Through-ice communication by Weddell seals may not be practicable

Possible communication between territorial male Weddell seals (Leptonychotes weddellii) under the ice with females on the ice was investigated.  In-air and underwater recordings of underwater calls were made at three locations near Davis, Antarctica.  Most underwater calls were not detectable in air, often because of wind noise.  In-air call amplitudes of detectable calls ranged from 32-74 dB re. 20 microPa at 86 Hz down to 4-38 dB re. 20 microPa at 3.6 kHz. Most of these would be audible to humans.  Only 26 of 582 amplitude measurements (from 230 calls) ranged from 5 dB to a maximum of 15 dB above the minimum harbour-seal (Phoca vitulina) in-air detection threshold.  Seals on the ice could likely hear a few very loud underwater calls but only if the caller was nearby and there were no wind noises.  The low detectability of underwater calls in air likely precludes effective communication between underwater seals and those on the ice.

CTD Data from the toothfish fishery at Heard Island and McDonald Island

Australian vessels fishing in the Commonwealth managed fishery for Patagonian Toothfish and mackerel icefish in the Heard Island and MacDonald Island area deployed conductivity, temperature and depth (CTD) loggers attached to their fishing gear. In most cases CTDs were deployed on demersal longlines but in some cases they were attached to trawl nets and traps.
Data were collected on five fishing vessels during the fishing seasons of 2019/20 and 2020/21
The data were collected with a CTD (Conductivity, Temperature and Depth Recorder) from the Sea Mammal Research Unit (SMRU) at St Andrew’s University Scotland. Files were downloaded with their TagConfig software in text (.txt) format. Recordings were made at (typically) 1 second intervals for the duration of the fishing event, recording data throughout the water column while setting the gear, then while fishing on the sea floor and again through the water column when the gear was retrieved. Each data file has data on date/time, pressure referenced to surface pressure (dbar), absolute pressure (dbar), temperature (°C), conductivity *mS/cm) and salinity (psu). The data are currently not linked to geographical coordinates which are confidential, but these may be able to be released on contact with the data owner and subject to appropriate confidentiality arrangements.
Number of deployments: 
2019/20: 25
2020/21: 27

Photogrammetric video tracks of Antarctic blue whale movements recorded during the 2015 NZ Australia Antarctic Ecosystems Voyage

During the 2015 New Zealand-Australia Antarctic Ecosystem Voyage a digital photogrammetric video tracking system was used to collect precise surfacing locations during encounters with some Antarctic blue whales. The photogrammetric video tracking system is a modern digital video version based on the same operating principle as the that described by Leaper and Gordon 2001, and enables determination of the range and bearing to tracked objects relative to the ship. 
Around 15 hours of video tracking were recorded of which 8 hours were classified as good quality of a single animal or in one case a pair of animals that stayed close together. Focal follows were aborted when it was no longer possible to follow the focal animal due to ice or when the presence of other animals meant it was no longer possible to be sure which was the focal animal. This resulted in 7 tracks of longer than 45 minutes with the longest around 2 hours.

Royal Penguins at Macquarie Island

This dataset contains the results from surveys of Royal Penguins (Eudyptes schegeli) on Macquarie Island. The surveys were conducted between May 1984 and January 1985. The total number of Royal penguins breeding on Macquarie Island is estimated at 848,719 pairs (+/-10.5%). The sizes and locations of all 57 colonies are given. The results are listed in the documentation.
All Royal penguins breeding at Macquarie Island were allocated to one of 57 colonies identified by locations and varying in size from 75 breeding pairs to over 160,000 breeding pairs.  The mean number of nests in the Lower Sandy Bay plots was 2.43/m2 (range at 95% confidence limits 2.32-2.54).  The occupied area given for Hurd Point colony has been reduced by 5% from that surveyed to allow for two areas included in the survey which were subsequently found not to be used by breeding birds in the 1984-85 season.  The variation in the difference between the lower and upper estimates of individual colonies given in Table 2 ranges from 17% to 50%.  This was mainly due to the extreme variability of the terrain and/or the degree of association with Rockhopper penguins.  The number of breeding pairs calculated for the colonies surveyed through the winter was 487,932 (range 465,838 - 510,014).  The total estimated for the unsurveyed colonies was 360,787 (range 294,100 - 427,475) breeding pairs.  The total estimated number of breeding pairs of Royal penguins on Macquarie Island is 848,719 +/- 10.5% (range 759,938 - 937,489).
The dataset includes two text files (csv format) detailing the number of breeding pairs at each colony, and an sketch map of Macquarie Island detailing the locations of the colonies.

Integrated Reef Fish Monitoring Project (IMR)

The project focuses on monitoring reef fish assemblages in deep-water inter reef areas, inshore nursery grounds and fringing reefs of high continental islands. The surveys will first set monitoring baselines for offshore deep water inter-reefal fish communities beyond safe limits of SCUBA based surveys. Underwater Visual Census survey will occur on 8 island groups using transect based methods (Emslie &amp; Cheal, 2018). Nursery seascapes will be surveyed with RUVS (non-baited BRUVS) and BRUVS to survey fishes various habitats (estuary, mangrove, seagrass, reef flat) in three seascape elements (coastal, inter-reef, and continental island).
BRUVS and ROVs will be employed for data acquisition in three nodes, the northern, central and southern GBR. Sampling will be a spatially balanced design among different habitats (e.g. shoals, Halimeda banks, sponge gardens) as well as Marine Park zoning.

Foraging of royal penguins and its relationship to the Antarctic Polar Frontal Zone

The factors that control the number of animals in a population are often difficult to understand.  However, this basic understanding is central to managing those populations and assessing how they might respond to human induced pressures. For animals living in the Antarctic, like penguins, the marine environment that they depend on for food can vary due to natural events such as El Nino, and potentially due to human induced changes such as global warming. This study uses modern computer technology to track Royal penguins at sea and to monitor their time on land.   By relating where the birds go to feed, what they feed on, and how successfully they catch their food to the survival rates of their chicks, this study will describe how fluctuations in a major Antarctic oceanographic feature (the Antarctic Polar Front) can influence the size of the Royal penguin population at Macquarie Island.
Information on breeding success, diet and foraging success were collected each year between 1997-2001. Diving behaviour and at-sea movements were also quantified between 1997 and 1999.
These data will also be available in the ARGOS satellite tracking database.
Attached to this metadata record are ARGOS tracking data collected by Cindy Hull between 1994 and 2000.  The tracking data have been collected from 19 different royal penguins.  The download file contains a csv file with tracking data.

Census of Antarctic Marine Life (CAML) Archive of Project Documentation - CAML_Project_Archive.Ships

The Census of Antarctic Marine Life (CAML) Project Archive is a collection of scanned documents, maps, videos, and other related material that comprise the organisation and management documentation associated with a major research project of international significance. CAML measured the distribution and abundance of life in the Southern Ocean around Antarctica so that future impacts of climate change and human activities can be better understood. CAML coordinated the largest-ever survey of the Southern Ocean with 18 voyages in Antarctic waters, and inventoried over 16,000 marine species with hundreds new to science, provided DNA barcodes for 1,500 species, and has so far produced more than 600 scientific publications. CAML is a key activity of the Scientific Committee on Antarctic Research (SCAR); a subproject of the Census of Marine Life (CoML); and was a major initiative of the 2007-2009 International Polar Year (IPY).
