The lost Tethyan seaways: A deep-Earth and deep-time perspective on eastern Tethyan tectonics

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 GENESIS Hub, The University of Sydney. The southern and south ...[Read More]

Identification of past methane emission altering the foraminiferal tests by secondary overgrowth of calcium carbonate.

Identification of past methane emission altering the foraminiferal tests by secondary overgrowth of calcium carbonate.

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 done on foraminifera called Cassidulina neoteretis , which is a ty ...[Read More]

Image of the Week: Petermann Glacier

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 cliffs and plunging to more than 1100 m below sea level at its deepest point. In 2 ...[Read More]

Unseen but not unfelt: resilience to persistent volcanic emissions

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 been left in the shadow of the public attenti ...[Read More]

Everything is connected

Post by Anne Van Loon, Lecturer in Physical Geography (Water sciences) at the University of Birmingham, in the United Kingdom. __________________________________________________ In recent years the human dimension of hydrology has become increasingly important. Major flood and drought events have shown how strongly water and society are intertwined (see here and here). The hydro(geo)logical resear ...[Read More]

GeoTalk: The anomaly in the Earth’s magnetic field which has geophysicists abuzz

Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak to Jay Shah, a PhD student at Imperial College London, who is investigating the South Atlantic Anomaly, a patch over the South Atlantic where the Earth’s magnetic field is weaker than elsewhere on the globe. He presented some of his recent findings at the 2017 General Assembly. First, coul ...[Read More]

Mexico earthquakes: What we know so far

On Friday 8 September 2017 at 04:49 am UTC, a magnitude 8.1 earthquake hit off the coast of Mexico, 87 km SW of Pijijiapan. According to the U.S. Geological Survey, the epicentre was at 15.07 N, 93.72 W at a depth of about 69.7 km. Yesterday, another strong (magnitude 7.1) earthquake hit central Mexico, 55 km SSW of the city of Puebla and 120 km south of Mexico City. Despite the lower magnitude, y ...[Read More]

Investigation of methane emissions in marine systems

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 how the fluid flow systems work. With our research, we can contribut ...[Read More]

Miho Janvier – The Quest for Solar Storms

In this month’s (first ever for our blog) Life of a Scientist interview, we are very happy to talk to Dr Miho Janvier, a Researcher at the Institut d’Astrophysique Spatiale in Orsay (France), whose work has shed some light on the understanding of solar eruptions and coronal mass ejections  (or solar storms) from their birth in the Sun’s corona to their evolution in interplanetary space ...[Read More]

Image of the Week – ROVing in the deep…

Robotics has revolutionised ocean observation, allowing for regular high resolution measurements even in remote locations or harsh conditions. But the ice-covered regions remain undersampled, especially the ice-ocean interface, as it is still too risky and complex to pilot instruments in this area. This is why it is exactly the area of interest of the paper from which our Image of the week is take ...[Read More]
