Voices from Antarctica – Ep 1 Ice Flight


Our Changing World producer Alison Ballance dons her extreme cold weather clothing for an audio adventure to Antarctica – but as she soon discovers, it’s all very well to be dressed and ready to go, but there are a lot of factors that can get in the way of a visit to the frozen continent.

Our Changing World's Antarctic collection


Our Antarctic collection contains a treasure-trove of stories recorded in and about Antarctica.

From past climates to future climate scenarios, from microbes to marine megafauna, as well as ice and historic huts.

Check it out if you're in the mood for frozen science.

Cadmium - colour and quantum dots
Caesium - the time-keeper
Calcium - strength and beauty
Carbon - life and times of the King of Elements
Cerium - combustible and confusing
Chlorine - good for health, bad for health
Chromium - colourful and shiny
Cobalt - goblin of the periodic table

Platinum – another pricey precious metal
Plutonium – nuclear bombs & nuclear power
Polonium – few redeeming features
Potassium – a matter of life and death
Praseodymium – a long name but not many uses
Promethium – rare and unremarkable
Protactinium – a very dull chemical element

Radium – famous but not very useful
Radon – radioactive basement risk
Rhenium - has a number of claims to chemical fame
Rhodium – used in cars, drugs … & aftershave
Rubidium – expensive and not very useful
Ruthenium – a ‘sort’ of precious metal

Samarium – magnets for making & listening to music
Scandium – the scandal of the scandium cricket bat
Selenium – good reason to eat seafood & Brazil nuts
Silicon – a ubiquitous part of modern life
Silver – a popular noble metal
Sodium – a salt of the earth spectator
