The Pioneer Array provides important new perspectives on shelf-break exchange, and observations from the array clearly show that onshore intrusions of warm core ring water masses are penetrating farther onshore than previously noted in historical data or the scientific literature. This is consistent with recent studies described earlier that indicate larger-amplitude Gulf Stream meanders and more frequent warm core rings since the year 2000. However, because the Pioneer Array has only been collecting observations since late 2013, it is difficult to quantify how unusual the recent ring intrusion events have been since 2013 using Pioneer Array observations alone.
