    This dataset contains data from pollution monitoring in Jervis Bay, NSW. The data were obtained from various sites around Jervis Bay at different times between October 1988 and July 1991. Samples for trace metals from sediments were determined, together with grain size. Mercury in the tissues of Red morwong (Cheilodactylus fuscus), Oysters (Ostrea angasi), Mussels (Trichomya hirsuta) and heavy metals in the leaves of Posidonia australis and Zostera sp. were determined. Organochlorides and hydrocarbons from sediments, water column and biota were also determined. Tributyl tin experiments were conducted in tanks. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

  • This record describes the sediment data collected from the Marine National Facility RV Investigator Event Voyage IN2015_E02, departing Hobart on the 7th April and returning to Hobart on the 14th April, 2015. The primary voyage objective was to deploy a specific sub-set of sampling equipment related to benthic biology, to establish processes, procedures and work flows in places such as the rear deck and sample processing laboratories. The primary equipment trialled was the MNF Deep Tow Camera, MNF Beam trawl, MNF Benthic (Sherman) Sled, and MNF Smith-McIntyre Grab, and the CSIRO-supplied Integrated Corer Platform (ICP), DeepBRUVs lander, and fishing dropline. The Integrated Coring Platform ( ICP) combines a number of technologies to maximise sampling in a single deployment. The ICP is built around a 6 barrel corer (KC, Denmark) and together with its central electronics module integrates cameras (cable, seafloor and corer views), CTD (SBE37IDO), altimeter, 120KHz scientific echo-sounders, Niskin bottles and hydrocarbon sensor suite. Sensor data is delivered in real time to the surface via fibre optic deployment cable. Video data from the ICP cameras includes imagery of seafloor types and mid-water biota during the up/down casts, refer to related marlin record for video data access. This metadata record describes the sediment collection using the grab and ICP taken inside the Huon Commonwealth Marine Reserve at 5 depth strata (100m, 200m, 500m, 1000m and 2000m) and on Patience seamount. Sediment samples were collected for chemical (CSIRO Energy), grainsize and composition (SARDI) analyses; surface water was also collected for PAH (polycyclic aromatic hydrocarbons ) analysis by NMI (National Measurements Institute). Bulk samples of sediments were elutriated for macrofauna analysis (University of Adelaide).

    This dataset describes data collected from the Huon Estuary (Tasmania). Data was collected over a four day period during August/September 1998. Data was collected from 14 sites, ranging from 0 salinity at Judbury to a salinity of 35 at the seaward end of the estuary near Huon Island. Sites were selected to as possible sources of contaminants. Most sites were a subset from the Huon Estuary Study spatial surveys (refer to separate metadata record). Water samples were collected during the first three days. These samples were collected for salinity, dissolved oxygen, nutrients, trace metals, pesticides, pigments, spectral absorbance and phytoplankton. Sediment samples were collected during the last day. These samples were collected for organic tracers, pesticides, mercury and phytoplankton cysts. (Refer to the SED1 metadata record for more sediment information from the Huon Project.) This dataset forms part of the CSIRO Marine Research Huon Estuary study, conducted over the period 1996-1998.
