Identifying Zinc Inputs to Heard and McDonald Islands Region using Zinc Concentrations and Isotopic Compositions

Research indicates that hydrothermal activity near Heard and McDonald Islands, an active volcanic region in the Southern Ocean, may be contributing zinc (Zn) to surrounding waters. This study used Zn concentrations and isotopic compositions to explore potential Zn sources, suggesting a possible hydrothermal influence near McDonald Island and specific stations around Heard Island. The findings hint at enhanced biological productivity due to trace element inputs from volcanic activity. To strengthen conclusions, additional data such as Zn excess and mantle helium concentrations are recommended.
