Opal concentrations measured in sediment samples collected during the IN2017-V01 voyage of the RV Investigator

Sediment cores were collected from the East Antarctic margin, aboard the Australian Marine National Facility R/V Investigator from January 14th to March 5th 2017 (IN2017_V01; (Armand et al., 2018). This marine geoscience expedition, named the “Sabrina Sea Floor Survey”, focused notably on studying the interactions of the Totten Glacier with the Southern Ocean through multiple glacial cycles. The cores were collected using a multi-corer (MC), were sliced every centimetre, wrapped up in plastic bags, and stored in the fridge. 
Sediment samples were dried in an oven at 40°C and ground using a pestle and a mortar. Biogenic silica (or ‘opal’) analysis was carried out following modification of the protocol of Mortlock and Froelich (1989). About 30 mg of sediment was leached with 30 mL of 1M sodium carbonate (Na2CO3) for 5 hours at 80°C. Every hour, 1 mL of sample was removed and centrifuged at 10,000 rpm for 30 sec. A 200 µL aliquot was removed from the supernatant and diluted 50x with Milli-Q water for SiO2 determination by molybdate-blue spectrophotometry. A standard calibration was prepared by dilution of a SiO2 standard solution (sodium hexafluorosilicate, from 0 to 200 µM). The opal concentrations were calculated using the slope of the last three points of the dissolution curve (Demaster, 1981), or the changing slope part of the curve.

Aurora Australis Voyage 3 2012/13 Track and Underway Data

On every voyage of the Aurora Australis, approximately 50 onboard sensors collect data on average every 10 seconds.  These data are known as the underway datasets.  The type of data collected include water and air temperature, wind speeds, ship speed and location, humidity, fluorescence, salinity and so on.  For the full list of available data types, see the website.
These data are broadcast "live" (every 30 minutes) back to Australia and are available via the Australian Oceanographic Data Centre's portal (see the provided link).  Once the ship returns to port, the data are then transferred to Australian Antarctic Division servers where they are then made available via the Marine Science Data Search system (see the provided URL).
This dataset contains the underway data collected during Voyage 3 of the Aurora Australis Voyage in the 2012/13 season.
Purpose of voyage: Mawson Station resupply
Underway (meteorological) data are available online via the Australian Antarctic Division Data Centre web page (or via the Related URL section).

Seabird strikes at Australian Antarctic Stations and on ships.

This indicator is no longer maintained, and is considered OBSOLETE.
INDICATOR DEFINITION
All known observations of seabird strikes are recorded upon observation at Australian Antarctic Stations and on ships travelling in the Southern Ocean.
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: PRESSURE
RATIONALE FOR INDICATOR SELECTION
Human presence in the Antarctic has led to the creation of many stations located around the continent. In many cases, these stations are sited close to seabird colonies. Birds have struck station buildings, radio masts, etc. Further, seabird strikes are reported from resupply and research vessels. In recent decades, there have been observations made of bird strikes, particularly colliding with station infrastructure, remote installations and supporting infrastructure and ship-based transport to the continent. Whilst the data are not considered to be comprehensive or highly rigorous, it is envisaged that recording of bird strikes may facilitate useful analysis in the future.
DESIGN AND STRATEGY FOR INDICATOR MONITORING PROGRAM
Spatial scale: Southern Ocean: 40S to the Antarctic continent, Mawson, Davis, Casey, Macquarie Island, Heard Island, field camps, and summer expeditions.
Frequency: Annual.
Measurement technique: Observation of bird strikes at Australian Antarctic Stations and at sea.
RESEARCH ISSUES
The accuracy of the data are likely to be limited as it depends upon the detection of bird strikes by actual observation of the strike as it occurs, or the discovery of bird carcasses near the structure with which it collided.

