Description: in2017_c02: 1. Conduct a bathymetric survey to improve navigational safety between Wilson’s Promontory and the Hogan Group. Survey to be conducted in accordance with International Hydrographic Organisation standards S44 Order 1a. 2. Improve the charting standard of charts AUSENC 439146, 439147, 440146, 440147 and AUS 148, 357, 487, 802 3. Assess current Hydrographic surveying skill sets for nautical charting activities. 4. Assess equipment capabilities for geospatial data collection. 5. Assess the vessel capabilities for conducting geospatial data collection activities in remote and varying environmental conditions. in2018_c01: To gain an understanding of the nature of the marine environment in the survey area and to collect meteorological and oceanographic data in the area to contribute to current modelling systems. Additionally, this information will benefit the management of the Commonwealth Marine Reserve at Hogan Island.

Emily Jateff (Australian National Maritime Museum) RV Investigator research voyage IN2019_V07, titled “RAN Hydrographic and Maritime Heritage Surveys." Voyage objectives: 1) Australian Hydrographic Office Survey of Bass Strait - Completion of mapping of Sub Area A within Bass Strait (outstanding from IN2018_C01): ~24 hours using EM710. 2) Historic Shipwreck Surveys - Conduct surveys of the purported site of SS Federal and opportunistic survey of three unidentified targets. - Multibeam survey of SS Queensland, which doubles as a multibeam calibration target. 3) Training and Equipment Trialling - CTD casts including hydrochemistry analysis. Test altimeter operation during very shallow (~80m) CTD cast (conduct in area with existing bathymetry data). - Triaxus tows. - Operation of ADCPs. - Drop camera deployment (potentially at located shipwreck sites). - Multibeam patch test calibrations: one in shallow water and one in deep water; approximately 6 hours required for each. - Multibeam backscatter calibration lines: conduct during transit into and out of Storm Bay. - Deployment of RapidCAST SVP and development of associated Standard Operating Procedures (SOPs) for its use: can occur while underway (at a slightly reduced speed). - Trialling of new Seaspy magnetometer prior to IN2019_V04: each deployment will occur by hand during daylight hours, take approximately 30-45 mins and can occur while underway (at a slightly reduced speed). - Trialling of the new Brenke sled system. - Training of new personnel in the deployment of other equipment, including the multicorer and possibly, the Smith Mac grab. - CTD casts including hydrochemistry analysis. At least 3-5 shallow CTDs and 3-5 CTDs conducted at depths of >3000 m, with a maximum of 2 CTDs per 24 hours. - Training of new personnel in the Voyage Manager role and general vessel operations. 4) Seabird and Marine Mammal Observations Seabird at sea data will be collected according to the method described by the BIOMASS Working Party on Bird Ecology. This method has been used by Australian Antarctic Division (AAD) personnel since 1980/81 and reflects the standard protocol for obtaining seabird at sea data. Observations will be made continuously while the vessel is underway during daylight hours from the specifically designed Observation Deck on board Investigator. Observations of marine mammals are also included (in the absence of dedicated marine mammal observers) using standard protocols. Observation of marine debris are also recorded.
IN2018_C01

[details]
LCDR Nigel Townsend (RAN) RV Investigator research voyage in2018_c01, titled “RAN Hydrographic Survey.” Voyage objectives: To facilitate safe navigation for international and coastal shipping. This survey will also improve confidence for subsurface navigation in Bass Strait. The overall focus for this survey is to conduct a modern survey in the primary shipping route through Bass Strait. The MET and OC observations and data collection have three purposes, namely: a) To collect data from which a sonar or radar range prediction can be calculated (humidity, pressure, temperature, wind speed, ocean temperature and salinity profile, currents through depth, sediment type, sub-bottom classification (where possible); - Sub-bottom classification will incorporate sediment samples taken using the MNF Smith-McIntyre Grab. Samples will be kept and stored with Geoscience Australia (GA). b) To identify what observations can be conducted concurrently, and what observations have limiting factors that preclude concurrent operations/survey activity; c) To develop understanding of what types, accuracy and formats of data can be collected and how this might be of use to the scientific community and Defence. A full GSM Survey Procedure pertaining to the hydrographic surveying elements of the primary voyage are included in appendix 1 – GSM Hydrographic Survey Procedure.
