Elephant Seal and Toothfish interations in longline fisheries

Edited version of a video showing three elephant seals interacting with a toothfish longline.
Taken from the abstract of the referenced paper:
Humans have devised fishing technologies that compete with marine predators for fish resources world-wide. One such fishery for the Patagonian toothfish (Dissostichus eleginoides) has developed interactions with a range of predators, some of which are marine mammals capable of diving to extreme depths for extended periods. A deep-sea camera system deployed within a toothfish fishery operating in the Southern Ocean acquired the first-ever video footage of an extreme-diver, the southern elephant seal (Mirounga leonina), depredating catch from longlines set at depths in excess of 1000m. The interactions recorded were non-lethal, however independent fisheries observer reports confirm elephant seal-longline interactions can be lethal. The seals behaviour of depredating catch at depth during the line soak-period differs to other surface-breathing species and thus presents a unique challenge to mitigate their by-catch. Deployments of deep-sea cameras on exploratory fishing gear prior to licencing and permit approvals would gather valuable information regarding the nature of interactions between deep diving/dwelling marine species and longline fisheries operating at bathypelagic depths. Furthermore, the positive identification by sex and age class of species interacting with commercial fisheries would assist in formulating management plans and mitigation strategies founded on species-specific life-history strategies.

Long-term underwater acoustic recordings 2013-2021

This dataset contains long-term underwater acoustic recordings made under Australian Antarctic Science Projects 4101 and 4102, and the International Whaling Commission’s Southern Ocean Research Partnership (IWC-SORP) Southern Ocean Hydrophone Network (SOHN). 
Calibrated measurements of sound pressure were made at several sites across several years using  custom moored acoustic recorders (MARs) designed and manufactured by the Science Technical Support group of the Australian Antarctic Division. These moored acoustic recorders were designed to operate for year-long, deep-water, Antarctic deployments. Each moored acoustic recorder included a factory calibrated HTI 90-U hydrophone and workshop-calibrated frontend electronics (hydrophone preamplifier, bandpass filter, and analog-digital converter), and used solid state digital storage (SDHC) to reduce power consumption and mechanical self-noise (e.g. from hard-drives with motors and rotating disks). Electronics were placed in a glass instrumentation sphere rated to a depth of 6000 m, and the sphere was attached to a short mooring with nylon straps to decouple recorder and hydrophone from sea-bed. The hydrophone was mounted above the glass sphere with elastic connections to the mooring frame to reduce mechanical self-noise from movement of the hydrophone. The target noise floor of each recorder was below that expected for a quiet ocean at sea state zero. The analog-digital converter, based on an AD7683B chip, provides 100 dB of spurious free dynamic range, but a total signal-to-noise and distortion of 86 dB which yields 14 effective bits of dynamic range at a 1 kHz input frequency. 
 The data for each recording site comprise a folder of 16-bit WAV audio files recorded at a nominal sample rate of 12 kHz. The names of each WAV file correspond to a deployment code followed by the start time (in UTC) of the file as determined by the microprocessor’s real-time clock e.g. 201_2013-12-25_13-00-00.wav would correspond to a wav file with deployment code 201 that starts at 1 pm on December 25th 2013 (UTC). 
Recording locations were chosen to correspond to sites used during AAS Project 2683. These sites were along the resupply routes for Australia’s Antarctic stations, and typically there was only one opportunity to recover and redeploy MARs each year.

Atmospheric carbon dioxide (CO2) concentrations for CO2 flux

During the ice stations, measurements of the air CO2, concentration for CO2 flux between sea ice and atmosphere were made with the chamber technique. Air-sea ice CO2 fluxes were measured over the sea ice with semi-automated chambers. Sample air from the chamber is passed through Teflon tubes connected to non-dispersive infrared (NDIR) analyzer (Model 800, LICOR Inc., USA) that was connected to a system controller and data logger (Model 10x, Campbell Scientific Inc., USA), that controls the opening/closing of the chambers as well.  During the observation period, the CO2 flux was measured under three different conditions or surface types: (1) a chamber was installed above snow; (2) over the bare ice after removing the snow; (3) slush layer after removing the snow and slush crystals. The CO2 concentration in the chamber was measured every 5 s during experiments lasting 20 minutes for each chamber. A one hour cycle of measurements therefore consist of three 20 minute periods from each chamber (i.e. surface type).  
Data available: excel files containing sampling station name for each spreadsheet, dates, sampling time and air CO2 concentration as output voltage from NDIR (to indicated as ppm we need to calculate, but, not yet done this process) in the air and chamber for CO2 flux measurement.

