Ambitle Island
- Name: Ambitle Island, off Papua New Guinea
- Characteristics: Shallow hydrothermal vents that spew more than a kilogram of arsenic a day into the surrounding waters.
- Importance: Studies of how local microbes cycle arsenic through the ecosystem could shed light on how other microbes process arsenic in places such as Bangladesh, the site of massive groundwater poisonings.
