SRE4 Metals in treatment Oils

Sediment Recruitment Experiment 4 (SRE4) was a large, long term (5 year) field experiment run at Casey Station (from 2001 to 2006) testing the effects of 4 different hydrocarbons on marine sediment ecosystems. Four different types of hydrocarbons were individually mixed with defaunated marine sediments and deployed in trays on the seabed at O'Brien Bay-1. Trays were collected after deployment periods of 5 weeks, 56 weeks, 62 weeks, 2 years and 5 years. In addition there was a bioturbation treatment using the burrowing urchin Abatus (at 56 weeks only). Samples were collected from 4 replicate trays of each treatment at each sampling time. Analyses were done of sediment hydrocarbon chemistry, microbial communities, meiofaunal communities, macrofaunal communities and diatom communities. The hydrocarbon treatments were: a synthetic Mobil lubricating oil; the same Mobil lubricating oil after 125? hours use in a vehicle engine; a Fuchs synthetic lubricating oil marketed as highly biodegradable; and Special Antarctic Blend diesel fuel (SAB). A control uncontaminated sediment treatment was used for comparison.

Seabird assemblages observed during the BROKE-West survey of the Antarctic coastline (30-80 E), January-March 2006

Seabird surveys in January - March 2006 of a poorly known area of the Southern Ocean adjacent to the East Antarctic coast identified six seabird communities, several of which were comparable to seabird communities identified both in adjacent sectors of the Antarctic, and elsewhere in the Southern Ocean. These results support previous proposals that the Southern Ocean seabird community is characterised by an ice-associated assemblage and an open-water assemblage, with the species composition of the assemblages reflecting local (Antarctic-resident) breeding species, and the migratory routes and feeding areas of distant-breeding taxa, respectively. Physical environmental covariates such as sea-ice cover, distance to continental shelf and time of year influenced the distribution and abundance of seabirds observed, but the roles of these factors in the observed spatial and temporal patterns in seabird assemblages was confounded by the duration of the survey. Occurrence of a number of seabird taxa exhibited significant correlations with krill densities at one or two spatial scales, but only three taxa (Arctic tern, snow petrel and dark shearwaters, i.e. sooty and short-tailed shearwaters) showed significant correlations at a range of spatial scales. Dark shearwater abundances showed correlations with krill densities across the range of spatial scales examined.
This work was conducted on the BROKE-West voyage of the Aurora Australis.

Aurora Australis Voyage 7.2 (HIMS) 1989-90 Heard Island Fish Data

This dataset contains the data from Voyage 7.2 (HIMS) 1989-90 of the Aurora Australis. There were three objectives of the fish program: To assess the distribution and abundance of demersal fish on the shelf in the AFZ around Heard Island; to investigate the biology of the more important species; to take samples to determine by mitochondrial DNA (mtDNA) analysis whether the Heard Island Champsocephalus gunnari are a genetically distinct stock from those around Kerguelen Islands. The observations were taken from around Heard Island between May and June 1990. The data contains temperature and salinity data from a CTD survey and the results from various trawl surveys. The major species were Dissostichus eleginoides, macrourus holotrachys, Champsocephalus gunnari and Notothenia squamifrons. Numbers, species identity, guts and gonad data were obtained. This is a subset of the data for the whole voyage.

Rates of depletion of lubricant and fuel contaminants from Antarctic regions during natural attenuation and remediation procedures - GC_MS lubrication oil data

These data relate to the Max Easton Honours project, carried out at Macquarie University in 2010, supervised by Simon George THE LONG-TERM DEGRADATION OF LUBRICANT OIL IN ANTARCTIC MARINE SEDIMENTS.
A simulated marine spill has been carried out by the Australian Antarctic Division (AAD) over a five year period, in which Antarctic sea-bed sediments were doped with various petroleum products and left in a shallow marine environment to examine the extent and rate of natural degradation. Of these pollutants, unused Mobil lubricant oil (OW/40; Exxon Mobil) was analysed qualitatively and semi-quantitatively by gas chromatography-mass spectroscopy (GC-MS) to determine the composition of the oil and the rates and modes of degradation.
The Mobil Lubricant Oil was found to consist of three dominant compound classes; 
1) a series of branched alkanes with chain lengths of C25-26 and C33-34,
2) a series of long chain alkylnaphthalenes (formula C26H40), and
3) a series of bulky alkanoate esters.
Other minor compounds were also identified. The alkanoate esters were depleted most readily, to less than 20% their initial values after 65 weeks. Branched alkanes and long chain alkylnaphthalenes were both recalcitrant over time, present at ~10% of their initial value after 260 weeks. Both the branched alkanes and long chain alkylnaphthalenes exhibited near identical behaviour through the sediment profile over time, depleting at the surface and increasing at depths consistent with migration through the sediment profile. Branched alkanes were depleted most rapidly relative to all other compounds, perhaps owing to preferred the biodegradation of long alkyl chains.
No clear interpretation of the dominant mode of degradation was able to be defined, although it is believed that a multitude of removal mechanisms participate in the removal of lubricant oils in Antarctic marine sediments.
1) Retention time - Minutes
2) Region - It is a retention time window, labelled A to G as colours
3) Peak area - Peak area is in arbitrary units.

