“The key question is what’s driving the changes we’re seeing?”: Research voyage heads to Denman Glacier It’s RSV Nuyina‘s first dedicated marine science voyage and the first time scientists working with the Australian Antarctic Program have had the opportunity to study the Denman Glacier, in East Antarctica, from the sea. The Denman has retreated 5km in […]

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

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

Study of ancient collision zone reveals origins of enormous hidden mountain range in East Antarctica Australian researchers have discovered how a large mountain chain resembling the European Alps and buried deep below the East Antarctic ice sheet, grew and partly collapsed more than half a billion years ago. Formed by an ancient collision of two

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
