How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Introduction
My scientific work is dedicated to thermal conditions of the shallow subsurface. With my research I try to answer questions like: Does climate change pose a threat on our groundwater resources? How do local anthropogenic heat emissions accumulate to large-scale subsurface urban heat islands? And can we recycle this waste heat to reduce stress on natural ecosystems and reduce carbon emissions?

Meeting the rising energy demands of cities is a global challenge. Exploitation of the additional heat in the subsurface associated with the subsurface urban heat island (SUHI) has been proposed to address the heating demands. For the sustainable use of this heat it is crucial to understand how SUHIs evolve. To date, there have been no comprehensiv...

Anthropogenic warming of the atmosphere is one if not the most pressing challenge we face in the 21st century. While our state of knowledge on human drivers of atmospheric warming is advancing rapidly, little so can be said if we turn our view toward the Earth’s interior. Intensifying land use and atmospheric climate change condition the changing t...

Quantification of the isotope altitude effect from precipitation allows to identify recharge altitudes in high-relief areas. However, steep terrains frequently limit the possibility of this precipitation-based approach. Perennial rivers often provide easy, year-round access for water sampling. However, in high-relief regions rivers may not adequate...

Thermal use of the shallow subsurface and its aquifers (< 400 m) is steadily increasing. Currently, more than 2800 aquifer thermal energy storage (ATES) systems are operating worldwide alongside more than 1.2 million ground source heat pump (GSHP) systems in Europe alone. These rising numbers of shallow geothermal energy (SGE) systems will put addi...

Thermodynamic coupling between atmosphere and ground yields increasing aquifer temperatures as a consequence of global warming. While this is expected to manifest as a gradual warming in groundwater temperature time series, such continuous long-term recordings are scarce. As an alternative, the present work examines the use of repeated temperature-...

Subsurface temperature data is usually only accessible as point information with a very limited number of observations. To spatialize these isolated insights underground, we usually rely on interpolation methods. Unfortunately, these conventional tools are in many cases not suitable to be applied to areas with high local variability, like densely p...

The high-relief catchment of the Tavignanu River (Corsica Island, France) with an elevation range from sea level to 2622 m above sea level was investigated for its riverine carbon budget and stable carbon isotopes. Major riverine dissolved inorganic carbon (DIC or TCO2) sources depended on seasons and sub-catchment lithology. In winter δ¹³CDIC valu...

Kurzfassung Während des Maximums der Würm-Eiszeit bestand im Südschwarzwald eine Vergletscherung des norwegischen Typs mit einer Eiskappe, deren Zentrum im Bereich des Feldbergs lag. Von dort erstreckten sich bis zu 25 km lange Talgletscher. Im Gegensatz dazu waren Nord-und Mittelschwarzwald hauptsächlichhauptsächlich durch Karvergletscherungen, mi...
