Glacier Calving – Seismology and Remote Sensing

Glacier calving is a large and important component of glacier mass balance, and moreover is crucial for understanding glacier stability and response to a changing climate. Glacier calving is difficult to quantify as each calving event only last some 10s of seconds.

In this project, you will investigate the use of seismology for better quantification of glacier calving in Svalbard. A number of permanent and temporary seismometers are recording data around glaciers in Svalbard (Ny Ålesund, Longyearbyen and Hornsund).

There are 2 potential study directions within this project:

  • Seismology – Work on detection and analysis of individual calving events from passive seismic data, particularly automated detection and formation of a calving event time series over the duration of a year.

Recommended coures: GEO4620, GEO4280.

  • Remote Sensing – Time-Lapse photography has been used to collect data of a glacier front over a week long period. In this project, we aim to automatically detect calving events from the imagery. Further work will be to connect these visualizations with various styles of calving events and eventually to the seismic signal recorded.

Recommended courses: GEO4420, GEO4520, GEO4530.
