    <r:Abstract>
      <r:Content xml:lang="sv">År 2011 gjordes två nya reflexionsseismiska undersökningar över västra delen av Siljansringen, Mora och Orsa profilerna. Siljansringen är en struktur som uppkom för ca 377 miljoner sedan genom ett meteoritnedslag. Orsa profilen (detta dataset) är ca 12 km lång och visar de geologiska strukturerna till ca 3 km djup. Geologin består av flera hundra meter med siluriska klastiska sedimentära bergarter och ordoviciska karbonatbergarter som vilar på paleoproterozoiskt kristallint urberg. 

Datasetet innehåller rådata för Orsa-profilen, efter avkodning.

En mer detaljerad beskrivning av datasetet som inkluderar alla viktiga parametrar är tillgängligt på den engelska katalogsidan.

Data är tillgängliga efter förfrågan med anledning av filstorlek.</r:Content>
      <r:Content xml:lang="en">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 Orsa profile. The profile has length of c. 12 km and the processed data image the geological section to about 3 km depth (Silurian siliciclastic and Ordovician carbonate rocks to serveral hundred metres depth, below disturbed Paleoproterozoic crystalline basement). During the survey, 542 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 raw data of the Orsa 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:

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: 12 km
Source points: 542
Dates acquired: 10/6–15/6: 2011

File format: SEGD rev 2; Field acquisition notes scanned to PDF

Digital shot records, one file per shot, according to SEG technical standard SEG-D revision 2.1 (SEG-D_r2.1, 2006); https://seg.org/Publications/SEG-Technical-Standards
