Studienarbeiten Glaziologie
Laufende Forschungsprojekte aus der Professur für Glaziologie bilden die Grundlage für angebotene Bachelor- und Master-Arbeiten. Die Themen richten sich hauptsächlich an Studierende der Fachrichtungen Erdwissenschaften, Umweltwissenschaften, Physik, Rechnergestützte Wissenschaften wie auch Umweltingenieurwissenschaften, Raumbezogene Ingenieurwissenschaften und Bauingenieurwissenschaften. Studierende, die sich für eines der Themen interessieren, sind angehalten die unter „Contact Details“ angegebenen Personen (siehe einzelne Projektbeschreibungen, unten) zu kontaktieren bevor eine Registrierung im ETH myStudies-Portal erfolgt.
Die ETH Zürich verwendet externe Seite SiROP um wissenschaftliche Projekte auszuschreiben. Darin sind folgende Themen aus der Glaziologie erfasst (Detailbeschreibungen sind nur in englischer Sprache verfügbar):
Modelling the Future of Glacier Skiing in High-Altitude Alpine Resorts
Glaciers worldwide are retreating due to climate change, leading to diverse consequences such as sea level rise, changes in water availability, increased natural hazards, and disruptions to tourism. In the European Alps, glaciers are a key attraction, drawing millions of visitors annually. One of the touristic attractivities of glaciers is their role in skiing. However, climate change in and especially recent extreme negative mass balance years have significantly impacted summer skiing (e.g., Abegg and Mayer, 2023). This MSc project aims to assess the effects of climate change on glacier-based ski resorts across the Alps. Potential study sites include Hintertux, Les Deux Alpes, Saas Fee, and Tignes, though other locations may also be considered.

Background
Glaciers worldwide are retreating due to climate change, leading to diverse consequences such as sea level rise, changes in water availability, increased natural hazards, and disruptions to tourism. In the European Alps, glaciers are a key attraction, drawing millions of visitors annually. One of the touristic attractivities of glaciers is their role in skiing. However, climate change in and especially recent extreme negative mass balance years have significantly impacted summer skiing (e.g., Abegg and Mayer, 2023). This MSc project aims to assess the effects of climate change on glacier-based ski resorts across the Alps. Potential study sites include Hintertux, Les Deux Alpes, Saas Fee, and Tignes, though other locations may also be considered.
Goal
The goal of this MSc thesis is to apply an ice flow and mass balance model (Van Tricht and Huybrechts, 2023) to various Alpine glaciers that host ski resorts. Using existing models, ice thickness datasets, satellite imagery, mass balance observations, ski resort maps, and meteorological records, the research will simulate historical and future glacier evolution under climate change while accounting for the impact of ski resort activities.
Methodology & Workflow
- Familiarisation with the mass balance and ice flow model.
- Data Collection, including: o Satellite data (snowlines) o Ice thickness measurements and reconstructions (what is available, should we collect?) o Meteorological records o Historical observations o Information from ski resorts (closing dates of the resorts, piste locations)
- Model Adaptation to incorporate artificial snowmaking and snow farming (similar to tarps).
- Model Execution & Evaluation of glacier mass balance and ice flow dynamics.
- Future Simulations considering climate change scenarios and ski resort impact.

Consolidating parameterizations of wind-driven snow accumulation over glaciers
Accurate modelling of glacier mass balance requires the representation of wind-driven snow transport. This thesis will investigate the performance of various parameterizations.

Beschrieb
Accurate modelling of glacier mass balance requires the representation of wind-driven snow processes. Yet, the physical representation of these processes is computationally too expensive to include in standard mass balance models and, therefore, requires simplification via parameterization schemes.
Ziel
This thesis will compare existing but not widely used parameterizations for different climatic regions (continental Alpine glaciers, maritime glaciers in New Zealand, and seasonal snow cover). The aim is to consolidate existing parameterizations for applications in standard energy and mass balance models.

West Antarctic Ice Sheet subglacial drainage and grounding zone seismicity
Antarctic ice sheets contribute significant uncertainty to sea level rise projections due to processes occurring deep beneath the ice. This project will use existing data from two passive seismic deployments to investigate the ice sheet – ice shelf transition of Kamb Ice Stream in West Antarctica.

Beschrieb
Antarctic ice streams feed approximately 90% of Antarctica’s ice into the world’s oceans. These ice streams flow to the ocean through a combination of internal deformation and by sliding over and deforming the rock and sediment that underlies them. Processes at the base of the ice are particularly important to understand as they can result in rapid changes in ice flow velocity at time scales of hours to days and years to centuries. Many of these processes emit acoustic signals which can be recorded at the ice surface making passive-source seismology an ideal tool with which to study them. This project will use existing data to examine the transition where the grounded Kamb Ice Stream crosses into the Ross Ice Shelf and contributes to global sea level.
Ziel
Project aims include identifying, locating, and characterising seismicity from sources at the base of the ice stream and within the ice shelf. These sources include water flow in a large subglacial drainage channel, and crevasse formation due to flexure of the floating ice shelf as it rises and falls with the tide. To achieve the aims you will use existing tools (e.g. obspy) to process and analyse the data. Basic programming skills, or the desire to develop them, are required. The ideal candidate would also have an interest in glaciology and applied geophysics. Should time allow, the results will be compared with other complementary data (e.g. Global Navigation Satellite System positioning) and model output (e.g. subglacial water routing.)
