The Barnes Ice Cap is an ice cap located in central Baffin Island, Nunavut, Canada.
It covers close to 6,000 km2 (2,300 sq mi) in the area of the Baffin Mountains. It has been thinning due to regional warming. [1] Between 2004 and 2006, the ice cap was thinning at a rate of 1 m (3 ft 3 in) per year.
The ice cap contains Canada's oldest ice, some of it being over 20,000 years old. [2] It is a remnant of the Laurentide Ice Sheet, which covered much of Canada during the last glacial period of the Earth's current ice age. Generator Lake is located at the southeastern end of the ice cap. [3]

The Canadian Shield, also called the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton, the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible. As a deep, common, joined bedrock region in eastern and central Canada, the Shield stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada and most of Greenland; it also extends south into the northern reaches of the United States.
Greenland is located between the Arctic Ocean and the North Atlantic Ocean, northeast of Canada and northwest of Iceland. The territory comprises the island of Greenland—the largest island in the world—and more than a hundred other smaller islands. Greenland has a 1.2 kilometre long border with Canada on Hans Island. A sparse population is confined to small settlements along certain sectors of the coast. Greenland possesses the world's second-largest ice sheet.
The cryosphere is an all-encompassing term for the portions of Earth's surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground. Thus, there is a wide overlap with the hydrosphere. The cryosphere is an integral part of the global climate system with important linkages and feedbacks generated through its influence on surface energy and moisture fluxes, clouds, precipitation, hydrology, atmospheric and oceanic circulation.
Ellesmere Island is Canada's northernmost and third largest island, and the tenth largest in the world. It comprises an area of 196,236 km2 (75,767 sq mi), slightly smaller than Great Britain, and the total length of the island is 830 km (520 mi).
Baffin Island, in the Canadian territory of Nunavut, is the largest island in Canada and the fifth-largest island in the world. Its area is 507,451 km2 (195,928 sq mi) with a population density of 0.03/km²; the population was 13,039 according to the 2021 Canadian census; and it is located at 68°N70°W. It also contains the city of Iqaluit, which is the capital of Nunavut.
Baffin Bay, located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. It is sometimes considered a sea of the North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador Sea. The narrower Nares Strait connects Baffin Bay with the Arctic Ocean. The bay is not navigable most of the year because of the ice cover and high density of floating ice and icebergs in the open areas. However, a polynya of about 80,000 km2 (31,000 sq mi), known as the North Water, opens in summer on the north near Smith Sound. Most of the aquatic life of the bay is concentrated near that region.
Devon Island is an island in Canada and the largest uninhabited island in the world. It is located in Baffin Bay, Qikiqtaaluk Region, Nunavut, Canada. It is one of the largest members of the Arctic Archipelago, the second-largest of the Queen Elizabeth Islands, Canada's sixth-largest island, and the 27th-largest island in the world. It has an area of 55,247 km2 (21,331 sq mi). The bedrock is Precambrian gneiss and Paleozoic siltstones and shales. The highest point is the Devon Ice Cap at 1,920 m (6,300 ft) which is part of the Arctic Cordillera. Devon Island contains several small mountain ranges, such as the Treuter Mountains, Haddington Range and the Cunningham Mountains. The notable similarity of its surface to that of Mars has attracted interest from scientists.
A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice.
The Laurentide Ice Sheet was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glacial epochs, from 2.58 million years ago to the present.
Auyuittuq National Park is a national park located on Baffin Island's Cumberland Peninsula, in the Qikiqtaaluk Region of Nunavut, the largest political subdivision of Canada. The park was initially known as Baffin Island National Park when it was established in 1972, but the name was changed in 1976 to its current name to better reflect the region and its history. It features many terrains of Arctic wilderness, such as fjords, glaciers, and ice fields. Although Auyuittuq was established in 1972 as a national park reserve, it was upgraded to a full national park in 2000.
Melt ponds are pools of open water that form on sea ice in the warmer months of spring and summer. The ponds are also found on glacial ice and ice shelves. Ponds of melted water can also develop under the ice, which may lead to the formation of thin underwater ice layers called false bottoms.

The retreat of glaciers since 1850 is well documented and is one of the effects of climate change. The retreat of mountain glaciers, notably in western North America, Asia, the Alps and tropical and subtropical regions of South America, Africa and Indonesia, provide evidence for the rise in global temperatures since the late 19th century. The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level, which would affect coastal regions. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26-year period from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per yr.
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories:
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.
SHARAD is a subsurface sounding radar embarked on the Mars Reconnaissance Orbiter (MRO) probe. It complements the MARSIS radar on Mars Express orbiter, providing lower penetration capabilities but much finer resolution.
The Baffin Mountains are a mountain range running along the northeastern coast of Baffin Island and Bylot Island, Nunavut, Canada. The ice-capped mountains are part of the Arctic Cordillera and have some of the highest peaks of eastern North America, reaching a height of 1,525–2,146 metres (5,003–7,041 ft) above sea level. While they are separated by bodies of water to make Baffin Island, they are closely related to the other mountain ranges that make the much larger Arctic Cordillera mountain range.
The Penny Ice Cap, formerly Penny Icecap, is a 6,000 km2 (2,300 sq mi) ice cap in Auyuittuq National Park of Baffin Island, Nunavut, Canada. It forms a 2,000 m (6,562 ft) high barrier on the Cumberland Peninsula, an area of deep fjords and glaciated valleys. It is a remnant of the last ice age. During the mid-1990s, Canadian researchers studied the glacier's patterns of freezing and thawing over centuries by drilling ice core samples.
The Devon Ice Cap is an ice cap on eastern Devon Island, Nunavut, Canada, covering an area of over 12,000 km2 (4,600 sq mi). The highest point on Devon Island is found at the summit of the ice cap, with an elevation of 1,921 m (6,302 ft). The ice cap has a maximum thickness of 880 m (2,887 ft), and has been steadily shrinking since 1985.
