Recently, members of the VUB AMGC research group (PhD-student Matthias Sinnesael (FWO) and former PhD-student dr. David De Vleeschouwer (MARUM, Bremen)) visited prof. Miroslav Zivanovic from the department of Electrical and Electronic Engineering in UPNA, Pamplona. This visit is a part of an international collaboration between geologists and engineers who have joined their forces in the study of cyclic (paleo-) climate research. The geologists are experienced and interested in cyclostratigraphy while the engineers – also in collaboration with VUB professor Johan Schoukens from the ELEC research group - have an extensive knowhow in the field of signal processing.

Major events punctuated the Paleozoic: ecological crises and diversifications, shifts in ocean chemistry, climatic changes, etc. One of the key-obstacles in understanding these events lays in the difficulty of providing precise estimates of the duration represented by a sequence of Paleozoic sedimentary rocks. This lack of temporal precision severely hampers the evaluation of forcing mechanisms and rates of climatic, ecological or biogeochemical changes in the Paleozoic. It is therefore essential to first improve the Paleozoic timescale to then unravel the history of the Paleozoic Earth system.
Laurine Burdorf (PhD student of Filip Meysman) recently won the ‘VLIZ Brilliant Marine Research Idea’ award. This award (up to 5000 euro) allows Laurine to execute a brilliant idea during her PhD within the frame of her research on cable bacteria. Laurine will use this to find out, on the level of genetics, ‘who’ exactly those interesting bacteria are …
We are looking forward to the results and congratulate Laurine with her brilliant idea!
The AMGC group at the Vrije Universiteit Brussel recruits PhD students to work on the IODP-ICDP core in the KT boundary Chicxulub crater.
In April 2016, IODP-ICDP drilled a core down to 1335 m in the 200 km in size Chicxulub crater, offshore Yucatan (see http://www.eso.ecord.org/expeditions/364/364.php). In the Fall
2016, the recovered material was described and sampled at the IODP Bremen core repository. Samples from the KT boundary interval, impactites, and uplifted granitic basement are available at the VUB. Building on more than 25 years at the forefront of KT research, the proposed doctoral theses are ﬁnanced by different projects focusing on the study of the material recovered by the IODP-ICDP drilling. The goals are to document the cratering process, peak-ring formation and melt production, understand ejecta production and deposition,
- constrain the products injected into the atmosphere, and their effect on the mass extinction,
- test the proposed connection between Chixculub and Deccan trap volcanism (see Renne et al. 2015),
- learn from Chicxulub to understand the evolution of terrestrial planets…
All new ideas are welcome, so are interaction with other AMGC members working on similar topics.
The PhD funding is for a duration of max. 4 years. Starting dates are ﬂexible, preferentially Spring - Summer 2017. Applications will remain open until all positions are ﬁlled. Enthusiastic and motivated scientists are encouraged to apply. The PhD salary makes it possible to live comfortably in Brussels and includes beneﬁts (transport, medical etc.).
'Dag van de Wetenschap' is all about bringing science to the people and AMGC is very proud to have been part of this. We wanted to show that science is hiding everywhere, even in places people don't always suspect. So we teamed up with our colleagues from archaeology and engineering to talk about archaeological science and palaeontology. Behind the organization is the interdisciplinary group ArCPIG, supported by AMGC, SKAR and SURF.
The team’s new work has confirmed that the asteroid, which created the Chicxulub crater, hit the Earth’s surface with such a force that it pushed rocks, which at that time were ten kilometres beneath the surface, farther downwards and then outwards. These rocks then moved inwards again towards the impact zone and then up to the surface, before collapsing downwards and outwards again to form the peak ring. In total they moved an approximate total distance of 30 kilometres in a matter of a few minutes.
