Featured catchment: Hydrometeorological observations in an agricultural landscape in the Czech Republic

The Nučice experimental catchment (0.531 km2) is located 30 km east of Prague in an agricultural landscape in the Central Bohemian Region, Czech Republic (Figs. 1 and 2). The cultivated landscape and climatic conditions are representative of farmlands of the Czech Republic. To understand water balance, rainfall-runoff and soil erosion processes on the cultivated landscape, we started hydrological ...[Read More]

Imaggeo On Monday: Yardangs in the Gobi desert

Seeing the Yardang rock formations during sunset was a surreal experience. While they seem to have be standing in a sea of water that formed them, the fluid dynamics that actually lead to their existence is the result of wind abrasion by dust and sand and the removal of loose material by wind turbulence. The air flow and resulting pattern of erosion and the distribution of rocks determines their s ...[Read More]

When carbon emissions break nature: icebergs and their feedback to climate change

The largest iceberg in the world, named A-76, about 170 km long and 25 km wide, is drifting away from the Ronne pack ice in Antarctica. A76, originally spotted by the British Antarctic Survey (BAS), a British polar research organization with a base nearby, will wander and melt in the Weddell Sea, according to a statement released Wednesday, May 20, by the European Space Agency. Several studies are ...[Read More]

It’s not you, it’s me(lange): ice shelf break-up triggered by mélange and sea-ice loss

Between March and May 2007, a total of ~2,445 km2 (equivalent to over 17 football pitches) of ice mélange (a mixture of sea-ice types, icebergs and snow) and part of Voyeykov Ice Shelf in East Antarctica rapidly broke up. Observations of the timing and triggers of such events are relatively rare in East Antarctica, compared to ice shelves on the Antarctic Peninsula. Recent work highlights the impo ...[Read More]

The importance of our SSS (…Soil Support Staff!) #6

It’s May, and here at Soil System Science HQ we’re calming down after a busy yet fascinating fortnight at the General Assembly. Over the course of two weeks, we enjoyed many thousands of soil science presentations – each one representing a great contribution to our knowledge and understanding about the soil system. Of course, we should never forget that much of that research would not have b ...[Read More]

The Supercontinent Cycle

From orbital, to climatic, to tectonic evolution, many aspects of the Earth’s dynamics feature high degrees of cyclicity and episodicity, which can give us important insights into how the Earth’s works. The supercontinent cycle is an example capturing the Earth’s grandest scales and this week EGU geodynamics blog editor Tobias Rolf takes a closer look at it. Pangaea. This is a familiar term to eve ...[Read More]
