Talking hydrology: an interview with Hjalmar Laudon on hydrological research at the Krycklan catchment

EGU Guest blogger July 17, 2019

For our second post of “Talking hydrology”, we interviewed Hjalmar Laudon, professor and chair of forest landscape biogeochemistry at SLU Umeå (Sweden). We talked about past and current research in the Krycklan catchment and the usefulness of long-term datasets. 1) You have been conducting hydrological research at the Krycklan catchment (North of Sweden) since 2002. How did you keep yoursel ...[Read More]

Imaggeo on Mondays: The surprising beauty of the Arctic tundra

Alexandra Loginova July 15, 2019

Close your eyes and try to imagine first thing which comes to your mind, when somebody says “Tundra”. What would you imagine? Being a master student, I imagined cold, flat and a dead field. In fact, Tundra turn out to be completely different, at least in September 2010, when I and my colleagues were lucky to visit it. As it is well known from textbooks no big trees grows in Tundra, how ...[Read More]

#mineralmonday : lithiophilite

Mike Jollands July 15, 2019

What is it? Lithiophilite, LiMnPO4 What’s it made of? Lithium (Li), manganese (Mn), phosphorus (P) and oxygen (O). The PO4 at the end of the formula makes this a phosphate mineral (phosphorus + oxygen = phosphate). What’s it’s structure? The way the different atoms are arranged in lithiophilite is described as orthorhombic, which means the crystal is built of lots of tiny cuboid- ...[Read More]

Geosciences Column: How erupting African volcanoes impact the Amazon’s atmosphere

Olivia Trani July 12, 2019

When volcanoes erupt, they can release into the atmosphere a number of different gases initially stored in their magma, such as carbon dioxide, hydrogen sulfide, and sulfur dioxide. These kinds of gases can have a big influence on Earth’s atmosphere, even at distances hundreds to thousands of kilometres away. A team of researchers have found evidence that sulfur emissions from volcanic eruptions i ...[Read More]

Careers in Geoscience-for-Development: Some Tips and Resources

Dr Joel C. Gill July 12, 2019

One of the most frequently asked questions put to me is ‘how does a geoscientist develop a career linked to international aid or sustainable development?’. Here are some thoughts, recently curated for the 2018 GfGD Annual Conference report, together with examples of how GfGD’s work helps to mobilise geoscientists to engage in sustainable development. Geoscience matters, is critical to progre ...[Read More]

Beyond tectonics: The present-day tides are the biggest they have been since the formation of Pangea

Hannah Davies July 12, 2019

“Beyond tectonics” is a blog series which aims to highlight the connections between tectonics and other aspects of the Earth system. In this iteration of the “Beyond tectonics” series we talk about how plate tectonics have affected the tides on Earth over geological timescales. We will talk about tectonics on the Earth since the formation of Pangea to the present day, and i ...[Read More]

Slimy Landscapes 2: This time it’s Precambrian

Chris Skinner July 11, 2019

Slime is important to the developments of Earth’s landscapes – I have already explored this in a previous post where I learnt how Extracellular Polymeric Substances (EPS), a fancy phrase for a slime produced by organisms, can bind sediments together and making them resistant to erosion. This has impacts on the development of landscapes, from the types of bedforms forming below flows, the rate at w ...[Read More]
