Bottle-calibrated dissolved oxygen profiles from yearly turn-around cruises for the Ocean Observations Initiative (OOI) Irminger Sea Array 2014 – 2022

<p dir=\"ltr\">The Ocean Observatories Initiative (OOI) is a long-term NSF-funded program that deploys autonomous sensors on both moored and mobile platforms at multiple locations, including the Global Irminger Sea Array (60.46°N, 38.44°W) (Trowbridge et al., 2019). The OOI program conducts yearly turn-around cruises to the Irminger Sea Array to recover and redeploy moorings and gliders deployed year-round at this site. During these cruises the OOI program routinely conducts Conductivity Temperature Depth (CTD) casts and collects water samples from Niskin bottles on the CTD rosette for discrete sample analysis. These turn-around cruise data are critical for validation and calibration of the data from sensors deployed year-round and also provide a valuable dataset in and of themselves (Palevsky et al., 2023).</p> <p dir=\"ltr\">The complete collection of shipboard data and cruise documentation from these cruises is available from an OOI-managed document storage system called Alfresco (see related publications, cruise data), following the path: OOI &gt; Global Irminger Sea Array&nbsp; &gt; Cruise Data &gt; {Cruise ID}. This dataset uses CTD data collected by the OOI program during the first 9 turn-around cruises of the Irminger Sea Array, alongside supplementary samples collected for this project during the AR30-03 and AR35-05 cruises (see related dataset Palevsky et al., 2023) to produce calibrated, quality-controlled oxygen depth profiles.</p>海洋观测倡议（Ocean Observatories Initiative, OOI）是由美国国家科学基金会（National Science Foundation, NSF）资助的长期观测项目，该项目在多站点的锚定与移动平台上部署自主传感器，其中包括全球伊尔明格海阵列（60.46°N, 38.44°W）（Trowbridge等，2019）。OOI项目每年都会开展针对伊尔明格海阵列的往返巡航任务，以回收并重新部署该站点全年布设的锚定设备与水下滑翔机。在此类巡航任务中，OOI项目常规开展电导率-温度-深度剖面仪（Conductivity Temperature Depth, CTD）走航观测，并通过CTD采水架上的尼斯金采水器采集水样用于离散样本分析。这类往返巡航数据既是全年部署传感器观测数据的验证与校准的关键依据，其本身也是极具科学价值的独立数据集（Palevsky等，2023）。 上述所有巡航任务的船载数据与巡航文档，均可通过OOI管理的Alfresco文档存储系统获取（详见相关出版物、巡航数据），访问路径为：OOI > 全球伊尔明格海阵列 > 巡航数据 > {航次编号}。本数据集整合了OOI项目在伊尔明格海阵列前9次往返巡航任务中采集的CTD数据，以及AR30-03和AR35-05航次中为本项目采集的补充样本（详见相关数据集Palevsky等，2023），最终生成经过校准与质量控制的溶解氧深度剖面。
