NASA: Ice Caps Overtake Glaciers as Biggest Contributors to Rising Seas
NASA: Ice Caps Overtake Glaciers as Biggest Contributors to Rising Seas
>From reuters, by David A Gabel
The news just seems to be getting worse and worse coming out of the Arctic and Antarctic. The melting of ice is not appearing to let up, and is in fact, getting faster. A new NASA-funded satellite study shows that the two biggest ice sheets on Earth - Greenland and Antarctica - are losing mass at an accelerating rate. This is the longest study ever conducted to analyze changing ice conditions at the poles, spanning nearly 20 years. Researchers concluded that the melting of ice caps has overtaken the melting of mountain glaciers to be the most dominant source of global sea level rise, much sooner than previous forecast models predicted.
Over the length of the study, the ice caps have lost an average combined mass of 475 gigatons per year (1 gigaton = 1 billion metric tons). Over the course of the study, that number has risen by 36.3 gigatons for each consecutive year on average. In comparison, the loss of mountain glaciers was estimated at 402 gigatons per year on average. However, the rate of acceleration for mountain glacier loss is three times smaller than that of the ice caps.
"That ice sheets will dominate future sea level rise is not surprising -- they hold a lot more ice mass than mountain glaciers," said lead author Eric Rignot, jointly of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and the University of California, Irvine. "What is surprising is this increased contribution by the ice sheets is already happening. If present trends continue, sea level is likely to be significantly higher than levels projected by the United Nations Intergovernmental Panel on Climate Change in 2007. Our study helps reduce uncertainties in near-term projections of sea level rise."
Over the next four decades, the researchers conclude that if ice sheets keep melting at their current rate, sea levels could rise by 15 centimeters (5.9 inches) by 2050. However, they caution that there are number of uncertainties remaining in accurately predicting future ice loss acceleration.
This study is published in the journal Geophysical Research Letters.

Shipwreck on Tristan de Cunha - Northern Rockhoppers endangered
I'm just now in port from a ridiculously amazing week shared with good friends and more humpback whales than I could have hoped for. I'll be sharing that story when I'm back in the office in a few days but for the moment, sorry, some rather nasty news. A 75300 tonne tanker (yes, that's 15 TIMES larger than our favorite Antarctica vessel, Polar Star, by weight!) carrying a load of soybeans ran aground in Tristan de Cunha a few days ago. She has now broken apart and is leaking her reported contents of 300,000 gallons of heavy marine oil and 15,000 gallons of diesel oil. Thanks, Jim, for alerting me.
This is a serious bummer for the penguins of the world. The endemic Northern Rockhopper resides there, as do Greater Shearwaters and an abundance of other seabirds. How a brand new tanker - commissioned in 2009 - could run aground on a well charted island, that is entirely beyond me.
The story, with photos: http://www.tristandc.com/newsmsoliva.php --- this is a chronological webpage, so the most recent news is at the bottom.

Antarctica melts while the House fiddles
If you are a voting American (like me), time to be embarrassed.
Just as NASA is finding that Antarctica and Greenland are losing ice faster than previously estimated --- yes, yet another revision upward where models are proving too conservative --- just as we have more evidence of climate change, we also have a news that the House of Representatives is using it's profound powers of scientific illiteracy to deny all evidence and prudence. Here in this space I normally refrain from the political but this is just stupid.
Choice lines:
"From 1992 to 2009, the two regions lost on average 36.3 billion tons more ice every year than the previous year"

And in the realm of protracted political tragedy, played out at the pace of a creeping glacier:
House Panel Votes to Strip E.P.A. of Power to Regulate Greenhouse Gases
"Many Republicans also argue that global warming is an unproven theory and that no action is needed to combat it, and they are backed by lobbies representing manufacturers; small businesses; agriculture; and the chemical, coal and oil industries; all of which have a big financial stake in hamstringing the E.P.A."
“We’ll never know what this president could have achieved...because he didn’t try.”

But hey, we can still have our fun, consequences aren't to be paid until well after the current political cycle (and after the death of most of these illiterates). Science damn it!

Have a nice day
Poison bait and snipers make South Georgia a happier place
It's rare that good in the world comes in the form of poison bait and snipers, but the universe works in strange ways.
Here's hoping... from the South Georgia Heritage Trust website:
Island’s recovery starts NOW! ~ We’re underway. The South Georgia Heritage Trust’s yellow helicopter G-TVAM began the clearance of rats from South Georgia today, March 1st 2011, by dropping the first load of bait on the Greene Peninsula.
They state today that the baiting of the Greene Peninsula is about 40% complete. That's one step in a long and worthy road. To all you former Cheeseman travelers who have supported this worthy cause, we salute you.
South Georgia Habitat Restoration Newsletter
And the South Georgia Association newsletter reports that the government of South Georgia will concurrently remove the reindeer.
http://www.sgisland.gs/index.php/(h)South_Georgia_News_and_Events
I look forward to the 2020 Cheesemans' Ecology Safaris Antarctic voyage where we get to enjoy breeding bird colonies on the main island of South Georgia where previously rats and reindeer kept the birds away!

