  • This record describes sub bottom profiler data collected on RV Investigator sea trial voyage IN2015_E04, which departed Hobart 2015-04-25 and returned on 2015-04-28. The Kongsberg SBP120 (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 7 kHz. The SBP120 was logged for a few hours while testing for acoustic interference (01:30 2016-04-26 - 11:15 2016-04-26) Data are stored in *.raw (8 files 454 MB) raw and *.seg (8 files 448 MB) 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

  • This record describes the End of Voyage archive from the Marine National Facility RV Investigator trial voyage IN2015_E04. This is a trace metals and micronutrients trial voyage for the RV Investigator departing Hobart on the 26th April and returning to Hobart on the 28th April, 2015. This record describes the data collected by In-line aerosol sampling for trace metal analysis. Marine aerosols were collected on acid cleaned Whatman 41 47 mm filters housed inside an all PFA in line filtration system (Curtin University) in the aerosol lab. Duplicate samples were taken using 1) all PFA tubing from the aerosol in intake and 2) stainless tubing from the aerosol intake to the manifold and PFA tubing from the manifold to the filter. Flow meters and pumps (CSIRO, O&A, Aspendale). Sampling only occurred when the wind direction came from the "clean air" sector. Samples are stored frozen.

  • This record describes micronekton samples obtained with the Isaacs Kid midwater trawl, a single warp trawl with a 2m x 2m square mouth opening, single net with 6mm bar mesh lining and a reinforced 20mm bar outer lining. Seven samples, collected from 7 stations on the Marine National Facility RV Investigator Event voyage IN2015_E04, a trial voyage -trace metals and micronutrients- for the RV Investigator departing Hobart on the 25th April and returning to Hobart on the 28th April, 2015.

  • This record describes Underway (UWY) data collected from the Marine National Facility RV Investigator Event voyage IN2015_E04. This is a trace metals and micronutrients trial voyage for the RV Investigator departing Hobart on the 26th April and returning to Hobart on the 28th April, 2015. Standard Underway data is continuously recorded (refer to Attributes Overview): (1) Navigation data (NAV): Latitude, Longitude, Speed, Heading, course over ground, Gyros, and Doppler Log (dual GPS instrument). (2) Thermosalinograph (TSG): Water Salinity, flow-rate, Temperature, Fluorescence, and pCO2. (3) Atmospheric (MET): Humidity, Wind speed and direction (vane and ultrasonic), Radiometer, Pyranometer, PAR, Air temperature, Air pressure, rain and optical rain, Ozone and Trace gases (port and starboard instruments). Data are recorded at 5 second intervals. Near real-time data are available via the link "Visualisation tool for Underway Data." This dataset will not be processed, however raw unQC'd data can be supplied upon request. Additional information regarding this dataset is contained in the Cruise Summary Report for this voyage.

  • This record describes the End of Voyage archive from the Marine National Facility RV Investigator trial voyage IN2015_E04 Titled: Trace Metals and Micronutrients. This voyage departed Hobart on the 25th April and returned to Hobart on the 28th April, 2015. Data collected includes Underway (UWY), Acoustic Doppler Current Profiler (ADCP: 75, 150 kHz), SST Radiometer, Atmospheric data (Absorption Photometer, Nephelometer, Ozone, Radon), Greenhouse data (Aerodyne and Picarro), Underway pCO2, Echosounders (12, 18, 38, 70, 120, 200, 333, kHz), Multibeam (EM122, EM710, ME70 and SBP120) and Trace Metal Rosette (TMR) data.

  • This record describes some Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator, which are not part of research datasets and have not been processed or quality-controlled. This includes data from most "Gear trials" voyages (identified by the survey name suffix "_eNN"). Underway data from these voyages are usually not processed unless requested. While RV Investigator is at sea, standard Underway data are continuously recorded, consisting of: (1) Navigation data (NAV): Latitude, Longitude, Speed, Heading, Course Over Ground, Gyros, and Doppler Log (dual GPS instrument). (2) Thermosalinograph (TSG): Water Salinity, Flow-Rate, Temperature, Fluorescence, pCO2 and Optode/Oxygen. (3) Atmospheric (MET): Humidity, Wind Speed and Direction (vane and ultrasonic), Radiometer/Sea Surface Temperature, Pyranometer/Solar Radiation, Photosynthetically Active Radiation (PAR), Air Temperature, Air Pressure, Rain, Ozone and Trace Gases (port and starboard instruments). During the voyage, near real-time data are available from the MNF tool NRUD (Near Real-Time Underway Data) via the link "Visualisation tool for Underway Data" below. To request access after the voyage please contact the data custodian. The Underway data collected during research voyages (identified by the survey name suffix "_vNN") are processed and quality-controlled by the Marine National Facility (MNF). The processed datasets from these voyages are made available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII/CSV format) through a voyage-specific metadata record. Additional information regarding processed datasets is available in the Voyage Summary and/or the Data Processing Reports linked to the relevant metadata records.

  • This record describes the ISAR/SST Sea Surface Temperature data collected on the RV Investigator Voyages from 2014 onwards. The infrared SST autonomous radiometer (ISAR) is a self-calibrating instrument capable of measuring in situ sea surface skin temperature to an accuracy of 0.1 K. The SST Radiometer is mounted on the port bridge wing, approximately 19.593m above the summer load line. The RV Investigator ISAR skin SST data are also supplied both in real-time (http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/meteorological_sst_observations/catalog.html) and in delayed mode after reprocessing (e.g., http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/meteorological_sst_observations/2016/ISAR-QC/catalog.html). These reprocessed files will be particularly valuable for satellite SST validation (as the ISAR measures SST at the same depth as measured by satellites) and are currently (2017) being used by EUMETSAT for Sentinel-3 SST validation and to JMA and Oceans University China for Himawari-8 SST validation.
