Hello! 👋
We're the UK's polar research institute. We do climate and ecosystems science in Earth's frozen places, because changes there affect all of us.
As we say at British Antarctic Survey: what happens in Antarctica doesn't stay in Antarctica ⬇️

Signy Research Station is open for the season! 🎉
This team in the South Orkney Islands research seabirds and terrestrial ecology.
They were dropped off by RRS Sir David Attenborough - along with a band of helpers who cleared the snow, hauled in cargo, and helped bring power and water online 💙

Ever wondered what it takes to stay warm in Antarctica? 🧣🧤
In this episode of Iceworld, host Nadia Frontier talks to Emma Pearce about exactly that.
Bonus points if you can tell us how many layers you heard Emma mention!

Halley Research Station is open for business!
After a stop at Neumayer, serenaded with a horn farewell, the team reached Halley - only to find one door had reinvented itself as a wall… a wall of snow.
They’re melting it in tea urns for water and slowly getting the station ready for the season.
