north pole sea ice

Espérons que la glace se maintiendra beaucoup mieux que celle de l'an passé !

Ça semble très légèrement mieux cette année, mais la baie James était encore prise en revanche le 07 mai 2007...

Ce n'est pas pour être impoli où quoi que ce soit, car soit dit en passant je suis très interressé par le Pôle Nord, je ne comprends pas le but de tes interventions. Les images sont tous les mêmes et aucun texte n'accompagne celles-ci...Dans chaque image on voit les 2 mêmes pôteaux. En tout cas, au moins accompagné tes images d'un peu de contenu, ça serait apprécié :P

[dann17]

C'est vrai que tes images sont très intéressantes car on ne les trouve nulle part. Et le fait de voir "en direct" le temps qu'il fait au pôle Nord, avec les conditions météo (température, humidité, pression) c'est vraiment sympa ! Continue comme ça Iceberg...

 

Mais oui peut-être pourrais-tu nous donner d'autres indications (par toi-même) puisque tu as l'air de bien t'intéresser à ce coin particulier du monde...

 

Il sera intéressant d'ailleurs d'observer les conditions météo en plein été et début d'automne lorsque la banquise sera la plus fine...

Et ce serait formidable d'avoir un suivi régulier de l'épaisseur de la glace en ce point (pôle Nord)...

 

Le pourrais-tu donc ?

 

Merci,

En tout cas, j'aime bien l'image du satellite. On dirait une bulle prête a péter

 

Et j'avoue, en toute amitié, que les autres images en série m'ont laissé....froid.

Bonjour

 

Est-ce qu'un connaisseur ici a des statistiques, des informations ou des analyses sur la banquise arctique en ce début d'été?

 

Il semble que l'on se dirige vers un tristre nouveau record selon l'auteur du site climat-evolution...

ICE UPDATE JUNE 2008.

 

THIS YEARS ICE DEPTH AND TOTAL ICE SURFACE IS 25% GREATER THEN LAST YEAR JUNE 2007.WINDS ALOFT ARE NORMAL AND TOTAL SUNSHINE TO DATE IS 50 % LESS THEN LAST YEAR AT THIS TIME.THE REAL TEST WILL BE IN AUGUST

WHEN SEA ICE BEGINS TO THIN OUT AROUND THE BEARING SEA.AT THIS TIME LAST YEAR THERE WERE SOME WATER HOLES AROUND THE WEB CAMS. THIS YEAR THERE ARE NONE TO BE FOUND BUT THE ICE IS THINNING OUT FAST AROUND ( Tuktoyaktuk ) AND ALONG THE COAST COMPARED TO LAST YEAR.

WASHINGTON HAS OTHER IDEAS OF THE NORTH POLE MELTDOWN !!!

 

f the North Pole becomes ice-free this summer - the odds for that are 50-50, one scientist says - that doesn't mean that the whole Arctic region will become an open ocean.

 

Mark Serreze of the U.S. National Snow and Ice Data Center in Colorado told The Independent, a London-based newspaper, "I'd say it's even-odds whether the North Pole melts out."

 

The article, posted on the newspaper's Web site Friday, generated some confusion as to what would actually happen at the North Pole, and in the Arctic Ocean as a whole, as the summer melt season gears up in the next few weeks.

 

In a telephone interview with LiveScience, Serreze explained that a melt-out at the North Pole wouldn't mean that all Arctic ice would melt. Rather, the thin, newly-formed ice around 90 degrees latitude could melt away for a few days. Such an event would be significant, he said, because any holes that have appeared in the ice at the North Pole up until now have been a result of winds pushing the sea ice around and creating cracks, not the melt-related processes that have taken hold in the Arctic in recent years.

 

Usually, the North Pole is covered with thick, perennial ice that forms over several years. But during last summer's record melt, which opened up the fabled Northwest Passage, a substantial amount of older ice melted. (Typically only the thinner, first-year ice melts in the summer, while the thick, perennial ice survives.) Average sea ice extent at the end of the summer was 1.65 million square miles (4.28 million square kilometers), almost 30 percent lower than the previous record low.

 

As winter cooled the Arctic waters, ice re-formed over the ocean, as it usually does. But this newly formed ice is thinner, first-year ice, more susceptible to melting once summer comes around again.

 

As it happened, wind patterns and ocean currents over the last few months moved that newly formed ice smack over the North Pole, setting up the situation where at least a temporarily ice-free North Pole could form.

 

"It's this symbolic thing, I think," Serreze told LiveScience. "This is where Santa Claus lives ... it kind of hits you in the stomach."

 

The North Pole isn't the only part of the Arctic Ocean covered with this newly-formed ice - a substantial part of the region is capped by this thin frozen veneer. That "we're going to lose a bunch of ice," is more or less certain, Serraze said, but just where that melt will occur is "a roll of the dice."

 

One factor affecting where and how much ice will melt this summer is the somewhat higher ice extent that re-froze this winter. (While the winter extent was higher this year than last year, it was still about 390,000 square miles (1 million kilometers) smaller than average - that's equal to an area about the size of Texas and New Mexico combined.

 

Sea ice forms not by spreading out along the surface of the ocean, but rather as water just below the ice freezes onto the underside of the ice. This means that more ice probably also means slightly thicker ice, said Josefino Comiso of NASA's Goddard Space Flight Center, which helps monitor sea ice coverage. Thicker ice is more likely to survive the summer and become second-year ice, becoming thicker still in the winter.

 

The North Pole is also cooler than lower Arctic latitudes, meaning North Pole ice could better resist melting. Even if it does, there's still the possibility that winds could move the ice around so that a hole that formed at a lower latitude could be pushed over the North Pole, making it ice-free, Serreze said.

 

It's these weather patterns that scientists will be watching in the coming weeks to get a better sense of what will happen in the Arctic this summer. Serreze says that a warm spring season has put melting about on par with where it was at this point last year.

 

But other scientists say this summer's melt is unlikely to be as spectacular as last year's.

 

"We may not see a record minimum at all," said Tharston Markus, also of Goddard.

 

Scientists are monitoring the sea ice extent daily and say that after the main melt occurs over the next few weeks, they'll have a better idea of what the minimum extent, which typically occurs in mid-September, might be. For now though, all they can do is watch and wait.
