Master By Research - Distance learning

Hi all;

I am interested in Master by research in distance learning and I want to know what are the available options. My interests are in Geography, Earth and Environmental Sciences. I have a Bachelor level degree in geophysics (2008) with excellent academic record.
I came to know about UniSa (University of South africa). I want to know what are the other options. Also, if any body has previously studied from UniSa, it will be very helpful if he provides some more information and personal experience.

Best Regards

Irfan
