Amazing striped icebergs (Snopes.com says "True")
Icebergs in the Antarctic area sometimes have stripes, formed by layers of snow that react to different conditions. Blue stripes are often created when a crevice in the ice sheet fills up with meltwater and freezes so quickly that no bubbles form. When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it can form a green stripe. Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea.
Below: The water froze the instant the wave broke through the ice. That's what it is like in Antarctica where it is the coldest weather in decades. Water freezes the instant it comes in contact with the air. The temperature of the water is already some degrees below freezing.

I agree ~ where are all the cherry blossoms? Mama has more time in the summer, right(?) and I'm dying to hear from her!!
Tory and Aleks, too... and CJB!
Awesome! It's like visiting the National Geographic channel on your blog. I love it! Those icebergs are so interesting looking.
Cool facts and photos. I'm sure Al Gore has an opinion about what is going to happen with the ice...
Those are some awesome pics, I would love to see that in person!!
