Advanced marine geophysical survey project (6-7 days within 16-30 Sep 2023)

Veranstalter: Thomas Frederichs, Tilmann Schwenk, Volkhard Spieß


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. Seismic/Acoustic Imaging, Applied Geophysics, Geophysical Surveying ...) 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/early autumn.
Preliminary date of the R/V ALKOR cruise 2023:
16.09.2023 - 30.09.2023
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 Arkona or Bornholm Basin as preliminary working areas.

At the begin of cruise, each student will give a short presentation about a marine geophysical method or about the geology/oceanography of the study area.
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 month 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, and sidescan processing. The results shall be provided in a report.

Core methods are:
Multichannel seismic, multibeam bathymetry, side scan sonar, sediment echosounding, water column echosounding, CTD and marine magnetics.

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. Seismic and Acoustic Imaging, Geophysical Survey Strategies, Geophysics of Plates, Mantle ans Margins, ... ) will be considered for selection of participants.
