Final stack results and example receiver gathers from South Korea seismic reflection campaign in 2021

Resulting data from the 2021 campaign in the Seoul metropolitan area (South Korea). Around 40 km of high-resolution reflection seismic data were acquired along an E-W profile cross-cutting major crustal scale fault systems. The raw data were obtained with 2 seismic vibrators as source and 421 10 Hz geophones as receivers, with an asymmetric split spread and roll-along geometry. The acquired data has been processed with Globe Claritas software and it is provided in a standard seg-y format.

A full description of the data aquisition is provided in:

However, the methodology is the same as used in the previous study:

In the dataset are present:
- 2 examples of receiver gathers raw: (korea2021_P3_rec1185_raw.segy and korea2021_P3_rec487_raw.segy).
- the same 2 receiver gathers after the applied processing: (korea2021_P3_rec1185_raw_rfst_fils_res_tm.segy and korea2021_P3_rec487_raw_rfst_fils_res_tm.segy).
- stack section acquired with wireless receivers (20 m spacing), unmigrated and migrated:(korea2021_P3_stack.segy and korea2021_P3_migrated.segy).
- stack section acquired with wireless receivers (20 m spacing) with an applied cross dip correction for 10 degrees towards north, unmigrated and migrated: (korea2021_P3_crossdipcorrected_stack.segy and korea2021_P3_crossdipcorrected_migrated.segy).
- unmigrated stack section acquired with landstreamer receivers (2 m spacing): (korea2021_P3_streamer_stack.segy. Show less..
