Temperature - Salinity distributions / CTD data within Jervis Bay and out across the shelf: 1991

This dataset is a component of the 'Jervis Bay Baseline Studies' project conducted by the Department of Defence, CSIRO and the Australian Defence Force Academy. 
Approximately once per month between 1988-1991, temperature-salinity surveys were conducted within Jervis Bay and out across the continental shelf. Measurements were made using a Neil Brown 'Smart' CTD. On each day of sampling, ~6 stations were chosen across the shelf, with the CTD recorder measuring salinity, temperature and sigma-T through the water column.
This record describes CTD data collected in 1991. For each day of sampling three resources are provided in the compressed (zipped) folder: 1) A map showing the location of each sampling station, 2) A word document providing vertically averaged CTD data over depth bins of 4m, and 3) An excel file providing the raw CTD data collected, as well as coordinates of the stations.
This is one of nine child records that relate to the parent, 13391430-2ae8-11dd-a735-00188b4c0af8. A pdf outlining the structure and hierarchy of all metadata records relating to this project is available to download through this record. Also available is a pdf of a published working paper documenting this experiment and the results.

Total 234Th and 238U data in East Antarctic polynyas

Thorium-234 samples were collected to determine the particulate organic carbon (POC) export fluxes in two East Antarctica polynyas, Dalton and Mertz. The samples were collected along the water column using the CTD deployed at several stations. The seawater Th-234 data was used in combination with POC:234Th ratios obtained from particulate samples collected using in situ pumps in order to derive the POC fluxes.
This record describes Th-234 and U-238_data: sample ID, depth, CTD file, station ID, latitude and longitude, Th-234 concentration and its uncertainty, U-238 concentration and its uncertainty.

Seaglider : a platform of the IMOS Ocean Gliders facility

The Ocean Gliders Facility (formerly known as the Australian National Facility for Ocean Gliders (ANFOG)), manages Sea gliders to monitor the boundary currents surroundings Australia.
Seagliders are autonomous underwater vehicles (AUV) which harvest their propulsion from the ocean itself. By changing its buoyancy via an inflatable oil-filled bladder, the Seaglider is able to descend and ascend. This momentum is converted to forward motion by its wings. Pitch adjustments are made by moving an internal mass (battery pack) forward or backward, and steering is done by rolling the battery packs. Moving at an average horizontal velocity of 25 - 40 cm s-1, the glider navigates its way to a series of waypoints using GPS, internal dead reckoning and altimeter measurements. Because the gliders are programmed to provide data and vehicle technical parameters through satellite communication when it is at the surface and glider pilots at the Ocean Gliders facility control centre (at the University of Western Australia) can continuously trim the Seaglider for optimal flight, change the voyage route, and examine the scientific data during the mission.
Sea gliders, built at the University of Washington, are designed to operate most efficiently in the open ocean up to 1000m water depth. Sea gliders have a maximum endurance time of up to 6 months and are used to gather long term environmental records.
Sea gliders are equipped with a Seabird CTD (SBE 41), WETLabs ECO Triplet (measuring chlorophyll-a, CDOM and 660nm Backscatter) and a Seabird oxygen sensor (SBE 43).

Distribution and abundance of herbivorous grazing fishes in the central Great Barrier Reef

A census of herbivorous grazing fishes was undertaken on 9 reefs located across the continental shelf in the central region of the Great Barrier Reef between July 1982 and February 1983. The reefs chosen for surveys were: 3 inshore reefs (Pandora Reef, Phillips Reef and Lorne Reef); 3 mid-shelf reefs (Rib Reef, John Brewer Reef and Lodestone Reef); and 3 outer shelf reefs (Myrmidon Reef, Dip Reef and Bowl Reef). For the mid- and outer shelf reefs, surveys were conducted within each of five reef zones: the windward reef slope, the windward reef crest, the reef flat, the lagoon and the back reef. The inshore reefs lacked distinct patterns of zonation and the perimeters of each reef were censused and treated as a single zone. The census was restricted to a list of 51 species from four families: Acanthuridae (24 species), Zanclidae (1 species), Scaridae (20 species) and Siganidae (6 species). Each species was also assigned to a feeding guild.A visual census technique was used for surveys and abundance was recorded using a log 3 abundance scale from 1 to 7. Each census dive through a zone was 30 minutes long and a distance of between 300 m and 400 m was covered, depending on conditions. Individuals within approximately 5 m either side of the diver were recorded. Juveniles (&lt;5 to 8 cm total length, depending on species) were not counted. For each species, abundance was recorded cumulatively throughout the census and all species were censused simultaneously. Census dives for the reef slope, reef crest and reef flat were unidirectional and parallel to the reef crest, while those for the lagoons and back reefs followed a meandering path. Four replicate, non-overlapping censuses were made once in each zone.
 This research was undertaken to investigate the variability in assemblages of herbivorous grazing fishes between zones within reefs, between reefs at similar locations on the continental shelf and between reefs at different locations across the continental shelf in the central region of the Great Barrier Reef.

Phytolith recovery from core MD88-779

Core MD88-779 was taken during the 1988 French APSARA IV cruise in the South East Indian Ocean. The core was situated on the South Tasman Rise (47º50.690S, 146º32.750E) at a depth of 2260m. Although the core recovered was 6.7m long, only the top 2.6m were studied as preliminary investigations had indicated that this section covered the last two glacial cycles.
Analysis of the sediment identified phytoliths in the core material. This is significant as this was the first known report of phytoliths in core material this south of Australia. Phytolith material was observed sporadically down-core at the following levels; 0, 130, 140, 220 and 230 cm (approximately falling within the Holocene, 100-110 ka, and 170 ka respectively). The phytolith casts most readily identifiable were those comprising the grasses, although larger plate-like casts of trees and shrubs were observed.

Northern Territory - National Intertidal-Subtidal Benthic NISB Habitat Map (PLUS)

The NISB Habitat Map was created by the University of Tasmania for a partnership between the Department of Climate Change and the National Land and Water Resources Audit. It supports the DCC/Audit partnership by providing a nationally consistent set of the available mapping data for those habitats that occur between the approximate position of the highest astronomical tide mark (HAT) and the location of the outer limit of the photic benthic zone (approximately at the 50-70 m depth contour). This area is broadly equivalent to the 'inner' and 'mid-shelf' regions identified by Geoscience Australia. The resulting map data set forms a core component of the ECM National Habitat Map Series. The habitat classes include: coral reef, rock dominated habitat, sediment dominated habitat, mangroves, saltmarsh, seagrass, macroalgae and filter feeders (e.g. sponges), as defined in the NISB Habitat Classification Scheme. The scheme is designed to support the development of marine 'ecoregions' or bioregional subregions. Details of the scheme and the process of its development are available in National Intertidal/Subtidal Benthic (NISB) Habitat Classification Scheme Version 1 (Mount, Bricher and Newton, 2007). The NISB Habitat Map consists of two layers for each state. _NISB.shp consists of the entire available habitat mapping at a resolution finer than 1:50 000 (with a few exceptions, outlined in the data quality section below). _NISB_PLUS.shp consists of all the data in _NISB.shp along with coarser resolution data, including NVIS and OzEstuaries data. These layers were used to produce the National ECM Key Habitat Distribution Map Series 10 km and 50 km tile maps.
Note: This data is labelled as “NISB_plus”, indicating that it is the NISB Habitat layer plus other lower quality layers.
