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>
