  • OS2020 R/V Tangaroa

  • Multichannel seismics data from the "Southern Kermadec Volcanoes: Geology and Benthic Biology" voyage by the R/V Tangaroa. Multichannel seismic reflection profiling was run across the Macauley caldera structure to image both typical sectors of the caldera, and possible breached wall on the northwestern rim. The orientation of the MCS lines was determined from the EM300 multibeam data. Survey Leader: Ian Wright Organisations: NIWA Seismic Instrument: 210 CU.IN. GI AIRGUN, 48-CHANNELS Navigation Instrument: Furuno GP500 DGPS Ports: Auckland to Auckland

  • Multibeam data from the "Southern Kermadec Volcanoes: Geology and Benthic Biology" voyage by the R/V Tangaroa. The main voyage objective was the EM300 multibeam mapping of eight southern Kermadec volcanoe along with the arc from between 34°50'S - 30°10'S along with transit legs over two other volcanoes.. Rock/epibenthic dredging and seafloor photography was carried out on the eight prinipal volcanoes. Survey Leader: Ian Wright Organisations: NIWA Bathymetric Instrument: Simrad EM300 multibeam Navigation Instrument: Furuno GP500 DGPS Ports: Auckland to Auckland

  • 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.
