Two laboratory experiments are used to provide preliminary evidence towards upscaling the microbially induced calcite precipitation (MICP) for soils. Fine sand is packed and subsequently subjected to MICP treatment in 11-liter cylindrical tanks. Different ...
Changes in seawater chemistry have affected the evolution of calcifying marine organisms, including their skeletal polymorph (calcite versus aragonite), which is believed to have been strongly influenced by the Mg/Ca ratio at the time these animals first e ...
The Great European Lake Onego provides important resources for Northern Russia. This lake is ice-covered during 5 months in winter. However, very few data are available for winter, as most studies covered the ice-free period. Actually, comprehension of sea ...
Deep saline aquifers have a great potential for geologic carbon dioxide (CO2) sequestration and proper assessment of host and cap rock is needed to guarantee that the procedure is safe. Temperatures and pressures at which most of the possible host rocks ex ...
Waters were sampled monthly from a profile at the wastewater outlet and a reference point in the Bay of Vidy (Lake Geneva) for a year. The samples were analyzed for O-18/O-16 of water, C-13/C-12 of dissolved inorganic carbon (DIC), major ions, and selected ...
Species of Haliotis ~abalone! show high variety in structure and mineralogy of the shell. One of the European species ~Haliotis tuberculata! in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
Lake Geneva (Lac Léman) is the largest freshwater body in Western Europe. It is a deep peri-alpine lake whose importance stems from being not only an essential freshwater source in the region, but also a major tourist destination, a fishery and a waterway. ...

Between 1920 and 1967, approximatively 8000 tons of ammunition waste was dumped into some Swiss lakes. Previous studies based on grab sampling revealed small traces of cyclotetramethylenetetranitramine (HMX), cyclotrimethylenetrinitramine (RDX) and pentaer ...
Fluid-rock interactions can control earthquake nucleation and the evolution of earthquake sequences. Experimental studies of fault frictional properties in the presence of fluid can provide unique insights into these interactions. We report the first resul ...
