“…One important aspect of the spatial variability in LGM radiocarbon ventilation ages that has yet to be completely resolved, is the observation of extreme radiocarbon depletions (i.e., the equivalent of more than 4,000–10,000 14 C yrs offset from the contemporary atmosphere). These offsets have been observed in foraminifera from a handful of locations, primarily at intermediate water depths, off Galapagos and in the southern Pacific in particular (Bova et al., 2018; Ronge et al., 2016; Stott et al., 2009, 2019). The same challenge arises in accounting for “extreme” marine radiocarbon depletion anomalies that have been observed at a few locations subsequent to the LGM, across the last deglaciation (in both benthic and planktonic foraminifera), again primarily at intermediate water depths in the low‐latitude eastern Pacific (Lindsay et al., 2015; Marchitto et al., 2007; Rafter et al., 2018, 2019), but also the South Pacific (Ronge et al., 2016, 2019), and Arabian Sea (Bryan et al., 2010).…”
