Ice core meiofauna during the SIPEX and SIPEX II voyages

Zooplankton were collected during the winter-spring  transition during two cruises of the Aurora Australis: SIPEX in 2007 and SIPEX II in 2012. As part of the collections sea ice cores were collected to describe the ice habitat during the period of zooplankton collections. Ice cores were taken with a 20 cm diameter SIPRE corer and sectioned in the field with an ice core. Temperature was measured in the section using a spike thermometer and slivers of each section were melted without filtered water to record salinity. The remainders of each section were melted at 4oC in filtered seawater and the melted water was used to measure chlorophyll a concentration, and meiofauna species and abundance. Meiofauna were counted and identified using a Leica M12 microscope: to species in most cases and down to stage during 2012.

Illuminating the Biodiversity of the Cape Range and Cloates Canyons

Survey FK200308 on the R/V Falkor undertook detailed mapping within two significant and biologically unexplored submarine canyons (Cape Range and Cloates Canyon) in the Gascoyne Marine Park. The Gascoyne Marine Park covers 81, 766 km2 adjacent to the Ningaloo Marine Park. The canyons form part of the habitat protection and multiple use zones of the marine park and are identified as Key Ecological Features. The canyons provide an important connection between the abyssal plain environments and the Commonwealth waters adjacent to Ningaloo Reef on the continental shelf. High productivity aided by upwelling through the canyons has been related to aggregations of whale sharks, manta rays, humpback whales, sea snakes, sharks, large predatory fish and seabirds. In addition, the hard canyon walls provide habitat for a range of sessile invertebrates, while the soft sediments on the canyon floor support a range of mobile invertebrates. The data from this survey will provide a comprehensive taxonomic survey to characterise the marine biodiversity of the canyons or to understand the distribution of canyon habitats in relation to the seabed morphology.
Bathymetry and acoustic reflectance (backscatter) data were acquired in the survey region using a Kongsberg 30 kHz EM 302 deep water multi-beam echo sounder with a 1° array. An area of 11,250 km2 was surveyed along 4100 line kilometres within the Gascoyne Marine Park. In addition, 2495 line kilometres was surveyed along transits between Fremantle, Exmouth and Broome. Navigation and motion were recorded with an Applanix POSMV V5, while sound speed profiles were processed with the software Sound Speed Manager to correct acoustic data.

Nella Dan: ADBEX II Cruise - Hydroacoustic krill survey data

This dataset contains hydroacoustic results from the Antarctic Division Biomass Experiment II (ADBEX II) cruise of the Nella Dan. This cruise is the third in a series of six cruises, performing a long term survey of krill and other zooplankton distribution and abundance.
Australia was to have participated in the Second International Biomass Experiment I (SIBEX I), but withdrew due to resupply problems.  ADBEX II is a reduced sampling program of what was to have been sampled during SIBEX I. Three transects were made off Antarctica in the Mawson region of the Australian sector, in January to March 1984, covering a survey area of 70,000 square kilometers. Quantitative and geographic krill distribution, abundance, mean and variance of the krill weight density, and total krill biomass were obtained. Biomass estimates for ADBEX II are given as 3.5 million tonnes, obtained by extrapolating over the survey area used on the SIBEX II cruise (1.28x10^6 square kilometers). Temperature, nutrient and salinty data were also obtained, as well as trawl results. Summary results are listed in the documentation.

Average sea surface temperatures in latitude bands: 40-50 deg S, 50-60 deg S, 60 deg S-continent

