Antarctic terrestrial biodiversity faces multiple threats, from invasive species to climate change. Yet no large-scale assessments of threat management strategies exist. Applying a structured participatory approach…
Human-caused climate change worsens with every increment of additional warming, although some impacts can develop abruptly. The potential for abrupt changes is far less understood in the Antarctic compared with the Arctic, but evidence is emerging for rapid…
Ethical and effective data sharing is essential for best-practice, evidence-based invasive species management. While the tools and willingness to use data sharing platforms are increasing within the environmental research community…
For nearly 3 decades, geodetic Global Navigation Satellite System (GNSS) measurements in Antarctica have provided direct observations of bedrock displacement, which is linked to various geodynamic processes, including plate motion, post-seismic deformation, and glacial isostatic adjustment (GIA).
Antarctica and the Southern Ocean are key elements in the physical and biological Earth system. Human-induced climate change, and other human activities in the region, are leading to several potential interacting tipping points with major and irreversible consequences. Here…
Hundreds of large whales have been tracked using consolidated (Type-C) satellite tags, yet there have been few studies on their impacts on whale health. In 2011, we initiated the first study designed to evaluate the effects of these tags on a baleen whale. Between 2011 and 2018…
Improving our understanding of the effects of satellite tags on large whales is a critical step in ongoing tag development to minimise potential health effects whilst addressing important research questions that enhance conservation management policy. In 2014…
Minimising seabird interactions with longline operations is a key objective of the management of fisheries in CCAMLR (see e.g. Conservation Measure CM 25-02 and 41-08). Longline fishing in the fishery for Patagonian toothfish (Dissostichus eleginoides) in Statistical Division 58.5.
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).
The use of molecular assays to assess the presence of species using environmental DNA (eDNA) and RNA (eRNA) as analytes has diversified as the field of environmental surveillance advances. These methods can be used, for example…
The Antarctic plateau provides the best terrestrial sites for infrared and sub-millimetre astronomy. In this paper we examine the relative importance of temperature…
CCAMLR Conservation Measure 25-02 requires Spanish-system longline vessels to attach 8.5 kg weights at 40 m intervals on longlines to minimise interactions with seabirds. The weights typically used are collections of rocks enclosed in netting bags.
Repeat summer hydrographic observations along … 140E are used to document significant changes in the … properties of the Ade´lie Land Bottom Water (ALBW) between the mid-1990s and 2002–2003. Water on the 28.35 … kgm3 neutral density surface cooled by 0.2C and … freshened by 0.
Although guidelines exist for approaches to Weddell seals (Leptonychotes weddellii) in … Antarctica, there has been no scientific assessment of the effectiveness of these guidelines in … minimising disturbance to the seals.
This study represents the first investigation into the feasibility of using remote sensing to map and monitor the vegetation of sub-Antarctic islands. There have previously been no studies using satellite technology to remotely sense vegetation change in the Antarctic or sub-Antarctic regions…
Abstract … Little effort has been devoted to differentiating between hydrocarbon losses through evaporation and biodegradation … in treatability studies of fuel-contaminated Antarctic soils. When natural attenuation is being considered as a treatment … option…
ABSTRACT: Foraging movements of Adélie penguins are constrained both by environmental conditions … (e.g. sea ice cover) and life history factors (e.g. regular offspring provisioning). We describe … within season changes in foraging range…
The Protocol on Environmental Protection to the Antarctic Treaty (the Madrid Protocol) introduces the requirement to plan and conduct activities to avoid or minimise degradation of the wilderness and aesthetic values of Antarctica.
An experiment was conducted on an autoline longline vessel to derive a sink rate, and line weighting regime, that would minimise the capture of albatrosses based on knowledge of line sink rates and albatross diving abilities. Sink rates of lines deployed into propeller turbulence…
