Voyage Trials 2009/10. 1.1 Aim The aims of the voyage were to Re-fuel Macquarie Island, undertake Marine Science Trials (in preparation for Voyage 2), and undertake light re-supply & personnel transfer at Macquarie Island. This Report focuses on the Marine Science Trials (project 2652), the aims of which were to:    Test and refine Operation, Deployment and Retrieval methods, Develop/test JSA’s, SOP’s and train personnel. Test associated AAD equipment (camera systems, trawl modifications etc) and verify that ship systems are operational. The following systems were trialled on the voyage:      Beam trawl, (including camera systems , new drogues and sediment sampler), Long-line (including camera systems and new for’d recovery system), Demersal trawl underway instrumentation system Gear visualisation (tracking) system Works not achieved due to personnel & time constraints: 1.2  Additional deployment of Beam trawl  RMT system trials  Near real time data transfer to Kingston & BOM (IMOS)  Repairs to instrument failures during the voyage were still proceeding during the post-voyage port call. Timing and locations: The intention was to do the trials immediately following departure from Hobart. However, at this time of year weather is often bad. It was decided to try to re-fuel Macquarie Island during a predicted weather break at Macquarie Island, first up and we did the trials t23-25 October 2009. We conducted the trials off the east coast of Tasmania for the favourable weather conditions it provided. While we intended operations to run from 0600 to 2400 during trials, the lack of a second bosun limited this to 0600 to 2200. The 2 overlapping shifts (0600-1800 & 1000-2200) were used to assist in training and utilising daylight. However multiple ships winch problems delayed us repeatedly (all up for some hours,). The lack of experience within the IR’s in the crew also made operations slow and caused the Gear officers to heaver than expected work load. Overall these would have reduced the time available for trials by ~10 hours. The approximate timings were: Location Time (local= UT +11) Activity Hobart 12-Oct-2009 0800 On hire, load marine science equipment and Macquarie Island Cargo. 10003-DOC-0001-03-200910MarineDataVoyageReportVTrials.doc SCIENCE TECHNICAL SUPPORT Mq Is 10003-DOC-0001 Issue 3 Date: 2011/06/24 Marine Data Voyage Report 2009/10 Trials Page 5 of 23 12-Oct-2009 1500 depart to re-Fuel @ Selfs pt 13-Oct-2009 0900 Return to MQ4 14-Oct-2009 1800 depart Hobart, for Macquarie Island 17-Oct-2009 0630 anchor in Buckles Bay, refuel station Resupply Macca (in weather windows) 19-Oct-2009 1800 depart Mq Is, rough weather , but prepare en route.

(Unfortunately Troy & Max were unable to come, which placed significant workload on the remaining personnel, particularly John & Kim.) While the crew were down on numbers & experience and there were equipment problems, we want to thank the Officers, engineers and crew on Aurora for all their help, and the effort they put in. They enabled us to achieve most of our goals. 2 RECOMMENDATIONS / WORKS 2.1 Operations:  Have operational de-brief /planning session at beginning & end of each shift or operational changes. This is to include all practical analysis of data from the previous operations. This would have improved the decision making & communication processes. This should included Vessel and AAD management and key Science/operational personnel, and the information from…..  Analyse data before moving between sites or changing over equipment. This data is key to managing the operations. The late review of the Beam trawl video footage (after changing over the gear) caused us to miss an opportunity to correct/verify some issues with the deployment.  Have experienced ship’s crew, or employ more gear officers. The AAD gear officers were more crucial to the operation than desired due to lack of crew experience. If experienced crew cannot be obtained then employ more gear officers instead. 2.2 Gear  Have both depth and altitude sensors on Beam & Bottom trawls.  Don’t turn on cameras until last moment – they went flat during long delays.  Modify CTD bull horn (lower) and for’d bull horn (rotate) 2.3 Instrumentation & Computing  Make 2nd still camera chassis compatible with housing.  Investigate adding external battery pack to stills camera.  2.4 Complete works list. Laboratory The laboratories were not used on this voyage. 10003-DOC-0001-03-200910MarineDataVoyageReportVTrials.doc SCIENCE TECHNICAL SUPPORT 2.5 10003-DOC-0001 Issue 3 Date: 2011/06/24 Marine Data Voyage Report 2009/10 Trials Page 7 of 23 Reorders  2x spare Swan Digital wireless cameras SW233-ADW  Labeller for instrument room  Binder machine (for Documentation)  Daylight viewable laptop (for bridge display) 2.6 Ship faults The following ship faults were reported to the vessel: 3  Heli deck external 240 Vac outlets faulty (both port, one of starboard)  Cabin lights (most of bat-caves)  Trawl winch faults, o multiple breakdowns o Analogue pressure displays TASK DETAILS: The following are the Tasks listed for the trials voyage. 3.1 Long-line  For’d deck camera system installed and successfully tested.  New for’d recovery system. successfully tested  LIPs interface successfully tested  camera systems- successfully tested  JSA/SOP – updated and tested  Training - done Additional half day was spent developing & testing alternate recovery method to meet changed scientific goals. 3.2 Beam trawl,      camera systems – both systems were tested in water, however: o The first deployment was delayed causing the stills camera batteries to run out.

