I'm interested in what the possibilities are for physics grads regarding masters studies, specifically for those not continuing with physics. I know that engineering is an option, but that's a bit vague. It's such a big field and I would like to specialise anyway (part of my reason for giving up physics is job security, so good-employment chances are also important). I like to travel and the idea of working outdoors and not in a lab really appeals! That's why I think survey work would suit me. So far I'v got - hydrography - petroleum geophysics but I'm not sure. Are there any other options like these two?
