Scales and drivers of temporal

The role of inland waters for the global carbon cycle is now recognized and evidence increasingly suggests that stream ecosystems disproportionately contribute to the carbon cycle. Understanding the dynamics and drivers of stream water partial pressure of ...

Biomineralization in living hypercalcified demosponges: Toward a shared mechanism?

Melany Melissa Gilis

Massive skeletons of living hypercalcified sponges, representative organisms of basal Metazoa, are uncommon models to improve our knowledge on biomineralization mechanisms and their possible evolution through time. Eight living species belonging to various ...

TEM study of Mg distribution in micrite crystals from the Mishrif reservoir Formation (Middle East, Cenomanian to Early Turonian)

Philippe Buffat, Elena Suvorova Buffat

Microporous limestones composed of micrite crystals constitute sizeable hydrocarbon reservoirs throughout the world and especially in the Middle East. However, the crystallization history of micrites is poorly understood. Scanning electronic microscopy (SE ...

Micrometeorological processes driving snow ablation in an Alpine catchment

Michael Lehning, Mathias Thierry Pierre Bavay, Thomas Grünewald

Mountain snow covers typically become patchy over the course of a melting season. The snow pattern during melt is mainly governed by the end of winter snow depth distribution and the local energy balance. The objective of this study is to investigate micro ...

Acidophilic bacteria in Deep Groundwaters of the Bohemian Cretaceous Basin after Extensive Uranium Leaching

Pierre Rossi

The Stráž pod Ralskem region is a part of the Bohemian Cretaceous Basin. The geological profile of the site consists of Quaternary river sediments, Middle Turonian sandstone, Lower Turonian siltstone and Cenomanian collector formed by friable sandstone con ...

Autogenic succession, land-use change, and climatic influences on the Holocene development of a kettle hole mire in Northern Poland

Edward Mitchell, Mariusz Lamentowicz

We reconstructed the Holocene developmental history of a kettle-hole peatland in the Tuchola forest of Northern Poland, using pollen, testate amoebae and plant macrofossils indicators. Our aims were to determine the timing and pattern of autogenic successi ...

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 ...

Atmospheric methane (CH4) records reconstructed from polar ice cores represent an integrated view on processes predominantly taking place in the terrestrial biogeosphere. Here, we present dual stable isotopic methane records [δ13CH4 and δD(CH4)] from four ...

Comment on "greenland-Antarctic phase relations and millennial time-scale climate fluctuations in the Greenland ice-cores" by C. Wunsch

Jérôme Chappellaz, Daniele Romanini

Ancient air trapped inside bubbles in ice cores can now be analysed for methane concentration utilising a laser spectrometer coupled to a continuous melter system. We present a new ultra-high resolution record of atmospheric methane variability over the la ...

Elsevier BV2004

Precise knowledge of the phase relationship between climate changes in the two hemispheres is a key for understanding the Earth's climate dynamics. For the last glacial period, ice core studies have revealed strong coupling of the largest millennial-scale ...
