AAS 4087 Fulmarine petrel tracking study, Hop Island, 2015/16

The foraging ecology of three fulmarine petrels including Cape petrels, Southern fulmars and Antarctic petrels were investigated at Hop Island during the 2015/16 austral summer. Two datasets were generated: 1) tracking data from Fulmarine petrels, and 2) stable isotope analysis of blood, feathers and egg shells. Tracking data were collected using Ecotone GPS trackers attached to the birds back feathers with tape. Location data has been interpolated using great circle distance to a time step of 15 minutes and include a record of whether the bird dived during that time period or not. Each location point was assigned a breeding stage (incubation or chick rearing) based on individual nest activities. Stable isotope ratios of carbon (13C/12C) and nitrogen (15N/14N) were determined by analysing 1 mg aliquots through continuous flow - elemental analysis - isotope ratio mass spectrometry (CF-EA-IRMS). Isotopic values of blood reflect approximately the last 52 days before sampling and thus the incubation period of all three species. Egg membranes and feathers remain metabolically inert after formation, and hence reflect the trophic niche during the pre-laying and moult period, respectively. We collected moult feathers during the chick-rearing period and therefore assumed that these were formed one year prior to the collection date and thus represent the trophic niche of the chick-rearing period one year earlier (austral summer 2014-15).

CEAMARC-CASO 12kHz Bathymetry - data collected from voyage 3, 2007-2008 of the Aurora Australis

Bathymetry data was collected using a Simrad EK60 echosounder.  The sample data have been corrected for the relative locations of GPS antenna, transducers and waterline.  A sound-speed value of 1500 m/s was applied when calculating depth.
The seafloor depth itself was defined firstly as the depth of the sounder-detected bottom minus 10m (contact Simrad for more information about their bottom-detection algorithm), and then modified manually where necessary to ensure that the line followed the seafloor as perceived by eye from the echogram. This is therefore a subjective process, and the true seafloor depth may vary from the perceived depth by several hundred metres in the worst cases. The greatest uncertainties are typically at greater depths, e.g. greater than 1000 m.
This seafloor depth line therefore refers to the approximate depth (not range from transducer) of the seafloor less 10 m, i.e. 10 m should be added to the 'depth' values in the *.CSV file to give the 'true' seafloor depth.
Depths  greater than 5000 m are not available due to the 12 kHz data not being logged any deeper than this.
These data are preliminary and subject to change.
Bathymetry data was exported during the voyage by Belinda Ronai.  Post voyage enquiries however should be directed to Toby Jarvis.

Airborne-deployed ocean sensors in the Southern Ocean, 2016-2018, Level 0 data

Extracted Level 0 data are provided as audio files recorded in flight with a Sony PX470 voice recorder. These files were processed to generate the associated Level 2 products.
Project 4346 demonstrated the use of Airborne eXpendable Bathy-Thermograph (AXBT) and Airborne eXpendable Conductivity, Temperature, Depth (AXCTD) sensors from a BT-67 Basler aircraft in East Antarctica. The primary objective was to use AXBT and AXCTD sensors to infer seafloor depth where no previous measurements had been made by ship, often by deploying sensors into narrow gaps in sea ice. Inferring a snapshot of the ocean state by detecting major thermoclines was a secondary objective.
Although several sensors were purchased with external funds, the efforts to develop operational and subsequent data analysis approaches were unfunded as this was an add-on, target of opportunity. The effort is best described as a prototype demonstration project to test whether the seafloor depth could be inferred beneath narrow sea ice leads from a rapidly flying aircraft. All but eight AXBT sensors were donated to the University of Texas Institute for Geophysics (UTIG); AXCTDs were purchased by the Antarctic Gateway Partnership. Receiver and data processing equipment were loaned to UTIG.

Nella Dan: FIBEX Cruise - Zooplankton data

This dataset contains results from the First International BIOMASS Experiment (FIBEX) cruise of the Nella Dan. It is the first cruise in a series of six designed to assess the distribution and abundance of krill, Euphausia superba.
The FIBEX was an international programme co-ordinating the activities of 12 ships from 11 nations in the Southern Atlantic and Indian Oceans. Australia was responsible for surveying an area of the southern Indian Ocean south of 60 degrees and between 60 degrees and 90 degrees east longitude. Surveys of krill and other zooplankton were taken off Antarctica in the Australian sector (Mawson to Davis region) and Prydz Bay in January and March 1981. Species identity and abundance data were obtained. The major species investigated were Euphausia superba, Euphausia frigidia, Euphausia crystallorophias and Thysanoessa marcuria. Other pteropods and cephalopods were also studied.
Physical and chemical oceanography data and phytoplankton samples were also  obtained, as well as results from hydroacoustic surveys of krill biomass.
Several files are available for download at the provided URL.  They include excel spreadsheets on summarised data, catch composition data and station lists.  Furthermore a pdf document of the report produced from the cruise is also available for download.

Cape Shirreff female Antarctic fur seal geolocation tracking data

To quantify the post-breeding movements of adult female Antarctic females (Arctocephalus gazella) we tracked females using Biotrack GLS (geolocation) data loggers. Females were captured towards the end of the lactation period (March/April) and the GLS tag, affixed to a Dalton flipper tag, was deployed in the trailing edge of the left or right foreflipper. Tags were generally retrieved just prior to or after giving birth the following season. Data files were extracted from the tags using BASTrak software. 
.lig - light data
.tem - temperature data
.act - activity data
Metadata for each individual include:
Site, year, GLS ID, sex, age, deployment site, lat and long of deployment site, flipper tag number, deployment and retrieval times (GMT).

Bathymetric data of Long and Tryne Fjords at Vestfold Hills, Antarctica, collected in December 1999

This dataset contains 102 depth measurements of the water column in Long and Tryne fjords, which are in the northern Vestfold Hills, Prydz Bay, Antarctica. Sea ice thickness and snow thickness were recorded simultaneously. The motivation for this project has been to yield a description of the pupping and moulting habitat of Weddell seals. This information will assist the interpretation of 25+ years of data on seal distribution within that area.
Our data were collected between 7th and 13th December 1999. The measurement sites were chosen according to geographical features; their exact location was determined by GPS with an accuracy of about 25m. At each site a 5cm diameter hole was drilled through the sea ice and a weighted measurement tape was lowered through the ice-hole to the bottom. Water depths were measured to the nearest centimetre; ice and snow thicknesses were measured to the nearest millimetre. A minimum depth of less than 3m was found in a narrow channel between small islands immediately west of Shirokaya Bay. The maximum depth of the water column was 222m in the middle basin of Long Fjord. The tidal range for the measured days was less than 0.5m, with tidal corrections applied to the raw data. Water samples were taken in Breid Basin and the middle basin of Long Fjord. These and water samples taken in Snezhnyy Bay [pers. comm. J. Laybourn-Parry, 1999] show aerobic and relatively fresh water for all upper basins. This indicates that even the far basins of both fjords are well mixed despite the drainage of large volumes meltwater from the Antarctic plateau into the fjords.
See related URL for data and a spatial summary of the data.
See Entry: long_tryne_bathy for an interpolation of bathymetry made using the Topogrid command within the ArcInfo GIS software, version 8.0.2. Coastline and spot height (heights above sea level) data, extracted from the Australian Antarctic Data Centre's Vestfold Hills topographic GIS dataset (see Entry: vest_hills_gis), was also used as input data to optimise the interpolation close to the coastline.
