The temperature has cooled, the snow showers are falling as we transit through an area of icebergs, bergy bits and growlers. The question is, what is the difference? Well large, medium and small works but of course the answer is far more precise.
To be classified as an iceberg, there must be a height of at least 5 metres above sea level, be 29 – 50 metres thick and cover an area of at least 500 square metres. The bergy bit is a medium to large fragment of ice and the growler is a smaller fragment of ice, with less than 3 metres above sea level with an area of about 20 square metre.
Then there is the shape and sizes of each. Again, there is a technical answer, there are tabular and non-tabular shaped icebergs. The tabular has a flat top and steep sides and the non-tabular have different shapes, domes and spires. Whatever the type, they are a spectacular sight.
The view has been enjoyed by all today and there is a constant stream of "look at that" and for those that have been many times before, still marvel at their beauty.
