Seawater dissolved inorganic carbon and total alkalinity for UK Shelf Sea Biogeochemistry cruise DY033 (version 2).

This dataset contains 201 measurements (188 from CTD rosette, 13 from underway) of seawater dissolved inorganic carbon (DIC) and total alkalinity (TA) from the Celtic Sea (50 N, 8 W). The samples were collected during RRS Discovery cruise DY033 in July-Aug 2015, as part of the UK Shelf Sea Biogeochemistry research programme (UK-SSB), in order to constrain the interior DIC and TA inventories. Measurements were carried out using VINDTA 3C instruments (#024 and #038, Marianda, Germany) at the University of Southampton (UK). Updated from v1 (doi:10.5285/50fbe4de-f777-1cde-e053-6c86abc0a855) on 17-07-2017 to include an additional 44 measurements (44 from CTD rosette, 2 from underway). 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201组海水溶解无机碳（dissolved inorganic carbon，DIC）与总碱度（total alkalinity，TA）实测数据，其中188组来自CTD采水器（CTD rosette），13组来自走航观测（underway），采样区域为凯尔特海（Celtic Sea，北纬50°，西经8°）。样品采集于2015年7-8月的RRS Discovery科考航次DY033，作为英国陆架海生物地球化学研究计划（UK Shelf Sea Biogeochemistry research programme，UK-SSB）的一部分，旨在限定海区内部DIC与TA的储量。实测工作由英国南安普顿大学的VINDTA 3C型仪器（编号#024与#038，德国Marianda公司生产）完成。本数据集于2017年7月17日从v1版本（DOI:10.5285/50fbe4de-f777-1cde-e053-6c86abc0a855）更新，新增44组数据（其中44组来自CTD采水器，2组来自走航观测）。分析过程中因技术问题产生的不合格结果已被移除，目前无已知数据质量问题。本数据作为SSB研究计划中CaNDyFloSS：陆架系统碳与营养盐动力学及通量（Carbon and Nutrient Dynamics and Fluxes over Shelf Systems，项目编号NE/K00185X/1）的组成部分采集完成。SSB计划由自然环境研究委员会（Natural Environment Research Council，NERC）与环境、食品与农村事务部（Department for Environment, Food and Rural Affairs，Defra）联合资助。该计划采用整体系统研究思路，探究英国及欧洲陆架海的营养盐与碳循环过程，以及初级、次级生产的调控机制，以加深对上述过程及其在更大尺度生物地球化学循环中作用的理解。英国海洋数据中心（British Oceanographic Data Centre，BODC）负责创建本数据集的元数据条目，并保管数据的主副本。
