Icebergs are chunks of ice that have calved off glaciers and ice shelves. They vary in size from small to large enough to sink a ship. The Titanic, for example.
New icebergs are white while the older ones are blue or sometimes green. An iceberg comprises fresh snow and compressed ice. The light hits the iceberg particles and bubbles and is bent and scattered. If there are lots of bubbles, all the light scatters before it gets absorbed. If there are no or few bubbles, the red light gets absorbed and the blue light escapes the iceberg, making us see a blue iceberg.
During our time in Antarctica, we saw lots of icebergs, some of which dwarfed our ship. We zipped around some of the icebergs in zodiacs to get up-close views of them. The blue ones were my favorites.
Le Soleal, our ship, is dwarfed by this beautiful iceberg, and they can be much bigger!
A beautiful blue iceberg.
We did a zodiac trip around the icebergs and checked out the wildlife and birds that lazed on the different icebergs.
Another blue iceberg.

We finished our zodiac tour around the icebergs with a glass of French champagne. The perfect end!
