Andrew Hogg, of the Research School of Earth Sciences, has discovered that a temperature gradient across the Southern Ocean, combined with the Earth’s spin, also could power the Antarctic Circumpolar Current.

"Until I got to university, I didn’t know what area of science I wanted to specialise in, I just knew that I loved science," explains Nerilie Abram. "Earth science was my extra subject - but I quickly found out that it was exactly what I wanted to do. Discovering how the earth works is fascinating!"

One of the benefits of being a scientist is that sometimes you get to discover new things and if you’re lucky enough, you may even be able to get them named after you.

During my PhD I am trying to get some insights into early life on Earth.

I graduated at the bottom of the mid 1970’s mining boom and after a year of pushing to launch a career in geology, during which I worked on the 25th International Geological Congress in Sydney, and part-time for a geological exploration company in the Michelago area, I made the decision to try teaching.

After my undergraduate degree in geology in Sydney I worked in the minerals industry for 3 years as an exploration geologist.
