Description

In 2008, a 22 km long high resolution reflection seismic profile was acquired over the Burträsk fault in Northern Sweden. The Burträsk fault formed at the end of the last glacial, triggered by the rapid melting of the Scandinavian ice sheet and the following crustal rebound. The aim of the survey was to image the structure of the fault with depth. The profile followed existing roads resulting in a very crooked acquisition geometry. A list of the key acquisition parameters is given below.
The dataset was first processed and published in 2011. In 2018, the dataset was reprocessed using an additional cross-dip correction step to improve the imaging of reflection with a dip component in the cross-profile direction. The following data files are available for downloading:
1) raw shot gathers (decoded and quality controlled, with geometry information in the headers)
2) original stacked section from Juhlin and Lund (2011)
3) cross-dip corrected stacked section from Beckel and Juhlin (2019)
4) cross-dip corrected migrated section from Beckel and Juhlin (2019)
