The Commission for the Conservation of Antarctic Marine Living Resources has recently decided to re-adopt the generalised yield model (GYM) as an assessment tool to progress the management of Antarctic krill (Euphausia superba). To this end…
There are many advantages to transitioning from conducting marine wildlife surveys via human observers onboard light-aircraft, to capturing aerial imagery using drones. However, it is important to maintain the validity of long-term data series whilst transitioning from observer to imagery surveys.
Molecular tools are increasingly applied for assessing and monitoring biodiversity and informing conservation action. While recent developments in genetic and genomic methods provide greater sensitivity in analysis and the capacity to address new questions…
Net sea-ice extent (SIE) and sea-ice area (SIA) were well below or at record-low levels for all of 2022 (based on satellite passive-microwave ice concentration data since 1979 when the near-homogenous satellite record began; Cavalieri et al. 1996). Indeed…
The Southern Ocean Research Partnership (IWC-SORP) is a multi-lateral, non-lethal scientific research programme established in 2009 to improve the coordinated and cooperative delivery of science to the IWC. There are 13 Partners: Argentina, Australia, Belgium, Brazil, Chile, France, Germany, Italy…
Introduction: This document updates the research bibliography of SC/66b/SAN01 presented in 2016. The Southern Ocean Sanctuary (SOS) was established by the Commission in 1994. The area covered by the SOS in combination with the complementary Indian Ocean Sanctuary (IOS) is shown in Figure 1.
To understand the scope and scale of the loss of biodiversity, tools are required that can be applied in a standardized manner to all species globally, spanning realms from land to the open ocean.
Contracting governments to the International Convention for the Regulation of Whaling are required to provide an annual National Progress Report summarising cetacean related activities annually.
Following open, competitive Calls for Proposals in 2016/17, 2018/19 and 2019/20 a total of £144,058 GBP, £489,154 GBP and £129,955 GBP, respectively, were allocated from the IWC-Southern Ocean Research Partnership (IWC-SORP) Research Fund to 31 research projects in total. In addition…
Blue whale populations each produce distinctive repeated songs that are stable over periods of decades, and can be used to identify where each population resides and moves. In the Southern Hemisphere and northern Indian Ocean, there are at least seven distinct populations based on their songs…
The overall goal of the SC Communication Initiative is to develop new communication tools and material tailored to IWC Commissioners as the principal audience. This material is also likely to have value for other policy makers, non-government organisations, government organisations in non?
Antarctic krill are a fundamental component of Southern Ocean ecosystems and perturbations to krill populations have ramifications for the entire ecosystem. Krill are fished across the Southern Ocean and sustainable management of this fishery is a high priority for the Australian Government.
INTRODUCTION The Commission and the Scientific and Conservation Committees have adopted numerous recommendations over the years for strengthening engagement with other organisations. The IWC Secretariat, in collaboration with members of the SC and CC have been working to carry out these mandates…
Introduction … Miller and Kelly (2023) provides some guidelines on spatial model-based estimation of abundance (and its uncertainty) from counts of cetaceans obtained using standard distance sampling line transect surveys.
Development of CCAMLR krill fishery management: Antarctic krill (Euphausia superba) is both abundant and broadly distributed in the Southern Ocean, with most of its life history stages considered important prey items for a wide variety of organisms (Trathan and Hill 2016).
Report submitted to CCAMLR: Leaper, R., Biuw, M., Favero, M, Forster, I., Johnson, C., Kelly, N., Heinemann, D., Hines, E., Landry, S., Mattila, D., Meyer, M., Parker, S., Passadore, C., Reeves, S., Soffker, M., Stimmelmayr, R., Walker, N., 2022.
The SCAR Krill Expert Group (SKEG) aims to improve the understanding of krill biology and ecology and serve as a link between the scientific krill community and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which manages the Antarctic krill fishery.
The scope of this document is model-based estimation of abundance (and its uncertainty) from counts of cetaceans obtained using standard distance sampling line transect surveys (e.g., Buckland et al., 2015).
A proof-of-concept study was conducted to explore the viability of automated acoustic detection of upcall vocalisations produced by southern right whales (Eubalaena australis) on their high-latitude Antarctic feeding grounds. The automated acoustic detector used was that of Shiu et al (2020)…
Background … Satellite tags were deployed on 50 east Australian humpback whales (breeding stock E1) between 2008 and 2010 on their southward migration, northward migration and feeding grounds in order to identify and describe migratory pathways, feeding grounds and possible calving areas.
As the use of coastal and offshore environments expands, there is a need to better understand the exposure of marine megafauna to anthropogenic activities that potentially threaten their populations. Individual satellite telemetry studies are often hampered by small sample sizes…
In response to a report of the incidental mortality of three juvenile humpback whales in the Antarctic … krill trawl fishery in Subareas 48.1 and 48.2 during the 2021 calendar year, SC-CAMLR reconvened … the Working Group on Incidental Mortality Associated with Fishing (WG-IMAF).
Physical features preserved in ice cores may provide unique records about past atmospheric variability. Linking the formation and preservation of these features and the atmospheric processes causing them is key to their interpretation as palaeoclimate proxies. We imaged ice cores from Law Dome…
To ensure effective restoration and environmental protection of fuel spill sites on Macquarie Island that have undergone remediation, the Australian Antarctic Division has developed site-specific Environmental Quality Guidelines and Remediation Targets.
