Traditionally geodesy is the science of the measurement and the mapping of the Earth’s surface. Since the surface is mainly shaped by the Earth’s gravity field the classical definition includes the Earth’s gravitational potential. Observing the Earth figure, the orientation and rotation as well as the gravity field, geodesy today provides spatial and temporal patterns of geophysical processes within the Earth system such as sea level rise, tides, melting of continental ice masses, changes in global water circulation and in the atmosphere or deformations of the solid Earth. Consequently, the geodesy division covers activities on the whole spectrum of modern geodetic Earth system modeling from the measurement systems to the investigation of geophysical processes.
The 2018 Vening Meinesz Medal is awarded to Markus Rothacher for his pioneering work in linking geometry, rotation and gravity to space geodetic observations and subsequently enhancing the understanding of the Earth system.
The 2018 Division Outstanding Early Career Scientists Award is awarded to Sara Bruni for her innovative contributions to global and regional reference-frame studies bridging the gap to other fields of geosciences, such as geodynamics.
The 2017 Vening Meinesz Medal is awarded to Isabella Velicogna in recognition of her pioneering and groundbreaking work on the application of time-variable gravity for ice-sheet mass balance and land-water hydrology studies.
The 2017 Division Outstanding Early Career Scientists Award is awarded to Xingxing Li for his innovative contributions in improving the performance of precise point positioning, significantly extending the high-rate GNSS applications in geosciences.
The 2017 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Florian Andritsch Comparing tracking scenarios to LAGEOS and Etalon by simulating realistic SLR observations
Congratulations again to Sara Bruni for receiving the Geodesy Division Outstanding Early Career Scientist Award 2018! A summary of her research on new findings in the gravity field time series from Medicina is posted below. Maybe you know an Early Career Scientist who does as outstanding work as Sara Bruni does? Nomination is the first crucial step in order to receive an award, don’t let this opportunity pass and nominate an outstanding colleague for an EGU Award or Medal in …
View of the Medicina observatory. The site hosts a superconducting gravimeter (SG) installed in a dedicated building next to a piezometer. Local height variations are monitored by means of two GPS stations, located at the end of the N-S segment of the “North Cross” radio telescope. The two GPS stations are about 30 m apart and are close to a VLBI antenna. Geodetic observations have proven to provide a fundamental base for advances in Earth-system sciences, while simultaneously supporting critical …
One day in January, we heard it through the grapevine that we were supposed to submit abstracts to an event called EGU. So we asked ourselves: What exactly is EGU? Our colleagues told us: ‘EGU is a huge, international conference worth going. And you will have a lot of fun.’ So we submitted our abstracts and hoped for the best. Three months later, we entered the airport with a poster box and some of our colleagues. Immediately, the excitement started …
More than 15.000 participants with great presentations in 666 sessions (posters, PICOs, and orals) made the EGU General Assembly 2018 at the Austrian Convention Centre in Vienna a great success. In the geodesy-led programme, we had 428 submissions, which were distributed to 19 oral blocks, 3 PICO sessions, and a series of poster sessions. We listened to exciting talks, starting with geodetic theory on Monday morning and ending with presentations on VLBI and SLR observations to artificial objects in space …
This month we are highlighting two new studies published in EGU journals. One, published in The Cryosphere, shows how much sea level would rise following the collapse of two Antarctic ice shelves. The other, featured in Biogeosciences, shows that oxygen loss in the coastal Baltic Sea over the past century is unprecedented in the last 1500 years. You can read the press releases for both studies on the EGU website.
Also this month, we have opened the call for candidates for EGU Treasurer: if you'd like to nominate yourself or propose a candidate, you can do so by 15 September.
Finally, if you'd like to apply for financial support from the EGU to organise a meeting, make sure to submit an application by 15 August. This is also the deadline to submit proposals for Union Symposia and Great Debates at the EGU 2019 General Assembly. The deadline for scientific sessions is 6 September.
