Iceberg six times the size of Manhattan

10 posts in this topic

Scientists are monitoring one of the largest icebergs in existence, after it broke off from an Antarctic glacier and began to head into the open ocean.

The iceberg covers about 255 square miles, making it roughly six times the size of Manhattan – and is up to 500 meters thick.

Here's an interesting video of B-31 breaking and drifting off:

Oki doki - um Southerner here - Melbournite, would very much like to know exactly where the scientists imagine this ice-berg might be heading ..... :unsure2:

There is increasing evidence that glaciers around the Antarctic Peninsula are shrinking and receding. Alison Cook found that 87% of the glaciers around the Antarctic Peninsula are receding27,28. Other workers have found evidence ofglacier recession and a measureable sea-level contribution29. There is evidence of widespread glacier recession around the northern Antarctic Peninsula21,30. Land-terminating glaciers in this region are shrinking particularly rapidly31, which is significant, as their mass balance is more directly controlled by temperature and precipitation, compared with marine-terminating glaciers, which respond non-linearly to climate forcing.

would worry if i had a house on the nearest sea front.

It's kind of scary having that float around until it melts.

At the current rate of population growth we're going to need the land under the cap at Antartica to live. The current coasts will be gone, replaced by new further inland ones. Some islands that are currently inhabited may be completely under water. Who knows there may be lots of oil and other essential items we humans need. May even find a buried space craft or two. I still think the human race is someone science project. Instead of an Ant Farm we have a People Farm.

I'd be interested to see how far this can get if it takes a year to melt. Shipping lanes are one thig, but the real danger large icebergs have is to offshore oil rigs. One that big would be difficult (impossible?) to wrangle onto a new course.

This is one big Ice-Cube. A shame it can't be used for something positive instead of just melting away into nothing. Seems like a(n) iceberg of that magnitude could really help drought stricken areas. (I know it would cost a shitload to pull it off)

That could be easily afforded If we diverted some cash away from our relentless pursuit of new and better ways to blow stuff up.

Can I now say:I was frozen today?

An iceberg floating in the ocean will not cause any rise in sea level because the total weight has already been imposed on the ocean level. The density of ice is less than water which is why ice floats. the total weight of ice is the same when melted as an equivalent weight of water..

To illustrate this just fill a glass with ice cubes and water then let them melt the level of the water in the glass will not change

The only time that ice will change the sea level is when the ice comes off of solid ground as in the ice cap of Greenland.
