Antarctica is protected by a treaty established in 1959 to be a continent used for peace and
science
Several thousand scientists inhabit Antarctic to study
Antarctic is also known as The South Pole
The only plants that grow in Antarctica are specialized forms of cold-loving algae that grow on
surface of snow
Animals in Antarctica don’t rely on plants for food, instead live on a very carnivorous diet
It is the driest, coldest, windiest place on Earth
During the summer, a day receives 24 hours of sun, but in the winter, you can hardly see any
sun at all
Animals that live in Antarctica have adapted to the cold and usually have thick layer of fat or
blubber to keep themselves warm
Antarctica is rocky continent covered in ice
Antarctica completely isolated and not connected to other countries
Numerous species of fish, crustacean and mollusk live beneath ice giving plenty of food for
carnivorous birds and mammals
Penguins are the most common animal found in Antarctica
Large predators like leopard seals and killer whales live in frozen islands and huge whales go
to Antarctic to eat food in nutrient-rich waters
It was first discovered by Roald Amundsen, a Norwegian explorer in 1911
Antarctica is the fifth largest continent
Antarctica covers nearly 8.9% of the world’s surface with and area of 13,000,000 sq km
Antarctica has no permanent population
It has a minimum temperature of -85to-90 degrees Celsius in the winter, and about 30 degrees
higher in the summer months
THE ARCTIC

The Arctic is also known as The North Pole

The Core of the Arctic lies in The Arctic Ocean

Some Inuit tribes live in The Arctic


The Arctic is divided into separate categories: The Geographic North Pole, located at the north
of The Arctic, The Magnetic North Pole that continues to shift, but approximately at 82°N and
114° South.
The first people to venture into The Arctic on April 6, 1909, were African American Matthew
Henson, Anglo-American Navy engineer, Robert Edwin Peary, and four Inuit guides

The Arctic Circle and Arctic Tundra are found at The North Pole

The Arctic covers up almost 500 million square miles of the northern hemisphere

The North Pole is made up of floating ice on the Arctic Ocean

The Arctic is connected to Canada and Europe giving The Arctic more plants and animals
than Antarctica
Foxes, large arctic owls, wolves, and Lemming and Arctic hares can be found during
springtime near the tundra feeding on plants and animals
Wolves and Polar bears dominate the frozen waters
Seals, killer whales, whales, sea lions, lions, walruses and narwhals can be spotted feeding on
fish in the Arctic Circle
Mines for oils and minerals, fishing and hunting bring pollution to The Arctic
Summer temperatures are about -10 to 10°C, but some areas can pass 30°, while winter
temperatures can drop to -50°C
LET ME IN!
WHAT MAKES THIS ENVIRONMENT HARD TO EXPLORE AND SURVIVE

Polar regions are almost always freezing, windy, dark and often very dry with no humidity

They have many dangerous wild animals that are almost impossible to tame

It’s very easy to get frostbite, scurvy ( lack of vitamin C), and hypothermia

Explorers have to prepare for mental preparation to face mental hardships

Explorers must undergo medical and dental exams to make sure they won’t collapse in field

Blood tests also need to take a series of blood tests to make sure your blood can be donated
in extreme cases

It is extremely expensive to send people down to the Arctic and Antarctic

Antarctica has an active volcano, Mount Erebus


Antarctic explorers face freezing temperatures and thin air at altitudes that often climb up
to 10000 feet above sea level
Antarctic explorers also face frigid blasts of wind call the katabatic winds that sweep from
the interior highlands to the sea

There is barely any resources to use to survive\

Polar regions are almost always isolated

Getting to polar regions takes at least a month of traveling through the icy landscape
BRRRR, IT’S COLD!

Polar regions are freezing, with the coldest temperature on Earth of -89°C recorded in
Antarctica
An average winter temperature in the Arctic is about -30°C
Arctic summers are relatively warm, especially on the coastal ends of the Arctic Ocean and
warm enough for people to live in and to grow vegetables
Antarctica is the coldest place on Earth because of its dryness, surrounding sea waters, and
higher elevations.
Polar regions also have plants that absorb sunlight like Lichen
The average temperature is always cold and averages -12°C to 6°C
Snow makes up most of the precipitation, but poles do not receive as much snow
Antarctica receives little less than 10 inches of snow, and 20 in the Arctic region
The snowfall is heavier in coastal areas where oceans create slightly warmer temperatures
Poles experience heavy winds however, the effects are different in each area
Antarctic receives fast winds and numerous blizzards that create a phenomenon, also
known a white where the sky and snow visually blend in
Two main types of polar climate, The “ice-cap”, or perpetual frost” climate which has subfreezing temperature all year
The tundra has minimum of one month’s average temperature is above freezing and comes
in three flavours: Arctic, Antarctic, and Alpine tundra, which is found in mountainous
terrains where cold temperatures are cold because of high altitude, regardless of latitude
Antarctica is the only continent where polar climate rules whereas the Arctic is more
diverse
I’M IMPORTANT TOO!

