| Title
| - Processed seismic data of Cruise SO122 1997
- Prozessierte seismische Daten der Fahrt SO122 1997
|
| Description
| - Die SONNE-Fahrt SO122 fand unter Federführung der BGR vom 3. August bis zum 6. September 1997 statt. BGR, GEOMAR, das National Institute of Oceanography (NIO, Karachi) und das Hydrocarbon Development Institute of Pakistan (HDIP) wollten in einem gemeinsamen Projekt den Makran-Akkretionskeil reflexionsseismisch, gravimetrisch und magnetisch untersuchen. Intensive Fischerei in den Gebieten vor der pakistanischen Küste zwang zur Verlagerung des Arbeitsgebietes nach Süden unter folgender Zielsetzung: Untersuchung der Krustenstruktur und der Verbreitung von Meeresboden simulierenden Reflektoren (BSR) an der Basis von Gashydraten im Makran-Akkretionskeil; Untersuchung der Strukturmerkmale des Murray-Rücken-Systems zur Rekonstruktion der geodynamischen Geschichte des östlichen indischen Plattenrandes; Bestimmung der Krustenstruktur unter dem Indus-Fächer sowie der Bestimmung der Sedimentationsgeschichte im Indus-Fächer als Hinweis zur geologisch-tektonischen Geschichte des Himalayas.
- The Sonne Cruise SO122 was carried out by the Federal Institute for Geosciences and Natural Resources (BGR, Hannover) from 3rd August to 9th September 1997, in cooperation with GEOMAR (Kiel), the National Institute of Oceanography (NIO, Karachi) and the Hydrocarbon Development Institute of Pakistan (HDIP). During the joint project with R/V SONNE the Makran accretionary wedge off Pakistan should have been investigated in detail with multi-channel reflection seismics, magnetics and gravimetry. Intense fishery offshore Pakistan forced a change of the area of investigation to the south with the following objectives: investigation of the crustal structure and occurrence of the bottom simulating reflector (BSR) in the Makran accretionary wedge; investigation of the structure of the Murray Ridge System in order to reconstruct the geodynamic evolution of the eastern Indian Plate margin; determination of the origin of the crust underlying the Indus Fan and reconnaissance of the sedimentary history of the Indus Fan in order to reveal the uplift and erosion history of the Himalayas.

| - During the period from 3rd August to 6th September 1997 BGR acquired seismic lines off Pakistan. The lines SO122-03, SO122-04, SO122-04A, SO122-08, SO122-09, SO122-10, SO122-11, SO122-12, SO122-13, SO122-13A, SO122-14, SO122-15, SO122-16, SO122-17, SO122-18, SO122-19, SO122-19A, SO122-19B, SO122-21, SO122-22, SO122-23, SO122-24, SO122-25, SO122-26, SO122-27 are processed (migrated) data.
