Understanding transport and transformation processes within the carbon cycle is essential to creating global carbon dioxide budgets and therefore also projections for global warming.
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.
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.
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.
The Arctic Ocean has been getting warmer since the beginning of the 20th century—decades earlier than records suggest—due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.
Sea ice in the coastal regions of the Arctic may be thinning up to twice as fast as previously thought, according to a new modelling study led by University College London (UCL) researchers.
