Marine seismic data acquisition off Oleron island
YEAR(S): 2017 - 2018
LOCATION: CHARENTE-MARITIME (FRANCE)
- Acquisition of single-channel seismic reflection profiles
The BRGM wanted to carry out a very high resolution single-channel seismic reflection acquisition campaign off the island of Oléron.
The acquisition was achieved by mobilizing single-channel seismic reflection equipment consisting of a 30-strand Sparker SIG, a 50-J source with a firing rate of 500 ms, a SIG 16.8.5 flute and DelphSeismic. The positioning is done by GPS onboard and correction of the cable length spun.
A linear of 765 km of profiles was collected in 3 measurement campaigns (10/2017, 11/2017 and 04/2018), calibrated on niches of very good weather-oceanographic conditions.
