From space, the Brandberg Igneous Complex looks like a coffee-coloured birthmark set upon the bony complexion of the Namibian desert. Perfectly circular, its peaks soar in a ring of mighty topography, its massive granite cliffs etched with the muscular definition of spheroidal weathering.

Imaggeo on Mondays: Carving polar canyons
This week Ian Joughin, a research scientist from the Polar Science Center at the University of Washington, takes us on the polar express to put glacial processes into perspective and find out what makes a moulin… This canyon formed when a melt lake on the surface of the Greenland Ice Sheet overflowed and created a stream that extended out toward a crevasse field. This outflow stream filled a creva ...[Read More]

Monday paper: Managing soil nitrate with cover crops and buffer strips in Sicilian vineyards
A. Novara, L. Gristina, F. Guaitoli, A. Santoro, A. Cerdà. 2013. Managing soil nitrate with cover crops and buffer strips in Sicilian vineyards. Solid Earth, 4, 255-262, doi:10.5194/se-4-255-2013 Abstract When soil nitrate levels are low, plants suffer nitrogen (N) deficiency but when the levels are excessive, soil nitrates can pollute surface and subsurface waters. Strategies to reduce the nitrat ...[Read More]
