Nitrogen fixation in the Arctic Ocean (N-ARC) Project Datasets (July - August 2023)
This dataset comprises of data from stainless steel and titanium CTD casts and towfish, results of a nutrient addition incubation experiment, and underway meteorological, hydrographic, and navigational data. The CTD casts and towfish were sampled for biogeochemical properties: nitrate + nitrite, silicate, phosphate, nitrite, d18O, dissolved oxygen, chlorophyll-a, particulate carbon, carbon fixation rates and oxygen isotopes. The CTD casts also comprise of downcast sensor profile data and upcast sensor data at time of bottle firing: temperature, salinity, density, dissolved oxygen, optical backscatter, beam transmittance and attenuation, upward photosynthetically active radiation (PAR), and chlorophyll-a fluorescence. The underway sensor data are sea surface hydrography (temperature and salinity), optical (chlorophyll-a fluorescence, transmission) and meteorological (wind speed and direction, air temperature, air pressure, relative humidity PAR, TIR). The nutrient addition experiments were sampled for Nitrate+nitrite, phosphate, silicate, chlorophyll a, and Fv:Fm after addition of nitrate, phosphate, and/or iron chloride. All of the data were collected during cruise DY167 (GEOTRACES cruise GApr19) in July-August 2023 from Southampton up to the Norwegian and Barents Seas and cover the relatively warm Atlantic Water inflow, fresher water on the Spitzbergen Bank, coastal/glacial outflow around Svalbard, and Arctic water around sea ice. These data were collected to better determine how temperature, light, nutrients, and iron control the distribution and activity of nitrogen fixing organisms in the Arctic Ocean. This dataset was generated by the National Oceanography Centre (NOC), the University of Liverpool (UoL), and the University of Southampton, under Natural Environment Research Council (NERC) Discovery Science grant "Nitrogen fixation in the Arctic Ocean", N-ARC (grant numbers NE/T000570/1 and NE/T001240/1).

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.

This dataset was created by scientists for the NERC project titled Nitrogen fixation in the Arctic Ocean, N-ARC, grant reference numbers: NE/T000570/1 and NE/T001240/1. Downcast CTD sensor data were binned to 1 decibar, whilst the upcast data were averaged 5 seconds around the time of bottle firing. The sensor data were calibrated using discrete samples measurements where possible. Samples measurements were analysed following standard laboratory practices for depending on the property of interest. The underway data were processed in 10-minute means. Following in-house quality control procedures, the data were then submitted to the British Oceanographic Data Centre (BODC) for long-term archive and data publication in the BODC Published Data Library.Instrument(s) used to collect data: fluorometers; radiometers; optical backscatter sensors; atmospheric radiometers; salinity sensor; autoanalysers; inductively-coupled plasma mass spectrometers; isotope ratio mass spectrometers; nutrient analysers; CTD; transmissometers; discrete water samplers; water body temperature sensor; dissolved gas sensors; meteorological packages.
