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 …[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 …[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 …[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 …[Read More]

Iron volcanism on metallic asteroids?

Francis Nimmo and edited by Antoine Rozel July 10, 2019

This week, Francis Nimmo, professor in the Department of Earth and Planetary Sciences (University of California Santa Cruz), tells us about volcanism on metallic asteroids! Around and after the formation of the solar system (4.5 billion years ago onwards), volcanoes on some of the gigantic bodies of the asteroid belt might have erupted … iron. …[Read More]

NH10 Multi-Hazards: The Latest EGU Natural Hazards Sub-Division

Joel Gill and Marleen de Ruiter July 8, 2019

Earlier this year, the EGU Natural Hazards Division approved the addition of a new sub-division focused on the theme of ‘multi-hazards’. The Science Officers representing this sub-division, Joel Gill (British Geological Survey) and Marleen de Ruiter (IVM-VU Amsterdam), reflect on why this sub-division is necessary and how you can get involved. Many regions are affected …[Read More]
