Fire is generally portrayed as frightening and destructive by the media. Humans have increasingly been able to manage fire by improved detection ability and improved fire control methods. In the ...
NIWA scientist Dr Katja Riedel travels to Antarctica to collect 300-year-old ice samples. She studies the ice to learn how our atmosphere has changed over the centuries.
Scientists observe water in its different forms to develop explanations of how the world works.
Dr Katja Riedel of NIWA explains why she enjoys her research in Antarctica and what fascinates her about this place.
