Transcript of Polar Regions

Polar Regions
The Polar Regions are a rough unforgiving environment. Mostly made up of ice, water and snow, it doesn't have very many inhabitants. There are two different Polar Regions: the Arctic, and Antarctica.
How do Scientists Currently Explore this Region?
What Are the Survival Difficulties When Exploring this Region?
What Technologies Would
You Use to Explore the
Polar Region?
The Arctic:

The Arctic, also know as the "North Pole" is the icy, snowy region that includes Canada, Russia, Alaska, Denmark, Norway, Finland, Sweden, and Iceland.
Antarctica:
Antarctica is the southernmost continent in the world and some people call it the "South Pole." Antarctica doesn't include any countries, not even itself because it's a continent not a country.
The difficulties are as followed:
1. Being as cold or colder than -50c
2. Falling through ice and either drowning or freezing to death
3. Avalanches can and will kill you if you aren't careful.
4. There's not much in the terms of animals, so you could starve to death.
5. Both the Arctic and Antarctica are huge so
you could get lost, freeze, starve or get
attacked by a polar bear or really
mean penguin.
For scientists to explore the Polar Regions, they use ice breaker boats to split the ice apart, so they can get further into the environment. They would use snowshoes to get across the snow quicker. To protect against the Sun's glare off the snow, and the Sun itself, they wear special glasses that have little slits in them, to keep less light out. To get around the environment quicker, they use snowmobiles, or special trucks like vehicles called sno-cats that have tracks instead of tires or wheels. To get up icy ravines and cracks scientists use ice picks and boots that have spiky toes. So they don't fall and get hurt, they use harnesses and climbing ropes.
To explore the Polar Regions we would use sno-cats, that would make it much easier to get across the snow, it would also be able to carry more people and equipment than a snowmobile. We would use a snowmobile too, to get to certain areas quicker than a sno-cat. We would use ice climbing gear to get up ice cliffs and if we do happen to fall into a ice ravine, we would be able to get out easily.
The reason the Polar Regions are so affected by climate change is because the snow and ice reflect most of solar energy from the Sun back into space. Since greenhouse gasses are warming our planet and causing the ice to melt, that means less solar radiation is reflected back into space, and is being absorbed be the Earth's surface and oceans. The extra energy warms the Earth even more thus causing more warming and more melting.
What is the Potential of Finding New Resources in this Extreme Environment?
The melting of the glaciers in the Polar Regions has opened up major transportation routes such as the Northwest, Northeast, and North passages. It has increased fishing, oil, and gas industries. The Polar Regions provide a broad selection of natural resources. A huge amount of country's get their resources from the Polar Regions
What Additional Information Can I Give My Team About the Polar Regions?
How is Communication Difficult in the Polar Regions?
In the Polar Regions they do not have telephones and the things that we have here. Instead they use dogsleds carry messages from one town to another and then the sled owners themselves go and tell people. Today they currently use geostationary (Geo) satellites to have communication in relatively unpopulated spots. There are also some spots in the Canadian Arctic that Geo satellites do not have communication in. The Geo satellites have limitation to what they can provide. They can't provide info or communication to mobile vehicles such as planes or boats. That leaves part of the Canadian Arctic territory without technology or communication.
