New Zealand's location – with an Exclusive Economic Zone of 4 million km2 and an Extended Continental Shelf of 1.7 million km2 - makes it a nautical nation with a vast sea area available for hydrographic studies. Research in Hydrographic Surveying at the School covers the fields acoustic measurement, high-resolution bathymetric mapping of the seabed, inland rivers and lakes and legacy hydrographic data.
