POLAR REGIONS EXPLORING THE EXTREME ENVIRONMENT BY FRASER HOPEWELL
* Because The North Pole is surrounded by water, it is warmer than the South Pole. This happens because the water holds onto heat and heats up the pole. Although The North Pole is warmer than the South Pole, it is still quite cold. The average temperature in Winter is -30 degrees Celsius (-30 Fahrenheit), while the average temperature in summer is 0 degrees Celsius (32 Fahrenheit). The ice at the north pole is somewhere around 3 meters thick, although, through global warming this number is dropping. WEATHER IN THE NORTH POLE (1/2)
The south pole has one of the coldest climates of earth, very similar to the desert because of the minimal amount of precipitation and humidity in the air. Another contributing factor to the south pole’s cold climate is the fact that during the winter, the sun never appears on the south pole horizon, it does however appear during the summer but always hugs the horizon. Average winter temperature in the south pole is -65 degrees Celsius (-85 Fahrenheit) while in summer, the average climbs to about - 25 degrees Celsius (-12 Fahrenheit), much colder than the North Pole. WEATHER IN THE SOUTH POLE (1/2)
Some of the Arctic is in Canada, in fact the farthest north city in the world is in Canada. It is called Resolute, it’s in Nunavut. Most of Canada’s 3 Territories are covered in snow for most, if not all of the year. This trend is a lot like the arctic. Temperatures are also very cold in the territories, but mostly in Nunavut. In fact the North pole was first discovered by Robert Peary, an explorer aided by two Canadians from nowadays’ Nunavut. THE NORTH POLE & CANADA
Probably the biggest obstacle that explorers face when exploring the poles is the temperature. Frostbite is very common at the poles, leaving many explorer’s with amputated fingers & toes, sometimes even limbs are amputated due to frostbite. Another obstacle that the explorers face is the declining thickness of ice, with many explorers falling through. A car somehow managed to drive from Resolute to the North Pole despite the ice or lack there of thickness. THE ROUGH CONDITIONS & OBSTACLES IN THE ARCTIC
English television show Top Gear recently drove the Toyota Hilux from Resolute, Canada to the North Pole. Two of the three host’s on the show drove the Hilux and set off on 1:00, April 27, 2005. They ran into many obstacles along the way including ice fields, and the thin ice. Once, one of the car’s tires broke through the ice, and had to be towed out by the other which the camera crew was travelling in. They reached the pole in one piece, which made them the first ever to reach the north pole in any automobile. DRIVING IN THE ARCTIC
The Toyota Hilux that the Top Gear crew and hosts used were heavily modified by an Icelandic vehicle modification company. A few added features on the modified Hilux’s were 38” Snow Tires and two winches in case any of the cars got stuck. This wasn’t the last time that Top Gear used the Hilux for its durability, James May later used it to get close enough to a still erupting volcano, in hopes of returning with a souvenir.

Mobility is the importance of this expedition. With the newfound knowledge that cars can drive at the north pole quicker than the preconceived way, explorers can be more mobile on their journeys and also carry more equipment with them. This expedition proved that heavily adapted cars can make the trip to Polar Regions and come back in one piece. With greatly improved cargo space an SUV offers, explorers could bring more equipment and make larger discoveries. WHAT IS THE IMPORTANCE?
The Toyota Hilux functions like any other car, with fuel powering the engines which powers the wheels, effectively making the car go. However the people at Top Gear made some modifications to the engine and battery to make them last longer. They added heaters to the engine to increase fuel and coolant temperatures so that they would not freeze. They also installed a large heavy duty battery. The air intake on the Hilux was also adapted. Lastly they fitted a 90 litre auxiliary fuel tank. An extra large sump guard was also added. HOW DOES THE TECHNOLOGY WORK?
Before people explore the Polar Regions they should first hire a guide. They are worth the expense. Another step that they can take to be responsible while exploring is to join an expedition with professionals who do this kind of stuff as a career. Try not to leave any bodily waste behind because it damages the eco system. Try not to come in contact with any wildlife because they can harm you. Lastly try not to use excessive amounts of heat because it could melt the ice. HOW CAN HUMANS EXPLORE POLAR REGIONS RESPONSIBILITY?
The Dogsled was invented by Canadian Inuit's. The dogsled is used to travel to these harsh environments. It is powered by 8-10 dogs that have different positions within the group. The sleigh on the back of the dogsled can hold up to 2 people and small bags. The dogs are kept in kennels and are well fed prompting good behaviour and obedience. Dogsleds have been used by many expeditions to the pole and raced against the car in the expedition I studied. Although the dogsled lost to the car, it still got the people who were commandeering it quite close to the pole. CANADIAN TECHNOLOGY FOR POLAR REGIONS?
