Palaeontology spans many disciplines, bringing together aspects of geochemistry, sedimentology, zoology and many more to piece together the puzzles of ecosystems past. From evolution to extinction, these fantastic films take you through the science that lets us put the puzzle together – enjoy! A Foram’s Tale One way reconstructing past climates is to culture living planktonic Foraminifera an ...[Read More]

Friday Photo (88): Volcanic Mud Pits
The Solfatara volcanic crater at Pozzuoli, part of the Campi Flegrei volcanic area, has many fumaroles and mud pools. The bubbling mud pits are created by rainwater and vapor condensation, which mix with the clay material present on the surface of the volcanic crater. The gas composition which spews out from the mud pit is varying (H2S, N2O, H2O, CH4, He, C); the liquid composition is as rich (Bor ...[Read More]

Guest Blog: Mount Vesuvius Today
Christopher Dimech is a PhD researcher at University College London. We wrote about the Roman eruption of Vesuvius, and the consequences for Pompeii and Herculaneum, on our blog in June. Chris has spent some time at the monitoring station near mount Vesuvius, and here gives us an insight into the kind of research that goes on there. Italy is much better prepared for volcanic hazards today than it ...[Read More]

Geosciences Column: Following Fukushima: what happened to the iodine isotopes?
The March 2011 earthquake, 130 km off the coast of Japan, resulted in a 10-40 m high tsunami inundating Japan’s Pacific coast and caused the release of radionuclides from Fukushima Daiichi Nuclear Power Plant (NPP). The demise of three of the reactors was widely covered in the media, with worldwide coverage of the potential effects of radiation release both close to the plant and further afield. ...[Read More]

GfGD National Conference – Present a Poster
As part of the GfGD National Conference, we would like to give students the opportunity to contribute your ideas on the conference topics, share your research (e.g., MGeol, MSci, MSc, and Mapping Projects), and profile GfGD University Group Activities. This will happen through a poster session. Poster sessions form an important part of many academic conferences. Posters will be displayed throughou ...[Read More]

Imaggeo on Mondays: Capping a volcano
This is Damavand Volcano, Iran. Its history is one of short bursts of eruptive activity followed by long periods of quiescence and while there are active fumaroles near Damavand’s summit, the volcano has been dormant for the past 1000 years. The cloud that encircles its peak is known as a cap cloud, so-called because these peculiar clouds form around high peaks, adding a flat white cap to mountain ...[Read More]

Geosciences Column: How curbing HFC emissions could reduce warming
Carbon dioxide is without a doubt the most famous of warming culprits. But would reducing emissions of this greenhouse gas be enough to mitigate climate change within this century? A recent paper published in Atmospheric Chemistry and Physics focuses on a less known substance that, if phased out, could avoid as much as 0.5 °C of warming by 2100. Hydroflurocarbons (HFCs) have an interesting history ...[Read More]

Geosciences Column: Just a drop in the ocean – river nutrients and Arctic plankton
The oceans are a big contributor to the global carbon cycle, with phytoplankton taking up carbon through photosynthesis and incorporating it into their shells. When these organisms die their shells sink and make a calcareous contribution to seafloor sediments. Of course, with the formation of limestone, this carbon is locked out of the atmosphere for long periods of geological time. Until recently ...[Read More]
