Measuring mussel float motion by radar. The radar is equivalent to 30 police radars monitoring different points on the water surface.

Currently over 100 000 km2 of seafloor around New Zealand are permitted for hydrocarbon exploration. NIWA has been undertaking seafloor surveys for new gas pipelines to shore, and site surveys for oil-rig drilling operations. In recent months we have undertaken multibeam and high-resolution seismic surveys of the Kupe and Pohokura production sites and possible pipeline routes, and a site survey of the Tui development area for engineering evaluations.
