Heading for a spectacular looking berg off in the distance we caught sight Jade iceberg which are not that common and just amazing to see due to their jade like colour (this is a little more glacial blue than green). Ecstatic onlookers went off with the sighting and it was nothing short of spectacular so we circumnavigated it and looked on in awe of it as though looking upon a mythical creature.
Jade bergs form underneath glaciers that are flowing out onto the ocean. They are refrozen sea water that percolates into the underside of the glacier and refreeze in doing this all of the salt is pushed out of the sea water that it forms from. It only happens on a couple of glacial flows in Antarctica so is a real find and worth a mention.
It was a very cold afternoon out on the water but well worth a bit of discomfort!
