Satellite observing breakthrough for monitoring the movement of Antarctic dense water Ocean modelling researchers have discovered a reliable and long-term new method to capture the formation and export of dense water around the Antarctic coast. Dense water is formed as sea ice freezes, producing vast amounts of salty water that sinks. Being able to monitor

All part of the process: biology meets chemistry off an ice shelf By Delphine Lannuzel and Pauline Latour, with the Australian Antarctic Program Partnership (AAPP) During the Denman Marine Voyage, we’re combining biology and biogeochemistry to study phytoplankton either side of the Denman Glacier and the Shackleton Ice Shelf. We’re investigating why the west is

From East Antarctica to the world: outreach program goes global A young, talented and diverse group of Antarctic researchers working in the field alongside some of the sector’s research veterans was a hallmark of the Denman Marine Voyage (DMV). The two month-long voyage to the largely unexplored Denman Glacier and Shackleton Ice Shelf region of

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, according to a ground-breaking new study. Published in Geophysical Research Letters, the study predicts the melting of Antarctic ice through climate change will alter

Interview transcript – Australia’s Antarctic science funding: the crisis is now “The crisis is this year, it’s right now. That’s the conversation we’re trying to get across with our elected officials.” – ACEAS Director, Professor Matt King speaking with ABC Hobart’s David Reilly. *The following is a transcript of a radio interview on ABC Hobart’s