Particulate carbon export flux layers

These POC export flux maps (units of g C. m-2 day-1) were compiled from Lutz et al. (2007) algorithm, following Woolley et al. (2016) procedure. They were produced after calculation of the Seasonal Variation Index of Net Primary Production layers (NPP, g C. m-2 day-1, see Lutz et al. 2007 for the methodology) available on a monthly basis at http://www.science.oregonstate.edu/ocean.productivity/custom.php (accessed on April 05, 2017). NPP layers are derivates of  the Carbon-based Productivity Model that integrates several compounds such as satellite data color measurements, photosynthetically active radiation values or mix layer and nitrocline depth estimations (Westberry et al. 2008). Bathymetric layers used for the calculation were derived from Fabry-Ruiz et al. (submitted paper).

Soft sediment assemblages at Casey Station: (core samples: Nov 1998 - Jan 1999)

A survey of macrobenthic assemblages in soft-sediments was done at Casey Station, East Antarctica. Samples were taken by divers using hand-held corers (core size - 10 cm diameter by 10 cm deep). This was the final component of a large nested sampling survey extending over a three year periods with samples taken in three summers and one winter period.
The aims were: 1) To examine spatial variation at several scales in these assemblages; 2) To determine if there were differences between potentially impacted areas and control areas; 3) To determine the level of replication, taxonomic resolution and data transformation that are appropriate to studies of human impacts in Antarctic soft-sediment assemblages. Cores were collected by divers in a hierarchical, spatially nested design incorporating 4 scales: Locations (1000s of metres apart), Sites (100s of metres), Plots (10s of metres) and among replicates within plots (~1 metre). This data set consists of 48 core samples from three locations, O'Brien Bay, Sparkes Bay and Wilkes. Samples are sorted mainly to species.

Acoustic Sounder Charts from Australian Antarctic Division Voyage 6 1994/95 (BANGSS)

Acoustic sounder charts were collected at six locations during Australian Antarctic Division Voyage 6 1994/95 (BANGSS) using the Kongsberg EA200 Echo Sounder on the Aurora Australis. 
BANGSS is an acronym for Big ANtarctic Geological and Seismic Survey.
The voyage began on 6 February 1995 and finished on 12 April 1995.
Each chart is labelled with information about when and where the data was collected: date, time, latitude and longitude.
The charts provide a profile of the sea floor and have a time axis with numbers in the following format.
the first two digits are the day
the next two digits are the month
the next five digits are the time (UTC)
the last ten digits are the maximum value on the depth axis 
eg 2402005 360000000500 means 24 February 5:36 UTC and the maximum value on the depth axis is 500 metres 
See a Related URL for a link to information about the voyage including the voyage report.

Adelie penguin occupancy survey of the Svenner Islands, 2010

Occupancy surveys in November 2009 and December 2010 (Southwell and Emmerson 2013) found a total of 15 Adelie penguin breeding sites in the Svenner Islands between longitudes 76.50oE to 77.50oE. The boundaries of breeding sub-colonies were subsequently mapped from vertical aerial photographs taken for abundance surveys on 20 November 2010 (for details of aerial photography see Southwell et al. 2013). The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies. When photos of Island 73036 were viewed there was no colony to map so only 14 islands were mapped.

Passive acoustic data from sonobuoys deployed during the 2013 Antarctic Blue Whale Voyage

This dataset contains acoustic recordings from Directional Frequency Analysis and Recording (DIFAR) sonobuoys that were deployed during the 2013 Antarctic blue whale voyage.  During the 47 day voyage 360 sonobuoys were deployed yielding 733 hours of acoustic recordings. On average, slightly more than eight sonobuoys were used per survey day. Ninety three sonobuoys were deployed in transit to or from the edge of the sea-ice while the remainder were deployed to monitor and target Antarctic blue whales. The telemetered audio from sonobuoys was monitored aurally and visually (via spectrogram) in real-time by one or more on-duty acousticians. A total team of five dedicated acousticians monitored round-the-clock for blue whales and in all weather conditions. Upon detection of blue whale vocalisations the vessel was directed towards the locations of these sounds.
After deployment, sonobuoys sent acoustic and directional data to the ship via a VHF radio transmitter. Radio signals from the sonobuoy were received using an omnidirectional VHF antenna (PCTel Inc. MFB1443; 3 dB gain tuned to 144 MHz centre frequency) and pre-amplifier (Minicircuits Inc. ZX60-33LN-S+) mounted on the mast of the ship at a height of 21 m. The preamplifier was connected to a power splitter via LMR400 cable and signals were received with two WiNRaDiO G39WSBe sonobuoy receivers. The radio signal from sonobuoys was adequate for monitoring and localization out to a typical range of 12-15 nmi. Received signals were digitised via a sound board (RME Fireface; RME Inc.), and signals were recorded on a personal computer using the software program PAMGuard (Gillespie et al. 2008). Three models of sonobuoys were used during the voyage: 79 were AN/SSQ-53D (Ultra Electronics, Canada), 81 were AN/SSQ-53F (Ultra Electronics: SonobuoyTechSystems, USA) and 200 were AN/SSQ-955-HIDAR (deployed in DIFAR compatibility mode; Ultra Electronics Sonar Systems, UK).
In addition to recording of Antarctic blue whale song, New Zealand type blue whale song, and blue whale "D-call" vocalisations, these recordings also contain vocalisations from fin whales, humpback whales, sei whales, killer whales, sperm whales, as well as low frequency sounds from Antarctic  sea ice.
