Seawater dissolved inorganic carbon and total alkalinity for UK Shelf Sea Biogeochemistry collected by Marine Scotland Science.

This dataset contains 63 measurements of seawater dissolved inorganic carbon (DIC) and total alkalinity (TA) from the northwest European continental shelf sea to the north of Scotland (55-67 N, 10 W-13 E). The samples were collected from April 2014 to January 2015 by Marine Scotland Science (MSS) cruises 0514S, 0614S, 0714S, 1314S, 1714S and 0115S, as part of the UK Shelf Sea Biogeochemistry research programme (UK-SSB). The purpose was to constrain the surface layer DIC and TA concentrations, in order to calculate air-sea CO₂ fluxes. All measurements were carried out in November 2015 using VINDTA 3C instruments (#024 and #038, Marianda, Germany) at the University of Southampton (UK). Bad results resulting from technical issues during analysis have been removed from these results, so there are no recognised issues. The data were collected as part of the SSB research programme in the CaNDyFloSS: Carbon and Nutrient Dynamics and Fluxes over Shelf Systems (NE/K00185X/1) research programme component. SSB was co-funded by the Natural Environment Research Council (NERC) and the Department for Environment, Food and Rural Affairs (Defra). The programme took a holistic approach to the cycling of nutrients and carbon and the controls on primary and secondary production in UK and European shelf seas, to increase understanding of these processes and their role in wider biogeochemical cycles. The British Oceanographic Data Centre (BODC) created the metadata entry and is responsible for holding master copies of the data.

本数据集包含63组海水溶解无机碳（dissolved inorganic carbon, DIC）和总碱度（total alkalinity, TA）的测量数据，采样区域为苏格兰北部的西北欧大陆架海域（纬度55-67°N，经度10°W-13°E）。样本由苏格兰海洋科学局（Marine Scotland Science, MSS）于2014年4月至2015年1月通过0514S、0614S、0714S、1314S、1714S及0115S航次采集，作为英国大陆架海域生物地球化学研究计划（UK Shelf Sea Biogeochemistry research programme, UK-SSB）的一部分。其目的是确定表层海水的DIC和TA浓度，以计算海气CO₂通量。所有测量于2015年11月在英国南安普顿大学完成，使用的是德国Marianda公司生产的VINDTA 3C仪器（编号#024和#038）。分析过程中因技术问题产生的无效数据已被剔除，因此本数据集无已知问题。这些数据属于UK-SSB研究计划下属的CaNDyFloSS子项目（全称Carbon and Nutrient Dynamics and Fluxes over Shelf Systems，项目编号NE/K00185X/1）。UK-SSB由自然环境研究委员会（Natural Environment Research Council, NERC）和环境、食品与农村事务部（Department for Environment, Food and Rural Affairs, Defra）联合资助，该计划采用整体方法研究英国及欧洲大陆架海域的营养盐与碳循环，以及初级和次级生产的调控机制，旨在增进对这些过程及其在更广泛生物地球化学循环中作用的理解。英国海洋学数据中心（British Oceanographic Data Centre, BODC）创建了元数据条目，并负责保存该数据集的主副本。
