Cruising the Icebergs

Antarctica

Antarctica was an adventure in itself , but cruising the icebergs topped it off. Ummm well, the penguins were super amazing too. The zodiacs were lowered into the water and we all loaded up sitting on the edges.

My husband and I were in the lead boat…such fun…as the second in command of our ship the Fram was driving our zodiac and he was out for some fun. “This is my toy,” he said. It was an understatement to say, we did indeed have lots of fun.

We zoomed in and out and around, oohing and aahing  as we passed many different formations like the saw tooth above.

We were able to go close up and take a really good look.  As it was their summer, the ice was slowly melting and constantly changing shape

Oh look, there, some of our fellow cruisers. We had to wear total body suits to protect us in case we got dumped into the water. I don’t think that was on too many people’s minds as we had such amazing icebergs to look at.

Bridges had formed and were enticing to go through…but we did not for safety sake.

Just look at the wonderful blue colours, the reflection in the water  and the icicles.  There is a great accumulation of snow on the top of this one.

Ice caves and holes filled with fabulous blue colours.

This one is called royal icing because of it’s smooth finish like an English Christmas Cake iced with royal icing.

Michael Reichmann a scientist says, and I quote :

“The bluish streaks in some Icebergs are caused by the the refreezing of meltwater which fills crevasses formed in the glacier (that creates the Iceberg) as it creeps over land. In other cases, the crevasses or holes (full of air) turn a deep blue. We will explain why this happens below.

Old Icebergs go through hundreds of thousands of years of compression and sometimes ongoing thawing and refreezing of the ice. As you go deeper and deeper into a glacier, the weight of the ice and snow above increases dramatically. As this pressure increases, the air that was originally trapped by the falling snow is forced out. As this happens, the reflective surfaces of our “snowflakes” get “crunched together” and in some cases can completely disappear. Since most of the reflective surfaces within this kind of iceberg have been eliminated, light hitting this iceberg no longer “bounces” off of millions of tiny mirrors. Instead, light is forced to travel through the Iceberg and penetrate deep enough to either find some internal surface to reflect back from or penetrate all the way through the iceberg.”

So there you have it. The wonder of, and the reason behind those gorgeous blue icebergs.  Antarctica, you are so very special.
