Every 8 weeks we turn our attention to a Remarkable Region that deserves a spot in the scientific limelight. Following from the first entry which showcased the Eastern Mediterranean, we move further east, and back in time, to the realm of the Tethys. The post is by postdoctoral researcher Sabin Zahirovic of the EarthByte Group and Basin …[Read More]
Agung volcano, a 3.1 km high cone located in the east of Bali, Indonesia, which last erupted in 1963 killing ~1500 people (Self and Rampino, 2012), is currently undergoing seismic unrest, and steam/gas emissions have been observed at the surface. This has led the Indonesian authorities to evacuate areas around Agung which could be affected …[Read More]
Ever heard about foraminifera? These tiny benthic (living at the seafloor) marine organisms are common in oceans across the globe and can be used to accurately give relative dates to sedimentary rocks. But we can also use them to identify past methane emissions from the seabed by studing their test or shell! The measurements were …[Read More]
Our image of the week shows the area around the calving front of Petermann Glacier through the spring, summer, and autumn of 2016. Petermann Glacier, in northern Greenland, is one of the largest glaciers of the Greenland Ice Sheet. It terminates in the huge Petermann Fjord, more than 10 km wide, surrounded by 1000 m …[Read More]
The last decade has been inundated with reports of environmental disasters impacting the lives of billions of people around the world. While news coverage of floods, hurricanes, earthquakes or wild fires are always accompanied with spectacular images of destruction that emphasise the speed at which they strike, a myriad of slow and latent hazards have …[Read More]
Extracurricular activities for current and former geosciences students provide great value to early career scientists in terms of networking and broadening their scientific horizon. PhD student Maximilian Döhmann, who studies rock deformation with numerical models based on high temperature and pressure torsion experiments in the Geodynamic Modelling group of GFZ Potsdam, shares his experiences with …[Read More]
Volcanic Ash as an Active Agent in the Earth System (VA3): Combining Models and Experiments; Hamburg, Germany, 12–13 September 2016 Volcanic ash is a spectacular companion of volcanic activity that carries valuable information about the subsurface processes. It also poses a range of severe hazards to public health, infrastructure, aviation, and agriculture, and it plays …[Read More]
In an earlier post, we talked briefly about below-ground ice and the consequences of its disappearing. However, to estimate the consequences of disappearing ground ice, one has to know that there actually is ice in the area of study. How much ice is there – and where is it? As the name suggests, below-ground …[Read More]
Nowadays, equality is cool. Everyone is always going on about how women and men should get the same opportunities. In science, and hence, geodynamics, women are still a bit behind men for both historical (women only recently started graduating more in exact sciences) and unconscious-bias reasons. Therefore, there are lots of programs in order to …[Read More]
Ever wondered how we can measure methane emssions from the seafloor ? And ever wanted to steer a mini submarine remotely operating vehicle (ROV)? Well here´s your chance! Have look at this blog post on analyzing methane emissions using ROVs and you´re ready to embark! The goal is to determine when the gas leak started and …[Read More]
