New NASA satellite study reveals melting of Alaskan glaciers

A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years.

_______
Geophysicist Scott Luthcke of NASA's Goddard Space Flight Center, Greenbelt, Md., and colleagues knew from well-documented research that changes in the cryosphere glaciers, ice caps, and other parts of the globe covered year-round by ice -- are a key source of most global sea level rise.

Melting ice will also bring changes to freshwater resources and wildlife habitat. Knowing that such ice-covered areas are difficult to observe consistently, the team worked to develop a satellite-based method that could accurately quantify glacial mass changes across seasons and years, and even discern whether individual glacier regions are growing or shrinking.

The study's authors found that the annual ice mass lost from glaciers in the Gulf of Alaska has been 84 gigatons annually, about five times the average annual flow of the Colorado River through the Grand Canyon and equal to the entire amount of water in the Chesapeake Bay.

"The Gulf of Alaska region is 20 times smaller than the ice-covered area of Greenland, yet it contributes nearly half as much freshwater melt as Greenland and accounts for about 15 percent of present-day global sea level rise stemming from melting ice," said Luthcke, lead author of the study which will appear this week in the Journal of Glaciology. "Considering that the Gulf of Alaska makes such a disproportionate contribution, it is vital that we know more about the nature of glacial change there."

Luthcke and colleagues found a way to remotely measure the "mass balance" of a glacier; that is, the net annual difference between ice accumulation and ice loss. Past measurements of glacial mass balance in remote mountain ranges have been sparse or imprecise. Ground-based sensors can provide long-term data, but such data points are scattered due to the inaccessibility of many remote mountain ranges. Altimeters aboard aircraft can measure changes in the height of glaciers, but the sampling is sporadic because flights are relatively infrequent.

Glaciers in the coastal environments on the edge of the Arctic or Antarctic shed and gain mass rapidly, a high mass turnover that is particularly sensitive to climate change. Warming seas can accelerate the motion of tidewater glaciers, and melt water on glacial surfaces can flow to the floors of glaciers and serve as a lubricant as the ice slides toward the sea. The subsequent addition of freshwater to the ocean contributes to one of two sources of global sea level rise; "eustatic" rise resulting from melted ice in the form of freshwater, with the other source set off by "thermal expansion," sea level rise that occurs due to warming ocean temperatures.

The Goddard-led research team developed a new data analysis technique for NASA's Gravity Recovery and Climate Experiment (GRACE) mission. GRACE is made up of twin satellites that orbit Earth about 137 miles apart and 300 miles above Earth's surface. The positions of the two satellites change in response to variations in Earth's gravity field, which is stronger or weaker depending on the land or ice mass that they are flying over. Microwave ranging systems measure the distance between the two satellites down to the width of a human hair, so by measuring the change in the distance between the satellites over time, researchers can essentially "weigh" the changes in Gulf of Alaska glaciers.

Massive fraud in Alaskan Election

Shannyn Moore:

Something stinks. Not just an ordinary low tide smell. Not like something you'd blame on the dog. It smells like an infection. For me to plug my nose, I'd have to overlook some curious facts.

In Alaska, more people voted for George W. Bush in 2004 than for Sarah Palin on Tuesday despite an identical 61-36 margin of victory. Yes. Only four years ago 54,304 Alaskans got off their sofas and voted for Bush, but decided to sit home and not vote for Palin in 2008. In turn, I have to ignore the 30,520 Alaskans who felt progressive enough in 2004 to vote for John Kerry, but weren't inspired to vote for Barack Obama. I would have to glance past the 1,700% increase in the Democratic caucus in February, the 20,991 newly registered voters, and the three largest political rallies in Alaska's history. I would also have to forget the people I stood in a long line with to early vote. It would be helpful not to know every other presidential election since Alaska began keeping records has had a larger turn out than the one we just had with our own Governor on the ticket. Try not to remember 12.4% more Alaskans showed up for the August primary as compared to four years ago, before the Palin nomination. Don't think about the Lower 49's record voter turn out this year either. Try to delete the memory file, though difficult, that 80% of us approved of Sarah Palin just two months ago.

Something stinks. You don't care? Obama won. Yes. He. Did! Free at Last! Wait. Democracy demands all of the votes be counted...if you can find them.

In the balance hangs the fate of Alaska's Senate and House seats. We still don't know if we have elected the now convicted felon Ted Stevens, or Anchorage Mayor Mark Begich. We still don't know if Don Young and his million dollar legal problems will defeat former State Representative Ethan Berkowitz and his dreams of Washington DC. Alaska hasn't had Democrat representation in Congress since Mike Gravel lost his senate seat in 1980.

Four years ago, 313,592 out of 474,740 registered voters in Alaska participated in the election-a 66% turnout. Taking into account 49,000 outstanding ballots, on Tuesday 272,633 out of 495,731 registered Alaskans showed up at the polls; a turnout of 54.9%. That's a decrease of more than 11% in voter turnout even though passions ran high for and against Barack Obama, as well as for and against Sarah Palin! This year, early voters set a new record. As of last Thursday, with 4 days left to vote early, 15,000 Alaskans showed up-shattering the old record set in 2004 by 28%! Consider the most popular governor in history-and now the most polarizing-was on the Republican ticket. Consider the historic nature of this race; the first African American presidential candidate EVER! The second woman to ever make a presidential ticket; and she's one of our own. Despite that, we're supposed to believe that overall participation DECREASED by 11%. Not only that, but this historic election both nationally and for Alaska HAD THE LOWEST ALASKA TURNOUT FOR A PRESIDENTIAL RACE EVER!!! That makes sense. REALLY??? Something stinks.

But wait, there's more...
