Seal database of known-age animals from the Antarctic and subantarctic Southern Ocean

This database is a compendium of histories of known age seals (Weddell and Southern elephant) from observations across the Southern Ocean but focussed on Macquarie Island, Marion Island, Heard Island, Mawson and the Vestfold Hills.
At Macquarie Island 1000 seals were weighed per annum between 1993-2003 at birth and individually marked with two plastic flipper tags in the inter-digital webbing of their hind flippers. These tagged seals were weighed again at weaning, when length, girth, fat depth, and flipper measurements were made. Three weeks after weaning 2000 seals were permanently and individually marked by hot-iron branding. Recaptures and re-weighings of these known aged individuals were used to calculate growth and age-specific survival of the seals.
Similar data were collected from elephant seals between 1950 and 1965 when seals were individually marked by hot-iron branding. Mark-recapture data from these cohorts were used to assess the demography of the declining population. Length and mass data were also collected for these cohorts and were used, for the first time, to assess the growth of individual seals without killing them.
At Marion Island all the elephant seals have been individually marked with two plastic flipper tags in their rear flippers. Recaptures of these seals were used to compare survival at Marion and Macquarie Islands.
At Heard Island, seals were branded between 1949-1953.  Seal length was measured in feet and inches.  Recaptures of seals were made up until 1955, and growth and age-specific survival was calculated.  Survival data from Heard Island were compared with concurrent data from Macquarie Island.
The database was held by the Australian Antarctic Data Centre, but was taken offline due to maintenance problems.  A snapshot of the database was taken in June 2018 and stored in an access database.
This work was completed as part of ASAC project 90.

TEMPO (Trends in Euphausiids off Mawson, Predators, and Oceanography) Phytoplankton Distribution and Abundance

This dataset describes phytoplankton distribution and abundance and abundance during the TEMPO Voyage (Trends in Euphausiids off Mawson, Predators, and Oceanography), conducted on RV Investigator from February to March 2021 (IN2021_V01, CSIRO Marine National Facility). The primary goal of TEMPO was to collect data to estimate krill biomass with a view to updating the precautionary catch limit within CCAMLR’s Division 58.4.2-East. It also aimed to increase our understanding of krill habitat to ensure sustainable management, with part focus on phytoplankton populations given they are the main food source for krill. Six north-south transects were conducted from west to east (55-80°E) with each extending from 62 or 63°S to the sea-ice edge. Some transects coincided with the eastern transects of a previous voyage undertaken in 2006 (BROKE-WEST, Nicol, Raymond and Meiners 2010), providing a valuable comparison.

Prawns (Chorismus antarcticus) caught by mesh traps at the Vestfold Hills

This record describes the collection of marine fauna sampled from coastal areas of the Vestfold Hills in 1999.  The project was undertaken to compile morphometric data on Weddell seal prey species. Benthic prawns i.e. Chorismus antarcticus and Notocrangon antarcticus, are common Weddell prey species at the Vestfold Hills. We fished for prawns using mesh traps (40 x 20 x 20 cm3). The traps were set at Magnetic Island in May, and in Ellis Fjord in December. The site near Magnetic Island was chosen when the fast-ice fractured enabling the gear to be set in natural tracts of open water. The site in Ellis Fjord was chosen on the basis of published information regarding bathymetry and the range of depths inhabited by prawn species. We waited until December to sample in Ellis Fjord so that the fishing hole did not refreeze.
Prawns were caught only in Ellis Fjord and only when the traps were deployed open i.e. with zips on the doors to get the catch out left undone. Approximately 50 prawns of various sizes were caught over three days at the same location, 200 m east of the crossing at Ellis Narrows. The catch has been stored whole in the Australian Antarctic Division freezer in Hobart. Bycatch included amphipods and Notothenid fish at Magnetic Island, and echinoderms, holothurians and Notothenid fish in Ellis Fjord. Some of the bycatch were retained and are stored frozen with the prawns.
The linked dataset contains the measurements of length, mass, carapace length and sex (juvenile, male, female) of the prawn catch. All of the prawns were Chorismus antarcticus. The adult females were brooding eggs. The best fit linear regressions were y = 0.3529x - 2.4824, (R2 = 0.9504) for carapace length to predict body mass, and y = 3.5267x + 4.5846 (R2 = 0.9544) for carapace length to body length. The associated URLs contain all of the data, including spreadsheet of data, a scatterplot of the length mass relationship, and a mass frequency histogram of the catch.

Particulate organic matter elemental analysis, mixed layer, during the K-Azis voyage of the Aurora Australis au1603

Water samples of 1 to 2L from Niskin bottles filled close to the surface, mid mixed layer depth and bottom of the mixed layer were drawn cleanly through a 210um mesh to exclude zooplankton. All samples were filtered as two size fractions, 1.2 to 20um (larger particles excluded by 20um Nitex mesh) and a separate 1.2 to 210um total sample. The filters were 1.2um silver membranes (Sterlitech) 13mm diameter. The samples were preserved by drying at 60C in a dedicated clean oven.  Prior to encapsulation, a 5mm diameter subsample was taken for biogenic silica analysis, which is delayed until there has been evaluation of the particle data from the flow cam and UVP. Samples were encapsulated in silver (Sercon sc0037) after acidification and drying. The decarbonated encapsulated POC samples were analysed by elemental analyser at the CSL UTAS by Dr Thomas Rodemann (EA TCD 960C, single point standardisation every 12 samples).  EA detection limit 0.001umol POC. POC and PON are presented as molar units. Blanks were process blanks (seawater) and 7% of the average for the combined data n=177. 1sd=0.12uM.
The ctd casts were all given the prefix K, so K001, K002 etc.  Not all stations were sampled due to budget constraints. Niskin is the Niskin bottle number.