Better bathymetry can be obtained by postprocessing the raw acoustic data that was collected by the acoustics system. 4.2.2 GPS Data There were 2 GPS systems used in the main data set. The Ashtech model 3DF receiver (including pitch/roll/heading) located on aft gantry JRC GPS located on aft gantry. The parameters recorded are in NMEA sentences: Both functioned well during voyage. 4.2.3 Flow The TSG and Fluorometer uncontaminated seawater flows are measured by Krohn IFC 020 D Electromagnetic flow meters. (TSG with s/n R08207b, and Fluorometer with s/n R08207a) Last calibration was 2009. There was a problem with the Interface card that caused almost no data to be obtained from the Fluorometer Flow meter, and the TSG Flow to be missing from ~2009-Oct-21 0600 while the fault was being investigated (although flow continued at around previous values.) 4.2.4 Thermosalinograph The Thermosalinograph used was SBE 21 s/n 2111393-1781. This was calibrated in 2009 at CSIRO. The logged parameters are: Conductivity, Temperature & salinity. The thermosalinograph is still being commissioned … (the spare is in the USA being repaired…) 4.2.5 Gyro Heading The ships Gyro’s are Sperry Mk-37 Mod D/E gyrocompasses. The Gyro heading converter did not start correctly. The converter was power-cycled 2009/10/14 ~2200 which fixed it. 4.2.6 Wind Speed and Direction Young anemometers 05106 –MA mounted on main mast. 4.2.7 Humidity and Air Temp The starboard temperature/humidity sensor was:  Vailsala HMP 233 / 3.01 ,CPU serial nr : X0520018 , PRB serial nr :  gave erroneous data for most of the voyage until replaced on with:  o HMP 233 / 3.01, CPU serial nr : W3740014, PRB serial nr : o cal. date : 20080619 152 128 Mounted above observation shelter on top of bridge. 10003-DOC-0001-03-200910MarineDataVoyageReportVTrials.doc SCIENCE TECHNICAL SUPPORT 10003-DOC-0001 Issue 3 Date: 2011/06/24 Marine Data Voyage Report 2009/10 Trials Page 11 of 23 The port temperature/humidity sensor was:  Vailsala HMP 233 / 3.01 CPU serial nr : X0520019  PRB serial nr :  Last calibration 2009.  Mounted above observation shelter on top of bridge. 4.2.8 152 Licor The starboard Licor only was installed at the end of the voyage.

