Christian Filbrandt

Christian Filbrandt serves as a Researcher in Topic 3 within the Dynamics of the Ocean Floor division at GEOMAR Helmholtz Centre for Ocean Research Kiel, specializing in Marine Geodynamics. His work focuses on deploying and maintaining ocean floor monitoring systems including Ocean Bottom Seismometers (OBS) and Ocean Bottom Hydrophones (OBH).

Education:

• M.Sc. Geophysics (2019-2023) from Kiel University (Christian-Albrechts-Universität zu Kiel) with thesis: 'Examination of hydroacoustic Data for characterisation of AirGun Arrays, Noise in the Ocean and for quality control'
• B.Sc. Physics of the Earth System (2015-2020) from Kiel University

His research integrates fieldwork with hydroacoustic data analysis to study ocean floor dynamics, noise characterization, and seismic monitoring systems. Filbrandt participates in international research expeditions across Atlantic and Southern Ocean regions, deploying geophysical instrumentation for long-term monitoring of tectonic activity and oceanographic processes. His technical expertise includes airgun array maintenance, multibeam sonar operation, and pressure sensor deployment.

Expedition Experience:

• RV Sonne SO301 (2023-2024): OBS deployment/recovery
• Meteor M204 (2024): Geodesy station recovery
• Multiple expeditions (2018-2023) involving OBS/OBH systems across Atlantic, Mediterranean, and Southern Ocean regions

Working within GEOMAR's Research Unit Marine Geodynamics, Filbrandt contributes to projects examining seafloor deformation, volcanic activity, and ocean-atmosphere interactions through advanced geophysical instrumentation and data analysis techniques.
