Lanternfish reveal how ocean warming impacts the twilight zone
A new study from the British Antarctic Survey shows how lanternfish, small bioluminescent fish, are likely to respond to the warming of the Southern Ocean.

Albatrosses in decline from fishing and environmental change
The populations of wandering, black-browed and grey-headed albatrosses have halved over the last 35 years on sub-antarctic Bird Island according to a new study published today (20 November) in the journal Proceedings of the National Academy of Sciences.

New Antarctic heat map reveals sub-ice hotspots
An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet. The map is published this week (Monday 13 November) in the journal Geophysical Research Letters.

'Scars' Left by Icebergs Record West Antarctic Ice Retreat
Thousands of marks on the Antarctic seafloor, caused by icebergs which broke free from glaciers more than ten thousand years ago, show how part of the Antarctic Ice Sheet retreated rapidly at the end of the last ice age as it balanced precariously on sloping ground and became unstable. Today, as the global climate continues…

Large iceberg breaks off Pine Island Glacier
Latest satellite images reveal a new 100-square-mile iceberg emerging from Antarctica’s Pine Island Glacier. The calving event did not come as a complete surprise, but is a troubling sign with regards to future sea level rise.

Arctic sea ice at minimum extent for 2017
Arctic sea ice extent has likely reached its minimum extent for the year, at 4.64 million square kilometers (1.79 million square miles) on September 13, 2017, according to a team of international scientists. The 2017 minimum is the eighth lowest in the 38-year satellite record. The Arctic sea ice minimum marks the day – typically…

More losers than winners for Southern Ocean marine life
A team at British Antarctic Survey (BAS) examined the potential distribution of over 900 species of shelf-dwelling marine invertebrates under a warming scenario produced by computer models. They conclude that, while some species in some areas will benefit, 79% of the species native to the region will lose out. This has important implications for future…

Impact of giant Antarctic iceberg – update on Larsen-C
The largest remaining ice shelf on the Antarctic Peninsula lost 10% of its area when an iceberg four times the size of London broke free earlier this month.Since the 12 July 2017 breakaway Dr Anna Hogg, from the University of Leeds, and Dr Hilmar Gudmundsson, from the British Antarctic Survey (BAS), have continued to track the iceberg…

Huge Antarctic iceberg finally breaks free
After months of ‘hanging by a thread’ a vast iceberg the size of Norfolk has finally broken off Antarctica’s Larsen C Ice Shelf. Around 30 metres of this 190m thick block of ice sits above the sea surface.

Signy Island is hottest place in the Antarctic
A World Meteorological Organization (WMO) committee of experts announces this week (Wed 1 March) new records for the highest temperatures recorded in the Antarctic Region. The results are part of continuing efforts to expand a database of extreme weather and climate conditions throughout the world.