This system records all the raw data from the instrumentation into text files which are archived at the end of the voyage. The logging system converts the raw data into scientific units and then sends the data over the ships network for further processing or viewing in real time. The system also records the processed information in a database at set intervals, which is then available for display or downloading and analysis. The Aanderra Optode Oxygen sensor is the only instrument data that is written to the database at 30 seconds intervals. All other instruments write data to the database every 10 seconds. For some instruments the instrument reading is compared to known limits for the instrument, and if the data is outside these values the data is marked as bad in the database. No other quality control or checking is usually performed during a voyage. This database is transferred to the Australian Antarctic Data Centre (AADC) at the end of the voyage and is available from the AAD web site (www.aad.gov.au) for downloading. From the 2010/11 season database data will be automatically sent back to the AADC every ½ hour and should be available for download within a few hours of the data being collected on board the Aurora Australis. Not all instruments on the Aurora are connected to the logging system and not all the data from the connected instruments and record in the raw data text files is distributed over the network or saved to the database. Before any data is used it should be quality checked to ensure that it is valid. Please contain the AADC for further details on the availability of instrument raw data. The instruments connected are classified into 4 main categories: 7.1.1 Navigation Instruments Various GPS instruments are used to record the position, heading, speed pitch and roll of the Aurora Australis. A depth reading beneath the ships keel is obtained from a 12 kHz Simrad sounder, see the Acoustic instruments for further details. The following instruments are usually installed: 7.1.1.1 JRC GPS-112 GPS Receiver Two GPS units are installed, one on the bridge superstructure and one at the stern of the vessel. These instruments are used to obtain the ships position, course over ground, speed over ground and a UTC time reference. The logged parameters are: Latitude, Longitude, course over ground (GPS_COG), speed over ground (GPS_SOG) The name in brackets is the database parameter name and is used to download underway data. The logging system will switch before the forward and aft GPS units if a failure occurs or is unable to obtain a position fix. This can result in sudden jumps in position (Latitude and Longitude). As data is transferred to the AADC post voyage missing positions for short durations (Usually less than 1 hour) are calculated from known good positions and entered into the database so that a continuous 10 second track is available. It is not currently possible from the downloaded data from the AADC to ascertain which GPS unit was used or if the value is an actual GPS position or calculated value. If you require verified track information please contact the AADC. 7.1.1.2 Ashtech ADU2 GPS Receiver The Ashtech unit is use to obtain the ships pitch and roll and true heading. The logged parameters are: maximum pitch (PITCH_MAX), minimum pitch (PITCH_MIN), maximum roll (ROLL_MAX), minimum roll (ROLL_MIN) and true heading (TRUE_HEAD). The pitch and roll minimums and maximums are calculated over a 10 second period. The true heading value is used on the Aurora by the Piscatus trawling software, but this parameter is not transferred to the AADC and is not available for download. 10003-DOC-0001-03-200910MarineDataVoyageReportVTrials.doc SCIENCE TECHNICAL SUPPORT 7.1.1.3 10003-DOC-0001 Issue 3 Date: 2011/06/24 Marine Data Voyage Report 2009/10 Trials Page 18 of 23 Sperry Mk-37 Mod D/E Gyrocompass This unit is used to obtain the ships true heading. The logged parameters are: True heading (SH) 7.1.2 Meteorological Instruments These Instruments record wind direction and speed, air temperature and humidity, precipitation, barometric pressure and solar radiation. The following instruments are usually installed: 7.1.2.1 Vaisala HMP223 Temperature and Humidity Two instruments are installed, one on the port side of the monkey isle on the Whale Observers shelter and one on the starboard side. This instrument can be affected by the ships exhaust. The wind direction should be checked and the upwind instrument used. The logged parameters are: Port and starboard temperature and humidity (A_TEMP_P, A_TEMP_S, HUMID_P, HUMID_S) The temperature is check to be within -100 to 150 degrees centigrade, and the humidity checked to be within 0 to 100%. Any data outside of these limits is marked as bad. Occasionally the humidity recorded by the instrument exceeds 100%, and the data is marked as