Goodbye…… for now

Goodbye…… for now

After 3 years of blogging, (can you believe Jenga has been going for 3 years already?!), the time has come to wave goodbye to the EGU Blog network. Dan and I have very much enjoyed being part of this active, fun and engaging community of geoscience bloggers. However, our circumstances have changed signifiantly since we embarked on this journey. We no longer work at the same Univeristy, nor are we ...[Read More]

Imaggeo on Mondays: Rock glaciers

Imaggeo on Mondays: Rock glaciers

Picture a glacier and you probably imagine a vast, dense mass of slow moving ice; the likes of which you’d expect to see atop the planet’s high peaks and at high latitudes. Now, what if not all glaciers look like that? Take some ice, mix in some rock, snow and maybe a little mud and the result is a rock glacier. Unlike ice glaciers (the ones we are most familiar with), rock glaciers have very litt ...[Read More]

Monday paper: The challenge and future of rocky desertification control in karst areas in southwest China

Zhang, J. Y., Dai, M. H., Wang, L. C., Zeng, C. F., and Su, W. C. 2016. The challenge and future of rocky desertification control in karst areas in southwest China. Solid Earth, 7:83-91, DOI:10.5194/se-7-83-2016, 2016.   Karst ecosystems in China are one of the main objectives of desertification control, since its conservation is important for economic and social development, especially of th ...[Read More]

The smallest volcanic island in the world?

The smallest volcanic island in the world?

One of the delights of talking to children of primary school age is their disarming ability to ask really simple questions that demand straightforward answers, but leave you struggling to throw your academic caution to the wind. Even with the questions of the biggest, the smallest, the oldest and the youngest there are still different ways of (over)interpreting the question, that can leave you flo ...[Read More]

Geosciences Column: The World’s soils are under threat

Geosciences Column: The World’s soils are under threat

An increasing global population means that we are more dependant than ever on soils. Soils are crucial to securing our future supplies of water, food, as well as aiding adaptation to climate change and sustaining the planet’s biosphere; yet with the decrease in human labour dedicated to working the land, never have we been more out of touch with the vital importance of this natural resource. Now, ...[Read More]

Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

As climate change progresses, widespread changes in phenotypes in many plant populations are bing observed by scientists around the world. For instance in alpine areas, dominant plant species on lower altitude are shifting towards higher altitude as they adapt to increasing temperatures, thereby competing with high-altitude native plant species. In a recent study by Petry et al. (2016) it was show ...[Read More]

Image of the week – The winds of summer (and surface fluxes of winter)

Antarctica is separated from the deep Southern Ocean by a shallow continental shelf. Waters are exchanged between the deep ocean and the shallow shelf, forming the Antarctic cross-shelf circulation: Very dense waters leave the shelf as Antarctic Bottom Water (AABW) that will then flow at the bottom of all oceans. Meanwhile, relatively warm water from the Southern Ocean, Modified Circumpolar Deep W ...[Read More]

Imaggeo on Mondays: an impressive testimony to the collision between Africa and Europe

Imaggeo on Mondays: an impressive testimony to the collision between Africa and Europe

The huge fold in the flank of the 2969 m high Dent de Morcles (in Waadtland Alps, Switzerland) is an impressive testimony to the collision between Africa and Europe (which began some 65 million years ago). The layers, originally deposited on the sea floor in a horizontal position, were compressed and shifted. The darker parts developed during the Tertiary period (66 million years ago). They are yo ...[Read More]
