Seasonal and spatial variation in hydrochemical parameters of Lake Onego (Russia): insights from 2016 field monitoring

Natacha Tofield-Pasche

This study describes seasonal water quality parameters measured in Petrozavodsk Bay, Lake Onego, Russia. Petrozavodsk Bay (PB) lies in the north of Lake Onego and adjacent to the city of Petrozavodsk. PB water quality is controlled by anthropogenic input, ...

Lateral variations and vertical structure of the microbial methane cycle in the sediment of Lake Onego (Russia)

Natacha Tofield-Pasche, Nathalie Dubois

The significance of methane production by lakes to the global production of greenhouse gas is well acknowledged while underlying processes sustaining the lacustrine methane budget remain largely unknown. We coupled biogeochemical data to functional and phy ...

Elastic behavior of partially saturated gas shales during unloading - reloading cycles in uniaxial compression

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Elastic properties of gas shales are of utmost importance for the exploitation of shale gas reservoirs. Static elastic properties are usually measured by performing unloading-reloading cycles in uniaxial or triaxial compressive tests. The response of gas s ...

Seasonality alters drivers of soil enzyme activity in subalpine grassland soil undergoing climate change

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Thomas Spiegelberger, Robert Thomas Edmund Mills

In mountain ecosystems with marked seasonality, climate change can affect various processes in soils, potentially modifying long-term key soil services via change in soil organic carbon (C) storage. Based on a four-year soil transplantation experiment in S ...

Adsorption of thiophene by activated carbon: A global sensitivity analysis

Christian Ludwig

The removal of sulfur compounds in biomass gasification processes is crucial to protect downstream equipment. While conventional sorbent materials can retain H2S, many fail to capture heterocyclic sulfur compounds such as thiophene (C4H4S). This work explo ...
