The North Pole

  1. 1. The North Pole
  2. 2. The Arctic <ul><li>Survival IS possible </li></ul><ul><li>Nearly 4 million people (the population of Connecticut) and 8 different nations endure these extremes </li></ul>CROW-too-ah = I am Cold (Western Eskimo)
  3. 3. North Magnetic Pole VS. North Terrestrial Pole
  4. 4. <ul><li>North Magnetic Pole- </li></ul><ul><li>shifts 6-25 miles every year, 6.5-10 feet thick ice cap floating above the Atlantic Ocean, the magnetic field in which compasses point to </li></ul><ul><li>North Terrestrial Pole- </li></ul><ul><li>an axis on which the earth spins, point on the map, about 600 miles away from magnetic pole </li></ul>
  5. 5. What To Wear <ul><li>Clothing </li></ul><ul><li>-several layers of loose light porous windproof clothing </li></ul><ul><li>(Do NOT wear waterproof)* </li></ul><ul><li>-WEAR WOOL & FURS! </li></ul><ul><li>- 40-45% body heat can be lost through exposure of the head, hands, feet, neck, wrists, ankles.. </li></ul><ul><li>Keep covered at all times!! </li></ul><ul><li>*Clothes must prevent snow compacting, but be porous enough to allow water vapor to escape </li></ul>
  6. 6. <ul><li>Remember… </li></ul><ul><li>C - Keep clothing clean </li></ul><ul><li>O - Avoid overheating </li></ul><ul><li>L - Wear clothes loose and in layers </li></ul><ul><li>D - Keep clothing dry </li></ul>
  7. 7. Supplies <ul><li>-Snow Goggles-protect eyes from snow blindness </li></ul><ul><li>(can be made of scrap material such as wood) </li></ul><ul><li>-Dog Sleds & Snow Shoes= way of transportation </li></ul><ul><li>-Food Availability = LOW </li></ul>
  8. 8. Arctic Temperatures <ul><li>Winter temperatures in Feb </li></ul><ul><li>(-31 ◦ F) </li></ul><ul><li>Summer temperatures in July </li></ul><ul><li>(32 ◦ F) </li></ul><ul><li>Wind Chill* </li></ul>
  9. 9. * Sun is low and thin spread in high latitudes *Extreme arctic climates are due to spherical geometry
  10. 10. Human Adaptations <ul><li>Temperature regulation </li></ul><ul><li>Shivering- blood vessels dilate and contract </li></ul><ul><li>Hypo metabolism saves energy </li></ul><ul><li>-secretion of thermogenic hormones such as thyroid and adrenal hormones- increase body heat </li></ul><ul><li>High blood pressure </li></ul><ul><li>-cold-induced increase in the peripheral resistance </li></ul>
  11. 11. S.A.D. Seasonal Affective Disorder <ul><li>-Seasonal changes in levels of brain chemicals such as melatonin and serotonin in response to change of exposure to light and darkness </li></ul><ul><li>-Sad/ Depressed- Suicides increase </li></ul><ul><li>-Vitamin D </li></ul><ul><li>-* Can cause rickets, tetanus and osteomalacia </li></ul>
  12. 12. Hypothermia <ul><li>Total body cooling, a bodily response which occurs when the right conditions are present such as wind exposure, wet conditions, where the body becomes very cold, coupled with total exhaustion </li></ul><ul><li>94 ≥˚ F </li></ul>
  13. 13. Frost Bite <ul><li>Body’s inability to compensate for cold exposure that produces injury </li></ul><ul><li>-Time of exposure, humidity, clothing WIND CHILL </li></ul><ul><li>Temperature drops, blood flow to surface decreases, blood vessels dilate, fluid shifts and crystal formation occurs </li></ul>
