The Palmer Peninsula Ice Sheet (sometimes written as APIS) is widely considered sensitive to temperature changes as a result of its little size and northern location, and since this region is one amongst the foremost apace warming places within the world[2-5]. This sensitivity has been manifest through the collapse of diverse ice shelves, inflated ice velocities, and also the retreat and cutting of glaciers and ice caps.
The Palmer Peninsula may be a comparatively long, skinny spine Alpine-style mountain chain. These mountains extend north towards the Drake Passage, reaching 63°S. The Palmer Peninsula is seventy kick wide, with a median height of ~1500 m. It is 522,000 km2 in space and eightieth ice-covered.
You can explore the Palmer Peninsula Ice Sheet through the Google Map below. Note the flat ice shelves, the islands on the western and Japanese ground, and also the flow line structures of the glaciers as they flow into the ocean. You’ll be able to conjointly see the rifts within the Larsen ice and also the few mountain summits that poke through the ice.
Oceanography and climate
These mountains are like a big barrier to the persistent westerly, moisture-laden winds. The environmental condition regime either facet of the Palmer Peninsula is thus quite completely different. Within the Bellingshausen ocean, there’s a polar maritime climate, and within the Weddell Sea, a cold, dry, polar continental climate. The Weddell Sea is cooled by the Weddell Sea whorl that circulates ocean ice, icebergs and cold water dextral towards the northern Antarctic Peninsula. Ocean ice conjointly modulates ocean surface temperatures within the Weddell Sea.
