The Mass has Ended: Colleges, Charity, and Students in the Autumn of the Middle Ages

Since its origins the university was a very privileged institution. The foundation of colleges on the other hand became an important political instrument for penetrating its exclusivity and making learning accessible to students and scholars coming from th ...

Snow-Atmosphere Humidity Exchange at the Ice Sheet Surface Alters Annual Mean Climate Signals in Ice Core Records

Sonja Wahl

Surface processes alter the water stable isotope signal of the surface snow after deposition. However, it remains an open question to which extent surface post-depositional processes should be considered when inferring past climate information from ice cor ...

Seasonality of density currents induced by differential cooling

Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda

When lakes experience surface cooling, the shallow littoral region cools faster than the deep pelagic waters. The lateral density gradient resulting from this differential cooling can trigger a cold downslope density current that intrudes at the base of th ...

Ice Cover and Extreme Events Determine Dissolved Oxygen in a Placid Mountain Lake

Sebastiano Piccolroaz

A decrease in hypolimnetic dissolved oxygen (DO) is a commonly seen effect of climate change. However, in oligotrophic Lake Tovel (Italy), a deep mountain lake, annual mean DO (% saturation) has increased from near anoxia to >20% in the bottom layer (35–39 ...

Influence of Initial Snowpack Properties on Runoff Formation during Rain-on-Snow Events

Michael Lehning, Nander Wever, Sebastian Würzer, Tobias Jonas

Rain-on-snow (ROS) events have caused severe floods inmountainous areas in the recent past. Because of the complex interactions of physical processes, it is still difficult to accurately predict the effect of snow cover on runoff formation for an upcoming ...

Satellite remote sensing of Antarctic sea-ice roughness using scatterometer data

Katherine Colby Leonard, Ernesto Trujillo Gomez

While sea-ice concentration is frequently observed from polar orbiting passive microwave satellite instruments, equivalent large-scale information on sea-ice sub-metre-scale roughness is currently unknown. Roughness on this scale is closely related to sea- ...

Effect of climate change on landslide behaviour

Lyesse Laloui, Alessio Ferrari, John Eichenberger

Landslides represent a major threat to human life, constructed facilities and infrastructure in most mountainous regions of the world. Considering future climate scenarios and modified precipitation patterns, the landslide activity will most probably chang ...

Organic pollutants in compost and digestate. Part 1. Polychlorinated biphenyls, polycyclic aromatic hydrocarbons and molecular markers

Joseph Tarradellas, Rahel Christine Brändli, Reinhard Furrer

In Europe, 9.3 x 10(6) t(dry weight ( dw)) of compost and digestate are produced per year. Most of this is applied to agricultural land, which can lead to considerable inputs of organic pollutants, such as polychlorinated biphenyls ( PCB) and polycyclic ar ...

Organic pollutants in Swiss compost and digestate

Rahel Christine Brändli

Composting (aerobic treatment of organic wastes) and digestion (anaerobic treatment of organic wastes combined with biogas production) are important waste management strategies with increasing significance in the European Union and Switzerland. Most of the ...
