Antarctica Ice Shelf Is Breaking from the Inside OutMore bullshit. The water beneath the glacier is saltwater because the bottom of the glacier is below sea level.From your OP --- -
Looks as if the scientists have been a bit conservative once again.
Hell no.. They just got the source of "WARM WATERS" wrong. This is NOT likely the ocean running UPHILL for 50 miles. It's likely that "WARM WATER" is running DOWNHILL -- towards the footing. Just the direction that Newton predicted it would travel..
Your crack is showing ---- WAY dafuck inland dude. Not near the 700m deep sea footing.
Alternate hypothesis is building mass inland is causing the PIG to move. That's what glaciers do all day long.. You think all that creeping is supposed to go cleanly at the surface?
If Antarctica were not covered in ice, it would be a series of islands. That means much of the ice in the region is already under constant pressure from the ocean, as its movements dislodge the ice that covers the area between the land masses. Cracking is more likely to occur in the valleys located on the ice sheet, where the ocean is in closer contact with the ice, researchers found.
The currents off Antarctica are warmer and carry saltier water that encourages melting. The sea temperature is about 5 degrees Celsius, which is far warmer than the average surface temperature of minus 20 C. That causes a twofold vulnerability for the ice, because some of it is located underwater and because it is exposed to the warm sea around it.
Similar rifts have already been observed in Greenland, as the Arctic warms and ocean water flows along the bedrock, causing the ice to melt. The Pine Island Glacier and a similar-sized neighboring glacier are unique because they block ice flows from reaching the sea. That’s enough to keep about 10 percent of the ice sheet from toppling into the warmer water.
where is it written that massive flows are pristine and organized events that DON'T crack up occasionally? How long have we actively monitored MASSIVE ice flows in Antarctica?
As for the "warming" of the Southern Sea -- it AINT there. We've done this before. Graph below is a screen shot from when I plotted UAH satellite data of the southern ocean over (IIRC) a 30 year span.. If you're looking for LOCALIZED warm sea water --- I'd check the volcanic fissures under the WAIS first. Dontcha think? Certainly if the claim is 5degC water..