Macquarie Island: A window into the oceanic crust and upper mantle

Because of the inaccessibility of the deep-ocean floor, our knowledge about the composition and structure of the oceanic crust is very limited. Macquarie Island is the only fragment of ocean crust exposed above sea-level in the world, providing a unique opportunity to study the ocean crust directly in unprecedented detail.
From the abstract of the referenced paper:
Macquarie Island preserves largely in-situ Miocene oceanic crust and mantle formed at a slow-spreading ridge.  The crustal section on the island does not conform to a simple 'layer cake pseudo-stratigraphy', but is the result of multiple magmatic episodes.  Macquarie Island crust did not grow by top-down cooling, but rather from the base up.  Peridotites cooled first and formed the basement into which gabbro plutons were intruded.  This was followed by cooling and deformation, and by intrusion of dykes that fed a sheeted dyke-basalt complex.  Finally, lava filled grabens were formed.  These relative age relations rule out simple co-genetic relations between rock units.

Satellite tracks of humpback whales generated from tag deployments during the Antarctic Whale Expedition (AWE) 2009/10

Satellite derived tracks of humpback whales tagged on their Antarctic feeding grounds.
Data can be found here: https://data.aad.gov.au/aadc/argos/display_campaign.cfm?campaign_id=83
Satellite tags were deployed on adult humpback whales with a modified version of the Air Rocket Transmitter System (ARTS, Restech) and a purpose-designed projectile carrier at a pressure of 7.5 – 10 bar. A custom-designed, 80mm anchor section is attached to a stainless steel cylindrical housing containing a location-only transmitter (SPOT-5 by Wildlife Computers, Redmond, Washington, USA and Kiwisat 202 Cricket by Sirtrack, Havelock North, New Zealand). This superseded anchor design resulted in the anchor section disarticulating upon deployment in order to achieve improved tag retention times while minimising impact. The tags were sterilised with ethylene oxide prior to deployment and implanted up to 290mm into the skin, blubber, interfacial layers and outer muscle mass of the whale. Tags were programmed to transmit to the Argos satellite system at various duty cycles and repetition rates for a maximum of 720 transmissions per day. These transmissions are relayed to processing centres which calculate the transmitter’s location by measuring the Doppler Effect on transmission frequency.

Euphausiid-specific metabarcoding data from eDNA samples collected on the TEMPO voyage

This is a Euphausiid-specific metabarcoding dataset of Southern Ocean eDNA samples collected on the TEMPO voyage in 2021. We collected eDNA samples by filtering five litres of seawater in the East Antarctic Southern Ocean from the surface and seafloor as well as in and near krill swarms(n = 110). After DNA extraction, a Euphausiid-specific metabarcoding marker was used to determine the presence of different Southern Ocean krill species in each sample. 
Detailed methods are available in the following publication: 
Suter L et al. (2025) Monitoring Antarctic krill (Euphausia superba) distribution in the Southern Ocean: environmental DNA (eDNA) adds to the toolbox. Frontiers in Marine Science. 
The data provided here contains
- raw paired end sequencing data in fastq format for each sample
- R markdown code to process the raw data in order to identify unique sequences, and which sequences are contained in which samples
- a tag file that identifies which multiplex-identifier (MID) tags were used in forward and reverse primers for each sample
- a zOTU table that identifies which sequences were detected in each sample, and what taxonomy was associated with each sequence.

MODIS Derived Sea Surface Temperature dataset: Seasonal Variations

The dataset measures the long-term seasonal variations of the sea surface temperature (SST) of ocean surface waters. They are derived from MODIS (aqua) images using NASA's SeaDAS image processing software. The monthly SST images between July 2002 and December 2017 are used to calculate the standard deviations of the four austral seasons: winter (June, July, and August), spring (September, October and November), summer (December, January and February) and autumn (March, April and May). The extent of the dataset covers the entire Australian EEZ and surrounding waters (including the southern ocean). The unit of the dataset is Celsius degree.
This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

Winter foraging ranges of Weddell seals: a pilot study to assess their role in the winter sea-ice zone and their potential as ocean sampling platforms

Metadata record for data from ASAC Project 2695
See the link below for public details on this project.
Variations in the winter extent of sea ice are thought to have profound effects on biological productivity, such as algal growth and the reproduction of Antarctic krill, with subsequent flow-on effects through the food web. This pilot study aims to measure the winter foraging patterns of Weddell seals (Leptonychotes weddellii) as a first step in investigating their role in the winter sea-ice zone. Our specific objectives are to:

Obtain satellite tracks from a sample of adult female Weddell seals
Collect diving behaviour (dive depth, duration and frequency) from a sub-set of these seals
Collect high precision water temperature data from a subset of these seals

These data will enable us to assess the feasibility of including Weddell seals as a candidate species in a long-term study of winter sea-ice and predator performance. 
This project has now been merged into project number 2794 (ASAC_2794).  It also contains data collected as part of project 1171 (ASAC_1171).
The download file contains 13 Access Databases containing data from this project.  An excel spreadsheet summarising the databases is also included.
The data have also been loaded into the Australian Antarctic Data Centre's ARGOS tracking database.  The database can be accessed at the provided URL.
