Discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity, nutrients and dissolved oxygen during the R/V John Strickland Properties Survey cruises 2015-07, 2015-11, 2016-07 and 2017-01 (EXPOCODEs 18S720150722, 18S720151109, 18S720160726 and 18S720170124) in the Juan de Fuca Strait of the North American Pacific coast from 2015-07-22 to 2017-01-24 (NCEI Accession 0232540)

This NCEI accession consists of discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity, nutrients and dissolved oxygen during the R/V John Strickland Properties Survey cruises 2015-07, 2015-11, 2016-07 and 2017-01 (EXPOCODEs 18S720150722, 18S720151109, 18S720160726 and 18S720170124) in the Juan de Fuca Strait of the North American Pacific coast from 2015-07-22 to 2017-01-24. There were 58 DIC/TA pairs collected from Juan de Fuca Strait near to the sewage outfalls off the coast of Victoria BC, with 27% replication rate and pooled standard deviations of 0.66 and 1.28 umol/kg and respectively. Discrete total alkalinity (TA); dissolved inorganic carbon (DIC);and nutrient samples were taken from rosette casts with 10L Niskin bottles and analyzed at the Institute of Ocean Sciences. CTD profiles were recorded with each rosette cast. Data interpreted and published in Krogh et al. 2018 – Risks of hypoxia and acidification in the high energy coastal environment near Victoria Canadas untreated municipal sewage outfalls.

本数据集为美国国家环境信息中心（National Centers for Environmental Information, NCEI）收录的实测剖面数据集，采集于2015年7月、2015年11月、2016年7月及2017年1月的“约翰·斯特里克兰德号”（R/V John Strickland）Properties Survey考察航次，覆盖北美太平洋沿岸的胡安·德富卡海峡（Juan de Fuca Strait），时间跨度为2015年7月22日至2017年1月24日；测量参数涵盖溶解无机碳（dissolved inorganic carbon, DIC）、总碱度（total alkalinity, TA）、水温、盐度、营养盐与溶解氧，各航次对应的EXPOCODE编号分别为18S720150722、18S720151109、18S720160726及18S720170124。本次研究在不列颠哥伦比亚省维多利亚市沿岸排污口附近的胡安·德富卡海峡海域共采集到58组DIC/TA配对样本，重复采样率为27%，合并标准差分别为0.66 μmol/kg与1.28 μmol/kg。总碱度、溶解无机碳与营养盐样本均通过搭载10升尼斯金（Niskin）采水器的多框采水装置采集，并于加拿大海洋科学研究所（Institute of Ocean Sciences）完成实验室分析。每次多框采水作业均同步记录CTD剖面数据。本数据集的相关解读与研究成果发表于Krogh等人2018年的学术论文：《加拿大维多利亚市未处理市政排污口附近高能海岸环境的缺氧与酸化风险》（原英文标题：Risks of hypoxia and acidification in the high energy coastal environment near Victoria Canada's untreated municipal sewage outfalls）。
