The continents that we live and work on are dynamic things, being both added to and destroyed through time by plate tectonics. But is this a continuous process? Or does the planet work in stalls and spurts? A new study out today in Scientific Reports led by researcher Mathew Domeier provides some fascinating clues!
Hawaii sits at the end of a chain of volcanoes running across the Pacific Ocean floor, but in the middle of this chain lies a bend of 60 degrees. For many decades geoscientists have struggled to explain exactly how and why this feature occurred around 50 Million years ago. A new study in Science Advances led by postdoctoral researcher Mathew Domeier along with colleagues from the Centre for Earth Evolution and Dynamics (CEED), University of Oslo, sheds light on this long-standing geological controversy – A massive collision at the edge of the Pacific Ocean was the culprit.
This month members and international guests assembled in Tenerife for the conference "Conceiving Earth Evolution and Dynamics"
Deep beneath our feet lies a vast domain that is a record of hundreds of millions of years worth of geological history. A curious image of ancient rock graveyards plunging downwards and hot rising material pushing upwards is not far from the truth. A new study by Shephard et al. published today in Scientific Reports reveals an innovative technique of creating maps that image the interior of the Earth – a ‘colour-by-numbers’ guidebook to ancient oceans that once existed at the surface, if you will.
A new study of ash layers on Svalbard which provides valuable data about the formation of the North Atlantic Ocean has been recently published in the Nature Journal: Scientific Reports. Behind the new research are scientists from CEED in collaboration with colleagues from Massachusetts Institute of Technology/MIT and Store Norske AS.

Every year scientists from all over the world gather in Vienna to meet at the European Geosciences Union's (EGU) General Assembly. In 2017 this conference will be held from 23-28th April, and several CEED members are involved in convening various exciting sessions throughout the week, listed below.

Many solar system researchers met at the IAU Commission F1 Meteoroids 2016 at ESA/ESTEC, Noordwijk, Netherlands and Cometary Science After Rosetta Meeting 2016 at the Royal Society, London, England, both held in Jun 2016. CEED postdoc Aswin Sekhar was one of the participants for both conferences and presented the latest results representing the CEED Earth & Beyond Team. The primary aims of both these meetings were to enhance the studies of solar system small bodies and bring together researchers from different fields of astrophysics and geophysics communities to extend further collaborations.
Geoscientists with a wide range of expertise, and from across Europe recently met in Heraklion, Crete (2 - 4 Mar. 2016). CEED research associate Dr Adriano Mazzini was among them. The scientists discussed future collaborations to understand how fluids circulating in large fractures within the Earth's crust controls how faults move - through slow creeping processes or by sudden rupturing and earthquakes. The meeting was organized in the framework of 'FLOWS', a European research network funded through the Cooperation of Science and Technology (COST) program.
In August 2015, a group of researchers from the CEED Earth Crisis group went to Kamchatka to collect samples from the recent eruption of the volcano Tolbachik. An interesting finding was the presence of salt deposits, which can provide key information on the composition and chemistry of salts and metals in the volatile phase.
