Photographer's Note

After spending an hour at the abandoned USAF base, we headed further up the Ikateq channel towards the Sermiligao fjord where we intended to turn north and travel to the snout (terminus) of the Knud Rasmussen glacier.

On the way we stopped to photograph some of the more interesting icebergs that had been calved from this glacier and the Karale glacier, which together were the sources of all the icebergs in these channels.

I particularly liked the shape of this 30-35 ft high iceberg (it’s a bit hard to judge how big an iceberg is when there are no other boats around to provide scale) which reminded me of those super cruisers or super cats that you see tied up in marinas in places like Monaco and Miami.

This particular iceberg has a number of water lines, and a very smooth surface, which suggests that much of what is above water now was previously underwater. When chunks of ice break off an iceberg, its centre of gravity changes and it turns in the water – sometimes as much as 180 degrees when a large part separates. Only one ninth of an iceberg is above water, so if a large section breaks off underwater, its shape and form can completely change in a matter of minutes. I saw one large iceberg (over 100 ft high) do a complete somersault in the Sermilik fjord, and it is a truly spectacular sight.

The iceberg pictured here has four distinct waterlines, suggesting that it has changed its form at least that many times since it was calved from one of the glaciers about 20 km to the north.
