Vastitas Borealis (Latin, 'northern waste' ) is the largest lowland region of Mars.
 It is in the northerly latitudes of the planet and encircles the northern polar region.
 Vastitas Borealis is often simply referred to as the northern plains , northern lowlands or the North polar erg of Mars.
 The plains lie 4–5 km below the mean radius of the planet, and is centered at .
 To the north lies Planum Boreum.
 A small part of Vastitas Borealis lies in the Ismenius Lacus quadrangle.
The Antarctic (US English , UK English or and or ) is a polar region, specifically the region around the Earth's South Pole, opposite the Arctic region around the North Pole.
 The Antarctic comprises in the strict sense the continent of Antarctica and the island territories located on the Antarctic Plate.
 In a broader sense the Antarctic region include the ice shelves, waters, and island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately 32 to wide varying in latitude seasonally.
 The region covers some 20% of the Southern Hemisphere, of which 5.5% (14 million km) is the surface area of the Antarctic continent itself.
 All of the land and ice shelves south of 60°S latitude are administrated under the Antarctic Treaty System.
 In a biogeographic sense, the Antarctic ecozone is one of eight ecozones of the Earth's land surface.
Half Moon Bay is an Arctic waterway in Qikiqtaaluk Region, Nunavut, Canada.
 Located off northwestern Bathurst Island, the bay is on the east side of May Inlet.
 Other bays in the area include Purcell Bay, Dampier Bay, and Stuart Bay.
The Dorsa Argentea Formation (DAF) is thought to be a large system of eskers that were under an ancient ice cap in the south polar region of Mars.
 The ancient ice cap was at least twice the size of the present ice cap and may have been 1500-2000 meters thick.
 This group of ridges extends from 270–100 E and 70–90 S, around the south pole of Mars.
 It sits under the Late Amazonian South Polar Layered Deposits (SPLD), in the Mare Australe quadrangle.
 The amount of these ridges is huge, one study studied seven different ridge systems which contained almost 4,000 ridges that had a total length 51,000 km.
Sally Poncet (born 1954) is an Australian-born scientist and adventurer who has explored and studied the Antarctic region since 1977.
 Her specialty is birds and she made extensive studies of albatross and their habitats for the British Antarctic Survey.
 She has written guidebooks on preservation of the flora and fauna of South Georgia and received numerous awards and honors, including the Blue Water Medal, the Fuchs Medal and the Polar Medal for her contributions to understanding the southern polar region.
The Centre for Polar Observation & Modelling (CPOM) is a centre for research into polar region processes which may affect: polar atmosphere and ocean circulation; the Earth's albedo; and global sea levels.
 It is funded by the Natural Environment Research Council, a UK Research Council.
Shamrock Bay is an Arctic waterway in Qikiqtaaluk Region, Nunavut, Canada.
 Located off northwestern Bathurst Island, the bay is on the south side of Sir William Parker Strait.
 Other bays in the area include Purcell Bay and Dampier Bay.
The Arctic ( or ) is a polar region located at the northernmost part of Earth.
 The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Northern Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia and Sweden.
 Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost-containing tundra.
 Arctic seas contain seasonal sea ice in many places.
Purcell Bay is an Arctic waterway in Qikiqtaaluk Region, Nunavut, Canada.
 Located off northwestern Bathurst Island, the bay is an arm of May Inlet.
Quark Expeditions is the leader in Arctic and Antarctic expedition travel.
 The adventure travel company offers Polar Region expeditions aboard purpose-built small expedition ships and icebreakers carrying fewer than 200 passengers, and on unique land-based adventures.
 Each polar expedition ship features ice-strengthened hulls for superior navigation in ice-packed polar waters, and Zodiacs (inflatable landing craft) for safe, comfortable transfers ship to shore, allowing passengers to reach some of the world’s most remote places.
 Expedition team members are experts in various disciplines including polar history, biology, geology, photography, ornithology, glaciology and more.
 Additionally, many expeditions feature renowned special guests and speakers.
 Adventure activities are offered on each expedition.
