Antarctica Rising: Uplift Rate Suppresses Conventional Geology

by Brian Thomas, M.S. *

Land is not supposed to rise this fast. Generations of geologists have been trained to think in terms of slow and steady processes to explain Earth features. New results show that the continental crust underlying Antarctica is rising rapidly as parts of its massive ice sheet have been melting away. This unexpected bounce might help better position the timing of similar effects that occurred in northern North America near the close of the Ice Age.

Since 1995, entire ice shelves the size of cities have been falling from the Northern Antarctic Peninsula into the sea. The land below that ice has been moving up to elevations where only ice once lay.1

A European team used satellites to track Antarctica's up-and-down motion, publishing their results in Earth and Planetary Science Letters.2 A Newcastle University press release said, "the land in this region is actually rising at a phenomenal rate of 15mm a year—much greater than can be accounted for by the present-day elastic response alone."3 The team investigated reasons why it has been rising so quickly.

Their answer points to the mantle deep below the crust. Temperature or chemical composition differences could get mantle material—circulating 250 miles below the surface—flowing more smoothly than expected. Its viscosity, or resistance to flow, is somehow ten times lower there than other zones beneath Antarctica.

Could an expansion in the magma cause the ice sheet to slough off? I certainly don’t have enough info to say yes or no, but that was my first thought.

I think it’s the opposite that is happening, the ice sheet falling off removes weight and pressure on the crust, allowing the magma underneath to push it higher.

The cause of course is another one of those pesky man-made solar eruptions causing climate change,

Rising at 15mm per year, hmm, lets just round it off to 25mm per year, or about an inch per year.

That would put the Rocky Mountains in the 150,000 to 200,000 year old range.

The great pseudosciences of Creation Research and Global Warming have finally aligned!

(Sorry, but in seven days, God made a universe that genuinely LOOKS old. A little brusher-up in Christian philosophy might explain why.)

Ice shelves extend over water, not land.

That’s whaty I thought...is the rising of the lanb causing the sloughing...rather than the reverse.

One would think that heat would either cause...or be the result of...this “rising”.But even if I'm right there’d certainly be no connection between this heat and the alleged melting of nearby ice.

“The sky is falling!!!!”:

Global warming! Global warming!

It was 100 degrees here in Southern NM yesterday. Supposed to be 103 today. Obviously Global Warming!

One hundred degrees...in the desert...in the summer? My God,what next? Fog in San Francisco? Snow in Vermont? Tornadoes in Missouri?

Except this isn’t mountains building. It is rebound of the surface.

Basically what happened in the upper Midwest and great lakes region of US and Canada at the end of the last ice age. The crust sprang back up when the weight of the ice was removed.

Anything from the Institute For Creation Research requires corroboration from peer reviewed sources.

I agree. It’s called Post Glacial Rebound.

Scotland and the Scandinavian countries are still rising even though it’s around 10,000 years since the ice which covered them melted.

Rye England Hotel I stayed used to be seaside in 16 th century now one mile from Sea Coast..haha

Greenland in same century was completely submerged under water in 16th century If I recollect correctly!

Indeed but Rye, which used to be an important port on that coast, is now inland due to the bay it sat on silting up.

The northern part of the UK is gently rising as a result of post glacial rebound whilst the southern part, Rye included, is ‘sinking’.

I’m not aware of Greenland having been completely submerged in the 16th century, in fact I doubt it entirely. Do you have a link?

"the land in this region is actually rising at a phenomenal rate of 15mm a year"

The Rockies rise faster than that.

Whats meant, tho, with the statement that the uplift cant be attributed to “Present day elastic response alone”?

That reads to me that the uplift is more than just rebound, right? If so, it means that something underneath is actively pushing up, which could very well be driving the calving.

Of the top of my head, the Himalayas are rising .6 inches, net of erosion yearly. That just shows the the Indian plate is still pushing into the Eurasian plate. Since Antarctica is a single plate, is is likely regional deformation. That is, perhaps the ice load is greater in one area and less in another.

I was likely wrong and perhaps those who suggest magma intrusion may be very close.

"The east Antarctica has a stable Precambrian shield[3], while results of aeromagnetic surveys in the west Antarctica show the presence of large volumes of volcanic rock and associated subvolcanic intrusions, of the order of a million km3[24]. In the last million years, volcanism has renewed on at least four of the islands (Deception, Livingston, Greenwich, and King George), which is coincident with rifting and volcanism in the adjacent Bransfield basin[25]. Therefore, the west Antarctica (including the Antarctica peninsula) is much more active than the east.

the referenced study is here.
