Processed seismic data of Cruise BGR17 2017 (MSM67 SEGMENT)

The MSM67 SEGMENT research cruise was carried out between August 31st and October 4th 2017 aboard the research vessel MARIA S. MERIAN. Survey MSM67 SEGMENT it is intended to study the architecture of the rifted continental margin off East Greenland around the Jan Mayen fracture zone. Key issues to be addressed are margin segmentation and the location of the continent-ocean transition (COT). Both subjects are highly debated. Symmetric segmentation of conjugate margins has significant implications on our general understanding of continental rifting processes, and a margin-parallel COT off East Greenland would indicate an N-S opening in the Norwegian/Greenland Sea. The latter challenging most publications on the early evolution of the North Atlantic. A major open question is also the timing, duration and distribution of magmatism that resulted in the formation of the North Atlantic large igneous province. Previous suggestions of very short (~3 Myr) periods of intense magmatism have been challenged and a much longer duration and/or a post-breakup origin are under discussion. Here, we want to establish the amount of post-breakup magmatism as evident in high-velocity lower crust and test the dependence of magmatism with distance from the proposed hot-spot under Iceland and the influence of major fracture zones on volcanism.

Quality and validity

Lineage: During the period from the 31st of August to the 4th of October 2017 BGR acquired seismic lines east of Svalbard in the Greenland Sea. The lines BGR15-201, BGR15-204, BGR15-205, BGR15-206, BGR15-207, BGR15-208, BGR15-209A, BGR15-210, BGR15-211, BGR15-212, BGR15-213, BGR15-214, BGR15-215, BGR15-215B, BGR15-216 and BGR15-217 consist of stacked data. The lines BGR15-202 and BGR15-203 consist of migrated data.
