- Kooyman said the site visits confirm what the photographic evidence appeared to show: ice conditions produced by the collisions of the giant bergs with the shoreline
- In the 1990s a berg the size of Oxfordshire broke off the Antarctic ice shelf and was widely hailed as proof of global warming.
- The bergs, driven towards the lake outlet by katabatic winds, become stranded as they move into shallower waters.
- Eventually the berg struck the glacier with only a glancing blow, nevertheless breaking off enough of the ice tongue that maps of the region needed redrawing.
- There are some antiseptic-blue overtones to it, too, and a whole spectrum of greens where the berg descends into the depths out of sight.
