Metadata: Datasets from sediment cores collected from the Semenov Hydrothermal Field during the RRS James Cook cruises JC224 (2022) and JC254 (2023)
Abstract:
This dataset comprises a variety of sediment core data from the Semenov Hydrothermal Field region of the Mid-Atlantic Ridge, collected during RRS James Cook cruises JC224 (March - April 2022) and JC254 (October - November 2023). A total of 29 gravity cores, 9 mega-cores, and 25 push cores were successfully recovered. Analysis of the sediment core samples was conducted at the British Ocean Sediment Core Research Facility (BOSCORF), where the cores are held for long term storage, and included: imaging, spectrometry, geophysical and geochemical measurements of sediment and porewaters, radiocarbon dating, and stable isotope analysis. The main coring equipment used during both cruises was a gravity corer to collect sediment cores of up to 3 m in length. For JC224, a mega-core, with a USBL transponder attached to the frame, was used to obtain undisturbed cores from the upper 40 cm of the sediment surface. For JC254, push cores were also collected during several Remotely Operated Vehicle (ROV) dives using the Isis vehicle. The key objectives of the sediment coring were: (1) to reconstruct the history of the hydrothermal activity by dating plume fallout layers in the sedimentary record, and (2) to assess the role of the sediment cover in the preservation of seafloor massive sulphide (SMS) deposits in an ultra-slow spreading scenario. The data were collected as part of a PhD project funded under the Natural Environment Research Council (NERC) project Ultramafic-hosted mineral Resource Assessment (ULTRA) grant, NE/S004068/1. This collection consists only of the data collected under the PhD project and not all data associated with the ULTRA project.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | 48 gravity cores, 9 mega-cores and 25 push cores were successfully collected from the Semenov Hydrothermal Field area of the Mid-Atlantic Ridge during the ULTRA cruises JC224 and JC254. Samples were imaged and geochemically analysed using in-house software at the British Ocean Sediment Core Research Facility (BOSCORF), details of which can be found here: https://boscorf.org/research-facility. The data were then provided to the British Oceanographic Data Centre (BODC) for long-term archive in the BODC Published Data Library. BODC supply full information about data collection, data processing and data quality with all data requests to enable users to assess data suitability themselves.Instrument(s) used to collect data: cameras; unconsolidated sediment corers; autoanalysers; titrators; inductively-coupled plasma mass spectrometers; mass spectrometers; gamma-ray spectrometers; X-ray fluorescence analysers; magnetic susceptibility systems; Volume measures; laboratory optical rangefinders. |
