In this week's Firstline science chat we look at the role Antarctica plays in determining global climate and how New Zealand's scientists are at the forefront of that research.
Also, we examine the research looking into the food requirements of top predators in the Ross Sea and the impact commercial fishing could have on them.
And what cutting edge research is being undertaken in Antarctica's Dry Valleys?
Steve Pointing from Auckland University of Technology's School of Applied Sciences explains – watch the video.
