Description
Two new reflection seismic profiles over the Paleozoic successions of the western part of the Siljan Ring impact structure were acquired during 2011, the Mora and the Orsa profile. This data set concerns the Mora profile. The profile has length of c. 10 km and the processed data image the geological section to about 3 km depth. During the survey, 391 source points (VIBSIST 3000) were recorded by 320 receiver channels for 30 seconds. From this recording, the following data sets were generated and published: 1) decoded and quality controlled raw data; 2) pre-processed (shot geometry applied) data; 3) stacked data; 4) migrated data; 5) depth converted data and velocity field.
This dataset contains the quality controlled raw data of the Mora profile after decoding the sweep signal the VIBSIST 3000 source.
Processing steps for this data set:
1: Read decoded VIBSIST data
Key acquisition parameters are:
Number of channels: 320 (160-160)
Near offset: 0m
Geophone spacing: 10 m
