My job in Antarctica (No, it wasn't all beer and photography) involved collecting core samples of the ancient sea floor, exposed on the lands surface in a place called Marine Plain. It was an absolute privilege to see this part of Antarctica. Marine Plain is a area of special significance, an ASPA (Antarctic Specially protected Area); throughout Australia's history of living and working in Antarctica, only 5 people before me had set foot on Marine Plain (that's pretty cool). We weren't able to camp within Marine Plain, so each day we had to walk 10km in to work, and 10km back.. This is Burton Lake, and our three person team had to traverse around the edge to get to marine Plain. The water never fully freezes in this harsh environment as it is nearly 19 times more salty then the water in Sydney harbour.
