From living beside a growing ice chasm, to signing up to live in Antarctica through dark Antarctic Winter - Jaskiran Nagi and Jonathan Witherstone are electronics engineers with a shared love of knowing how things work and being outdoors. 

Jas chats about his work at Halley Research Station and maintaining the seismic instruments on the ice shelf there, and Jonathan reveals the surprisingly low-tech secrets behind maintaining comms in the snow at Rothera Research Station.
