You’ve got these beautiful clear glass-like pillars and right next to it, it’s really delicate. Look at in them, filament 1 is there. As the cave team explore deeper, each chamber 2 reveals ice crystals more strange and spectacular than the last. No one on the team imagined a single Antarctic mountain could house so many wonders.
Down at the foot of Mountain Erebus, a third crew, the dive team, plan to explore the volcano's /lower slopes, which extend beneath the frozen sea. On board is / underwater cameraman, Hue 3 Miller 4.
Problem is, we don’t actually know what’s under the ice here, so who knows, it’s a problem of adventure. Old-fashioned tools still work best, first a hand chisel 5 to create an opening, then a saw to widen the hole. Ice diving in the coldest waters on the planet should be taken extremely seriously.
This dive is going to be a lot of things. Warm, is not on that list. Insulated suits will keep them alive under the ice for only sixty minutes. Once a helicopter departs, there's no margin 6 for error.
The dive team begin to explore the lowest slopes of Erebus, discovering a hidden world rarely seen by humans. Patrolling the icy shores of the volcano are killer 7 whales, the most southernly in the world.
Tracking them from above is the orca team. They need a helicopter to get ahead of the whales and to land them on the fragile sea ice. Cameraman Jamie Mcpherson must pick his spot carefully. His aim is to get the cameras as close to the killer whales as possible without disturbing them. Yes, clear almost. He uses a film camera to capture the action in slow motion, as the orcas come right by. Even in the extreme cold, a film camera proves to be rugged 8 and reliable, provided there is enough film in the camera.
