From cruise report: "A tow over “Second Volcano”, ~26 km south of the Fonualei dive site (17 47.1’S 173 31.55’W, T12A-01) had very slight (dNTU = 0.005) particle anomalies and a more distinct ORP anomaly (-17 mv), which indicates diffuse low temperature venting occurs near the summit of this volcano."; Baker et al. 2019: site 31 with spreading rate 8 mm/year in Table 1;
