What is iceberg grounding?

Icebergs ‘ground’ on the ocean floor when their keel is deeper than the water depth. They may become stuck until high tide floats them off, or if they are washed into a shallow area, until they melt sufficiently to float away.

  1. In a Svalbard fjord in early September we witnessed a small berg (approx 25 feet long) surfacing several hundred meters from a glacier and only 30 meters from our Zodiak. It was predominantly the color of green transliscent jade, not blue.

    Is this phenomenon common? have a name? Have a reason for the color?
