Orkney Passage Long Term Monitoring

The densest waters in the Atlantic overturning circulation, Antarctic Bottom Water (AABW), originate in the Weddell Sea, as Weddell Sea Deep Water. A large proportion is exported northward to the …


SO-WISE

We are constructing observationally-constrained estimates of the state of the Weddell Gyre, including associated ice shelves and sea ice Introduction In the 25 years between 1992 and 2017, ocean melting …


Modelling Movement of Antarctic Krill

The MMAK project is using state-of-the-art ocean-sea ice models to improve our understanding of processes that influence the distribution of krill in the South Orkney Islands region.




DynOPO

Dynamics of the Orkney Passage Outflow (DynOPO) is a collaboration between BAS, the University of Southampton and the National Oceanography Centre (NOC). The project aims to investigate the flow of …

Understanding Antarctic Bottom Water (AABW) and its affect on global ocean circulation.


Filchner Ice Shelf System, Antarctica

Understanding the contribution that polar ice sheets make to global sea-level rise is recognised internationally as urgent.  The mission of this five-year project is to capture new observations and data …


Underwater tsunamis created by glacier calving

23 November, 2022

Scientists on a research vessel in Antarctica watched the front of a glacier disintegrate and their measurements ‘went off the scale’. As well as witnessing disruptions on the ocean surface, …


New map of Southern Ocean floor

10 June, 2022

A new map of the seafloor of the Southern Ocean surrounding Antarctica provides the most accurate representation of this vast area to date. An international team of scientists, including several …

The debut mission involving the autonomous submarine Autosub Long Range – affectionately  known as Boaty McBoatface –  has for the first time shed light on a key process linking increasing …







Wind-blown Antarctic sea ice helps drive ocean circulation

27 June, 2016

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study published today in the journal Nature Geoscience (Monday 27 June) shows how that ice migration may be more important for the global ocean circulation than anyone realized.
