Tostevin-Shields-oxygenLevels

Oxygen Levels were Key to Early Animal Evolution.

A recently graduated doctoral student from our department has just published strong evidence that oxygen levels were key to early animal evolution. Dr Rosalie Tostevin (now at Oxford University) was supervised by Professor Graham Shields-Zhou in a project studying some of the world’s oldest animal-based reef ecosystems in Namibia. Over the course of her PhD, she looked at various chemical tracers of oxygen, before settling on a unique combination of iron speciation, rare earth elements and sulphur isotopes. The study has been widely reported as the first one that is able to distinguish between bodies of water with low and high levels of oxygen (not simply distinguishing oxic from anoxic waters).  Rosalie shows in her work, published in Nature Communications, that poorly oxygenated waters did not support the complex life that evolved immediately prior to the Cambrian Period, suggesting the presence of oxygen was a key factor in their appearance.

EarthSciences Arctic Meeting

Understanding the Arctic.

The Arctic has undergone some of the most rapid transformations over the past 50 years, with global implications for the Earth’s climate. A dramatic indicator of Arctic climate change is the shrinking summer sea ice cover. Recently Arctic sea ice loss has accelerated with the ten lowest minima sea ice extents (SIE) all occurring in the last ten years, and the Arctic is now expected to become ice-free during summer at some point this century.  More...

2016-Campi Flegrei

Drilling into a supervolcano.

The Campi Flegrei volcanic complex, in southern Italy, is showing its first signs of unrest for more than 400 years. The Deep Drilling Project promises exciting new information about the state of the volcano. A team from the UCL Hazard Centre is working with colleagues at the Vesuvius Observatory to discover where and when another eruption can be expected. As team leader Dr Christopher Kilburn explains: “We are studying Campi Flegrei, not only to advance science, but also to protect the 300,000 people living across the volcano.” More...

Mars river - Aram Dorsum

Fossilised rivers suggest warm &wet ancient Mars.

Extensive systems of fossilised riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea that the now cold and dry Red Planet had a warm and wet climate about four billion years ago,  More...

Mount St Helen Study

Studies of lava spines at Mount St. Helens volcano.

The explosive potential of volcanoes is primarily controlled by the quantity of gas in the magma and its ability to escape. Gas can escape from solidified magma through a network of interlinked cracks, and the ease of escape in this way is known as the permeability. In a recent paper published by Gaunt et al. in Bulletin of Volcanology, studies of lava spines at Mount St. Helens volcano, have revealed that although these fracture-networks are relatively permeable at room temperature, at elevated temperatures such as those found in volcanic conduits, this permeability can be substantially reduced. This results was not expect and means that the permeability and explosion potential can change dramatically with changing environmental conditions. More...
