Soils going red: Terra rossa

From Wednesday to Saturday 9-12 September 2015, the geography departments of the Universities of Bonn/Germany and Salzburg/Austria, held a joint field course in geomorphology in the eastern European Alps. During these four days, 24 students master students, half from each participating university, gathered in Gmunden, Austria. Here, in the beautiful Salzkammergut, the course addressed topics of ge ...[Read More]

Happy new year, EGU deadline

Happy new year ! After all the extra food and booze the holidays bring along, many by now would have returned back to their desks planing the new year targets and deadlines. First on the list is probably the EGU abstract submission deadline on the Thursday 16 January, 13:00 CET. A session you might find of interest is SM1.7/EOS17: Seismological and Geophysical Apps. This session focuses on the use ...[Read More]

Monday paper: Comparing soil biogeochemical processes in novel and natural boreal forest ecosystems

by Daniel Keszthelyi Physics of Geological Processes group at the Department of Physics, University of Oslo Over 40 years of oil production from the Ekofisk field caused the overlying seafloor to sink over 9 meters during the years and while there have been numerous researches on the topic; the clear understanding of what happens with the reservoir rocks during production is still missing. We crea ...[Read More]

Short time for submitting abstracts to the EGU2014 Programme on Soil Science

This post is written by Matt Herod, and reposted here with permission… A recently published paper (by myself and colleagues from uOttawa and Environment Canada) investigates the environmental fate of the long lived radioisotope of iodine, 129I, which was released by the Fukushima-Daichii Nuclear Accident (FDNA). Within 6 days of the FDNA 129I concentrations in Vancouver precipitation increas ...[Read More]

It needn’t be Hell with soil

This is one of the pictures the year has left. In it, two Muslim militiamen armed with machetes are registering a Christian in the Miskine neighborhood, in Bangui (Central African Republic), December 13, 2013. About 1,600 and 3,000 French soldiers already there of the African MISCA international mission were not able to stop violence and chaos. Both in this case and in other armed conflicts, there ...[Read More]

Monday paper: A dual isotope approach to isolate soil carbon pools of different turnover times

Torn, M. S., Kleber, M., Zavaleta, E. S., Zhu, B., Field, C. B., Trumbore, S. E. 2013. A dual isotope approach to isolate soil carbon pools of different turnover times. Biogeosciences, 10, 8067-8081. DOI: 10.5194/bg-10-8067-2013. Abstract Soils are globally significant sources and sinks of atmospheric CO2. Increasing the resolution of soil carbon turnover estimates is important for predicting the ...[Read More]

Cold soil in the groove

Often, soils from cold regions, such as Arctic soils, show polygonal forms in their surface. These polygons are formed because of the freeze-thaw cycle, characteristic of permafrost. What is permafrost? Permafrost is a subsurface soil layer which stays permanently frozen (below 0 oC) during long periods of time, usually more than two consecutive years. Most extensive permafrost areas can be found ...[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]
