Advanced marine geophysical survey project

Marine geophysics is a core field in the geosciences training in the Bachelor (e.g. Module Marine Geophysics, Seismic Exploration/Processing) and Master programs (e.g. Advanced Geophysical Exploration, Seismic/Acoustic Imaging, Angewandte Geophysik, Geophysics of the Ocean Crust, Gas Hydrates, ...) in Bremen. An essential component is field practice, which requires access to research vessels.

For advanced training within the master programs, ship time on R/V Alkor is available in late summer 2022.
Preliminary date of the R/V ALKOR cruise:
12.09.2022 - 26.09.2022
Within this time frame, 6-7 days are available for the course.

This leg will be dedicated to specific research objectives, e.g. in the Kattegatt and the Gotland Basin as preliminary working areas, which will be developed with participants during the preparatory phase (August/September) before the cruise. Literature review, a seminar presentation and a discussion round shall lead to a scientific working program, which is guided by current research themes in these areas.

The cruise will operate on a 24 hour schedule with typical watchkeeping schemes. The group of participants is responsible to collect information about instruments, data acquisition and preliminary results and shall participate in planning,onboard processing and data review. As part of the exam, a professional cruise report is to be provided 2 weeks after the cruise.

Subsequenctly, each participant is responsible for a small project (appx. 2 weeks) on the acquired data to answer a specific scientific question, which will be identified during the cruise. Training on required data processing will be provided during the course, as e.g. on Vista Seismic Processing, Kingdom Suite Seismic Interpretation, mbsystem ,multibeam processing, CARIS multibeam and sidescan processing. The results shall be provided in a journal article form and for a final presentation and discussion round.

Core methods are:
Multichannel seismic, multibeam bathymetry, side scan sonar, sediment echosounding, sound velocity profiling. Other methods as e.g. marine magnetics, heat flow, CTD, geotechnics, video may be added depending on the suggested research projects.

Costs:
Transport costs depend on port call, typically less than 100 €
Food and accomodation on the vessel is free

It is desirable to bring some basic knowledge about physical and geophysical methods.

Participation in master courses with particular marine geophysical focus (e.g. Advanced Geophysical Exploration, Seismic/Acoustic Imaging, Geophysics of the Ocean Crust, Gas Hydrates, Angewandte Geophysik Methoden/Projekte) will be considered for selection of participants
