The Antarctic vortex of October–December 2020 was the strongest on record in the satellite era for the season in the mid- to lower stratosphere. However, it was poorly predicted by the Australian Bureau of Meteorology's operational seasonal climate forecast system of that time, ACCESS-S1…
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…
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…
An international workshop to investigate a potential use of ageing method for the Antarctic krill (Euphausia superba, Dana) based on growth band counts observed in krill eyestalks was held in August and November 2021.
The current krill management approach endorsed by CCAMLR will require systematic data collection on a variety of spatial and temporal scales for each of the three pillars of the plan: the biomass assessment, the Grym model, and the risk assessment layer.
An Advisory Committee Work Programme for the 2023 - 2025 triennium will be submitted to MoP7 in 2022. This is a draft of that work programme seeking comments and eventual endorsement from the Advisory Committee.
At the Third Meeting of the Advisory Committee (AC3), 129 species of Procellariformes were assessed using a number of categories in order to provide Parties with an approximate priority list of species that might be considered for nomination to Annex 1 of ACAP (AC3 Doc 18).
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.
Exploratory fishing for Antarctic toothfish (Dissostichus mawsoni) in East Antarctica (Divisions 58.4.1 and 58.4.2) began in 2003. Since 2017/18, exploratory fishing has been conducted under successive research plans by Australia, France, Japan, Republic of Korea and Spain. Here…
In 2015 the ATCM endorsed a report listing 204 Important Bird Areas (IBAs) across Antarctica and offshore islands south of 60o South. In doing so the ATCM adopted Resolution 5 (2015)…
This paper draws attention to the publication in the scientific journal Nature of the results of the Retrospective Analysis of Antarctic Tracking Data (RAATD), a project of the Scientific Committee on Antarctic Research (SCAR)…
Supporting Antarctic scientific investigation is the job of the national Antarctic programmes, the government entities charged with delivering their countries’ Antarctic research strategies. This requires sustained investment in people, innovative technologies, Antarctic infrastructures…
Cosmic rays are charged particles whose flux observed at Earth shows temporal variations related to space weather phenomena and may be an important tool to study them. The cosmic ray intensity recorded with ground-based detectors also shows temporal variations arising from atmospheric variations.
Evaluating the demographic trends of marine top predators is critical to understanding the processes involved in the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical complexity of operating in … Antarctica, especially during winter…
The diversity of parasites found on Nyctiphanes simplex and Nematoscelis difficilis … (Order Euphausiacea) was compared during 10 oceanographic cruises made off both coasts of the … Baja California peninsula, Mexico. We tested the hypothesis that N.
