Denmark Strait. In Iceland it's called the Greenland Sound which makes more sense to me given its location.
The usual route for this voyage is to head west to go direct to Kangerlussuaq fjord (highlighted as red square below) but at the time the latest ice map below showed rather a lot of ice in that direction so we headed north instead:
Even with this more northerly route we did see ice, the encounters made more "interesting" with quite a bit of fog:
It took another night to get there but when came on deck for my watch saw the most amazing view of a mountainous icy landscape, just as promised.
We had arrived in Greenland...
