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 are published here: 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. Key acquisition parameters are: Number of channels: 320 (160-160) Near offset: 0m Geophone spacing: 10 m Geophone type: 28 Hz single Source spacing: 20 m Source type: VIBSIST 3000 Hit interval between hammer blows: 100-200 ms Sweeps per source point: 3-4 Nominal fold: 80 Recording instrument: SERCEL 428UL Sample rate: 1 ms Field low cut: Out Field high cut: 400 Hz Record length: 30 s Profile length: 10 km Source poi
