  • Multibeam data from the "OS2020 Otago multibeam" voyage by the R/V Tangaroa. Survey Leader: John Mitchell Organisations: NIWA Bathymetric Instrument: Kongsberg EM302 multibeam Navigation Instrument: Seastar 9200 DGPS Ports: Wellington to Wellington

  • This is the first of two cruises of the R/V Tangaroa to investigate the oceanography of the Macquarie Ridge system. Macquarie Ridge is situated to the southwest of New Zealand and runs from Fiordland to south of Macquarie Islands. The major objectives were to: 1. deploy moorings to measure the transport of the Antarctic Circumpolar Current and its associated fronts through the two gaps in the Macquarie Ridge; 2. measure ocean tracer properties along the Macquarie Ridge and Campbell Plateau. 3.5kHz soundings were collected for use in planning future coring operations

  • A seabed mapping survey in the Kermadec Volcanic Arc using the SIMRAD EM300 multi-beam echosounder and sub bottom 3.5kHz sounder fitted to the R/V Tangaroa. The voyage comprised multibeam mapping of multiple Seafloor Massive Sulphide deposit target areas within Prospecting Licences PL39-194 (Monowai) of 47,000 km2 area and PL39-205 (Colville) of 13,000 km2 area.
