The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) is a collaborative contribution of the global geodesy community to the observation and monitoring of the Earth System. Geodesy is the science of determining the shape of the Earth, its gravity field, and its rotation as functions of time. Essential to reaching …[Read More]
Africa hosts the world’s most extensive subaerial rift system on Earth known as the East African Rift System (EARS). It stretches over 5000 km from the Red Sea and Gulf of Aden intersection in the north to the Southwest Indian Spreading Ridge south of South Africa. East-West, the EARS spans the eastern border of …[Read More]
Getting the small g (the absolute gravity value) outdoors has always been some sort of a challenge. But, in the early 2000s the possibility to measure gravity has changed by the arrival of the first A10 absolute gravimeters. They to a large extent revolutionized the approach of performing gravity measurements in the open field and …[Read More]
On 14th of November 1934, the Dutch travelled to the harbor of Den Helder situated in the north of the Netherlands to catch a glimpse of the departure of Hr. Ms. K-XVII: A submarine of the Royal Dutch Navy setting sail on a trip around the world. Onboard was a unique traveler and with …[Read More]
Stories from the field – how exactly are those GPS data collected? The geodesy community at large benefits from the many science projects with open data policies. A user simply has to navigate to a data portal, download the data, and within a matter of moments a world of possibilities opens up for potential …[Read More]
Antarctica is well known for its large ice sheet, covering 98% of the continent. A large part of the ice sheet is losing mass leading to vertical and horizontal movements of the crust as well as changes of the gravitational attraction. To observe these changes in gravity with the highest accuracy, it is necessary …[Read More]
Have you ever wondered what it means to start a PhD during the pandemic? Below you can get more insights. Hi! I’m Öykü, a PhD student at Politecnico di Milano in Italy. I’m originally from Turkey and did my MSc at Istanbul Technical University. My research focus is static and time-variable gravity field …[Read More]
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 …[Read More]
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 …[Read More]
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 …[Read More]
