OS2020 R/V Tangaroa
-
UNCLOS Eastern Region survey undertaken by the R/V Tangaroa
-
Multibeam data from New Zealands International Polar Year - Census of Antarctic Marine Life (IPY-CAML) project which incorporated a 55 day R/V Tangaroa voyage to the Ross Sea region in February-March 2008. Multibeam data was collected using a Kongsberg EM300 echo sounder.
-
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
-
Multichannel seismic data from the "Bay of Plenty Neotectonics Whakatane Graben Extension" voyage (TAN9914) of the R/V Tangaroa. The voyage was undertaken as part of the "Extensional Back-arc Processes" project of the "Active Seabed Processes" FRST programme. The objectives of the programme are to determine the contemporaneous processes of extensional faulting, subsidence andc sedimentation in the Wanganui Bight and Bay of Plenty, to compare the mechanisims of extension, potential seismicity of offshore faluts, and the influence of sealevel cycles on sediment-tectonic interactions at opposite ends of the back-arc region of the Hikurangi subduction zone.

MARGINS R/V Tangaroa
-
Multibeam data from the "Wanganui Neotectonics - Back-arc Extension" voyage (TAN0105) of the R/V Tangaroa. Multibeam data was acquired on the Narrows Basin of Cook Strait as part of this voyage. The voyage was undertaken as part of the "Extensional Back-arc Processes" project of the "Active Seabed Processes" FRST programme. The objectives of the programme are to determine the contemporaneous processes of extensional faulting, subsidence and sedimentation in the Wanganui Bight and Bay of Plenty, to compare the mechanisims of extension, potential seismicity of offshore faluts, and the influence of sealevel cycles on sediment-tectonic interactions at opposite ends of the back-arc region of the Hikurangi subduction zone.
