Nella Dan: SIBEX II Cruise - Oceanographic and nutrient data

This dataset contains CTD (conductivity, temperature, depth) and nutrient (nitrate, nitrite (insignificant concentrations), phosphate, silicate) data obtained from the Second International BIOMASS Experiment (SIBEX II) cruise of the Nella Dan, during January 1985. This cruise is the fourth in a series of six cruises, conducting a long term field survey on krill and other zooplankton. 64 CTD casts were taken in the Prydz Bay region, and nutrient data were collected at 44 of the stations. Casts were made to 1000 m or to near bottom if shallower. Oceanographic and nutrient sampling was done a supplement to the krill research program, and therefore was not always ideal for oceanographic purposes.
The fields in this dataset are:
cruise name
station number
date
start time
ship name
station position

Copepod faecal pellets and carbon flux in the coastal sea-ice zone

This dataset contains samples collected at O'Gorman Rocks and Ellis Fjord near Davis station from December 1997 to March 1998. Depth-stratified zooplankton samples were obtained for determination of zooplankton abundance and biomass. Water samples were collected for the determination of chlorophyll a concentration, protist identification and abundance, and the concentration of particulate and dissolved organic carbon. Sediment trap material was collected for the analysis of faecal pellets (identification and CHN analyses), protist identification and abundance, and the measurement of particulate organic carbon concentration. Zooplankton grazing experiments were performed in the laboratory at Davis station and zooplankton were also collected for CHN analyses. Data from this project arose from projects ASAC 963 and ASAC 2229.

Cape Darnley Early-Autumn Phytoplankton Bloom, March 2012

These data relate to a large-scale early-autumn phytoplankton bloom that occurred off Cape Darnley, East Antarctica, in March 2012. The bloom was detected by Dr Jan Lieser (Antarctic Climate and Ecosystems Cooperative Research Centre, ACE-CRC) through MODIS satellite and was opportunistically sampled from RSV Aurora Australis using the uncontaminated seawater line. Samples were analysed for protist species and abundances using light and scanning electron microscopy, and pigment analyses were conducted using high performance liquid chromatography. Additional water samples were taken for dissolved nutrient analyses.  
Specific details of the files are:
Cape Darnley Protist Counts
Samples were preserved with 1 % vol:vol Lugols iodine and stored in glass bottles in the dark at 4 degrees C. Protists were identified and counted using phase and Nomarski interference optics using Olympus IX71 and IX81 inverted microscopes at 400X to 640X magnification. Bright field optics were also used to discriminate taxa that contained chloroplasts. Protistan taxa were counted in 20 randomly chosen fields of view, except for highly abundant taxa that were counted in a subset of the field of view defined by an ocular quadrant (Whipple grid). Cell biovolumes and carbon conversion statistics were used to calculate the cell biomass of protistan taxa/groups.
Cape Darnley Fluorometer Calibration
Fluorometer measurements from the ships underway system were calibrated using chlorophyll a readings determined through high performance liquid chromatography. A linear relationship was established between fluorometer v HPLC chlorophyll a measurements at the same sites. The linear equation was then used to convert all underway fluorometry data from the voyage.
Cape Darnley Bloom HPLC Pigments CHEMTAX summary
Major phytoplankton groups at each site determined through analysis of pigments using high performance liquid chromatography and CHEMTAX. Methods were according to that of Wright et al. (2010).
Cape Darnley Bloom Nutrients
Dissolved nutrient concentrations. Samples were analysed by the Department of Primary Industries, Parks, Water and Environment, 18 St. Johns Avenue, Newtown, Tasmania 7008.

Repetition patterns in Weddell seal (Leptonychotes weddellii) underwater multiple element calls

Many vocalisations produced by Weddell seals (Leptonychotes weddellii) are made up of repeated individual distinct sounds (elements).  Patterning of multiple element calls was examined during the breeding season at Casey and Davis, Antarctica.  Element and interval durations were measured from 405 calls all greater than 3 elements in length.  The duration of the calls (22 plus or minus 16.6s) did not seem to vary with an increasing number of elements (F4.404 = 1.83, p = 0.122) because element and interval durations decreased as the number of elements within a call increased.  Underwater vocalisations showed seven distinct timing patterns of increasing, decreasing, or constant element and interval durations throughout the calls.  One call type occurred with six rhythm patterns, although the majority exhibited only two rhythms.  Some call types also displayed steady frequency changes as they progressed.  Weddell seal multiple element calls are rhythmically repeated and thus the durations of the elements and intervals within a call occur in a regular manner. Rhythmical repetition used during vocal communication likely enhances the probability of a call being detected and has important implications for the extent to which the seals can successfully transmit information over long distances and during times of high level background noise.

Recruitment Tile Sessile Fauna data from the antFOCE (Antarctic Free Ocean Carbon Enrichment) experiment at Casey Station

Refer to antFOCE report section 4.5.1 for deployment, sampling and analysis details.
https://data.aad.gov.au/metadata/records/AAS_4127_antFOCE_Project4127
The download file contains an Excel workbook with one data spreadsheet and one of notes relevant to the data. The data are the total number of each sessile organism collected per tile as per the census methods detailed in the Notes spreadsheet. Tiles were deployed in chambers or open plots during the antFOCE experiment on a metal stand in either a horizontal or vertical orientation.   
Background 
The antFOCE experimental system was deployed in O’Brien Bay, approximately 5 kilometres south of Casey station, East Antarctica, in the austral summer of 2014/15. Surface and sub-surface (in water below the sea ice) infrastructure allowed controlled manipulation of seawater pH levels (reduced by 0.4 pH units below ambient) in 2 chambers placed on the sea floor over natural benthic communities. Two control chambers (no pH manipulation) and two open plots (no chambers, no pH manipulation) were also sampled to compare to the pH manipulated (acidified) treatment chambers.  
Details of the antFOCE experiment can be found in the report – “antFOCE 2014/15 – Experimental System, Deployment, Sampling and Analysis”. This report and a diagram indicating how the various antFOCE data sets relate to each other are available at:
