Arsenic and Antimony in Hydrothermal Plumes from the Eastern Manus Basin, Papua New Guinea

Figure 2

Vertical profiles of temperature and Mn at Stations 18B (a), 18G (b), and 18K (c). “·” denotes the temperature anomaly, and “” denotes the concentration of Mn in the water column samples. The dashed line represents the value of ambient seawater (Mn data (9.30 nM) are the minimum Mn content of the three water column samples) and that of temperature. The seabed depths at Stations 18B, 18G, and 18K are 1759 m, 1606 m, and 1615 m, respectively.
