An international team of researchers have sounded new alarm bells about the changing chemistry of the western region of the Arctic Ocean after discovering acidity levels increasing three to four times faster than ocean waters elsewhere.
Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 metres, could be more vulnerable to complete disintegration than previously thought.
This massive ice stream is already in a phase of fast retreat (a "collapse" when viewed on geological timescales) leading to widespread concern about exactly how much, or how fast, it may give up its ice to the ocean.
Whilst scientists have a good understanding of how the West Antarctic Ice Sheet is melting and contributing to sea level rise, far less was known about the East, until now.
The Australian Antarctic Division has moved swiftly to adjust its shipping plans for the 2022-23 season with icebreaker RSV Nuyina unlikely to be in service due to a delay in receiving spare parts.
NTNU researchers from AMOS, the Centre for Autonomous Marine Operations and Systems, used small satellites and subsea robots — and everything in between — to study marine life in Svalbard’s Kongsfjorden in a first-ever experiment in May.
The Navy’s sole icebreaker HMS Protector dropped in on 21 scientists who maintain the polar research station of Vernadsky in Antarctica to check on their welfare.
Marine life hitching a ride on ocean-crossing ships poses a threat to Antarctica’s pristine ecosystems, with the potential for invasive species to arrive from almost anywhere across the globe, say the authors of a new study.
