Sonde data measured during a high rainfall event in Port Jackson, 25 August 2007.

The Sydney Harbour catchment area includes a number of different river systems which drain into the Port Jackson estuary. During high rainfall events the catchment areas behave differently to deliver contaminants into the Port Jackson estuary. Under conditions of high rainfall contaminants are delivered to areas very quickly as freshwater slides over the top of the denser more saline waters of the estuary. Sonde samples, for measurement of conductivity, salinity, turbidity and temperature; were taken along the Port Jackson estuary over three days to determine the behaviour of the freshwater plume as it travels in a layer of freshwater to be flushed or flocculate out at some point in the estuary.

IMOS - Autonomous Underwater Vehicles - SIRIUS, CAMPAIGN: GREAT BARRIER REEF, FEBRUARY 2011

GBR Queensland (Doherty): In the Great Barrier Reef the program is focused on seagrass beds in the middle of the GBR lagoon to understand how their abundance is affected by upwelling coming through the Magnetic and Palm Passages and on deepwater coral reefs on the outer GBR.  Although there is extensive monitoring of shallow water reefs along the extent of the GBR, there has been relatively little opportunity to monitor deeper reefs. Understanding the nature of these deepwater reefs may provide important insights into the resilience of the GBR to stresses such as changing temperatures, ocean acidification, cyclones and nutrient influx from the coast.  Surveys of the seagrass beds in the lagoon, which were designed to revisit sites surveyed using towed video ten years ago, and at Myrmidon Reef on the outer GBR were completed during July 2011 to establish benthic reference sites in this area.

RAN CTD Profile Data - HMAS LEEUWIN ProjectID: HI460(A)LEE_H From: 2009-09-03 To: 2009-09-10

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 11 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI460(A)LEE_H from HMAS LEEUWIN. 
The CTD was manufactured by Falmouth Scientific and is the "2-inch Micro CTD" model. This CTD type is referred to operationally as the HS_CTD. This CTD is fitted within an inductive type conductivity cell, a platinum thermometer and silicon pressure sensor.
The CTD temperature sensor is calibrated on the ITS-90 temperature scale against a master CTD using a controlled temperature bath. The pressure sensor is calibrated using a Druck Pressure Calibrator. The conductivity sensor is calibrated in a temperature controlled bath against seawater samples of known conductivity.
The HS_CTD is lowered and raised by a hand winch sampling at a rate of 1.83 Hz. Data files were recorded in the downcast and upcast direction but most data is from downcasts due to higher quality. Raw CTD pressure data is not always monotonic due to transient up/down motion of winch/ship. Raw pressure data is subsetted to give a monotonic (increasing) sequence and then linearly interpolated to 1 decibar pressure intervals and converted to netCDF format files. Data is then flagged with quality control flags after visual inspection and comparison to average climatology and historical CTD casts.

Holothuria and trochus surveys of Ashmore, Cartier and Mermaid Reefs, north-western Australia

Surveys of holothurians and Trochus were conducted at Ashmore, Cartier and Mermaid Reefs to assess the impact of Indonesian fishing pressure on the natural stocks of these organisms. The project began in October 2000 with the initial survey of Ashmore Reef. Cartier Reef was then surveyed in November 2001. Both Cartier and Ashmore Reefs were resurveyed in May 2003. Mermaid Reef was surveyed in June 2003 to provide some control reference for relatively undisturbed populations of Trochus and Holothuria.

2016 Aerial survey data of southern right whales (Eubalaena australis) off southern Australia

These aerial survey data of southern right whales (Eubalaena australis) off southern Australia were collected in August 2016. Such annual flights in winter/spring between Cape Leeuwin (Western Australia) and Ceduna (South Australia) have now been conducted over a 23-year period 1993-2016. These surveys have provided evidence of a population trend of around 6% per year, and a current (at 2014) population size of approximately 2300 of what has been regarded as the 'western' Australian right whale subpopulation. With estimated population size in the low thousands, it is presumed to be still well below carrying capacity. No trend information is available for the 'eastern' subpopulation of animals occurring around the remainder of the southern Australian Coast, to at least as far as Sydney, New South Wales and the populations size is relatively small, probably in the low hundreds. A lower than  expected 'western' count in 2015 gives weak evidence that the growth rate may be starting to show signs of  slowing, though an exponential increase remains the best description of the data. If the low 2015 count is anomalous, future counts may be expected to show an exponential increase, but if it is not, modelling growth as other than simple exponential may be useful to explore in future.
A data update was provided in August, 2020 to correct some incorrectly given longitude values.

