Ice Ice Baby



Thanks to Barry for this set of beauties!

"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."





"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.
Just look at how the wave froze in mid-air!!! "

An Antartic eclipse


Look at this amazing photo!

The Sun, the Moon, Antarctica, and two photographers all lined up in 2003 Antarctica during an unusual total eclipse of the Sun. Even given the extreme location, a group of enthusiastic eclipse chasers ventured near the bottom of the world to experience the surreal momentary disappearance of the Sun behind the Moon. One of the treasures collected was the above picture -- a composite of four separate images digitally combined to realistically simulate how the adaptive human eye saw the eclipse. As the image was taken, both the Moon and the Sun peaked together over an Antarctic ridge. In the sudden darkness, the magnificent corona of the Sun became visible around the Moon. Quite by accident, another photographer was caught in one of the images checking his video camera. Visible to his left are an equipment bag and a collapsible chair.
