Description
Icebergs at St. Anthony Newfoundland. Iceberg ice is pure fresh water. The ice is just highly compacted snow particles; a condensed water vapour that fell from the earth's atmosphere thousands of years ago. The only minute impurities that may be in the ice would come from dust particles created from volcanic activity many centuries ago. It is unlikely to find any pollutants in it. Depending on how dense the ice is, there might be air bubbles trapped inside. The air bubbles give the iceberg its characteristic white appearance because of its reflective property of white light. Sections of icebergs with no air bubbles have a blue appearance. Some icebergs will even have streaks of blue on them. This is caused by bubble free melt water refreezing in the cracks or crevices of the glacier as it crept to the coast.