The Arctic and Antarctic are the places that scientists first go to, to conduct biological,
glaciological and climate research into the effects of “global change”
The poles are also used to research rises in temperature, greenhouse effect, UV radiation
and other industrial consequences
Quoting from Dr. Claude De Broyer, “The polar regions are much more liable to global
warming than other areas”

The hole in the ozone layer results in an increase of UV-B radiation

Polar regions are important regulators and drivers of the world’s climate

A lot of the weather that affects people in Europe comes from the Arctic




Our models show that in the future, polar regions will warm up more faster than the rest of
the world
Polar regions are like the “hot spots” of future climate evolution
If the Arctic and Antarctic continue to melt, and the Greenland ice sheet continues to melt,
the impact on the sea level would be global
The glaciers in polar regions are a huge supply of freshwater for us, and if we’re not
careful, that supply could get dumped into the ocean
BEEN THERE DONE

The first person to reach Antarctic was the Norwegian explorer Roald Amundsen
Amundsen was a veteran polar traveler and led a team of 18 men across Antarctica finally
reaching the pole on December 14, 1912
Amundsen’s rival was British Robert Falcon Scott who was the second person to reach
Antarctica
Tragically, Mr. Scott died on the way back because his team wore wool instead of heavy
down parkas
For many years, people believed that US Navy engineer Robert Peary was the first person
to reach the North Pole on April 6, 1909 accompanied by African American Matthew
Henson and four Inuit men named: Ootah, Seeglo, Egingwah, and Ooqueah
Matthew Henson was the only man that accompanied the seven arduous Arctic trips
between 1886 and1909 but was no given any credit until many years later
Douglas Mawson, an Australian explorer whom began to map the coasts of Antarctica and
collected geographical samples
Pyotr Anjou, a Russian admiral and explorer discovered the New Siberian Islands which
can be considered has a polar region
I BROUGHT A…

Sledges and dogs, snowmobiles, snowshoes are usually used to travel across the icy earth

Heavy fleece parkas need to be worn to avoid frostbite

Sunglasses are needed to block out the harsh sun




One of the ships to travel to Antarctica is an icebreaker, to cut through thick paths of ice in
the ocean
Synthetic Vitamin is used to avoid scurvy
Rovers can also be used to explore polar regions, because it’s very expensive to send people
there
Nuclear-powered submarines can reach polar regions from underwater
You would need a lot of things like: boots, two warm pairs of socks, gloves or mittens,
thermal/wool/synthetic blend of underwear, a hat, a first aid kit, sunscreen, lip balm with
SPF, food, a GPS and compass

You would need a snow house for shelter

Oil lamps are used for light and heat
AHHH! IT’S THE YETI!

The Yeti is an unique autonomous four-wheeled vehicle that will soon be driving around in
polar regions in the wastelands of Greenland bringing back climate, ice and atmospheric
data

The Yeti has a unique composite skin, electric motor and standard ATV tires

The Yeti will be sampling the air to figure out the chemical footprint of the base

The Yeti is autonomous and will be following a grid programmed to its GPS unit




The Yeti is a forerunner for a solar-powered rover called “Cool Robot” which will be going
through trials next year
The goal is to engineer a sturdy rover that can spend a long time on ice and still be able to
create power through solar cells to power its motor, communication n devices and onboard
instruments
James Lever, a mechanical engineer at the Army lab in Hanover, N.H. foresees a time
when an army of wheeled robots drive across the polar regions, picking up dat in
inhospitable places where human scientists don’t dare walk upon
It’s very expensive to put people in Greenland or Antarctica, robots are way easier
O CANADA!


The polar regions in Canada are located in the northern regions, (Northwest
territories, Nunavut, and the Yukon)
Canada has created many icebreaker ships, but has no use for them, so most of them
are sold to Russia, one to China

Many icebreakers were also decommissioned and sent to be scrapped

Canada has claimed parts of The Arctic (Nunavut)
STOP IT! YOU’RE HURTING
ME!

Tour groups are one of the biggest problems for polar regions

In some tour groups, it will be soon possible to start adopting polar bears for the rich



Mining for oil and minerals has become very popular
I suggest that miners don’t mine here, because of the population,, the Arctic glaciers
could start melting even more
Fishing companies catch a lot of fish, leaving animals like penguins with no food to
eat
Due to the many tour groups and explorers that come to the polar regions, even more
greenhouse gases are being let out into the air causing even more global warming
that will cause the glaciers to melt
