Antarctica is a well-established space analogue environment where expeditioners face challenges similar to those experienced in human spaceflight.
Antarctic Bottom Water (AABW) is the densest water mass in the world and drives the lower limb of the global thermohaline circulation. AABW is formed in only four regions around Antarctica and Cape Darnley, East Antarctica, is the most recently discovered formation region. Here…
Ocean-driven basal melt can thin and weaken ice shelves, reducing buttressing and causing sea level rise. However, the processes driving melt in ice shelf cavities are challenging to observe. Here we report float observations spanning the ocean cavity beneath Shackleton Ice Shelf.
Mass loss of the Antarctic ice sheet is largest in the Amundsen Sea Embayment, West Antarctica, due to basal melting by warm modified Circumpolar Deep Water (mCDW).
The long-held view that the East Antarctic margin is isolated from warm offshore waters has been challenged by recent observations showing incursions of warm modified Circumpolar Deep Water (mCDW) reaching several East Antarctic ice shelves. However…
Overview of past and future climate change in Australia's area of responsibility in Antarctica, sub-Antarctic islands and Southern Ocean, and impacts of Antarctic changes upon the Australian mainland.
US and Australian researchers are collaborating to study how extreme, isolated environments in Antarctica affect health, using this research to develop and test new mental and physical health technologies for astronauts on long-duration space missions.
The Australian Antarctic Program (AAP) serves as a unique Earth-based analog for space travel, using its extreme, isolated environments to conduct research that directly supports long-duration human spaceflight. Studies focus on the long-term effects of confinement and isolation on human health…
Australian Antarctic Space Analogue: A research project using the Antarctic environment to study the effects of isolation, confinement, and extreme conditions on human physiology and psychology, relevant to long-duration spaceflight. Medical Model:
One of the largest sectors of the Southern Ocean is the Indian Sector, which plays an important role in regulating the Earth's climate and supports a diverse ecosystem. To understand how climate change impacts the environment in this sector…
The advent of under-ice profiling float and biologging techniques has enabled year-round observation of the Southern Ocean and its Antarctic margin. These under-ice data are often overlooked in widely used oceanographic datasets…
Baleen whales are predominately summer visitors to Antarctic waters, where they feed on large swarms of zooplankton, primarily Antarctic Krill (Euphausia superba). Over 2 million whales were killed in Southern Hemisphere whaling operations in the 20th Century 1.
Individuals in isolated and extreme environments can experience debilitating side-effects including significant decreases in fat-free mass (FFM) from disuse and inadequate nutrition. The objective of this study was to determine the strengths and weaknesses of three-dimensional optical (3DO)…
The Southern Ocean is disproportionately important in its effect on the Earth system, impacting climatic, biogeochemical, and ecological systems, which makes recent observed changes to this system cause for global concern.
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. This record-shattering event saw numerous monthly temperature records being broken including a new all-time temperature record of -9.
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. In Part I, we assessed the meteorological drivers that generated an intense atmospheric river (AR)…
As we learn more about the importance of cetaceans in the Antarctic, including their populations' recovery and needs as krill and fish predators, it is increasingly clear that cetacean science is vital for informing ecosystem-based management.
