We’re on board the RSS Sir David Attenborough for the vessel’s first big science season in the Antarctic, since it launched in 2020. It’s crewed by scientists involved in Project Biopole, a 5-year mission attempting to better understand carbon cycle at the poles. Nadine Johnston, a microbiologist with the British Antarctic Survey, joins Inside Science to talk about her work on copepods; zooplankton that build up huge fat reserves over the spring and summer months, then hibernate at 3000m during winter, taking carbon with them which is then locked-up in the deep ocean for up to 600yrs! Her research is a world first in the Southern Ocean and could help improve global carbon modelling of the earth system.

Staying in the South Pole, neuroscientist John-Antoine Libourel, talks about his latest research into the surprising sleeping habits of chinstrap penguins.

And after weeks of intense earthquake activity, the volcano on the Reykjanes peninsula of south-west Iceland has erupted. Dr Evgenia Ilyinskaya, our go-to volcanologist, provides an update. Plus, a nod to the festive season, as composer and AI artist, LJ Rich, explains why Christmas music makes us feel all fuzzy.
