Time-Lapse Photos Show Dramatic Erosion of Alaska Coast

[dbackjon]

Time-lapse photography of crumbling Alaskan coastlines is helping scientists understand the "triple whammy" of forces eroding the local landscape: declining sea ice, warming ocean waters and more poundings by waves.

The erosion rates from these forces are greater than anything seen along the world's coastlines, with the coast midway between Alaska's Point Barrow and Prudhoe Bay falling into the ocean in the inland direction by up to one-third the length of a football field annually, scientists have found.

"This is pretty eye-popping," Robert Anderson of the University of Colorado at Boulder said here today at the annual meeting of the American Geophysical Union.

Time-lapse imagery and videos taken by Anderson and his team show how frozen blocks of silt and peat — that contain about 50 percent to 80 percent water ice – are toppled into the Beaufort Sea within a matter of days during the summer months as large waves and warm waters combine to attack the coast.

The dramatic erosion is created by the combination of three main factors: longer ice-free conditions in the summer months (which are lengthening by about two weeks per decade); warmer ocean waters that can melt more of the ice trapped in the coastal soils; and the widening of the gap between the coastline and the sea ice that occurs in the summer months, giving waves more room to batter 12-foot-high (3.5 meters) coastal bluffs

Naieve, you got anything more substantial? The Al Gore thing is getting old, isn't it?

[AZGrizFan]

An article about time-lapse photography and they only give ONE photo?

I don't recall bringing up AG before. When did I do that?

Yeah, that proves it! Global warming is a left-wing, hippy hoax on giant industry! Thanks for clearing it up Z.

It doesn't matter. Your cadre of like minded buffoons (Gil Dobie) use it all the time.

The sun comes up, must be human-caused global warming which merits state control and marxism.

The sun goes down, must be human-caused global warming which merits state control and marxism.

Well, given that the headline touted time lapse photography, I kind of assumed they'd actually SHOW the time-lapse photography. I guess we should just take them at their word?

Exactly.

The earth may be warming up. But we have/had nothing to do with it, and there is absoulutely nothing that we can/will do about it.

[dbackjon]

Absolutely false native and DJH. The evidence is overwhelming that man is affecting the climate.

Wow...the ocean is causing beaches to erode.

Never thought that would happen.

I agree man is probably affecting the climate, but the question is how much? I don't think the evidence is overwhelming that man is having a significant impact on the climate.

[Gil Dobie]

Of course man is affecting the climate, but why do the affects have to be considered catastrophic and negative by the Donks.

Change isn't always negative, but people tend to fear change, unless they are campaigning for BO.

Gil, we just know more about this shit than you do. Donks/Liberals live a more authentic or natural life than you conks. While you're jacking off on baseball cards and shitting on the environment, we're enjoying nature, hiking, you name it. We're closer to the issue on so many levels.

You did not become concerned about the environment till your nemesis Al Gore made a splash. Me and Dback have been concerned for decades.

No No Nanu

I have a Bachelors Degree in Wildlife Management, drove a 50 mph car in the 1980's/90's before it was cool to drive a high mileage vehicle. If I never road a bicycle again, I would have more miles than any of you "do as I say, not as I do algorian Donks" could ride the rest of your life. Taking a gas guzzling motorboat out on a lake to fish, and drinking beer from a styrofoam cooler isn't exactly enjoying the environment. Taking a canoe or kayak is more enjoyable and eco-friendly. Richard Nixon cleaned up America's highways, and yes, I was there walking the ditches in the 1970's, picking up Donk beer containers. The gang of hypocritical Donks jumped on the bandwagon because algore did.

You guys think people were up in arms while the grand canyon was being carved out by the Colorado River and other effects that water has on sediment? Or since Global Warming did people start concerning themselves more with basic physics and chemistry?

I didn't know that only donks had motorboats, drank beer and littered.
