Coffee break biogeosciences – New coral reef at Amazon river mouth discovered

At the Amazon river mouth, a huge 9,300 sq km coral reef system has been found below the muddy waters off the mouth of the river Amazon. As corals mostly thrive in clear, sunlit, salt water, and the waters near the mouth of the Amazon are some of the muddiest in the world, the discovery of this almost 2000 km long reef leaves scientists puzzled about the potential extent of coral reefs worldwide. ...[Read More]

Livers, guts and gills: understanding how organisms become fossils

It’s 10am and Thomas Clements, a 3rd year palaeobiology PhD Student, is getting ready to check on his latest experiment. Full kited up in what can only be described as a space suit, Thomas carefully approaches the fume cupboard home to his latest specimen: a decaying seabass, balanced on a specially designed ‘hammock’ in a tank of salty water. Opening the lid to check on the rotting fish, Thomas i ...[Read More]

Image of The Week – Tumbling Rocks

This photo captures a rockfall at the summit of Tour de Ronde, 3792 m above sea level in the Mont Blanc Massif. On 27 August 2015, around 15000 m3  of rock fell from the steep walls of the mountain. Why do mountains crumble ? Rockfalls such as the one on the photo have been linked to thawing permafrost. The exact mechanism that leads to these events is not fully understood, however, it is thought ...[Read More]

Imaggeo on Mondays: Half dome at sunset

Yosemite’s Half Dome stands, majestic, over a granite dominated terrain in the Yosemite Valley area;  one of the most beautiful landscapes in northern America, and arguably, the world – it is also an Earth scientist’ playground. Stamped into the west slope of the Sierra Nevada range, the Yosemite Valley is a collection of lush forests, deep valleys, meandering rivers and streams, all punctua ...[Read More]

4 ways to have your say

May 13, 2016

A couple of weeks ago, we promised a more detailed review of our experience at the General Assembly 2016. Here is something we deemed worthy to spread word about. EGU is dedicated to geoscience, so the first thing we are all looking for in the general assembly and EGU’s journals is…interesting science! Duh. But science doesn’t live in an isolated space of labs and computing centers. There is ample ...[Read More]

Image of the Week – See How Seasonal Sea Ice Decline Differs!

Why do we care about sea ice in the first place? Sea ice is important for several components of the climate system. Due to its high albedo, sea ice reflects a high amount of the incoming solar radiation and is therefore relevant for the Earth’s energy budget. Sea ice inhibits the exchange of heat, moisture and momentum between ocean and atmosphere, which usually occur at the sea surface. Whe ...[Read More]

New and traditional soil amendments – not so new after all?

Caroline Spann University of Natural Resources and Life Sciences, Vienna As of increasing demands for 4F (food, feed, fiber and fuel production) from agricultural sites there are many researches being done on soil amendments to increase yields, to remediate degraded or even contaminated soils to make them more profitable again. Tuesday morning a session was dedicated to “new and traditional soil a ...[Read More]

Take a deep breath… Or not!

May 12, 2016

We all know that pollution, of any kind, is not good news and that it may lead to health risks. Air pollution, such as smog, is something many large cities experience, especially in low- and middle-income countries. The World Health Organisation reports that “As urban air quality declines, the risk of stroke, heart disease, lung cancer, and chronic and acute respiratory diseases, including a ...[Read More]

The final days of the mountain glaciers

In 1896 British lawyer, mountaineer and author Douglas Freshfield climbed an obscure mountain in the Caucasus called Kasbek and in his book detailing his adventures he described the mountain: “From this point the view of Kasbek is superb: its whole north-eastern face is a sheet of snow and ice, broken by the steepness of the slope into magnificent towers, and seamed by enormous blue chasms.” D Fre ...[Read More]
