Being Arctic Tundra The Arctic Foxone of the world’s driest and coldest biomes, the Arctic tundra By Aanirudh Kheterpal is categorised as an extreme environment. The average temperature of this region, -12˚C to -6˚C, requires special adaptations in terms of thermal insulation. While the nonstop 50-60 days of summer sunlight is counterintuitive, this region also experiences 60-70 days of lightless winter, adding to the extremeness of this region. Low 15-25mm of annual rain is a concern, however, what’s more important is the year round permafrost, that is 25-100cm deep, and prevents plant growth. With prey hidden in tunnels under this permafrost, special adaptations are required in terms of hunting techniques.
The Arctic Tundra is located in only four places in the world, Canada, Alaska, Russia, and Greenland. The Arctic Tundra is known for its desert like conditions with much snow and cold weather. The word tundra comes from the from the Finnish word “Tunturia”, which means “treeless land.” This fits, as tundra’s usually have little to no trees/vegetation.The Arctic Tundra is generally a combination between a plant environment and a ice environment. However, whatever life lives in the Arctic Tundra, it is adapted to the climates and harsh conditions of the Arctic Tundra. Longitude - The longitude of the Arctic Tundra in Russia is 70° to 180° East Longitude.
Despite being one of the coldest, most inhospitable places on Earth, Antarctica hosts a wealth of biodiversity. A variety of species use the extreme climate and remoteness of the continent and its surrounding waters as a sanctuary and protection from predators. The Antarctic has not been immune to human influences and climate change, however, and its flora and fauna is suffering from a range of negative effects triggered by climate change. The polar regions are experiencing more dramatic changes than anywhere else on the planet in consequence of climate change and global warming. In Antarctica, climate change is having a range of impacts.
The names Antarctic Tundra, Arctic Tundra, and Alpine Tundra are the 3 main types of tundra. The Arctic Tundra is found north of the “snowforest” or taiga belt in the Northern Hemisphere and has only 2 seasons in the polar regions. A winter season and a summer season. Permafrost refers to the frozen soil of the tundra in the winter season. This permafrost (map of the arctic tundra) area reaches down to Canada and Russia (the taiga
There are a lot of amazing animals live in Arctic, like the Arctic wolf, orca, snowy owl, polar bear..etc. But, because of the global warming problem and climate change, Arctic got damaged. The location of Arctic makes the global warming impact super effective on
One situation that can be pointed out is the conservation of Orcas, which are also known as killer whales. As Animal Welfare Institute states, “ captivity decreases orcas lifespan” (AWI). AWI also discusses that orcas can swim up to 100 miles per day and routinely dive to 300 feet. In reality just imagine going on a boat ride way out in the ocean, and while gazing around an orca is spotted. Its huge body rises above the waters peeking out to seek whos around, but before any photos could be taken it is gone.
Ocean V. Space Exploration The ocean covers more than 70% of the Earth, yet we’ve explored only around 5% of it. This means there is so much more to explore in the ocean. The one reason we haven’t explored as much of the ocean is because of space. Space is wildly more popular, and has proven its worth with many advancements. The ocean, however, has major benefits: providing food, medicine, and the air we breathe.
This model has a surface grid whose spatial resolution is roughly 2.8 degrees lat/lon and 31 levels in the vertical. The ocean grid shares the same land mask as the atmosphere and there are 6 ocean grids underlying every atmospheric grid cell. The ocean resolution is therefore approximately 1.4 degrees in longitude and 0.94 degrees in latitude. This provides slightly better resolution of zonal currents in the Tropics, more nearly isotropic resolution at mid latitudes, and somewhat reduced problems with converging meridians in the Arctic. Data were downloaded in «NetCDF» format (Network Common Data Format) from the World Data Center for Climate (WDCC) (http://cera-www.dkrz.de/) and the «NetCDF4Excel» program (https://code.google.com/ p/netcdf4excel/source//NetCDF4 Excel_2007.xlsm) was used to convert the data files to the more conventional Excel format.
