Tanya Patrick, editor of CSIRO’s kids’ science magazine Scientriffic, travelled to Antarctica in January 2007 to find out the answers to these questions and more.
While in Antarctica, Tanya interviewed scientists working on many International Polar Year projects, from studying ancient atmosphere samples trapped in million-year-old ice cores to looking in frozen lakes for extremophiles – microorganisms that thrive in places where other creatures don’t dare venture. “I flew to Ace Lake, in the Vestfold Hills, which is the largest ice-free area in Antarctica. It was an amazing sight seeing the scientists hard at work in the middle of the frozen lake,” she says. She also learnt how to build an igloo, visited an Adelie penguin colony and flew over giant glaciers on exhilarating helicopter flights.
