The forepaws are round and partially webbed. INSULATION -Whales, seals, and penguins are all fat; their fat (or blubber) adapts them to their life in the cold Antarctic. -The penguin has fatty tissue under its skin and feathers, that are short and close fitting and also provide insulation against the cold. -The feathers are arranged in such a way that they trap air to provide insulation and resist wind movement. -Plumage insulation provides about 80% of the total insulation of penguins and the feathers give out an oily substance which repels water and also helps to keep body heat in. -Plumage insulation is reinforced by subdermal fat which is found in all healthy penguins but reaches its greatest thickness in Emperor penguins (2-3 cm) and Adelies (1-2 cm). -When plumage and subdermal fat are exerting their greatest insulation efficiency, outward flow of heat is very slight. -Snow settling against the plumage of resting birds usually remains unmelted, forming an outer crust which further protects the birds from cold and wind. -The seal also has fatty tissue under its skin which retains heat; it has hair (a characteristic mammalian feature) -- out of the water, hair forms an effective insulation by trapping a stationary layer of air which is soon warmed by the body temperature. -In the water the air is driven out but the hair still retains a stable water layer which reduces heat loss. -The hair secretes an oily substance which adds to the insulative properties of the hair. -Another important function of fat is to act as a food reserve; because of their extensive blubber layer -- developed primarily as a means of heat conservation -- seals are able to undergo prolonged periods of fasting.

Such surfaces also accommodate aircraft landings. During the summer months, available insolation is fairly high because of long days and a relatively transparent atmosphere. Helicopters, used sometimes for recreational purposes, are noisy and produce a variety of sounds that are disturbing to seabirds.

Antarctica literally holds light within it. The point at which the wonder of natural phenomena begins to awaken the mind and imagination is the point at which art, science and humanity meet, and The Polar Project’s vision is to harmonize these perspectives. They are large bears, with many body characteristics adapted to cold temperatures, for moving across snow, ice and open water, And for hunting seals, which makes up most of their diet. Areas of significant winter cyclonic activity (storm tracks) are found in the North Pacific and Arctic, and significantly influences upon the high latitude climate. region, bringing in pulses of warm air, causing rapid warming and snow melt even in the middle of winter.
