Ice Brinicles- The Freezing Killer

Amazing Photos & Video of Ice Brinicles- The Freezing Killer

Ice Brinicles
A brinicle or an ice stalactite is a formation of sea ice that gets generated when extremely cold saline water is introduced in ocean water. During winter, the temperature above the sea is -20C, whereas, the temperature of the sea water is only -1.9C. Heat tends to flow from the warmer sea to the extremely cold air, resulting in the formation of ice pipes.

The salt in this freshly created ice is concentrated and then later gets pressured into the brine channels. It’s cold and salty traits; make it denser than the water beneath. It results in the sinking of brine in a descending trail freezing the seawater altogether. This process results in forming a delicate ice sheets that develops into what has been called a brinicle.

How Did Lemurs come to Rule Madagascar...?


On our recent cruise along the east coast of Africa, we went in search of the black lemur on the island of Nosy Be, Madagascar.  It turned out to be quite an expedition – including paddling our own dug-out pirogues and walking across hot sand and mud to the Lokobe Reserve.  Local guides led us through the bush and we were successful in getting close-up views of a beautiful pair of Black Lemurs.
The female Black Lemur is a beautiful Cinnamon color
I prepared guests onboard the ms Amsterdam with a lecture about the fascinating creatures of Madagascar, including Lemurs.  In Africa, Monkeys evolved 30 million years after the early lemurs, out-competing the lemur lineage and driving them to extinction.  But by then the island of Madagascar was already far out to sea, drifting away from the African continent.  Thus my punch line -- "monkeys missed the boat by 30 million years." (An apt comparison for an audience of cruisers!)
