Arctic Research Papers

Arctic tundra can be found circling the North Pole and reaching far enough south to reach the coniferous forests of the taiga. The arctic tundra is most known for its cold, dessert-like conditions. It experiences

The tundra, which comes from the Finnish word, tunturi, which means treeless, is the coldest terrestrial biome known to biologists (University of California Museum of Paleontology). Located in the northern hemisphere, between 55° and 70° North, the Tundra covers about 20% of Earth’s surface (S). Although tundras can be found in many of the continents, most notably, the Northern Alaska, Canada and Greenland Tundra and the Scandinavian Montane Birch forest and grasslands stand out the most (Gardella). They are all large tourists attractions disply nature’s ability to thrive in the harshest environments. Winters in the tundra have an average temperature of -30° F, due to its high altitude. However, the average temperatures in the tundra during

Named for the Roman goddess of dawn, the aurora is a mysterious and unpredictable display of light in the night sky. The aurora borealis and aurora australis – often called the northern lights and southern lights – are common occurrences at high northern and southern latitudes, less frequent at mid-latitudes, and seldom seen near the equator. While usually a milky greenish color, auroras can also show red, blue, violet, pink, and white. These colors appear in a variety of continuously changing shapes. Sometimes the aurora is so dim and scattered as to be mistaken for clouds or the Milky Way; sometimes it is bright enough to read by. What does an aurora look like? Auroras can appear as long, narrow arcs of light, often extending east to west

There are three main sections to this module: terrestrial coordinates, celestial equatorial coordinates, and understanding how the ecliptic is related to seasons on the Earth. Each of these sections has its own simulator(s). The background material necessary to utilize these tools is contained in each section.

The tundra is one of the cooldest land biomes on the planet. Due to the high winds and the permafrost there are no trees becuase it dosent allow the growth of deep roots. All the producers and othe need to get adapted to the cold temperatures, little sun and short growing season to stay alive. The tundra is considered a poor enviroment thats low in resources. The dead minerals get recycled by othe decomposers like the slime molds, fungi, and bacteria. Rain increases photosynthesis and decomposition. Air pollution kills lichen in the cold tundra. The warmer climates allow trees to invade the shade out the small tundra plants. And warmer temperatures can increase decompositon, while releasing more CO2 into the air causing mor global

The arctic Tundra is normally around 10 to 29 degrees fahrenheit. Rainfall may vary in different regions of the arctic. Yearly precipitation, including melting snow, is 6 to 10 inches. Soil is formed slowly. The biggest threat to the Tundra is global warming. Many scientists believe global warming caused by greenhouse gases may eliminate Arctic regions, including the tundras there, forever. Another concern is that about one third of the worlds soil-bound carbon is in the tundra permafrost. Cutting greenhouse gas emissions by switching to alternative energy uses is key to protecting Earth's tundra habitats. The Tundra is located at the top of the earth by the North Pole. Switch to alternative energy

North Sea. During these expeditions they endured cold, and famine, but though these conditions are tough Robert didn’t lose a single drop of curiosity of what the north pole looks and feels like. as they traveled through Russia Robert decides to stay in Russia until he can hire a ship which can be done by just paying the insurance for the owner, and then set sail by June.

In the Northeastern part of Russia, summers are cold and winters are colder. The Siberian Tundra is home to many abiotic factors such as strong winds, little precipitation, and short summers days. With poor soil and permafrost, the tundra could soon be gone, or at least cause dramatic changes to the earth. According to Evans (2002), the grounds of the Siberian Tundra are misty during the summer. The average temperature in the Tundra is 37 to 54 degrees yet, in these short months of summer, the Siberian tundra has a permafrost layer that is starts to disappear. This loss of permafrost is resulting in the rise of carbon emissions, which contributes to global climate change. Through research, we can better understand the disappearance of the permafrost layer in the Siberian tundra. How and why is it disappearing, and what impact this disappearance is having on the tundra, and on a much larger scale, the Earth?

During these solstices, the rays of the Sun shine directly on one of the two Tropics. During the June Solstice the rays of the Sun shine directly on the Tropic of Cancer and during the December solstice, the Sun’s rays shine on the Tropic of Capricorn.

On rare occasions, the Northern Lights have been spotted further South.The lights seen South of the equator are called the Aurora Australis.

Aurora- Light of Mystery Text Box: This shuttle image shows the characteristic oval shape of the aurora.i What is aurora? Auroras, or polar lights, are the luminous phenomenon of the upper atmosphere occurs in high latitudes of both hemispheres. Auroras in the northern hemisphere are called aurora borealis and those in the south hemisphere are called aurora australis. Aurora (Latin for 'dawn') is beautiful and amazing lights which are visible in the dark sky in the poles.
