Science Snaps (4): vivid volcanoes

This week we couldn’t just stick to one “Science Snap” so we went for four – one from each of the contributors! We’ve all chosen a volcano dear to our hearts being ones we’ve either visited or studied. James: The giant Uturuncu volcano in southern Bolivia has been slowly uplifting for over 45 years. High-precision GPS and micro-gravimetry in the foreground are b ...[Read More]

The Long Life of Ruzi Mohammed

Ruzi Mohammed thinks that he is around 110 years old. He keeps track of the years using the changing seasons, and there is no missing them in Turtuk, where winters reach -20˚C, and summers are warm and pleasant. Too high for mosquitos, and low enough for a good harvest, Turtuk is a paradise in the summer. The winter is survived by shutting down, almost hibernating, and surviving on wheat mixed wit ...[Read More]

Back to Basics on Groundwater

Back to Basics on Groundwater

When many people hear the word groundwater they imagine a raging underground torrent of water flowing along a pathway called an aquifer. Well, sorry to disappoint you, but you could not be more wrong about how groundwater exists and flows. In this post we will discuss the very basics of groundwater science (hydrogeology) and flow. What is groundwater? As the name implies groundwater is simply wate ...[Read More]

Soils at Imaggeo: when a soil is born

Artemi Cerdà, University of Valencia, Valencia – Spain Soil development is based on the weathering of rocks and the deposition and decomposition of litter and roots, which are the main source or soil organic matter. Mosses are one of the key actors on those processes, as they are present at the initial stages of pedogenesis. This post was also published simultaneously in G-Soil.

Imaggeo on Mondays: Surface spirals

This week’s Imaggeo on Mondays is no ordinary image; it’s a snapshot of surface ocean speeds and the extent of ice cover in the North Atlantic. It was produced using a high resolution model of ocean eddies – high resolution here means that details are simplified into grids 3 km across, or one 20th of a degree. Three kilometres may sound like a pretty large area, but in oceanographic modelling, thi ...[Read More]

Blog Competition (1st Prize) – Robin Wylie: Hydro in India, a Dark Side to the Green Solution

For our Blog Competition 2013, we asked for people to submit articles addressing one of two topics. Robin’s article on the recent floods in Utttarakhand State, India, won first prize in its category. Robin Wylie studied geophysics at the University of Edinburgh, and then spent some time working at a volcanic observatory in Hawaii before starting his Master’s in Earth and Atmospheric Physics ...[Read More]

Abbreviated science

KFC, MTV, BP, BBC, NASA, NHS, UNICEF, FIFA…combinations of letters that are known the world over. These famous examples demonstrate the power of the acronym, a word formed from the initial components of a series of other words. You may have noticed that acronyms in science seem to be everywhere. No grant proposal, research group or society is complete without the obligatory ‘humorous&# ...[Read More]

Friday Field Photos: Eruptions at Lokon-Empung volcano, Indonesia

Friday Field Photos: Eruptions at Lokon-Empung volcano, Indonesia

This week I am at a workshop near the twin-peaked volcano Lokon-Empung, in Sulawesi, Indonesia. True to form (it is the most active volcano in Sulawesi), Lokon has been rather active, with fairly frequent small explosions forming some small but dramatic ash plumes. The active vent is not at the summits of either Lokon, or Empung, but instead at the crater called Tompualan, which lies in the saddle ...[Read More]
