|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.|
