Seabed mapping

NZ has a range of different types of coasts, and so very different coastal erosion and sediment systems.

Hull-mounted on the RV Tangaroa, the EM302 multibeam echosounder maps the seafloor using a fan of 288 acoustic beams, producing up to 864 soundings per ping in dual swath mode, providing 100% coverage of the seabed.

Hydrocarbons, although requiring increasingly responsible use, are still an essential part of our modern economy. NIWA has provided survey and consultancy services related to the exploration of offshore mineral resources for thirty years.
