GEO Colloquium
Our GEO Colloquium is a series of overarching seminar talks to bring together students and staff members from all research units at the department in person. Find a list of all talks so far below:
- Markus Rothacher, Prof. em. ETH Zürich, Mathematical and Physical Geodesy, Switzerland, Cubesat-constellation with low-cost multi-GNSS receiver, 5 October 2022, at 13:45 in FH HS 8 (Freihaus, 2nd floor, yellow area)
- Daniel R. Montello, professor at the Departments of Geography and Psychological & Brain Sciences, University of California, Santa Barbara, USA, The Study of Cognition in Geographic Information Science, 30 May 2022
- Abstract: Geographic information scientists (GIScientists) study representations of the earth and its human and natural structures and processes, as depicted in words, numbers, pictures, and possibly other formats. Cognitive scientists study knowing and knowledge in humans, nonhuman animals, and sentient machines. This includes perception, thinking, reasoning, problem solving, memory, attention, and language. In this talk, I consider theoretical and practical reasons why the study of cognition matters to GIScience and GISystems. I present research my colleagues and I have conducted that explores the intersection of geographic information and cognition. In this way, I show that GIScience is, in part, a cognitive science.
- Chris Rizos, professor at the University of New South Wales, Australia, past president of the International Association of Geodesy (IAG), president-elect of the International Union of Geodesy and Geophysics (IUGG), What MORE can Geodesy do for the Geosciences, 5 April 2022
- Jelena Gabela, PostDoc at Engineering Geodesy at TU Wien, Position integrity for road based applications, 17 January 2022
- Michael Schindelegger, Professor for Geodetic Earth System Science at the University of Bonn, Caprices of coastal sea level, 11 October 2020
- Abstract: Coastal sea level is a key variable in climate and coastal process studies and for managing flood risks in dynamic human and natural environments. Embedded in the spectrum of non-tidal coastal sea level signals from sub-daily to secular time scales are large (order ~10 cm) seasonal to interannual variations that are set by a multitude of physical processes, e.g., winds, river runoff, boundary currents, and topographic conditions. Given their tendency for acting on short scales in cross-shore direction, these low-frequency fluctuations have been difficult to observe, as tide gauges are geographically sparse and conventional altimetry retrievals are degraded
30 km from land. New altimetry technologies and reprocessed products, used in conjunction with ocean models, hold the promise of shedding more light on these intriguing signals. Here I give an overview of our understanding of seasonal to interannual coastal sea level variability, the role of boundary trapped waves and river plumes, and the current limitations of both models and observations used in that context. Results are mainly taken from an ongoing, multi-headed student’s Master Project, conducted at my home institution under the same title as this presentation.
