Colville Ridge

GNS scientists are embarking on a 21 day voyage to the northern Colville Ridge NE of New Zealand to undertake the first ever systematic marine survey of the seafloor in this area.

The survey will collect a suite of geophysical parameters such as gravity, magnetic and bathymetry data as well as rock samples collected by dredge.

This voyage builds on two previous surveys of the southern and mid Colville Ridge undertaken in 2013 and 2015 respectively, providing the first comprehensive seafloor map and geophysical data sets. Combined, these new data sets will provide fundamental information to scientists studying plate tectonics, mineralization and understanding the geological setting NE of New Zealand.
