“The key question is what’s driving the changes we’re seeing?”: Research voyage heads to Denman Glacier

“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

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

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
