Potential seaways across West Antarctica [PDF]
, 2011 The West Antarctic ice sheet (WAIS) has long been considered vulnerable to rapid retreat and today parts are rapidly losing ice. Projection of future change in WAIS is, however, hampered by our poor understanding of past changes, especially during ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Overconfident sea ice forecasts pose a challenge in subseasonal prediction. To test a potential way to address this issue and account for sea ice model uncertainty, this article investigates a stochastically perturbed parametrisations (SPP) scheme for sea ice in a prototype CY49R2 configuration of the coupled IFS‐NEMO4‐SI3 system. The results show that

Application of HY-2B Satellite Data to Retrieve Snow Depth on Antarctic Sea Ice
Remote SensingSea ice and its surface snow are crucial components of the energy cycle and mass balance between the atmosphere and ocean, serving as sensitive indicators of climate change.

Journal of Field Robotics, EarlyView.ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly

Late Quaternary relative sea level change in the South Shetland Islands, Antarctica [PDF]
, 2010 Models have been inconsistent in their prediction of ice sheet volumes and extent over the Antarctic Peninsula and sub-Antarctic islands during the Last Glacial Maximum (LGM), and their contribution to sea level rise during subsequent deglaciation ...

Remote Sensing in Ecology and Conservation, EarlyView.Remote sensing can reveal population dynamics of Antarctic penguin colonies. In this study, we analyze emperor penguin (Aptenodytes forsteri) guano stains in remote sensing imagery and discover colony presence predating known records for 18 colonies across Antarctica.

Extended seasonal prediction of Antarctic sea ice concentration using ANTSIC-UNet [PDF]
The CryosphereAntarctic sea ice has experienced rapid change in recent years, with the total sea ice extent abruptly decreasing after a period of gradual increase from the late 1970s until 2014.

The Importance of Sea Ice to Antarctic Ice Shelves
Frontiers for Young MindsIce shelves are important because they act as a dam that regulates the amount of land ice that flows into the ocean. This means if Antarctica’s ice shelves were to break up, more ice would be melted into the ocean and global sea level would rise at a much faster rate.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean
Remote Sensing in Ecology and Conservation, EarlyView.The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Remote Sensing in Ecology and Conservation, EarlyView.Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...
