The Belgica 121 expedition to the Western Antarctic Peninsula: a high resolution biodiversity census

Bruno Danis
This dataset pertains to the outputs of the Belgica 121 (B121) expedition, which aim was to explore the surroundings of the Gerlache Strait (Western Antarctic Peninsula) and to carry out a detailed biodiversity census focusing on intertidal and shallow areas using both classic descriptive marine ecology methods as well as state-of- the art techniques (habitat mapping, genetics, trophic ecology). This dataset will offer access to the raw data on biodiversity occurrences, obtained using a range...

Antarctic krill and its fishery: current status and challenges

So Kawaguchi, Bettina Meyer, Jack Conroy, Haiting Zhang & Emilce Florencia Rombolá
Antarctic krill is a large, long-lived pelagic crustacean that is widely distributed around Antarctica and is among the most abundant wild animal species on Earth by biomass. Krill form dense swarms, are the main food source for many predators, and play important roles in biogeochemical cycles. However, crucial gaps remain in our understanding of krill population dynamics. Resolving these uncertainties will be fundamental to improving management if the fishery targeting this species is to expand...

Antarctic Sea Ice #3: Trends and Future Projections

Kyle Clem, Robert Massom, SHARON STAMMERJOHN & Phillip Reid
Since reliable and continuous satellite records began in 1979, there have been strong regionally- and seasonally-varying patterns of change and variability in sea-ice extent around Antarctica – in contrast to a largely uniform loss of sea ice across the Arctic. Notably, the region west of the Antarctic Peninsula to the eastern Ross Sea has experienced significant sea ice loss in concert with a strengthening of the Amundsen Sea Low and increased warm northerly winds. On...

Antarctic Sea Ice #2: Biological Importance

Kyle Clem, Robert Massom, SHARON STAMMERJOHN & Phillip Reid
Looking to the future, sea-ice coverage is predicted to significantly decrease by the end of this century in response to anthropogenic warming (see Antarctic Sea Ice #3), leading to significant reductions in ice- associated primary production and sea ice-dependent species – including Antarctic krill, Antarctic Silverfish, Adélie and Emperor penguins, Weddell and other pack-ice seals, and southern minke and other whale species.

Southern elephant seals (Mirounga leonina L.) in the Antarctic Treaty Area

Marthán Bester, Horst Bornemann, Gustavo A. Daneri & John van den Hoff
Despite the wholesale slaughter of southern elephant seals for the commercial extraction of blubber-oil during the mid and late 1800’s, their populations have persisted at almost all historical breeding locations There are presently an estimated 749,000 southern elephant seals in the Southern Ocean, about 2% (14,500) of which live permanently in the Antarctic Treaty Area south of 60º South Although these southernmost permanent breeding populations are relatively small, a large (yet to be determined) proportion...

Ten scientific messages on risks and opportunities for life in the Antarctic

Julian Gutt, Enrique Isla, José C. Xavier, Byron Adams, In-Young Ahn, Claudia Colesie, Vonda Cummings, Huw Griffiths, Ian D. Hogg, Trevor McIntyre, Klaus Martin Meiners, David Pearce, Lloyd Peck, Dieter Piepenburg, Ryan Reisinger, Grace Saba, Irene Schloss, Camila Signori, Craig Smith, Marino Vacchi, Cinzia Verde, Diana H. Wall & C.-H. Christina Cheng
Initiated by the SCAR scientific research programme “Antarctic Thresholds – Ecosystem Resilience and Adaptation” (AnT-ERA, 2013-2021), 26 experts synthesized knowledge on impacts and risks of climate-change on biological processes and ecosystem functions in the Antarctic.

The warming of the Southern Ocean and its significance

Sarah Gille, Michael Meredith, Jean baptiste SALLEE & Sunke Schmidtko
Warming of the Southern Ocean has implications for the climate system as a whole. This is because the presence of warmer water at the periphery of the Antarctic continent can contribute to ice sheet melt and consequent sea level rise, and also because transfer of heat from the atmosphere to the ocean has long-term consequences for ocean circulation and for the climate system as a whole.

Antarctic Penguin Biogeography Project: Database of abundance and distribution for the Ad?lie, chinstrap, gentoo, emperor, macaroni, and king penguin south of 60 S

Christian Che-Castaldo, Grant Humphries & Heather Lynch
The Antarctic Penguin Biogeography Project is an effort to collate all known information about the distribution and abundance of Antarctic penguins through time and to make such data available to the scientific and management community. The core data product involves a series of structured tables with information on known breeding sites and surveys conducted at those sites from the earliest days of Antarctic exploration through to the present. This database, which is continuously updated as...

Marine Noise in the Southern Ocean

Christine Erbe, Douglas Nowacek, Rachel Przeslawski & Daniel Costa
Marine noise is a form of ocean pollution that may affect fauna ranging from tiny zooplankton to enormous whales. It may interfere with their acoustic sensing of the ocean environment and communication; disrupt behaviour and displace animals; unbalance energy demand and uptake; in extreme cases, cause injury and trauma; and ultimately impact health and survival. The Southern Ocean is not immune to marine noise and its impacts; however, very few studies on bioacoustic impacts have...

Antarctic Sea Ice #1: Physical Role and Function

Kyle Clem, Robert Massom, SHARON STAMMERJOHN & Phillip Reid
Improved knowledge of Antarctic sea ice characteristics and ice-ocean-atmosphere-biosphere processes, interactions, and feedbacks is required to develop and improve Earth System models. Such knowledge is crucial to reducing current uncertainties in those models and to improve confidence in projections of the Antarctic sea-ice system over the coming decades and beyond (see Antarctic Sea Ice #3), including its impacts and coupled feedbacks. Improved sea-ice forecasting capability is also required to support safe and efficient shipping and...
