The chimney structure was also drilled for core samples, which were subsequently analysed alongside synthetic rock samples in various on-shore laboratory experiments. Seismic data were acquired using sources including Bolt and GI airguns, and various sparkers. Data were recorded using multi-channel streamers and by a series of ocean bottom seismometers. The drilled rock samples were analysed at the National Oceanography Centre, Southampton (NOCS) Rock Physics Laboratory, and were compared with synthetic rock samples with aligned fractures. Data were quality controlled and processed by the JC152 Science Party. In conjunction with multi-beam bathymetry data acquired on the same cruise, these data enabled scientists to understand the surface and internal structure and origin of the chimney structure. This facilitated estimation of the permeability of the chimney and its surroundings, and enabled leakage pathways to be determined. The potential for past oil and gas reservoirs and saline aquifers to be used as Carbon Capture and Storage (CCS) reservoirs of atmospheric CO2 were subsequently explored. The safety of storing CO2 in such reservoirs is dependent on fully exploring the risks of any leakage from such chimney structures. CHIMNEY was funded by the Natural Environment Research Council (NERC) under grant reference NE/N016130/1, and involved scientists from the National Oceanography Centre, Southampton and the University of Edinburgh. Investigators worked closely with project partners at GEOMAR, Lawrence Berkley National Laboratory, CGG SA and Applied Acoustics Engineering Technologies Ltd . The project was complementary to the EU-funded Horizon 2020 project: Strategies for Environmental Monitoring of Marine Carbon Capture and Storage (STEMM-CCS).

Data managers quality assure submissions and assemble the metadata necessary for curation. Submissions (as received) are placed in a long-term accession and stored in triplicate across multiple sites. Appropriate data are transferred into a standard internal format with source variable names mapped to controlled vocabularies, documentation assembled, and metadata loaded into BODC databases. Access to these data is through direct request, the BODC website and through partner repositories such as SeaDataNet. Access control is attained by assigning a data policy to each set of data and this policy is used to administer access when data are requested. Discovery metadata is aligned with EU INSPIRE (through MEDIN) and SeaDataNet community standards. Data are converted to open community formats including Ocean Data View ASCII and SeaDataNet NetCDF, with data described using terms from the NERC vocabulary server. BODC submission agreements are documented on the BODC website and customer service is assured with a dedicated requests team that serve data following local regulations including General Data Protection Regulation (GDPR) 2018 and Environmental Information Regulations (EIR) 2004. true This dataset was created by the organisations with the "originator" role in this metadata record following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC), who transferred the data to BODC archive at the Centre for Environmental Data Analysis (CEDA) for long-term storage and data publication.Instrument(s) used to collect data: multi-channel seismic reflection systems; seismic refraction systems; seismometers; hydrophones; airgun array; GI-gun; airgun; Sparker; rock corers.
