On board the Healy, there is one helicopter that is being used by the folks from the National Marine Mammal Laboratory to do population studies. Today they went out for two runs. In the first run, the team saw a Polar Bear eating walrus. The photos for polar bear will be added as soon as they become available. If you’d like to learn more about them, read on.
Polar Bear Scientific name: Ursus maritimus
Polar Bear
Polar Bear Kill
Polar bears live year round near arctic waters hunting seal and other animals, rarely coming on land except on islands and rocky points. In winter they hunt along the Arctic shelves looking for tasty seals, fish, and even humans! Their white coats provide camouflage in the ice and snow which make them almost invisible as they stalk their prey.
In winter, when they are far from land they search for breathing holes made by seals. When the seal comes up for air, the polar bear will kill it and flip it out of the water with a single blow of its great clawed paw! Polar bears are very dangerous, and grow to a huge size and weigh as much as small automobile (1000 pounds). They have longer legs than other bears and large furry feet. These big feet help to distribute their weight as they walk on thin ice in the arctic waters. Polar bears are strong swimmers and can stay submerged for two minutes at a time. Their fur is made of hollow hairs which trap air and help to insulate them in the frigid waters.
In November polar bears retire to dens dug out of the snow or permafrost. The females remain until the spring when they emerge with one or two cubs who stay with them for the next year and a half. The males spend a shorter time in the dens and may be seen out and about at any time of the year.
19th Century Naturalist Edward Nelson Recounts:
"The Eskimo of Saint Lawrence Island and the American coast are well supplied with firearms which they use when bear-hunting. In winter, north of the straits, the bears often become thin and very savage from lack of food.
A number of Eskimo on the Alaskan coast show frightful scars obtained in contests with them in winter. One man, who came on board the Corwin, had the entire skin and flesh torn from one side of his head and face including the eye and ear, yet had escaped and recovered. One incident was related to me which occurred near Point Hope during the winter of 1880-'81. Men went out from Point Hope during one of the long winter nights to attend to their seal nets, which were set through holes in the ice. While at work near each other, one of the men heard a bear approaching over the frosty snow, and having no weapon but a small knife, and the bear being between him and the shore, he threw himself upon his back on the ice and waited. The bear came up and for a few moments smelled about the man from head to foot, and finally pressed his cold nose against the man's lips and nose and sniffed several times; each time the terrified Eskimo held his breath until, as he afterwards said, his lungs nearly burst. The bear suddenly heard the other man at work, and listening for a moment he started towards him at a gallop, while the man he left sprang to his feet and ran for his life for the village and reached it safely. At midday, when the sun had risen a little above the horizon, a large party went out to the spot and found the bear finishing his feast upon the other hunter and soon dispatched him. Cases similar to this occur occasionally al1 along the coast where the bear is found in winter."
