  • These data sets describe the toxicity of lead, coppyer, zinc and cadmium spiked seawater to the juveniles of Abatus ingens and Abatus nimrodi. Metals were tested separately over exposure periods of 96 and 240 hours. The experimental endpoint was mortality as defined by cessation of observable movement. The coding system for the data files is J(juvenile)_An (Abatus nimrodi) or Ai (Abatus ingens) - Metal name_Dates of the experiment_ the period of the observation (96 hour or 240 hour). This work falls under the umbrella project ASAC_2201. The fields in this dataset are: Species Toxicant Date Replicate Concentration Moving pH Salinity Dissolved Oxygen

  • Data collected from O'Gorman rocks near Davis Station between February 2004 to January 2005. Data were collected using a Yellow Science Industries 6600 Sonde. Vertical profiles of Temperature, Salinity, Conductivity, Dissolved Oxygen, Photosynthetically Active Radiation were collected. Each Sampling date/time and depths were recorded. The data are stored in spreadsheet form, and saved as a comma separated values text file. This work was carried out as part of ASAC project 40.

  • This data set describes the toxicity of marine sediment spiked with contaminated soil from Thala Valley tip site at Casey. The temperate heart urchin species Echinocardium cordatum was exposed for up to 10 days with daily observations of the degree of burial of the animals.

  • Oceanographic measurements were conducted along WOCE Southern Ocean meridional section SR3 between Tasmania and Antarctica from August to September 1996. A total of 71 CTD vertical profile stations were taken, most to near bottom. Over 1500 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), dissolved inorganic carbon, alkalinity, carbon isotopes, primary productivity, and biological parameters, using a 24 bottle rosette sampler. Measurement and data processing techniques are summarised, and a summary of the data are presented in graphical and tabular form. The fields in this dataset are: oceanography ship station number date start time bottom time finish time cruise start position bottom position finish position maximum position bottom depth pressure temperature (T-90) salinity sigma-T specific volume anomaly geopotential anomaly dissolved oxygen fluorescence photosynthetically active radiation

  • Oceanographic measurements were conducted north of Heard Island from August 1993 to October 1993. A total of 58 CTD (conductivity, temperature and depth) vertical profile stations were taken, most to near bottom. Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), chlorofluorocarbons, helium, tritium, dissolved inorganic carbon, alkalinity, carbon isotopes, dissolved organic carbon, dimethyl sulphide/dimethyl sulphoniopropionate, iodate/iodide, oxygen 18, primary productivity, and biological parameters, using a 24 bottle rosette sampler. CTD salinity data have been calibrated against bottle samples. Upcast CTD burst data were no longer available, however comparison of bottle samples to CTD data from the equivalent downcast pressures gives a salinity accuracy of approximately 0.005 (PSS78). The bottle data file contains salinities and dissolved oxygens. Nutrient data exist only in files output from the laboratory analysis program 'DAPA', and are contained on floppy disks held by Andrew Forbes (CSIRO). Measurement and data processing techniques are described, and a summary of the data are presented in graphical and tabular form.

  • Oceanographic measurements were conducted in the Subantarctic Zone south of Tasmania in March 1998. A total of 97 CTD vertical profiles were taken. Over 800 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), dissolved inorganic carbon, alkalinity, carbon isotopes, dissolved organic carbon, N2O isotopes, pH, oxygen-18, barium, nitrogen-15, arsenic, ammonia, DMS/P, bacteria, silicon-32, particulate silicon, productivity, ETS, pigments, species counts, cytometry, particulate organic carbon and nitrogen, urea, copper and iron, using a 24 bottle rosette sampler. Four sediment trap moorings were recovered, and two were redeployed.

  • Oceanographic measurements were conducted in the Southern Ocean Indian sector during the southern summer of 2004/2005 on Aurora Australis voyage au0403, V3 2004/2005. Data were collected during a complete occupation of CLIVAR meridional section I9S; and then along a transect up the northeastern flank of the Kerguelen Plateau, south across the Princess Elizabeth Trough and onward to the Antarctic continental shelf. A total of 115 CTD vertical profile stations were taken, most to within 30 m of the bottom. Over 2450 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients, CFCs, dissolved inorganic carbon, alkalinity, oxygen-18, methane, selenium and biological parameters, using a 24 bottle rosette sampler. Full depth current profiles were collected by a lowered acoustic Doppler profiler (LADCP) attached to the rosette package, while near surface current data were collected by a ship mounted ADCP. An array of 8 current meter and thermosalinograph moorings, deployed 2 years earlier on cruise au0304, were recovered from the vicinity of the Kerguelen Plateau. Ship's underway data (including bathymetry, met. sensors and sea surface parameters) are included in the cruise data set; an offset correction was applied to the underway sea surface salinity and temperature data, derived from comparison with near surface CTD data. A summary of all data and important data quality information is presented in the data report. LADCP data are not included in this data set. This work was completed as part of ASAC projects 2312 and 2572.

  • Oceanographic measurements were conducted between Tasmania and Heard Island, and then around Heard and McDonald Islands from May to July 1990. A total of 96 CTD (conductivity, temperature and depth) vertical profile stations were taken, most to near bottom. No Niskin bottle water data are available unfortunately (for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), dissolved inorganic carbon, alkalinity, carbon isotopes, primary productivity, and biological parameters. Measurement and data processing techniques are summarised, and a summary of the data are presented in graphical and tabular form.

  • Oceanographic measurements were conducted in the vicinity of the Mertz Polynya, encompassing 2 consecutive seasonal cycles from 1998 to 2000. In the southern winter of 1999, a total of 92 CTD/LADCP vertical profile stations were taken, most to within 20 m of the bottom, with 3 laps completed around the boundary of a box adjacent to the Mertz Glacier. Over 700 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients, oxygen 18, dimethyl sulphide, and biological parameters, using a 12 bottle rosette sampler mounted on a 24 bottle frame. Additional CTD vertical profiles were taken in April 1998, July 1998 and February 2000. Near surface current data were collected on all cruises using ship mounted ADCP. Two mooring arrays comprising thermosalinographs, current meters and upward looking sonars were deployed in the region of the Polynya. The first array of 7 moorings was deployed in April 1998. The second array of 4 moorings was deployed in the winter of 1999. All 11 Polynya moorings were recovered in February 2000. A summary of all data and data quality is presented in the data report. This work was completed as part of ASAC projects 2223 and 189.
