Celtic Explorer CE18015
|Ship name (ship code)||Celtic Explorer (45CE)|
|Cruise period||2018-09-17 — 2018-10-07|
|Port of departure||Galway, Ireland|
|Port of return||Galway, Ireland|
|Objectives||SEA-SEIS-D (Strictire, Evolution And Seismic hazard of the Irish offshore: deployment of broadband, ocean-bottom seismometers)
Project to deploy 18 new, broadband, ocean-bottom seismometers across Ireland's offshore, with the instruments provided by the newly established Insitu Marine Laboratory for Geosystems Research Centre. The deployment will start in September-October 2018 and last 12-21 months, depending on whether the instruments will be retrieved in Autumn 2019 or Spring 2020. Surface-wave array tomography will be performed using broadband phase velocity measurements, obtained with ambient-noise and teleseismic cross-correlations and waveform inversions. Waveform tomography of Ireland and NE Atlantic will be performed using 3D waveform sensitivity kernels and the new NAGTEC model of the NE-Atlantic crust. An offshore earthquake catalogue will be obtained. Lithosphere-scale thermal evolution of the basins will be modelled.
In order to enhance the seismic data coverage in the western part of the region, where the north-south extent of the Irish offshore territory narrows, there will be 4 stations in the western part of UK waters, around the Hatton Bank.
