Thwaites Glacier ice shelf extends about 15 kilometers beyond the grounding line. Plus récemment, il a été observé que certaines parties du glacier s’amincissaient jusqu’à 4 m / an [17]. “It’s just an enormous amount of ice in this one glacier,” he said. Alley, S.

This value takes into account the volume above and below sea level (which already displaces water), and tells us how much global sea levels would rise if Thwaites Glacier were to melt completely. Nat. Experts believe that at their fullest extent, during the Ice Age, glaciers covered 30% of the Earth’s surface. En 2003, B-22 s'est brisé en cinq morceaux, avec B-22A resté dans les environs de la langue, alors que les autres morceaux plus petits dérivaient vers l'ouest. Along the 150-kilometer ice front, the satellite images show two different types of ice shelves. From 1992 to 2011, the centre of the Thwaites grounding line retreated by nearly 14 kilometres (nine miles). The Thwaites glacier has experienced significant flow acceleration since the 1970s. At about 5 a.m. last Tuesday morning, at latitude 74 degrees 57.4 S and longitude 106 12.8 W on the remote coast of West Antarctica, Thwaites glacier … Or la fonte de cette zone contribuerait (et contribue déjà) à une accélération significative de la montée de la mer[5],[6],[7]. A. Thwaites is close to one-and-a-half to two miles thick in places. Already, the glacier is responsible for about 4 percent of the world’s rising sea levels, according to a NASA news release. Teetering Balancing unsteadily. (A) Map of Antarctica with Thwaites Glacier (red box). Son écoulement le plus rapide est centré entre 50 et 100 km à l'est du mont Murphy.
