This dataset contains data files, processing templates and documentation relating to the BROKE-West multifrequency echosounder (acoustic) survey carried out from the RSV Aurora Australis in the austral summer of 2005/06 (ASAC project 2655). The primary aim of the acoustic survey was to describe the distribution and abundance of Antarctic krill (Euphausia superba) in CCAMLR Division 58.4.2. However, these data are also relevant for studies of other sound-scattering targets detected by the echosounder system, for example other pelagic taxa or the seafloor. The dataset is a collection of *.csv data files, *.ev processing files and *.pdf documentation files, organised into 4 categories: 1. Acoustic survey: data files relating to the transects undertaken for the acoustic survey 2. Acoustic data processing: metadata files, processing templates and documentation relating to the collection and processing of the acoustic data 3. Acoustic results: results arising from the processing of the raw data. The raw data are described in a separate metadata record - "AAD Hydroacoustics hard disks - data collected from Southern Ocean cruises..." 4. Ancillary data: additional non-acoustic data used during the processing of the acoustic data The file "data_fields.pdf" lists and describes the fields in each of the *.csv data files. The file "processing_methods.pdf" provides a synopsis of the methods by which the raw acoustic data were collected and processed. The BROKE-West survey was conducted on voyage 3 of the Aurora Australis during the 2005-3006 season. It was intended to be a comprehensive biological and oceanographic survey of the region between 30 degrees and 80 degrees east.

Metadata record for data from ASAC Project 2753 See the link below for public details on this project. Public Weddell and southern elephant seals are high-order predators living in the Antarctic marine ecosystem. Their place in that ecosystem is the result of a long history of evolutionary adaptation to a challenging and changing environment. The objective of this study is to understand how Weddell and elephant seals have adapted and are responding to today's rapidly changing Antarctic environment. This study will use current and innovative approaches in demographic (population) analyses and diet techniques to analyse changes in the seals' demographic parameters and historical aspects of their ecology. Project objectives: Objective 1. Seek a greater understanding of the links between climate based environmental parameters and Weddell seal demographic performance. Objective 2. Test the hypothesis that the foraging ecology and presence of male southern elephant seals hauling out along the Antarctic coast are regulated by variation in the extent and concentration of coastal sea-ice. Objective 3. Examine contemporary and historical dietary shifts in an Antarctic marine predator by using a non-invasive technique, stable isotope analyses. Objective 4. Construct models of potential population performance for Weddell and southern elephant seals with predicted climate change Taken from the 2008-2009 Progress Report: Progress against objectives: The first season of field work was conducted at Casey in December 2008. This comprised of surveys of the region to locate breeding and moulting haulouts, weighing and flipper tagging of Weddell seal pups and flipper tagging of sub adult elephant seals. Specifically: Tagging Leptonychotes weddellii. A total of 30 pups were flipper tagged. Tagging: 46 sub-adult male Mirounga leonina in Browning Peninsula region. Aerial survey of the Casey fast-ice conducted on 30/1/2009. Conducted at 1000, 500, 300 ft. A total of 33 seals counted. Taken from the 2009-2010 Progress Report: Progress against objectives: 1. Observations of tagged Weddell seals made in the Vestfold Hills during the breeding season. 2. Counts were made of elephant seals at Davis station 3. No progress made due to postponement of project at Casey 4. Data collected on Weddell and elephant seals at Davis. No modelling undertaken in this year

Metadata record for data from ASAC Project 2914 See the link below for public details on this project. Can animals raft between countries on floating seaweed? We aim to answer that question using powerful genetic tools. We can tell whether gene flow is strong between populations of animals by comparing their mitochondrial DNA; this could show us whether animals from one species in New Zealand are isolated from individuals of the same species in Chile. If they are not isolated, how are they managing to maintain gene flow? We know there are many millions of clumps of floating seaweed in the Southern Ocean, and these might provide a means of intercontinental travel for a range of small invertebrates. Project objectives: The primary objective of the project is to determine the effectiveness of rafting as a dispersal mechanism for sessile and semi-sessile organisms around the Southern Ocean using genetic tools. The secondary objectives, by which the primary objective will be addressed, are: - to examine the biogeography of bull kelp (Durvillaea antarctica) and its holdfast fauna around the Southern Ocean - to undertake genetic analysis of a wide range of macroalgal (seaweed) species throughout the Southern Ocean to assess 1) whether sea ice indeed extended further north than previously believed, and 2) the ecological and evolutionary impacts of historic ice scour on Southern Ocean islands. - to determine which holdfast invertebrates are the most common and ubiquitous in holdfasts of Durvillaea antarctica around the Southern Ocean - to compare the genetic structure of populations of both the kelp itself, and select invertebrate taxa* from its holdfasts, on a number of spatial scales: --- genetic variation at HOLDFAST level: are members of a single species, e.g., the isopod Limnoria stephenseni, closely related within a single holdfast? --- genetic variation at SITE level: are members of a single species, e.g., Durvillaea antarctica itself, closely related at one site? In this case, a 'site' means a single intertidal rock platform. --- genetic variation at NATIONAL level: are there distinct biogeographic separations of species, or does a single species show distinct genetic disjunction, along the Chilean coastline and around the south island of New Zealand? --- genetic variation at OCEAN level: are species clearly connected (by gene flow) between Southern Ocean landmasses? The landmasses of interest are: Chile, New Zealand, and the subantarctic islands on which Durvillaea antarctica grows. * The proposed taxa that this project will focus on are: the isopod genus Limnoria; the amphipod Parawaldeckia kidderi; the chiton genus Onithochiton; the polychaete worm families Terebellidae and Syllidae; a topshell; a bivalve; barnacles. Progress against objectives: Considerable progress has been made against the primary objective since the start of the project in 2006. We have collected (/ been sent) and analysed samples of bull-kelp (Durvillaea antarctica) and its associated invertebrate holdfast fauna from numerous sites around the Southern Ocean (subantarctic islands including Macquarie, Gough, Marion, Kerguelen, Crozet, Auckland, Antipodes, Campbell, Falkland Islands; along the coasts of New Zealand and Chile). Our results thus far have allowed us to determine not only that rafting facilitates long-distance dispersal of these otherwise sedentary taxa, but also that sea ice during the last ice ice likely had significant impacts on subantarctic intertidal ecosystems. Our conclusions have been published in several papers in high-impact journals. The secondary objectives, by which the primary objective will be addressed, are: - to examine the biogeography of bull kelp (Durvillaea antarctica) and its holdfast fauna - these objectives have now largely been achieved, and results published. - to undertake genetic analysis of a wide range of macroalgal (seaweed) species throughout the Southern Ocean - this part of the project is ongoing, and will make use of samples collected over the austral summer from Macquarie Island (and other locations around the southern hemisphere). all samples have now been collected and are being processed in the laboratory. - to determine which holdfast invertebrates are the most common and ubiquitous - this objective has been partially achieved (see Nikula et al. 2010), but research is ongoing. - to compare the genetic structure of populations of both the kelp itself, and select invertebrate taxa from its holdfasts, on a number of spatial scales - this objective has been partially achieved (see Nikula et al. 2010 for results of Limnoria and Parawaldeckia genetic research) but additional research on these and other taxa continues. The download file contains an excel spreadsheet detailing collection locations and accession numbers for the samples collected on Macquarie Island. A text document providing accession numbers for non-Antarctic related samples used in this project is also part of the download file.
