Antarctic ice shelves melt from beneath where they contact the ocean, but how well do ocean models simulate this process? Building on several decades of model development, a recent model intercomparis...

A new study led by ACEAS PhD researcher Claire Yung from ANU introduces a correction to ocean models that could significantly improve global sea-level rise predictions from Antarctic ice shelf melt.

Abstract. Societal adaptation to rising sea levels requires robust projections of the Antarctic Ice Sheet's retreat, particularly due to ocean-driven basal melting of its fringing ice shelves. Recent ...

Abstract. Ocean-driven basal melting of Antarctic ice shelves is an important process that affects the Antarctic Ice Sheet, global climate and sea level. Basal melting is controlled by small-scale pro...

From unique wildlife to resilient microbes, world-changing climate dynamics to untapped biotechnological potential – four UNSW scientists outline what makes Antarctica a laboratory like no other.

The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.

The ability of ocean models with depth coordinates to form Antarctic Dense Shelf Water (DSW) depends on their surface vertical resolution Deeper surface cells shift the direction of surface Ekman...

News comes as research finds record lows of Antarctic sea ice had seen more icebergs splintering off ice shelves

Abstract. Antarctic sea ice plays many crucial roles in the physical environments and ecosystems of Antarctica and the Southern Ocean. In this study, we sy

The Antarctic Slope Current shields Antarctica from warm waters. But new research shows meltwater is speeding up the current, which could make it more unstable.

Antarctic ice melt to drastically alter the structure of key Antarctic current, new research finds Antarctica’s “last oceanic defence” could be transformed by the melting of the very ice it shields, a...

Potential funding cuts for NOAA and its research partners threaten irreparable harm not only to climate research but to American safety, competitiveness, and national security.

Revealing the drivers of phytoplankton growth, their role in carbon cycling, and dynamics between ocean, seafloor and ice shelves

Denman Glacier, how deep is your continental shelf? By Katharina Hochmuth The Denman Marine Voyage is not only the first dedicated marine science voyage on our new home the RSV Nuyina, but we are also...

Mysteries of colourful icebergs By Kaihe Yamazaki Antarctica’s icebergs are famous for their brilliant whites and blues from glacier ice (compacted snow turns blue as air bubbles are expelled), but a ...

Dismissed researchers were improving severe weather predictions

With the ability to transform any ship into a floating lab, the Hydrobox has the potential to revolutionise ocean research.

Australia's icebreaker is about to embark on one of its most important missions since coming into service more than three years ago.

Hundreds of polar researchers issue an emergency statement calling for urgent action to deal with the impacts of climate change in Antarctica.
