That landslides are hazardous goes without saying; the risk posed by them will largely depend on where they occur and their exact characteristics, which makes understanding the mechanisms which trigger them, as well as predicting when they might happen, extremely difficult. Today’s Imaggeo on Mondays image, brought to you by Ekrem Canli, a PhD student at the University of Vienna, is an example of ...[Read More]
So it has been a while since I last blogged, attributed to various excuses – fieldwork, moving job, moving house – but moving forwards I intend to spend more time discussing the myriad aspects of geoscience I find fascinating. One good example is a recent paper from Janice Brahney (University of British Columbia) and colleagues in Global Biogeochemical Cycles entitled ‘Is atmospheric p ...[Read More]
The adoption of legislation within the European Union (EU) is a complex process involving many steps. In my first blog post in this GeoPolicy series I highlighted an example of this process. Several draft legislation pieces are currently being assessed within the European Parliament (EP) and Council of Ministers (Council) that have been influenced by EGU-related science. This blog post summarises ...[Read More]
This illustration shows two Synthetic Aperture Radar (SAR) images taken over sea ice in the Arctic Ocean. Both images are polarimetric and the different colours reflect the different polarimetric channels of the SAR (red = VV, green = HV and blue = HH). The two images are from the two satellites “ALOS-2” and “RADARSAT-2”. These are equipped with radars that operate at wavel ...[Read More]
My Antarctic adventure started from Punta Arenas at the bottom of Chile, opposite Tierra del Fuego, on New Years Eve 2014 after a long journey from Heathrow via São Paulo and Santiago. Punta Arenas Punta Arenas is where Shackleton organised the rescue of his men from Elephant Island after his voyage to South Georgia in the James Caird. It is also where I met my PhD supervisors Chris Fogwill and Ch ...[Read More]
The Spanish-Portuguese Assembly of Geodesy and Geophysics meets every two years alternatively between the two countries, Spain and Portugal. Throughout the different editions, the assembly has consolidated a forum for research in the fields of Geodesy, Seismology, Meteorology, Geomagnetism, Hydrology, Oceanography, Volcanology, Cryospheric Sciences and Applied Geophysics, and it has given continui ...[Read More]
Cecilia Reed (aka Lady Rock) is a volcano and geology enthusiast, film-maker and communicator based in London, UK. She has previously published a really interesting series of videos relating to volcanic activity, culture and the local environment in Central America. Cecilia has kindly allowed us to republish this post from her Tumblr site, introducing her latest video series and reflecting on the ...[Read More]
This week’s photo is brought to you from outer space! Indeed, this a beautiful cut section of a meteorite that fell in northwest Australia and was found in 1892 (ignore the label behind it). It is an iron-nickel meteorite and is composed entirely of metal. This crazy cross-hatching, which is most commonly found in such iron-nickel meteorites, is called a Widmanstätten pattern. Widmanstätten ...[Read More]
In addition to the usual GeoTalk interviews, where we highlight the work and achievements of early career researchers, over the next few months we’ll be introducing the Division early career scientist representatives (ECS). They are responsible for ensuring that the voice of EGU ECS membership is heard. From organising short courses during the General Assembly, through to running Division Blogs an ...[Read More]
It is once again time to write about geology and classics and the incredibly important impact the geosciences had on the ancients and their way of life. My previous post on this topic can be found at my old blog location as the post: The Odyssey and Geology. I’ll begin by relating a story: The two fleets, the Persians the the Greeks, which was composed of the navies of all the city states, b ...[Read More]
