Ziel der Reise / Objectives of Cruise:
During cruise M88/1 RV Meteor was used by the Marine Seismic group of BGR (Federal Institute for Geosciences and Natural Resources, Hannover). Main objectives were to initialize and configure all components of a recently purchased 3D marine seismic data acquisition system and subsequently to operate the complete system to acquire a 3D data set in an area of limited extent. The cruise was subdivided into two legs by a call at the port of Aberdeen The first two weeks of the allocated 4 weeks time slot were spent to acquire methodical know-how in configuring and applying 3D multichannel seismic equipment onboard a multi-purpose research vessel. A low traffic area in the British sector of the North Sea with water depth deeper than 40 m was selected for these operations. After transit to the working area off the Scottish coast in the British sector of the North Sea all 3D seismic components were comprehensively tested and individually configured between August 10th and 24th. The tests included deck handling of the outboard systems as well as testing all hardware and software components for precise navigation, system control and data acquisition according to industry standards At the end of this leg part of the scientific crew was exchange. In the period between August 24th and September 9th a first 3D seismic data acquisition was scheduled for a small sized area which is of special geological interest. To make benefit of the acquired data for a currently running mapping project in the German sector of the North Sea this survey was completed in a 60 km? area W of Heligoland. The survey area covers part of the targets for survey operations during the subsequent cruise M 88/2. During the 3D siesmic survey all requirements of precise navigation and standards for maximum folding of 3D seismic data using 900 m long streamers were aimed.
