This dataset contains the Acoustic Doppler Current Profiler (ADCP) data collected on Southern Surveyor voyage SS2011_v07. The voyage took place from Hobart to south-west of Tasmania 47 S and 140 E and return to Hobart between the 22nd and 27th of November, 2011. This dataset was processed and then archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. NOTE Processing of ADCP data used a revised CODAS system resulting in a new data structure, please see attributes for the new netCDF file structure. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report.
This dataset contains the Conductivity-Temperature-Depth (CTD) data collected on Southern Surveyor voyage SS2011_v07.The voyage took place from Hobart to south-west of Tasmania 47 S and 140 E and return to Hobart between the 22nd and 27th of November, 2011. This dataset has been processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report (as available).
This dataset contains the Hydrology (HYD) data collected on Southern Surveyor voyage ss2011_V07.The voyage took place from Hobart to south-west of Tasmania 47 S and 140 E and return to Hobart between the 22nd and 27th of November, 2011. This dataset has been processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. Southern Surveyor on-voyage hydrology data are typically obtained from water samples collected in Niskin bottles at various depths during each CTD cast. Parameters measured normally comprise temperature, salinity, dissolved oxygen, phosphate, nitrate, silicate, and nitrite.
This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS2011_V07. The voyage took place from Hobart to south-west of Tasmania 47 S and 140 E and return to Hobart between the 22nd and 27th of November, 2011. This dataset has been processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder, Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data includes atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data from "IMOS" (Integrated Marine Observing System) sensors are also included. The sensors are port and starboard radiometers and pyranometers, wind speed; rain and rainrate. Data are recorded at 5 second intervals and stored in NetCDF format. For Public Access data (.csv files, 10 sec and 5 min intervals). See "Download Public Underway data and Processing Reports" link for details.
The IMOS Bio-Acoustic Ship Of Opportunity (BA-SOOP) sub-facility is part of a major international effort that aims to determine the distribution and abundance of mid-trophic level organisms (meso-zooplanktonic and micro-nektonic) preyed by top predators (sharks, tuna) by using commercial fishing vessels (SOOP), research vessels, automated oceanic moorings, acoustic recorders, drifters and gliders. The MAAS (Mid-trophic Automatic Acoustic Sampler) project targets two levels of technology: a high level suited to large platforms such as fixed moorings, vessels or AUV and low level platforms adapted to a large number of autonomous drifters. BA-SOOP commenced on the 1st of July 2010 to collect underway acoustic data from commercial fishing and research vessels. At present, nine vessels are participating in the BA-SOOP program. Six are commercial fishing vessels that have agreed to record data during transits to and from fishing grounds. The remaining three are scientific research vessels collecting underway acoustic data during transits and science operations. Bio acoustic signals measure the distribution of mid-water prey species (micronekton) such as small fish, squid, krill and jellyfish. Micronekton form the core of the ocean food web, transferring energy from primary producers at the ocean surface to top predators such as tunas, billfish, sharks, seals and seabirds. The mass and distribution of micronekton reflects broad-scale patterns in the structure and function of the ocean, as well as the dynamics of marine ecosystems. The mapping complements established observing systems such as physical sampling of ocean currents, surveys of ocean chemistry and biology (plankton and zooplankton), and electronic tagging and tracking of large marine fish and mammals. The combined information greatly enhances the capacity of marine scientists to monitor shifts in food availability over time, assisting in the near real-time monitoring and modelling of oceanography, ecosystems, fisheries and climate change, and in understanding the behaviour of top predators. A full metadata record is also stored in each netCDF file. The document SOOP-BA NetCDF manual v1.0.doc describes the netCDF format and metadata fields that have been defined.
