Since the discovery of the deep subseafloor biosphere in the mid-1990s, scientists have studied the conditions under which organisms thrive in this isolated and generally food-deprived environment and wondered which conditions set a limit to the existence of life. In 2016, a group of international scientists set out to sea on board the Japanese scientific drillship, Chikyu, to study the temperature limit of the deep subseafloor biosphere. Sediment samples were collected from a drill hole that cut through the geological subduction zone of the Nankai Trough off Japan.
