  • This research facilitated Australian leadership in the new international GEOTRACES program (www.geotraces.org), studying a wide range of chemical, physical and biological processes involved in the cycling and supply of trace elements and their isotopes (TEIs) in the ocean, and their sensitivity to changing environmental and climatic conditions. The GEOTRACES survey gp13 was the first to map the three-dimensional distribution of of TEIs in the southwest Pacific Ocean, and conducted experiments to understand their sources, sinks and internal cycling. This dataset sourced from the GEOTRACES data portal includes copper, cadmium, iron, manganese, lead and zinc concentration measurements at depths up to 6000 m.

  • 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.

    Bathurst Harbour and Macquarie Harbour are estuarine systems on the west coast of Tasmania, Australia. While Macquarie Harbour is grossly polluted from mine operations via contamination of the King River, Bathurst Harbour is surrounded by World Heritage wilderness and is essentially free of anthropogenic influences. The vegetation of the catchments of both harbours is similar and the waters of both harbours are deep brown due to the presence of humic substances. A hydrographic survey of the pristine Bathurst Harbour estuarine system was carried out over 4 days in January/February of 1990 (Austral Summer). Sampling and laboratory analyses for a range of trace elements (Cd, Co, Cu, Fe, Mn, Ni, and Zn) were made using non-contaminating procedures.

While Macquarie Harbour is grossly polluted from mine operations via contamination of the King River, Bathurst Harbour is surrounded by World Heritage wilderness and is essentially free of anthropogenic influences.

Sampling and laboratory analyses for a range of trace elements (Cd, Co, Cu, Fe, Mn, Ni, and Zn) were made using non-contaminating procedures. Comparison of results from this survey, with those from Macquarie Harbour in the summer of 1989, provided a clearer assessment of the effects of mining operations on trace metal concentrations in Macquarie Harbour.

  • The Australian Equatorial JGOFS (OzGOFS) investigations were conducted on three cruises in 1990, 1992 and 1993 on transects along between 6oN and 2oS along 147oE and between about 12oS to 10oN along 155oE. FR 08/90 was made between 2-17 October 1990; FR 05/92 between 15 June and 13 July 1992, and FR 08/93 between 5 November and 1 December 1993. Data from the two legs of FR 05/92 have been combined into a single “cruise” on the disk. The cruise in 1990 (FR 08/90) was carried out after the 1988/89 La Nina but before the 1991/92 El Nino event. The cruises in 1992 (FR 05/92) and 1993 (FR 08/93) were done during the middle and end of a prolonged El Nino event. The objectives of the cruises were: 1) To measure vertical and horizontal profiles of pH, carbon dioxide and fluorescence in waters of the western equatorial Pacific Ocean. 2) To study the primary and secondary productivity of these waters. 3) To study the physical, chemical and biological processes that determines the vertical fluxes of carbon across the air-sea interface and within the water column. 4) To study the chemical, physical and biological processes leading to increased biomass along the equator at the western boundary of the Pacific Ocean. 5) To use chemical methods, such as lipid and pigment analyses, to characterize the phytoplankton community structure within different water masses. Data includes Acoustic Doppler Current Profiler (ADCP) data, chlorophyll-a and phytoplankton pigments, CTD, cyanobacteria and bacteria, natural radionuclides, nutrients, primary production, sediment trap data, surface fCO2, trace metals and zooplankton data.
