Ocean Drilling

The key to understanding the geological history, resource potential and subsurface environment of the New Zealand continent lies in the rocks beneath the sea.

Joides Resolution

Ocean drilling allows scientists to sample rocks or install instruments within the Earth's crust. Drilling has played an important role in understanding the Earth's history and structure recorded sediments and rocks beneath the seafloor. It is the only way to “ground truth” geophysical interpretations of the subsurface and is useful for monitoring sub-seafloor environments.

GNS Science coordinates New Zealand’s participation in the Integrated Ocean Drilling Programme (IODP).

Scientists at GNS Science are directly involved in several active IODP proposals around New Zealand, the wider SW Pacific and Tasman regions, and the Ross Sea, Antarctica. In addition we are involved in numerous ancilliary geological and geophysical surveys and studies supporting the scientific questions and hypotheses being addressed in these proposals.
