Scripps' marine microbiologist, Doug Bartlett, who organised the expedition, said: "The identification of these gigantic cells in one of the deepest marine environments on the planet opens up a whole new habitat for further study of biodiversity, biotechnological potential and extreme environment adaptation. It is so incredibly deep down there that your bones would literally dissolve in seconds due to the extreme amount of pressure present at those levels. The islands are part of the island arc that is formed on the over-riding plate, the Mariana Plate, on the western side of the trench.
