This is an aerial image taken from a balloon at around 150m height, at the eastern shoreline of the Dead Sea. Such “selfies” are scientifically valuable, providing important data that help researchers to analyze the morphology of the retreating lake and investigate associated hazards like sinkholes, subsidence and landslides. The older shorelines, visible as lines …[Read More]

GeoPolicy: How to use webinars to share your science with a wider audience!
Since the explosive spread of COVID19, the way most academics work has changed and it can sometimes feel like we’re all living on conference calls, Skype and online events. While this may not suit everyone’s preferred working style, it’s difficult to deny that people are now more willing to engage online and it’s worth thinking …[Read More]
Imaggeo On Monday: Patterns in the landform
The badlands at the Zabriskie Point (Death Valley, California, USA) rest upon a mudstone foundation. In the prehistoric lakes of Death Valley, fine grained sediments were deposited to form soft rocks. The clay minerals in the mudstone are shaped like tiny plates, which helps create the layers. The combination of the almost impermeable mudstone and …[Read More]
Geosciences Column: Thunderstorm asthma, the unexpected impact of lightning storms on pollen allergies.
In October 2015 a series of massive thunderstorms rolled across the Eastern Mediterranean. In the hours and days that followed many people living along the Israeli coast had to go to their nearest medical centre because they were experiencing respiratory problems, which appeared very similar to asthma. But what could have caused these breathing problems? …[Read More]
Imaggeo On Mondays: The valley along the fault
The Idrija fault is a an active fault crossing Slovenia for more than 100 km in a NW-SE direction and is responsible for several important geological features in the country. Among them, we can mention the former-active mercury mine of Idrija which has registered as a Unesco World Heritage site since 2012. Another example …[Read More]
LGBTQIA+ in the field
As a part of any field-based science work, whether it be as an individual scientist, research team or with students, we must first conduct a risk assessment. This often focuses on the physical dangers that you, your colleagues or students may encounter whilst working in stressful and sometimes unfamiliar environments. More recently, field-based risk assessments …[Read More]
Imaggeo On Mondays: Natural Arch
This natural arch named Pirulico’s tower is located in Mojácar, situated in the south east of the Province of Almería (Andalucia) in southern Spain. A natural arch, natural bridge or, less commonly, a rock arch is a natural rock formation where a rock arch forms, with an opening underneath. Most natural arches form as …[Read More]
Imaggeo On Mondays: “The most valuable thing we extract from the ocean is our existence” Dr Sylvia Earle
Marine plastic is just one of the many challenges facing the future of our oceans. For many years researchers have been attempting to understand this problem, but it can be surprising to learn how many things are still unknown, even in oceans we may think of as being familiar. The Mediterranean Sea is one such …[Read More]
Imaggeo on Mondays: The Grid – A serpentine pseudomorph after carbonate
The structures in this photo might look three-dimensional, but they are completely flat. It is a photo of a polished thinsection of a rock, taken through a petrographic microscope under cross-polarized light. The width of the image is just 2 mm. The brownish mineral around the edges is carbonate, the white to grey mineral in …[Read More]
