- Antarctica icebergs
Ice bergs are eroded by a combination of temperatures above freezing and the effects of wave action. Here in a fairly rough sea, waves are washing up the side of this berg to a point about 2 metres above sea level and will probably make two separate upright areas that are divided by the developing trough. We did for a short time consider trying to speed through the gap when it was awash in our small powerfully driven zodiac boat, but decided against it - probably for the best!