Redmap (Western Australia) - Sightings of Reptilian Species

Redmap is a primarily a website that invites the community to spot, log and map marine species that are uncommon in their region, or along particular parts of their coast. The information collected is mapped and displayed on the site, demonstrating, in time, how species distributions may be changing.
Sightings are divided into two categories – those with a photo that can be ‘verified’ by a marine biologist, and sightings without photos that we call community sightings (anecdotal). All the information collected, with and without photos, is mapped and will be used in the following years to map out a ‘story’ of changes occurring in our marine environment.
The main data collected includes the species sighted (normally selected from a list comprising preselected species of interest), the location, date/time and activity being undertaken.  Other optional information gathered include biological data such as sex, size and weight and environmental data such as water depth and temperature and habitat.
This record is associated with live data (and will subsequently change over time) and spatial elements have reduced accuracy.  It is also subject to a three year embargo (ie. does not contain data less than three years old).  If you wish to discuss obtaining a citable, static dataset, that is current and/or contains accurate spatial elements, please see Point of Contact.

Dispersion and Fates of Produced Formation Water Constituents in a Northwest Shelf Shallow Water Ecosystem and Bass Strait

This was a study of produced formation water (PFW) discharged into a shallow tropical marine ecosystem on the Northwest Shelf of Australia. A combination of oceanographic techniques, geochemical tracer studies, chemical and biological assessment methods, and dispersion modelling was used to describe the distribution and fate of petoleum hydrocarbons and added nutrients discharged from an offshore production platform. Using fine scale volatile hydrocarbon data, the horizontal and vertical diffusion parameters for a three dimensional dispersion model were calibrated under local conditions. Trace hydrocarbon chemistry studies and integration of the data into a mass balance model, facilitated a comprehensive description of dispersoin and degradation pathways and rates. Bioaccumulation into bivalves and water column microbial growth inhibition studies confirmed the chemistry and model predictions that the area of potential biological impact extended to 0.5 nautical mile (~900 m) from the discharge with additional skewing in the direction of the predominant tidal flows. Impact would be expected to be concentrated in transient surface slicks and near surface seawater. Dispersion and degradation processes were fast enough to prevent any long term accumulation of contamination within the system. Trace levels of oil in the near field sandy sediments were directly related to the magnitude of the daily discharge. The study is a bench-mark to help predict the effects of further oil industry expansion in this pristine coastal region.

South Australia - 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.

IMOS - Deep Water Moorings - Deep Water Arrays (DA) Sub-facility, East Australian deep water array, East Australian Current 5 Mooring (EAC5) Platform

The EAC5 deep water mooring was deployed in April 2012 at (-27.1 S, 155.3 E) off the Queensland coast, near Brisbane, Australia. The mooring was recovered in August 2013 and the array decommissioned, and a newly configured array (with new moorings) was redeployed in May 2015, and then subsequently decommissioned in July 2022.  
Instrumentation on the mooring includes Seabird SBE37SMPs, temperature loggers (Star Oddi, Starmon Mini) and discrete current meters (Aquadopp 6000).
The mooring will collect a time series of full-depth profiles of water velocity and discrete temperature and salinity measurements. 
The array will consist of 9 current meter and property moorings extending eastward from the Queensland Coastal Node shelf mooring array near Brisbane to the deep ocean. The moorings will be at 500-600 m intervals across the Continental Slope and increasing to 800-1000 m in the deep ocean.  
The East Australian Current (EAC) is the major western boundary current of the south Pacific Ocean. It plays a critical role in the ocean re-distribution of global heat from the equator to the midand- high latitudes. The EAC is relatively stable north of Brisbane, but as the current moves south 2-3 large eddies are pinched off every year. These eddies frequently move onto the continental shelf and close inshore and influence the local circulation patterns. At prominent coastal features the EAC moves away from the coast, driving upwelling which draws nutrient-rich water from a depth of 200-m or more.
