shelves remain in four basins along the coast: Dryglaski, Edgeworth, Pyke and Sjögren. All of them are losing mass except for the Pyke Glacier. The ice shelf collapse in 2002 triggered a perturbation of a massive accelerated flow. The instability of the ice shelves' mass can be traced back to changes in climate. The Larsen B ice shelf has contributed to 17% of the mass depletion rate of the Antarctic Peninsula. The decline in mass from the Larsen A and Larsen B ice shelves have contributed to sea ice, atmosphere and ocean changes. With temperatures changing, so do the ice shelves; accelerated melting occurs, subsequently changing ocean masses and temperatures.
169:. The Nordenskjöld formation between Cape Longing and Cape Sobral consists of Upper Jurassic-Lower Cretaceous anoxic mudstones and air-fall ashes. There is a possibility of a strike-slip formation based on evidence of deformation, dewatering and lithification. The deformation period was during Tithonian times, and provides further evidence of a plate boundary caused by the break-up of Gondwana along the eastern peninsula. The Nordenskjöld formation went through a significant burial period before the Miocene time which brought on uplifting and block faulting, exposing the area once again. 1277: 1509: 107:
location makes it prone to change due to global warming. The length and thickness of the ice sheet connected to the Nordenskjöld coast is monitored to track fluctuating climate patterns. Ice shelves, called the Larsen shelves, found on the eastern side of the peninsula, have decreased significantly in recent years. The Larsen A ice shelf that was extended from the Nordenskjöld Coast disintegrated in 1995. There are now only a few small ice caps remaining along the Nordenskjöld coast.

Weddell Sea pressure cell. The Weddell Sea is one of the coldest masses in the ocean. This tends to build up in this area due to the damming-up effect against the high slopes on the eastern side of the Antarctic Peninsula. The coast experiences a barrier effect of winds in response to the mountains blocking its path. This effect means wind speed can accelerate to gale force. During the 1902 expedition they recorded speeds of hurricane force.
258:(permanent frozen ground) and seasonal thaw-activity are the main indicators of climate change. There is a correlation between the mean annual temperatures of the arctic and the boundaries of permafrost on the Antarctic Peninsula, meaning that rising temperatures impact the mass of permafrost. Permafrost can survive if the mean annual temperature remains − 2.5 °C. Due to 146:
during the Cretaceous and Tertiary age. It found that the area was a cordilleran belt of folded strata, overlain by sedimentary rocks and volcanic beds from the Mesozoic time. This discovery, during the 1901 expedition, led scientists Dalziel and Elliot (1971,1973) to further amplify the theory of the Pacific crust subduction under the western continental margin.

surrounded by glaciers, which extends to Palmier Peninsula. Larsen Bay, which lies between Cape Sobral and Cape Longing, also has a fiord in the middle of its shoreline. Cape Ruth is an area of high peaks that leads to the eastern entrance of Drygalski Bay. The fiord behind Cape Ruth forms the head of Dryglaski Bay.  
225:, which means that all 12 months of the year average a temperature below 0 °C. Along the Antarctic Peninsula over the past 50 years the mean temperature has increased by 3.4 degrees Celsius and the mid winter temperature by 6 degrees. This makes the Antarctic region one of the global hotspots for climate change. 172:
Between Cape Longing and Cape Sobral, the Nordenskjöld formation is, at its thickest, around 450 cm. It is characterised by ash beds and radiolarian-rich mudstones, around 580m deep. Reports of new calcisphere species, microorganisms that allow scientists to determine time and place in relation

Due to the steep mountains that line the Antarctic Peninsula, the south-west winds are cold and strong. First noted in the Swedish Expedition in 1902, Otto Nordenskjöld found that these winds are present along the entire coast of the Peninsula. These strong, cold winds are due to the semi-permanent

Scientists can enhance the processes that control the way atmospheric changes affect the ice shelves. With satellite altimeter studies, which records the density and surface lowering of ice shelves, they can better understand the loss of mass on the shelves. This allows ocean divers and other

The region of the Nordenskjöld Coast has particularly steep slopes on the coast, with high covered ice plateaus. Cape Sobral lies 12 miles from Cape longing. It is a high plank of rock that is projected above the water below, and is partly snow free. Behind Cape Sobral is a deep fiord that is

The Larsen A ice shelf is an extension of the Nordenskjold Coast; Larsen B is located to the south. The Larsen A ice shelf experienced a major disintegration in 1995, which triggered the collapse of the Larsen B ice shelf in 2002. This then triggered an acceleration of the flow from outlet

Due to the harsh weather conditions and the loss of necessary transport, when their boat sunk, the expedition could not explore the coast of the Antarctic Peninsula until springtime in the following September. 88:(64° 30' S 60° 30' W) is located on the Antarctic Peninsula, more specifically Graham Land, which is the top region of the Peninsula.