bad. 7.1.2.2 Vaisala PTB220 Barometer This instrument measures atmospheric pressure and the 3 hours trend. The logged parameters are: Pressure (BAR), 3 hours trend (BAR_T) 7.1.2.3 RM Young 05103 Wind Anemometers Two instruments are installed at the top of the radar mast, approximately 30 meters above the water line. The instruments can be affected by the mast superstructure and radio domes, and the upwind instrument should be used. The true wind speed and direction is calculated as a vector from  the apparent wind direction and speed  the ships speed and course and  Speed over ground from the GPS-112 GPS units. When the ship is travelling at a speed of less than 3 knots, the ships true heading from the Sperry gyrocompass is used instead of the GPS course over ground value to calculate true wind direction. The logged parameters are: Port and Starboard apparent wind direction and speed (WDPA, WDSA, WPSA, WSSA), true wind direction and speed (WDPT, WDST, WPST, WSST) 7.1.2.4 Young 50201 Precipitation Gauge This instrument measures accumulated precipitation. It is mounted on the port side of the monkey isle. The instrument accumulates to 50mm, then resets to zero and starts to accumulate again. The logged parameters are: Precipitation in mm (RAIN) 10003-DOC-0001-03-200910MarineDataVoyageReportVTrials.doc SCIENCE TECHNICAL SUPPORT 7.1.2.5 10003-DOC-0001 Issue 3 Date: 2011/06/24 Marine Data Voyage Report 2009/10 Trials Page 19 of 23 Optical Scientific ORG 815 Optical Rain Gauge This instrument was not installed for the 2009/10 season. 7.1.2.6 Middleton SK01-DP2 PAR Sensor Two Middleton PAR sensors are installed, one on the port side of the monkey isle on the Whale Observers shelter and one on the starboard side. These optical instruments can be affected by atmospheric conditions, snow, ice and dirt occluding the sensor and shading from the ships superstructure. The PAR sensor measure photosynthenically active radiation in the 400-700nm band. T he logged parameters are: Port and Starboard PAR (PAR_R_P, PAR_R_S) 7.1.2.7 Middleton EQ08 Solar Pyranometer Two Middleton solar radiation sensors are installed, one on the port side of the monkey isle on the Whale Observers shelter and one on the starboard side. These optical instruments can be affected by atmospheric conditions, snow, ice and dirt occluding the sensor and shading from the ships superstructure. These sensors measure total solar radiation in the 300-3000nm band. The logged parameters are: Port and Starboard total solar radiation (SOLAR_R_P, SOLAR_R_S) 7.1.2.8 Eppley PIR, Precision IR Radiometer This instrument was not operational for the 2009/10 season 7.1.2.9 Solar Light 501V3, UV Biometer This instrument was not installed for the 2009/10 season 7.1.2.10 Eppley UVB, Total UVB Radiation This instrument was not installed for the 2009/10 season 7.1.2.11 Licor LI-190SZ PAR Sensor The Licor PAR sensor was decommissioned after the 2009/10 trials voyage and replaced with the Middleton SK-01 PAR sensor. 7.1.3 Sea Water Instruments These Instruments record the sea water temperature, salinity, fluorescence, oxygen content and the flow rate of the sea water thought the instruments. The following instruments are usually installed: 7.1.3.1 Seabird SBE-21 Thermosalinograph (TSG) This instrument is used to measure the salinity and conductivity of the sea water. The logged parameters are: Conductivity (TSG_CNDUCT), Temperature (TSG_TEMP) & salinity (TSG_SALIN). Before data from this instrument is used the TSG_FLOW parameter should be check to ensure that it is approximately 8 litres per minute. Other checks would be to compare the TSG_TEMP with the uncontaminated seawater temperature (W_TEMP). The TSG temperature should be virtually identical to the uncontaminated seawater temperature. In the past it has on occasions been warmer as the flow through the pipe work feeding the TSG was considerably lower than at present, which allowed the uncontaminated seawater to warm as it travelled through the ship to the TSG from the water 10003-DOC-0001-03-200910MarineDataVoyageReportVTrials.doc SCIENCE TECHNICAL SUPPORT 10003-DOC-0001 Issue 3 Date: 2011/06/24 Marine Data Voyage Report 2009/10 Trials Page 20 of 23 inlet to the TSG. Modifications were made prior to the 09-10 season to increase the uncontaminated seawater flow to the Ocean Lab. The overboard discharge point is now located adjacent to the lab which greatly improved the flushing, & has eliminated localised heating effects caused by fluctuating flows. 7.1.3.2 WetLabs RMA 2948 Wetstar Chlorophyll sensor (Fluorometer) The Fluorometer is used to measure the fluorescence of the sea water. This gives a good indication of the amount of biological material in the water. The logged parameters are: Fluorescence (FLU_VALUE). Before data from this instrument is used the FLU_FLOW parameter should be check to ensure that it is approximately 4 litres per minute. 