Instead it had jets of sulfur shooting out from many holes in the sediment-covered seafloor."; 2012 cruise blog, accessed 24 April 2015, "Niua North, with its profuse venting of magmatic gases and sulfur volcanism, contrasts dramatically with the (presumably) more deeply rooted Niua South magma source with its extensive black smoker vent fields."; video of sulfur plume, dive Q330, accessed 24 April 2015,; Merle et al. (2008): tow NELSC, t08c14; Baker et al. 2019: site 32 in Table 2;
