Notes on Vent Field Description:
"ROV dives in 2016, first on NOAA ship Okeanus Explorer cruise EX1605-Leg 1 (http://oceanexplorer.noaa.gov/okeanos/explorations/ex1605/) and subsequently on R.V. Falkor (Butterfield & Shipboard Scientific Party, 2017) discovered the Hafa Adai site, with multiple high (280°–339°C) and low (∼20°C) temperature vent discharge spanning ∼300 m and centered at 16.957°N, 144.868°E, in the middle of the Sentry plume anomalies (Figure 4b)." from Baker et al., 2017
