Massive iceberg that dwarfs Manhattan being watched closely by scientists

Massive Iceberg Six Times The Size Of Manhattan Breaks Off Antarctica


A giant glacier the size of Guam that broke off Antarctica isn't worrying scientists as much as it's amazing them.

The giant block of ice is six times the size of Manhattan, covering 225 square miles, and it's heading into the open sea. It broke off from the Pine Island Glacier in the Amundsen Sea last year and NASA officials have been watching the icy island ever since.

But scientists have kept an eye on the Pine Island Glacier for two decades ... because it's been melting rapidly - at almost 3 inches per day - due to currents of warm water flowing underneath it. Experts believe it could be an important contributor to rising sea levels.

However, one scientist told the Associated Press it's normal for icebergs to split off from glaciers. Fortunately, they say this particular block, which is more than 1,600 feet thick, doesn't put shipping traffic or sea levels at risk.

The team that's been tracking it says it will bring them new information about local ocean currents. The iceberg is expected to drift into the Southern Ocean.

The size of Guam? Somewhere, Congressman Johnson of Georgia is wondering if the iceberg will capsize!

He died many moons ago.

Noah would be no help with a floating chunk of ice, he would be a target. He helps with liquid ice raining down!

is the iceburg a salt water mixture or is it fresh water ice?

Can't freeze salt water it's all fresh water.

Water is one of the few liquids that expand when frozen. When icebergs which are made from fresh water melt there will be a slight hardly measureable increase in sea level.

This is true.

So, I guess when you put ice in a glass with water and the ice melts then the water runs over the top. This is idiotic. The ice is already in the ocean. the sea levels will not rise.

Tell that to the displaced people who no longer have an island to live on off Malaysia. Go visit some of the Florida beachfronts, and be amazed at the amount of water that is pumped daily to forestall the rising sea levels.

It must be an awesome sight to see this massive chunck of ice floating along in the Ocean. It makes me realize how vast the Ocean is!

If the ice slips off land the sea will rise, if it is floating on the water there will be no rise; as ice slips of land there is going to be a 2 to 4 foot rise in sea water in the next one hundred years, pretty much causing catastrophes on the coasts of countries, especially when storms occur, just as what happened in NY and NJ. Moreover, as ice melts it is releasing large amounts of frozen methane under these caps that is more toxic than CO2, pushing the limits of carbon dioxide to levels unsustainable for mankind. Playing with mother nature has its repercussions.

Put a motor on it and sail it to California and sell it!
