The DAN-IODP-SEIS is aimed at investigating the geological development of Kattegat during the last 130.000 years. This will be based on acoustic (seismic) methods and geological interpretation of cores from previously drilled shallow wells and the IODP wells drilled in 2013. A large number of reflection seismic data (conventional and sleevegun) in addition to high resolution sparker seismic data, have over time been acquired in parts of Kattegat by various companies and GEUS. Based on the location and preliminary interpretation of these data, it has been possible to acquire new acoustic data during June/July 2013 and September 2013 on two cruises in cooperation with Sweden’s Geological Survey and Hamburg University. On the cruises, multichannel airgun seismic, sparker seismic and innomar data were acquired and these data both fill out areas with data gap and is acquired in new areas. The data will be integrated with already existing archive data.
The data is to be processed and interpreted using state of the art interpretation software (Petrel). Seismic examples are shown to illustrate aspects of the geological development of the Kattegat.

This PhD project is funded by Geocenter Denmark and is a collaboration project between IGN, GEUS and IGG. Further information regarding the cruise that took place in June-July will be available in issue no. 3 2013 of Geoviden.
