    Fisheries management is increasingly involving a wide range of stakeholders in the decision making process. An implicit assumption in these management structures is that stakeholder representatives present a unified view, and that these views combine to derive optimal management decisions that best satisfy all stakeholders. In this paper, the analytic hierarchy process (AHP) is used to determine the objective preference structure of stakeholder representatives involved in Australian Commonwealth fisheries management. The results indicate that there is generally low coherence within stakeholder groups, suggesting that management decision making is a function more of the set of individuals than the stakeholder groups they represent. The stakeholders represented were from policy and management, science, industry, environment, economics, social science and recreation.

    This dataset contains geoscientific data logged during TELVE cruise (SS02/03) on RV Southern Surveyor 14.3-3.4.2003 in Tonga and Eastern Lau Basin. These data include logged station coordinates and information for dredges, CTD/hydrocasts, echosounder and camera/video operations and geological samples. The TELVE expedition completed 70 dredges, 31 tow-yos, 14 vertical hydrocasts, 9 echo-sounding traces, 2 camera tows, and 1 drogue test. The major scientific objectives of the cruise were a study of the hydrothermal plume activity of the Tofua Arc and adjacent Valu Fa back arc Ridge coupled with sampling of the sea floor with grabs and dredges. Sampling was conducted along the axis of the Valu Fa Ridge, the Tofua Arc between about 21o 30” and 24o 10’S, and one transverse hydrothermal cast from the backarc to arc region at ~ 22o 30’S was done. More specifically, objectives of the voyage were: 1.Perform a continuous along-axis survey for hydrothermal activity along the three segments of the Valu Fa back arc spreading ridge. 2. To the extent possible, conduct a systematic survey for hydrothermal activity along the S. Tonga arc adjacent to the Valu Fa Ridge. 3. Compare (for the first time) the incidence and chemistry of hydrothermal emissions along the adjacent back arc ridge and volcanic arc sections. 4. Coordinate results of back arc ridge survey with RIDGE 2000 investigators slated to perform similar surveys further north on Lau back arc spreading ridges.

    This dataset contains geoscientific data logged during SHAARC cruise (FR04/00) on RV Franklin 5-24.5.2000 in Papua New Guinea and Solomon Islands. These data include logged station coordinates and information for dredges, sediment grabs and cores, CTD/hydrocasts and echosounder operations. The SHAARC research team conducted a multi-disciplinary investigation (volcanology, petrology, geochemistry and economic geology) of submarine volcanic-hydrothermal systems in island arc regions of Papua New Guinea and the Solomon Islands. The team carried out 3 primary scientific activities: (i) Volcanology/Petrology (ii) Hydrothermal Deposits/Geochemistry (iii) Marine Chemistry/Hydrothermal Fluids Although volcanism and associated hydrothermal activity on mid-ocean ridges (MOR) and some back-arc basins have been the focus of many detailed studies over the past decade, only a few submarine arcs and fore-arc regions have received much attention. FR04/00 investigations of the New Ireland-Solomon Islands convergent margin will generate a better understanding of the fundamental geological processes of submarine arc volcanism, including hydrothermal activity and the formation of economic concentrations of ore minerals. These data will be compared to and contrasted with hydrothermal activity occurring at divergent plate boundary volcanism.

  • This record describes multibeam echosounder data collected on RV Investigator voyage IN2025_V05, 'Eruption, destruction and seafloor ecosystem recovery – Tonga 2022 eruption of the century', which departed Hobart on 10 Aug and ended in Brisbane on 01 Oct 2025 (local). The voyage’s first leg transited from Hobart to Nuku’alofa (10–19 Aug 2025), where science participants boarded. A mid-voyage transfer occurred on 05 Sep, and all science personnel disembarked in Nuku’alofa on 23 Sep before the final transit to Brisbane (23 Sep–1 Oct 2025). The Kongsberg EM712 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter data. The EM712 provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 40 to 100 kHz. Data are stored in *.kmall raw format for bathymetry and backscatter and *.kmwcd format for watercolumn backscatter at CSIRO. There are 131 files totalling 17.8 GB of raw data and 131 files totalling 92.9 GB of watercolumn data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.kmall format are corrected for motion and position. GPS tide was computed using the EGM2008 model and applied to the processed data. Processed data has had outliers removed. Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report.

  • This record describes sub bottom profiler data collected on RV Investigator voyage IN2025_V05, 'Eruption, destruction and seafloor ecosystem recovery – Tonga 2022 eruption of the century', which departed Hobart on 10 Aug and ended in Brisbane on 01 Oct 2025 (local). The voyage’s first leg transited from Hobart to Nuku’alofa (10–19 Aug 2025), where science participants boarded. A mid-voyage transfer occurred on 05 Sep, and all science personnel disembarked in Nuku’alofa on 23 Sep before the final transit to Brisbane (23 Sep–1 Oct 2025). The Kongsberg SBP29 (sub bottom profiler) was used to acquire data containing the specular reflections at different sediment interfaces below the seafloor. The SBP120 provides a 3° by 3° angular resolution. The echosounder's frequency sweep range is from 2.5 to 9 kHz. The SBP29 was logged continuously for the extent of the voyage. Data are stored in *.raw (2002 files 22 GB) raw and *.seg (1991 files 21.9 GB) segy formats at CSIRO. The segy format data had a real time processing stream applied, which applies gain, a gain correction, matched filter with replica shaping, an attribute calculation for instantaneous amplitude and time variable gain. Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request
