Benefits and drawbacks of applied direct currents for soil improvement via carbonate mineralization

Lyesse Laloui, Dimitrios Terzis, Patrick Gabriel Yihsiu-Ming Hicher

The study presented herein adopts a new vision of the processes involved in carbonate mineralization induced by MICP from an electrochemical and crystal growth perspective. More precisely a specific line of focus refers to the species involved in the bio-c ...

Toward a systematic integration of optical remote sensing for inland waters studies

Vincent Maurice Nouchi

Freshwater resources play a central role in social and economic development of modern civilisations, yet their value is often underestimated and neglected in developed countries. In fact, freshwater habitats are facing unprecedented threat because of human ...

Aragonitic scleractinian corals in the Cretaceous calcitic sea.

Anders Meibom, Jaroslaw Hubert Stolarski, Stéphane Laurent Escrig

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 ...

Stable carbon and oxygen isotope compositions of extant crinoidal echinoderm skeletons

Anders Meibom, Jaroslaw Hubert Stolarski

The variability of delta C-13 and delta O-18 was determined within the columnal facet of individual ossicles, within different regions of skeletons and within bulk skeletons of extant stalked crinoids. Isotopic compositions of individual ossicles may vary ...

26Mg labeling of the sea urchin regenerating spine: Insights into echinoderm biomineralization process

Anders Meibom, Jaroslaw Hubert Stolarski, Christophe Kopp

This paper reports the results of the first dynamic labeling experiment with regenerating spines of sea urchins Paracentrotus lividus using the stable isotope Mg-26 and NanoSIMS high-resolution isotopic imaging, which provide a direct information about the ...

A Cretaceous scleractinian coral with a calcitic skeleton

Anders Meibom, Jaroslaw Hubert Stolarski

It has been generally thought that scleractinian corals form purely aragonitic skeletons. We show that a well-preserved fossil coral, Coelosmilia sp. from the Upper Cretaceous (about 70 million years ago), has preserved skeletal structural features identic ...

Calcite dissolution in two deep eutrophic lakes

Alfred Johny Wüest, Bernhard Wehrli

The calcium cycle, in particular carbonate dissolution, was analyzed in two deep eutrophic lakes, Lago di Lugano (288 m maximum depth) and Sempachersee (87 m) located in Switzerland. A box model approach was used to calculate calcite dissolution in the wat ...

Typologie géochimique des eaux des aquifères carbonatés des chaînes alpines d'Europe centrale et méridionale

This study describes the spatial heterogeneousness of the chemical composition of underground waters, particularly the trace elements, and the carbon-13 isotope in several carbonate aquifers of the alpine belt in Europe. The research forms part of the AQUI ...