Physiological Tolerances of Some Antarctic Zooplanktons

Colonisation of Lake Fletcher, a hypersaline, meromictic lake in the Vestfold Hills, Antarctica, by the calanoid copepod Drepanopus bispinosus, the cyclopoid copepod Oncea curvata and an undescribed cydippid ctenophore is discussed.  In 1978, salinity direstly under the ice was 66 ppt and repeated net hauls found no zooplankton.  In 1983, adults of D. bispinosus were found, and in 1984, a reproductively active population of this species.  Surface water salinity in 1984 was 56 ppt. During winter 1986, surface salinity was 54 ppt and three zooplankton species (D. bispinosus, O curvata and an undescribed cydippid ctenophore) had established populations in the lake.  In 1986/87, high tides caused nearby Taynaya Bay to flood into the lake, and three further species (the calanoid, Paralabidocera antarctica, and two harpacticoids, Harpacticus furcatus and Idomene sp.) were found in the lake. It appears that periodic flooding after 1978 caused a salinity decrease in the lake from 66 to 54 ppt, and this enabled some invertebrate species to maintain year-round populations, whereas others require marine incursions to re-establish summer only populations.

Fluoride Concentration in Antarctic Marine Crustaceans

Metadata record for data from ASAC Project 587
See the link below for public details on this project.
From the abstracts of some of the referenced papers:
The concentration of fluoride in the body parts of a range of Antarctic crustaceans from a variety of habits was examined with the aim of determining whether fluoride concentration is related to lifestyle or phylogenetic grouping.  Euphausiids had the highest overall fluoride concentrations of a range of Antarctic marine crustaceans examined; levels of up to 5477 micro grams per gram were found in the exoskeleton of Euphausia crystallorophias. Copepods had the lowest fluoride levels (0.87 micrograms per gram) whole-body); some amphipods and mysids also exhibited relatively high fluoride levels.  There was no apparent relationship between the lifestyle of the crustaceans and their fluoride level; benthic and pelagic species exhibited both high and low  fluoride levels.  Fluoride was concentrated in the exoskeleton, but not evenly distributed through it; the exoskeleton of the head carapace and abdomen contained the highest concentrations of fluoride, followed by the feeding basket and pleopods, and the eyes.  The mouthparts of E. superba contained almost 13,000 microgams F per gram dry weight. Antarctic krill tail muscle had low levels of fluoride. After long-term (1 to 5 year) storage in formalin, fluoride was almost completely lost from whole euphausiids.
A series of experiments was carried out to determine the relationship between feeding, moulting, and fluoride content in Antarctic krill (Euphausia superba).  Starvation increased the intermoult period in krill, but had no effect on the fluoride concentrations of the moults produced.  Addition of excess fluoride to the sea water had no direct effect on the intermoult period, the moult weight, or moult size.  Additions of 6 micrograms per litre and 10 micrograms per litre fluoride raised the fluoride concentrations of the molts produced and of the whole animals.  The whole body fluoride content varied cyclically during the moult cycle, reaching a peak 6 days following ecdysis.  Fluoride loss at ecydsis could largely be explained by the amount of this ion shed in the moult.
This work was completed as part of ASAC projects 41 and 587 (ASAC_41, ASAC_587).

Further investigations of the effects of the Nella Dan oil spill

Metadata record for data expected from ASAC Project 1003
Further investigations of the effects of the Nella Dan oil spill on intertidal benthic communities at Macquarie Island: continued recovery of kelp holdfast communities.
See the link below for public details on this project.
The project investigated spatial variation in kelp holdfast macrofaunal communities 7 years after the initial oil spill.  The project was expanded to cover more sites than were sampled in projects 250 (ASAC_250) and 672 (ASAC_672).  Results indicated that an impact was still detectable at one of the 3 oiled sites.
This dataset contains the 1988 and 1994 data.  Holdfast data from the 1994/1995 season is also included (comparing east versus west).
The numbers are total individuals of each species that were found in each  holdfast sample.  This is a basic, though standard, species-abundance matrix.
The site codes used in this project are:
SB = Sandy Bay
SEC = Secluded Bay
BB = Buckles Bay
GC = Garden Cove
GG = Green Gorge
GB = Goat Bay
HMB = Half Moon Bay
BAUER = Bauer Bay
Other codes as for oil spill data
The first number given after the site code is the site number at that sampling location.  The second number is the replicate at that site.  Thus sb(1)3 is Sandy Bay site 1, replicate 3.
