Mighty Indeed

In one of the harshest places on Earth, three women from different generations chase a hidden and ephemeral world beneath the Antarctic sea ice. Dr Natalie Robinson leads a world-first expedition to McMurdo Sound, joined by microbiologist Jacqui Stuart on her first trip south. Mentoring them from afar is veteran sea ice physicist Professor Pat Langhorne.
