Survey InvestigatorDescription
FR 09/93

P. Nichols (CSIRO), including other PI's Cruise FR 09/93 was undertaken to survey the outfalls and distribution of metallic and organic contaminants in shelf sediments in coastal waters off Sydney. A total of 155 stations were occupied with surface sediment collected at all sites. Station sampling included: CTDs, ADCPs, sediment grabs and coring, zoo plankton tows and other associated instrumentation. Numerous water, biological and sediment samples were collected for analyses aboard and for laboratory study. Additional sites were sampled at Providential Head and Cape Banks as part of a research contract performed by the Division of Oceanography for the Sutherland Shire Council.
FR 01/92

P. Nichols & R. Leeming (CSIRO) Cruise FR 01/92 forms part of the Sydney Outfall Studies. This cruise was undertaken to trace sewage in Sydney's coastal waters and sediments using organic markers. Repeat sampling and subsequent chemical analyses for sites examined during cruise FR 13/89 in Sydney's nearshore waters was conducted. Survey methods included CTDs, ADCP, underway instrumentation, grabs, deployment and recovery of chemistry moorings at DOOM and DOOB. Water and sediment samples, underway surface water temperature, salinity, pH and fluorescence data were collected for on board and laboratory analyses. Appropriate sample collection and preparation facilites were provided for external organisations (ANSTO, metals; CSIRO Centre for Advanced Analytical Chemistry, rapid detection methods; Sydney Water Board, viruses and microbiology; NSW State Pollution control Commission, oceanography, microbiology; University of Western Sydney, microbiology) undertaking collaborative studies with the Division of Oceanography.
FR 04/91

P. Nichols, P. Craig (CSIRO) Cruise FR 04/91 was undertaken to retrieve moorings (previously deployed during cruise FR 01/91), and to collect water samples for routine hydrology and other chemical assays; to collect sediment samples to determine chemical levels; to collect atmospheric gas samples for the analysis of CO2 and other tracer gases; to collect sponges to detect sources of chemical, biochemical and pharmacological useful substances from the Bass Strait region and Sydney's deep water ocean outfall at Malabar (DOOM) offshore from Botany Bay, NSW. Survey methods included ADCP, CTDs, grabs, cores, beam trawls, underway and other associated instrumentation. Samples were collected for on board and laboratory analysis. Related cruise FR 01/91.
FR 01/91

P. Nichols & P. Craig (CSIRO), J. Middleton (UNSW) Cruise FR 01/91 was principally a deployment cruise. 11 moorings were laid for the "Bass Strait Interdisciplinary Study" and 5 moorings were laid for the "Low Frequency Circulation Study at the western end of Bass Strait". The period of the instrument deployments was planned to cover the time of summer stratification through to winter mixing. 27 CTD stations were conducted and underway instrumentation recorded continously. The Strait appeared to be well mixed vertically down to about 50 m, horizontally stratified, warmest water, around 17.6 degrees C, in the NE, and the coolest in the SW, at 15.3 degrees C. There appears to be a pool of cold water in the deep central Strait where the depth exceeds 50 m. The western end of the Strait, between King Island and Cape Otway is strongly stratified in the vertical. The CTD sections do not resolve the NW sector of the Strait in which the transition from strong to zero stratification occurs. Water samples were collected for chemical analysis.
