In Antarctica, the sea ice normally forms in salt water during the winter, and normally, almost entirely melts again in the summer.
The land ice and shelf-ice in Antarctica is melting -causing more fresh water to mix with salt water in the surrounding seas.
Fresh water freezes at a higher temperature to salt water- hence why there is now more sea-ice in summer.
The GW cults remind of the memorable quote from the movies JAWS, ..."It proves that you wealthy college boys don't have the education enough to admit when you're wrong."
The whole premise is that it is a shelf of "hard" ice that has broken away from the Antarctica main ice BECAUSE of warmer temps.
Time will tell.
"The fast ice was partly in the area because of the huge iceberg, B09B. This broke away from the Antarctic continent in 2010, collided with and snapped off the extended part of the Mertz glacier, and then grounded itself in the entrance to Commonwealth Bay. Since then, the sea ice that would normally have formed and blown out to sea has instead been blocked by B09B and frozen into place.
Given the recent reorganisation of the ice around the Mertz glacier, glaciologists aboard the Shokalskiy think the ship might have become inadvertently caught in the formation of a new area of fast ice, which could stay in place for several years."
Sea ice has negligible salinity true. But sea water does not so when sea ice melts it changes the salinity of water. Really not that hard of a concept.
Let me be more blunt, since you failed to pick up on the point I was trying to get across to you.
Again, ice is ice, whether it be sea ice or ice formed from precipitation. Due to it's same melting point, it matters not it's origin. The mixing of this melted ice with the surrounding sea water may dilute the salinity of that water a fraction, raising that freeze point SLIGHTLY, but only at surface levels, because salt water is more dense (heavier) than the fresh water, so the slight change at the surface is not going to create the thick ice that keeps an ice breaking ship from chpping right through it! Or, even more bluntly .... you are being fed a BS STORY!!
The freezing point of sea water is 28.4 F. while fresh freezes at 32F. The antarctic temperatures are leaps and bounds lower ALL OF THE TIME, with a high of -16 F to a low of -80 F. The year long average is -49 F. Ocean temps and currents are the only thing that prevents the whole bottom of the earth from freezing solid, and triggering an ice age, devestating life on earth.
Read my lips physics boy .... warmer is better, which is why farmers plant in the spring, and not the fall.

I think we should all be able to agree tha ice melts at temps above 32 F. Yes?
Now tell me ... when has Antarctica experienced temperatures on land at above 32 F ?
Let me help you ... the answer is NEVER, EVER, EVER!!! The yearly HIGH there is still BELOW ZERO, -16 degrees F. So there is no melting of land ice due to global warming ... if any land ice melt off is actually occurring, then it would have to be geothermal ... under the continent, not on the surface.
Greenhouse effect deals with surface temps, not temps originating from the earth's core.
If you people would do a little more thinking for yourselves, and less believing what others are telling you to believe ... nobody would need to explain this to you!!!