Rivers, lakes and dynamics under the Antarctic ice sheets
I remember when Lake Vostok was discovered 15 years ago, so it's neat to see how this has evolved:
“In the last 15 years, we’ve gone from thinking there’s a little water under ice sheets, to thinking there are lakes the size of New Jersey under ice sheets, to thinking water can move around underneath ice sheets,” Dr. Bell said. “Now, we know that water can modify the basic structure of the ice sheets.”
This is the last frontier of geography, truly the last of the earth to be explored and uncovered.

A chilling image - yacht lost at sea in the Antarctic
Imagine this scene: you are sailing a small yacht in big seas, ripping winds of ~ 80 knots (90 mph / 150 kph), and there is ice in the water. At -10°C, every crashing wave sprays your rigging, which then freezes and makes your yacht top heavy and ever more prone to capsizing. There's no visibility, so you have no way of seeing much less avoiding ice. No safe anchorages exist within many hundreds of miles...
Whether it was ice or capsizing we will never know, but three were lost at sea and on my blog version of this posting, you can see the only trace that was left. I saw the image and felt a chill.... the raft is what tears off the deck and self inflates when a vessel goes down. (Image taken from the Sea Shepherd Conservancy vessel - after their great triumph over the season's Antarctic whaling - http://bit.ly/fYXiKe) Know those white barrel-like canisters mounted on the top deck of every ship? These self inflating rafts are what are inside of them.
Antarctica is beauty, glory incomparable, but it isn't humane, doesn't play on our terms.
For the full story (pasted below):

Antarctica: Empty raft found, still no Berserk
http://explorersweb.com/oceans/news.php?id=19973
(By Jon Amtrup) Berserk’s life raft has been found, but still no sign of the three people aboard the Norwegian sailing yacht. The raft was pretty beat up. Sea Shepherd searched the whole area and are convinced that there are no survivors. The skipper and one of the crew are racing towards the coast in two ATV's.
The life raft was discovered 45 miles north of the position where the distress signal was issued and is consistent with the drift and wind.
- The life raft was unoccupied, half filled with water, encrusted with ice and the canopy had been clearly torn half off by strong winds. Sea conditions at the time of the recovery were ideal – glassy waters, no swell, clear skies, and excellent visibility, writes Sea Shepherd in a press release. The Steve Irwin has searched the area for 24 hours with dinghy's, helicopter and the ship. Captain Paul Watson is convinced that the three people on board the Berserk are ”lost at sea sea and the recovery of their bodies is very unlikely.”
- All indications are that Berserk has sunk and that it sank very quickly. The conditions at the time were extremely high winds, extremely low temperatures, very heavy seas, and numerous and very dangerous growlers, says Watson on their homepage.
No other debris from the missing yacht has been found which could be a good sign for the crew. The raft could have been ripped off the boat during the bad weather and deployed in the water.
The three missing are two Norwegians Robert Skaanes (34), and Tom Gisle Bellika (36), and South-African Leonard J. Banks (32).
The Steve Irwin will continue the search Friday but that’s it. They are the only ship searching the area.
Meanwhile Berserk skipper Jarle Andhøy (33) and his crew Samuel Massie (18) are racing towards the McMurdo base on two belt driven ATV’s (All Terrain Vehicle).
The purpose of the expedition was according to Andhøy: "Berserk is under sail towards the South Pole to reconquer the pole 100 years after Roald Amundsen. The expedition started in fall 2009 from the top of the world (Northwest Passage ed.) and will be completed at the bottom by the “Pizzageneration” that are crewing the Berserk. The Berserk crew will try to follow in the footsteps of those who built Norway; war sailors, whale hunters and polar explorers. They all grew up in a much harder reality than our generation is living in today."
Jarle Andhøy and crew sailed down the west coast of America and over to New Zealand before setting off to the Ross Sea in Antarctica. Once there they reassembled the two belt driven ATV’s they had stored on board during the crossing. The plan was that Andhøy and Massie should drive to the South Pole, but they didn’t get far before the news about the missing Berserk reached them.
About charter yacht Berserk
Skipper Jarle Andhøy has been to Antarctica before, then in a 27-foot sailing boat. A high profile sailor in Norway, Andhøy has appeared on several TV shows and in the news. He was fined and sentenced in Norway for trying to ”talk to the Polar Bears” on Svalbard.
Accused of smuggling a crew member who had been sent out of the country on charges of being a Hells Angel, on his last trip through the Northwest Passage Canadian authorities cuffed Jarle Andhøy and flew him back home to Norway.
