| Objectives | The British Geological Survey Project 06/02 was a marine geophysical survey (seismic reflection, gravitational field, magnetic field, multibeam bathymetry) covering areas from Rockall, Hatton Bank, the banks south west of the Faroe Islands and the Faroe Bank Channel. The survey was designed to address several geological objectives including:
1. Rockall to Hatton Bank: Multibeam only to get full picture from sea-bed to depth (line is coincident with existing BGS seismic collected in 2000 which shows a variety of interesting features). 2. Small area on Hatton Bank: Lines across basalt window to define size and shape of window and orientation of fold axes in Mesozoic. 3. NW edge of Hatton Bank: Lines across SEA7 sites where video of coral obtained. Lines to investigate if there is relationship between coral growth and geological structure. 4. NW edge of Hatton Bank: Lines anticipated to image geological structures some of which might be compressional in origin. Lines cross sea-bed ridges imaged by Spanish 2005 multibeam survey. Origin of ridges unknown (yet). 5. Various banks south west of Faroe Islands: Lines designed to investigate the structure of major banks and Wyville-Thomson and Ymir ridges. One line crosses 'Alpin Dome' between Rosemary Bank and Bill Bailey's Bank 6. Faroe Bank Channel: Lines mainly to investigate seismic stratigraphy and sediment patterns in Faroe Bank Channel. Also to look for possible future borehole location(s). 7. St Kilda: Short high resolution lines were run just south of St Kilda to tie in an existing piston core to existing BGS Deep Tow Boomer line. 8. Stanton Bank: High resolution seismic reflection line were run for the MESH project to compliment previously acquired data in 2005 on project BGS 05/05 (CD174). |