Photographic images of seabird nesting sites in the Antarctic, collected by remote camera

The dataset comprises photographic images of seabird breeding colonies from cameras at multiple breeding sites across east Antarctic. Once deployed, the cameras operate continuously throughout the year and over multiple years but are programmed to take photographs on different schedules depending on the seabird species. The species include Adelie penguins, emperor penguins, Southern fulmars, Antarctic petrels, Cape petrels and Southern giant petrels. The cameras were positioned to include approximately 10-50 nests in the field of view. Photographs are taken frequently during the breeding season (1-10 photographs per day from October to March) and infrequently during the non-breeding season (1 photograph per week from March to October). Photographs are named by location, date and time (but not species).
The first cameras were deployed in November 2005 and the last camera was deployed in January 2012. Image acquisition is ongoing.

Strain fields on the Amery Ice Shelf using GPS

The data sets consist of static and kinematic GPS data collected on the mery Ice Shelf using Leica 399 receivers. Additional GPS data were collected at Beaver Lake, Hamm Peak, Moushino Is., New Year Nunataks, Jetty Peninsula, and Else Platform.
Most data are provided in UNIX Z compressed RINEX (Receiver INdependent EXchange) format, as described in the IGS standards - see http://www.igs.org/products
Some data are compressed using the RINEX Hatanaka compression scheme.
The standard RINEX file naming convention is used, i.e., an eight digit file name as bbbbddds.yyt, where bbbb refers to a four digit station name, ddd refers to the day number of the year, s refers to a session number and yyt is the file extension number where yy refers to the year and t defines the file type (o for observation file and n for navigation file. d indicates an observation file compressed using the Hatanaka compression scheme).  All files are compressed using the UNIX Z compression scheme, as shown by the extension .Z. For example, base0010.98o.Z, base0010.98n.Z, base0010.98d.Z.
The files are set out in the following directories on the submitted CD:

Airborne scanning LiDAR of sea ice during SIPEX in 2007

This data set is the airborne scanning LiDAR of a suite of different instruments deployed during the Sea Ice Physics and Ecosystems eXperiment (SIPEX) in 2007. Surveys have been flown over sea ice between 110-130
degrees E as part of the Australian Antarctic science project 2901.
Public Summary for project 2901
This research will contribute to a large multi-disciplinary study of the physics and biology of the Antarctic sea ice zone in early Spring 2007. The physical characteristics of the sea ice will be directly measured using satellite-tracked drifting buoys, ice core analysis and drilled measurements, with detailed measurements of snow cover thickness and properties. Aircraft-based instrumentation will be used to expand our survey area beyond the ship's track and for remote sampling. The data collected will provide valuable ground-truthing for existing and future satellite missions and improve our understanding of the role of sea ice in the climate system.
Project objectives:
(i) to quantify the spatial variability in sea ice and snow cover properties over scales of metres to hundreds of kilometres in the region of 110-130 degrees E, in order to improve the accuracy of sea ice thickness estimates from satellite altimetry and polarimetric synthetic aperture radar (SAR) data.
(ii) To determine the drift characteristics, and internal stress, of sea ice in the region 110-130 degrees E.
(iii) To investigate the relationships between the physical sea ice environment and the structure of Southern Ocean ecosystems (joint with AAS Proposal 2767).

Conductivity, Temperature and Depth (CTD) data from the SIPEX II voyage of the Aurora Australis

Multiple CTD (conductivity, temperature, depth) casts were deployed during the SIPEX II AAD Marine Science voyage in September-November 2012. The system uses a descending rosette capable of holding up to 24 CTD bottles. During this voyage the CTD rosette also housed two krill traps (using controllable lights) and two GoPro cameras contained in pressurised, waterproof containers that were used to monitor the krill traps and view objects both on the sea bed and in the water column.
Some functions of the GoPro cameras could be controlled from within the ship using the same transmission cable used by the CTD system. These functions included being able to change the focus setting of the cameras or start/stop recording. More information about the krill traps and cameras is contained in the SIPEX II Bottom Krill dataset.
When a bottle is 'fired' from the ship it briefly opens, draws in water samples and closes again. It is not reopened until it is brought on board the ship. Bottles are opened at different depths to obtain samples from these depths. The depths vary from cast to cast and so are recorded in the CTD Log sheets (contained in this dataset as PDF files).
Only raw data is contained in this dataset. The raw data was used by a variety of experiments during the SIPEX II voyage to produce results applicable to each experiment.
Thanks go to the P and O crew of the RV Aurora Australis for their assistance during CTD operations.

Fast Repetition Rate Fluorometer Data for the BROKE-West voyage of the Aurora Australis, 2006

At each CTD station the Fast Repetition Rate Fluorometer (FRRF) was carried out onto the trawl deck and shackled (+ cable tie) to the winch cable. When the crew in the aft control room were ready the PAR (Photosynthetically Active Radiation) cap was removed and the FRRF activated with the magnet. It was deployed at a rate of  0.3m/sec to 10m, stopped for 30sec, then the descent was continued to 100m at same rate where it was stopped for another 30 sec. The FRRF was then brought back up at 0.3m/sec to deck. Once on deck the FRRF was turned off, it was hosed down with hot fresh water and the PAR cap replaced. Underway data were collected from the flow-through system in the lab on all South/North transects. West to East legs were not surveyed. The FRRF data were downloaded after every Vertical Drop and at the end of the Underway legs. The post-processing and analysis of data will be carried out after the voyage. The Final dataset is in the form of a Binary file for each drop and Underway leg.
This work was completed as part of ASAC projects 2655 and 2679 (ASAC_2655, ASAC_2679).
