Life in the frozen oceans
Filmed in the Antarctic
“We might have expected that deep beneath the surface of the polar seas, the waters would be truly barren. But in fact we find life here in unimaginable abundance,” David Attenborough says in the opening moments of episode two.
Submersibles take us down beneath the ice of the Antarctic to another world, one rarely explored on TV. As Attenborough says, “Astonishingly in the deep sea, there is more life than anywhere else on earth.”

Filmed in the Gulf of Mexico
This spectacular volcanic hotspot was, unsurprisingly, a nightmare to film, according to producer Orla Doherty.
"It felt as if we had voyaged to another planet and we nicknamed the site ‘War of the Worlds,’" she says. "Suddenly, we were entirely surrounded by giant bubbles of methane, erupting from what had been an empty abyssal desert only minutes before."
She added, "We returned to ‘War of the Worlds’ twice more during our expedition. Both times, there was barely a puff coming from the methane volcano. We had been unbelievable lucky - the deep had given up one of its great secrets, but only the once."
