Multi-frequency, three-dimensional, four-component ocean bottom seismometer dataset acquired from an active fluid flow structure: Scanner Pockmark, North Sea.

A three-dimensional wide-angle active source seismic dataset was acquired during RRS James Cook cruise JC152 (August - September 2017), around the Scanner Pockmark Complex in the North Sea. Data were recorded on 25 four-component ocean bottom seismometers, recording at a sampling rate of 4 kHz. Four different seismic sources were used:

1) a 700 ci (100, 200 and 400 ci) Bolt airgun array towed at 10-12 m below sea surface and fired at 10 s intervals;

2) a 420 ci (2 x 105/105 ci) GI airgun array, towed at 2 m depth below sea surface and fired at 8 s intervals;

3) a Squid sparker (1750 or 2000 J), towed at the sea surface and triggered at 2 s intervals; and,

4) a Duraspark sparker (2000 J), towed at the sea surface and triggered at 2 s intervals.

This dataset complements Bayrakci et al. (2021; https://doi.org/10.1594/PANGAEA.932200) and updates instrument and shot corrections to fit a single, unique set of instrument positions, generated using a grid search algorithm.

Data are provided in standard SEG-Y format. The shot line geometry corrections were performed following the method described in the accompanying document CHIMNEY_OBS_corrections_summary.pdf. All location information is also present in the positioning directory. The data were acquired as part of the 'Characterization of major overburden leakage pathways above sub-seafloor CO2 storage reservoirs in the North Sea' (CHIMNEY) project, funded by the Natural Environment Research Council (NERC) under grant reference NE/N016130/1.
