Abstract

This dataset comprises images, geochemical composition, isotopic ratio, and X-ray diffraction (XRD) data from samples of Fe-oxyhydroxide (FeOOH) and seafloor massive sulphide (SMS) collected during the RRS James Cook cruise JC224 (March - April 2022) to the 13°30' N ocean core complex (OCC) region of the Mid-Atlantic Ridge, also known as the Semenov Hydrothermal Field. A total of 23 Robotic Underwater Vehicle (RUV) dives were completed with the HyBIS RUV (Murton et al., 2012) in addition to 6 rock dredges setup with a chain bag dredge and a steel bucket dredge behind it. Sampling was focused on the previously described massive sulphide-hosting areas: Semenov-1, -2, -4 and -5 (Escartin et al., 2017), as well as one dedicated dive to a near-circular feature protruding on the southern slope of the OCC - termed the "bulge". Analysis of the 42 FeOOH and SMS samples occurred onshore at the National Oceanography Centre (NOC) and the University of Southampton and the samples are held for long-term storage at NOC Southampton and Cardiff University. A range of analytical methods were used to collect the data, including: inductively-coupled plasma mass spectrometry (ICP-MS), inductively coupled plasma optical emission spectroscopy (ICP-OES), X-ray diffraction (XRD), and reflective light microphotography. The key aims of these analyses were: (1) to improve understanding regarding the formation of Fe-oxyhydroxide samples at SMS systems, and (2) to determine the potential of Fe-oxyhydroxide as an additional resource at SMS systems. 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

A total of 42 Fe-oxyhydroxide (FeOOH) and seafloor massive sulphide (SMS) samples were collected across 23 robotic underwater vehicle (RUV) dives and 6 rock dredges of the 13°30' N ocean core complex (OCC) region of the Mid-Atlantic Ridge during the ULTRA cruise JC224. Samples were imaged onboard and geochemically analysed onshore at the National Oceanography Centre (NOC) and the University of Southampton. 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; sediment grabs; fluorescence microscopes; inductively-coupled plasma mass spectrometers; X-ray diffractometers; rock dredges.

explanation

BODC protocols are based on the Open Archival Information System (OAIS) model enabling BODC to iterate towards compliance with the on-going evolution and development of community requirements including FAIR (Findable,Accessible,Interoperable,Reusable), TRUST (Transparency, Responsibility, User community, Sustainability, Technology) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics). 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.
