Margaret Wallace
Hello, my name is Mags Wallace. I did an MESci in geophysics and Geology from Liverpool University, followed by a PhD in Physical Oceanography with the Open University and British Antarctic Survey. My research focused on ocean circulation on the west Antarctic Peninsula, with a particular emphasis on sea ice-ocean-atmosphere interaction. I then undertook a post-doctoral position researching the effect of sea ice and the polar light cycle on the behaviour of Arctic zooplankton. Although I am new to popular science writing, I have been writing for enjoyment since I was a child, and during my time working in research I have published papers in scientific journals on topics such as deep Earth structure, physical oceanography and biophysical oceanography. I no longer work in research but I maintain an active interest in science and I really like the idea of making it accessible to non-specialists. I hope to achieve this through sharing my fascination with the natural world with others.
