAG structure of Commissions, Services and the Global Geodetic Observing System (GGOS); the Inter-Commission Committee on Theory being involved in all symposia:

G01 Reference frames (50 presentations);

G02 Static gravity field (63 presentations);

G03 Time variable gravity field (38 presentations);

G04 Earth rotation and geodynamics (31 presentations);

G05 Multi-signal positioning: Theory and applications (26 presentations);

G06 Geodetic remote sensing (39 presentations);

G07 GGOS and Earth monitoring services (43 presentations).

 

Main topics of the G01 symposium were the International Terrestrial Reference Frame (ITRF), the Celestial Reference Frame and VLBI, regional reference frames and networks, the methodology and implementation of reference frames, and the combination and co-location of space geodetic techniques.

The G02 symposium dealt with the theory and methods of gravity field modelling, gravimetry, regional gravity and geoid determination, applications of the gravity field, satellite altimetry and the marine geoid, and height systems.

Presentations in G03 concentrated on time-varying gravity field estimation, methods and solutions. Current and future satellite gravity missions, mass transport and redistribution, and applications to Solid Earth, atmosphere, cryosphere, and hydrosphere studies were discussed.

The themes of G04 included specific topics of Earth rotation (nutation, EOP, polar motion, angular momentum, excitation functions, etc.) and geodynamics (horizontal and vertical crustal movement and deformation, tectonic elements, and strain measurements).

Principal topics of G05 were indoor and outdoor navigation, single and multi GNSS analyses, and positioning applications.

The G06 symposium addressed in particular the monitoring of the atmosphere (troposphere and ionosphere) and space weather. Methods concentrated mainly on GNSS sensing, VLBI, and GNSS reflectometry.

Themes of the symposium G07 were split into activities on reference frames and gravity, especially those of the GGOS Bureaus, the observation networks and co-locations, and the GGOS focus areas on height systems, geohazards, sea level, and space weather research.

 

Due to the seismic region of the venue, the joint symposia included particularly themes related to earthquakes and generated deformations:

J01 Monitoring of the cryosphere;

J02 Recent large and destructive earthquakes;

J03 Deformation of the lithosphere: Integrating geodesy and seismology through modelling;

J04 Geohazard early warning systems;

J05 Crustal dynamics: Multidisciplinary approach to seismogenesis;

J06 The spectrum of fault-zone deformation processes (from slow slip to earthquake);

J07 Tracking the sea floor in motion;

J08 Imaging and interpreting lithospheric structures using seismic and geodetic approaches;

J09 Geodesy and seismology general contributions.

 

In the following, we shall mention specific topics related to IAG activities.

The symposium J01 included contributions to the glacial isostatic adjustment in Antarctica, Scandinavia and North America, glacier velocities, and sea level rise due to melting, using data from absolute gravity measurements and dedicated satellite missions.

In symposium J02, there were studies of co-seismic crustal deformation caused by large earthquakes in different regions of the Earth,

while the symposium J03 dealt with results of post-seismic deformation using GNSS campaign or continuous observations. Time-series analyses and regional deformation patterns were presented using different approaches.

The geodetic contributions in J04 concentrated on real-time observations by GNSS precise point positioning and ionosphere disturbances as well as real-time sea level observations by satellite altimetry.

The symposium J05 included presentations of crustal deformations derived from GNSS and InSAR observations in various seismically active regions of the Earth.

In symposium J06, there were contributions on fault-zone deformations derived from gravity changes and strain-measurements.

Geodetic contributions in symposium J07 concentrated on detecting sea floor deformations by combining GNSS and acoustic observations. In addition, GRACE observations were used for modelling the ocean bottom pressure.

The symposium J08 included studies on the inversion of gravity anomalies and gravity field models for interpreting the lithosphere structure.

The symposium J09 was open to any topic not covered by the other joint symposia. Geodetic contributions dealt with InSAR observations for analysing earthquake types, tide gauge records for tsunami studies, and GNSS observations for specific crustal motions.

 

There were many innovative and trend-setting contributions in all the symposia. A very positive fact was that the session chairs observed strictly the time for presentations, so there was nearly always time for questions and discussion, and no truncation of talk time. Reviewed papers will be published in the IAG Symposia Series at Springer-Verlag. The deadline for submission is September 30, 2017.
