Shooting Under the Antarctic Ice

An amazing post from the WSJ photo journal describing shooting under the antarctic ice for the upcoming BBC series Frozen Planet. Being a nature photographer would be a dream come true but Im not sure that I could stand these conditions!

Shooting Under the Antarctic Ice:
For “Frozen Planet” director Chadden Hunter and cameraman Didier Noiret, the challenges of photographing emperor penguins rocketing through ice holes from the water below at high speeds were significant, but shooting them underwater was even more daunting. In order to show the penguins with the jet stream of bubbles behind them, they had to dive unthethered (a rope could get tangled with the camera) and film with a slow motion camera that they had never used underwater before. The only way to control buoyancy was to let air into the dry suit from the tank.

If anything went wrong, “you would just descend to the bottom of the ocean,” says Chadden. Fresh water moisture in the breathing tubes could freeze up and restrict airflow. The water clarity was so great that that it played tricks on their minds. “The specks in the water that you first thought were plankton would turn out to be meter-long penguins a hundred meters away, circling like spaceships as they prepared to jettison themselves out of the hole,” says Chadden. ‘You were mesmerized. Then suddenly you would check the depth gauge and realize you were hurtling down at a great speed and would frantically press the button to get air into the drysuit…. It was like space walking, untethered from the space station, while being circled by aliens.” The documentary “Frozen Planet” will premiere in the U.S. on Discovery Channel on March 18 at 8 p.m., and the companion book is available January 2012 from Firefly Books.

Those that have swum up from the depths are circling around the exit point, waiting for their heart rates to return to normal. They then jet-propel themselves upwards, leaving a rocket trail of bubbles in their wake as all the air is forced out of their feathers. With no limbs to pull themselves onto the ice, this is the only way to exit. But it means they can’t see what’s on the surface, and beak-breaking collisions with ice blocks can happen.

Visiting polar bears were a worry for the crews filming them. As much as they enjoyed seeing the bears at the window, the constant visits from bears led to insomnia.

Under the Ross Sea. Doug Anderson fixes his tripod upside down to the sea ice so he can film the growth of the strange ice-crystal formations.

In the confined space of a volcanic cave the only way cameraman Gavin Thurston could film was to use the video mode of a digital SLR camera. Careful lighting was crucuial to show the diamond-like glitter of the crystals. Day by day the crystals would change, melting if the temperature rose but reforming when it dropped.
