VOICED: N.Z.'s lost penguin to head home on research ship

Happy Feet, an Emperor Penguin, was found stranded in New Zealand, far from his Antarctic home. After two months of rehabilitation at Wellington Zoo, he is ready to return to the wild. Despite criticism over the cost, the effort brought attention to penguin conservation. Happy Feet will be released into subantarctic waters and tracked via a device, allowing scientists and fans to follow his journey.

What preparations were made for the Emperor Penguin's release back into the wild?

What tracking method will be used to monitor the Emperor Penguin after his release?
