Deep Fault Drilling Project (DFDP) Seismic Data
Database
An active source seismic experiment was conducted around the Deep Fault Drilling Project (DFDP)-2B scientific borehole to image the Alpine Fault and provide velocity information about the overburden and metamorphic basement of the Whataroa Valley. Two high-fold seismic reflection lines were collected, which are available on the OpARA repository.
Overview
The 2016 survey used the Aries RAM system and a Vibroseis truck from the University of Calgary.
The parameters of the survey are :
- 10m geophone spacing (Line 2000 Stn 1101 – 1412 : Line 4000 stn 3251 – 3368)
- 10m Vibroseis source point interval
- Vibe sweep 16 second with 4 second Listen Period
- 4 x Sweep 10 – 150 Hz with 100 ms cosine taper
Line 2000 comprises a continuous line from SE to NW, passing west of the wellhead and continuing across the Alpine Fault surface trace to the NW. Line 4000 comprises a line through the well pad, parallel to the deviated well. There is a gap across the Whataroa river, then the line continues to the north.
The data is available on OpARA (Open Access Repository and Archive), the repository for digital research data of the TU Dresden (TUD) and the TU Bergakademie Freiberg (TUBAF).
You can find more information about the data in the Whataroa 2016 seismic experiment acquisition report(external link).
