“…Observations from the OOI can be used to explore myriad Earth system processes (Trowbridge et al, 2019), such as undersea volcanic eruptions (Wilcock et al, 2018), methane hydrates (Philip et al, 2016), earthquakes (Tréhu et al, 2018), coastal hypoxia (Barth et al, 2018), heat budgets (Chen et al, 2018), warm core rings (Gawarkiewicz et al, 2018), global ocean-atmosphere exchange processes (Ogle et al, 2018), and the oceanic biological pump (Palevsky and Nicholson, 2018). Real-time OOI data streams not only provide an effective resource for improving ocean literacy Matsumoto, 2007, 2009) and bring to life many important concepts taught in ocean and Earth science classes ( Table 2), they also represent an opportunity for the oceanographic community to expand the reach of its science into classrooms.…”
