Rockall Consortium (RCK) Geophysical Survey 2000/1_RCK: Hatton Bank, Hatton-Rockall Basin, Rockall Bank (27/05/2000 to 09/07/2000)

This British Geological Survey (BGS) marine geophysical survey took place in May to July 2000 in the Hatton and Rockall Banks aboard the RV Colonel Templer. This was a regional geophysical survey to gather high resolution seismic, gravity and magnetic data of the area. A total of 5611km of data were collected in a grid of 58 survey tracks using a suite of seismic instruments (airgun, sparker and echo sounder) and also gravity meter and magnetometer. The data was recorded digitally and is archived by BGS. Technical details of the survey are contained in BGS Internal Reports CR/00/42 ( https://nora.nerc.ac.uk/id/eprint/529920/) & CR/01/07.

Statement

Geophysical equipment types used included: Airgun/Sleeve Gun, Echo Sounder, Gravimeter, Magnetometer and Sparker. The survey was undertaken by Rockall Consortium. Airgun: Source: An array of 4 x 40 cu.in. Bolt 600B airguns with waveshape kits and time break solenoids. Any number of guns could be fired simultaneously, but, in all but the shallowest parts of Rockall Bank, all four were used throughout, at a six second firing rate. Two containerised Compair Reavell compressor systems, one owned by BGS and the other hired from Exploration Electronics Ltd., were installed on the vessel. Hydrophone: Two channel Geomechanique summed to give a single channel 30m active length. Sparker: Source: Three different sparkarrays were available: EG&G, nine candle, multi-tip array with 135 tips; Applied Acoustic Engineering ‘Squid’, eight candle, multi-tip array with 120 candles, on loan from the manufacturers; BGS, four candle, multi-tip array with 160 tips. The EG&G array was used for the most part with the others used on occasion for comparison purposes or when the former required candle replacement which could not be completed within a line turn. Hydrophone: Teledyne, 10m, 7 channels with all summed to give a single output. Gravitymeter: The gravitymeter was a ZLS Corporation UltraSys system. Magnetometer: The system used was a Barringer M123 marine proton magnetometer with 1 gamma sensitivity. Echo Sounder: This was an Atlas Deso 20 with a deep water transducer operating at 331Hz. Positioning: The positioning system used was differential GPS utilising two Trimble NT300D GPS receivers with differential corrections received from the Fugro Starfix system. Navigation Processing and Data Logging: Navigation processing and data logging was achieved using a Kelvin Hughes TRAC ‘C’ system. For more information see the Report, https://nora.nerc.ac.uk/id/eprint/529920/.
