A University of Canterbury scientist is using Kiwi technology in her Antarctic research to capture fascinating footage of life beneath the surface in McMurdo Sound.

This year, as part of her research into the Ross Sea region Marine Protected Area, Gateway Antarctica scientist Dr. Regina Eisert partnered with Boxfish Research to study Type-C killer whales with a new kind of remotely operated vehicle (ROV).

Footage - Snippet - Hours - Season - Adélie

The stunning footage is just a snippet of what was recorded during 21 hours underwater this season. It includes, Adélie penguins, whales, Weddell seals, bright red octopus and a glowing ctenophore.

A University of Canterbury marine mammal expert, Dr. Eisert says the technology is a game changer for marine science, being safer and having a wider scope than scuba divers.

View - Marine - Animals - Penguins - Seals

"Before this, I feel that my view of marine animals was quite biased, we would observe penguins waddling along and seals sleeping on the ice and whales on the surface, but they spend most of their lives in the water and this is the important stuff to see.

"We got confirmation of the overlap between penguins and Type-C killer whales, the ROV captured unconcerned penguins freely entering and exiting the water in the presence of theses whales, and being ignored by them" she says.

Boxfish - ROV - Dives - Hours - Footage

The Boxfish ROV carried out 15 dives, gathered 21 hours of footage and reached depths of 210 metres this season.