7.1.3.3 Krone IFM5020K flowmeters Two meters are installed to monitor the water flow through the SBE21 Thermosalinograph and the Fluorometer. The logged parameters are: TSG flow (TSG_FLOW) and Fluorometer flow (FLU_FLOW). Small ice fragments can partially block the water intake which can result in reduced or erratic flows. This is especially prevalent during ice breaking. 7.1.3.4 Aanderra Optode 3835 Oxygen sensor This instrument is mounted in the same housing as the Fluorometer and measures the dissolved oxygen concentration. The underway logging systems uses data from the Thermosaliograph to calculated a corrected value. The logged parameters are: oxygen concentration (OPTODE_O2), D-Phase (OPTODE_DPH), Salinity (OPTODE_SAL), temperature (OPTODE_WT) and corrected oxygen content (CORRECT_O2). Before data from this instrument is used the FLU_FLOW parameter should be check to ensure that it is approximately 4 litres per minute. The temperature and salinity can also be cross referenced to the TSG. 7.1.3.5 Seabird SBE-38 Water temperature probe This instrument is installed close to the sea water inlet on the Aurora and gives an accurate water temperature reading. Before data from this instrument is used the TSG_FLOW or FLU_FLOW parameter should be check to ensure that there is water flow over the instrument. 7.1.4 Acoustic Instruments These instruments record the bottom depth and profile, biological activity in the water column and currents at various depths. Only the depth calculated from the Simrad 12 kHz sounder interface is processed by the underway logging system. All other data from these instruments is recorded on disk and transferred to the AADC at the end of the voyage. The following instruments are usually installed: 7.1.4.1 Simrad EK60 12 kHz GPT (Bathy) The Simrad 12kHz GPT acoustic sounder is used to profile the sea floor. It also calculated a depth. The raw data for this instrument is transferred to the AADC at the end of the voyage. The logged parameter is: Depth (DEPTH) The depth calculation is affect by any sea ice or turbulence under the hull that are present during ice breaking or rough weather. The operation of the ships thrusters used to maintain a stationary position also affects the reliability of the depth calculation. It is common during ice breaking or thrusters operation the bottom depth cannot be determined by the 10003-DOC-0001-03-200910MarineDataVoyageReportVTrials.doc SCIENCE TECHNICAL SUPPORT 10003-DOC-0001 Issue 3 Date: 2011/06/24 Marine Data Voyage Report 2009/10 Trials Page 21 of 23 software and a random value (Usually very deep) or zero is recorded. The 12 kHz is also not able to calculate depths in shallow waters. If accurate values are required the raw data must be manually reprocessed and the depth recalculated. The data transferred to the AADC is usually not quality checked. 7.1.4.2 Simrad 38 kHz, 120 kHz & 200 kHz GPT (Bio) These three sounders are used to profile biological material in the water column. The higher the frequency of the transducer the more resolution can be obtain, but the beam absorption is higher so less depth can be sampled. The raw data from these instruments are transferred to the AADC at the completion of the voyage. 7.1.4.3 RDI OSADCP 150kHz Acoustic Doppler Current Profiler (ADCP) This instrument determines current depths at different depths. This instrument relies on information from the navigation Ashtech unit to correct for the ships pitch and roll. The raw data is transferred to the AADC at the completion of the voyage. 7.2 Instrument Data Collected Every raw data sample collected from the scientific instruments connected to the underway logging system is written to a text file. These text files are transferred to the AADC at the completion of the voyage. The database contains 10 second latitude and longitude ships track entries from the attached GPS units and entries (usually every 10 seconds) for each instrument parameter that is processed. The ships track latitude and longitude is recorded in the database every 10 seconds as decimal degrees to 6 decimal places. All timestamps are in UTC. All other instrument data is recorded in the database, usually every 10 seconds as a UTC timestamp, 10 character parameter code, floating point value and quality flag. The quality flag is a small integer value, with a value of 0 representing bad data, and a value of 1 for good data. The actual instruments installed and parameters recorded can vary depending on the scientific requirements. For this season the following instruments parameters where used, check the Metadata section in this document for individual voyages as not all of these parameters where available on every voyage. 7.2.1 Navigation Parameters Parameter Description Units of measure Instrument Timestamp (Note 1.)
