The first results from a project that uses satellites to track thousands of penguins as they waddle across Antarctica have been published.
By studying the movement of Adélie penguins, scientists hope to better understand whether conservation efforts on the continent are effective.
A small team from New Zealand played a part in analysing the data returned by the tracking program, which involved more than 70 scientists over 25 years.
Dean Anderson is a researcher at Manaaki Whenua - Landcare Research.
He speaks to Corin Dann.