This indicator is no longer maintained, and is considered OBSOLETE.
INDICATOR DEFINITION
Measurements of sea surface temperature in the Southern Ocean. Measurements are averaged over latitude bands: 40-50 deg S, 50-60 deg S, 60 deg S-continent.
TYPE OF INDICATOR
There are three types of indicators used in this report:
1.Describes the CONDITION of important elements of a system;
2.Show the extent of the major PRESSURES exerted on a system;
3.Determine RESPONSES to either condition or changes in the condition of a system.
This indicator is one of: CONDITION
RATIONALE FOR INDICATOR SELECTION
Australian and Antarctic climate and marine living resources are sensitive to the distribution of ocean temperature.  Sea surface values are relatively easy to monitor, and therefore can be used as a relevant indicator of the state of the ocean environment.
The information provided by long records of sea surface temperature is needed to detect changes in the Southern Ocean resulting from climate change; to test climate model predictions; to develop an understanding of links between the Ocean and climate variability in Australia; and for sustainable development of marine resources.
DESIGN AND STRATEGY FOR INDICATOR MONITORING PROGRAM
Spatial scale: Southern Ocean: 40 deg S to the Antarctic continent
Frequency: Monthly averages over summer
Measurement technique: Measurements of sea surface temperature from Antarctic supply ships. The best spatial coverage of sea surface temperature is provided by satellites, due to extensive cloud cover in the Southern Ocean and biases in the satellite measurement, in situ observations of sea surface temperature are necessary.
RESEARCH ISSUES
Sea surface temperature has not been previously used as a spatially averaged environmental indicator.  Some experimentation with past data are required to define the most appropriate averaging strategy.
New technologies like profiling Argo floats need to be exploited to provide better spatial and temporal coverage of temperature in the Southern Ocean.

2010/11 VMS Geonomics sampling - data collected from the VMS (Voyage Marine Science) voyage of the Aurora Australis

Purpose of future metagenomic (DNA), metaproteomic (protein) and metatranscriptomic (RNA) analysis:
For each sample, two drums (~200L each) of seawater were collected. Samples were taken from CTD sites, and surface samples (2m depth) taken at each of these sites. At most of these CTD sites, a deeper sample was taken according to the location of the DCM at that site. The 200L seawater is pumped through a 20 micron mesh to remove the largest particles, then the biomass is collected on three consecutive filters corresponding to decreasing pore size (3.0 microns, 0.8 microns, 0.1 microns). This is repeated for each sample using the second 200L of seawater to generate duplicates for each sample. The overall aim is to determine the identity of microbes present in the Southern Ocean, and what microbial metabolic processes are in operation. In other words: who is there, and what they are doing. Special emphasis was placed on the SR3 transect.
Samples were collected as below. For each sample, a total of six filters were obtained (3x pore sizes, 2x replicates). Each filter is stored in a storage buffer in a 50mL tube, and placed at -80 degrees C for the remainder of the voyage.

Hydroacoustic data collected onboard the Aurora Australis during voyage 3 of the 2005-2006 season (BROKE-West)

This dataset contains data files, processing templates and documentation relating to the BROKE-West multifrequency echosounder (acoustic) survey carried out from the RSV Aurora Australis in the austral summer of 2005/06 (ASAC project 2655). The primary aim of the acoustic survey was to describe the distribution and abundance of Antarctic krill (Euphausia superba) in CCAMLR Division 58.4.2. However, these data are also relevant for studies of other sound-scattering targets detected by the echosounder system, for example other pelagic taxa or the seafloor. 
The dataset is a collection of .csv data files, .ev processing files and *.pdf documentation files, organised into 4 categories:

Acoustic survey: data files relating to the transects undertaken for the acoustic survey 2. Acoustic data processing: metadata files, processing templates and documentation relating to the collection and processing of the acoustic data 3. Acoustic results: results arising from the processing of the raw data. The raw data are described in a separate metadata record - "AAD Hydroacoustics hard disks - data collected from Southern Ocean cruises..." 4. Ancillary data: additional non-acoustic data used during the processing of the acoustic data

The file "data_fields.pdf" lists and describes the fields in each of the *.csv data files.
The file "processing_methods.pdf" provides a synopsis of the methods by which the raw acoustic data were collected and processed.
The BROKE-West survey was conducted on voyage 3 of the Aurora Australis during the 2005-3006 season. It was intended to be a comprehensive biological and oceanographic survey of the region between 30 degrees and 80 degrees east.
