Wide-angle deep seismic reflection profile (IBERSEIS Wide-Angle Transect)
The wide-angle seismic reflection data set consists of two transects. Transect A coincides with the trace of the IBERSEIS deep seismic reflection profile and transect B is located farther to the SE. The explosive charge was located in a single 20 cm diameter, 50–60-m deep shothole. Explosive shots w...

| Resumo: | The wide-angle seismic reflection data set consists of two transects. Transect A coincides with the trace of the IBERSEIS deep seismic reflection profile and transect B is located farther to the SE. The explosive charge was located in a single 20 cm diameter, 50–60-m deep shothole. Explosive shots with charge sizes of 1000, 750 and 500 kg, where distributed along the transect, with the largest charges located at the edges of the profile. 650 digital seismic recorders (590 Texans and 60 3-component Refteks) from IRIS (Incorporated Research Institutions for Seismology) instrument pool where used. These instruments where placed along the 300-km transect A at a 400-m station spacing. For transect B, a denser trace spacing was used. To achieve this, shots were fired twice. The stations were firstly placed at 300–400 m spacing along transect B. Once the shots were fired, the stations were moved 150–200 m toward the north along the profile. All shots were then fired a second time, resulting in shot records with a 150–200 m trace spacing. |
