Glaciers des Pyrénées : une fonte à fond la caisse

Les Pyrénées françaises ont connu une dégradation record cet été. Mythique et massif, le glacier d’Ossoue a perdu 5 mètres d’épaisseur et bat en retraite.

#Photographers Jo Scott and Jake Scott-Gardner worked together to capture this #photograph. They achieved this 70 picture panorama using a Nikon D810 camera with a 35mm lens for 20 second exposures at an aperture of f/1.4 and ISO 8000. They focus stacked the foreground, since they used a wide aperture. Both the foreground and background were photographed at the same time because the camera settings and location provided enough light to do so. Their general post processing includes correcting lens distortion, focus stacking the foreground images, stitching all of the images together, masking any out of focus sections, and finally adding edits including contrast and saturation.

Record heat waves in Swiss Alps

The ski resort, Glacier 3000, in the Les Diablerets area of western Switzerland said this year's ice melt was around three times the 10-year average.

"Ten years ago I measured about 15 metres of ice. So more than 15 metres of ice and snow have melted," says Mauro Fischer, a glaciologist at the University of Bern's Institute of Geography.

Ancient hiking trail revealed as Swiss glacier retreats by 15 metres

An Alpine path between two glaciers in Switzerland is emerging for what a local ski resort says is the first time in at least 2,000 years after the hottest European summer on record.

The thick layer of ice that has covered a Swiss mountain pass for centuries will have melted away completely within a few weeks. This summer's heatwave hitting Europe has been catastrophic for the Alpine glaciers, which have been melting at an accelerated rate

Following a dry winter, the summer heatwaves hitting Europe have been catastrophic for the Alpine glaciers, which have been melting at an accelerated rate.

The pass between #Scex Rouge and #Tsanfleuron has been iced over since at least the Roman era.

But as both glaciers have retreated, the bare rock of the ridge between the two is beginning to emerge -- and will be completely ice-free before the summer is out.

"The pass will be entirely in the open air in a few weeks," the #Glacier 3000 ski resort said in a statement.

While the ice measured around 15 metres (49.5 feet) thick in 2012, the ground underneath "will have completely resurfaced by the end of September".

Swiss mountain pass set to lose all ice within weeks

The thick layer of ice that has covered a Swiss mountain pass for centuries will have melted away completely within a few weeks, a ski resort said Thursday.

Sea Level Rise From Melting Ice Sheets Could Soon Be Locked In

Quand des glaciers recouvraient la Namibie

une équipe de chercheurs menée par Pierre Dietrich de l'université de Rennes a découvert tout un réseau de paléo-fjords sur la côte nord-ouest de la Namibie. Ces fjords se sont formés durant l'avant-dernier épisode glaciaire datant de la fin du Paléozoïque. Cette période a duré de -360 à -260 millions d'années, ce qui en fait une glaciation particulièrement longue dans l'histoire de la Terre.
À cette époque, la Namibie faisait partie du supercontinent Gondwana. « Il s'agit du premier exemple de fjords fossiles intégralement préservés », explique Pierre Dietrich. « Le paysage désertique du nord de la Namibie est en réalité un paléo-paysage glaciaire ! »

Le réseau de paléo-fjords de Namibie se caractérise aujourd'hui par des vallées incisant une série de plateaux. Ces vallées, occupées désormais par des rivières, sont larges de 1 à 5 kilomètres et font 80 à 130 kilomètres de long. Leur passé glaciaire ne fait pas de doutes pour les géologues : leur fond ainsi que leurs flancs sont marqués par les traces du passage des anciens glaciers. Stries et rayures, ainsi que diverses marques de frottement et d'abrasion de la glace, marquent les roches du socle. Ces traces permettent d'ailleurs d'établir le sens d’écoulement de l’ancienne masse glaciaire.
Les chercheurs ont également trouvé des sédiments glaciogéniques datant d'environ 300 millions d'années, composés de nombreux débris rocheux. Grâce à ces témoins de la glaciation ainsi qu'aux sédiments post-glaciaires les surmontant, les géologues ont pu reconstruire la dynamique de la couverture glaciaire de l'époque.
