The monumentous Mackenzie River flows approximately 3oo cubic kilometer of freshwater from Canada’s Northwest Territories and to the Arctic Ocean annually. This river is a part of a basin with tributaries, other rivers, and forests; it is considered to be a climate stabilizer. It is only a significant, intricate member of a network made entirely of other small rivers that run across the Canadian Arctic Archipelago. Freshwater cycles through the Canadian Arctic Archipelago (aka the CAA) and ends up being distributed into the North Atlantic. Essentially, the Mackenzie River is a basin full of permafrost; it is very centered on the cold temperatures. This is a very risky business. As temperatures continue to rise, the permafrost and glaciers around …show more content…
The fluctuating tides based on density levels, salinity, surface heat and freshwater amounts available is defined as thermohaline circulation, also known as the great ocean conveyor belt. In colder areas, and Polar Regions, the warmer surface water becomes cool enough and dense enough in salinity to sink the bottom of the ocean and pushes the deep water into shifting and rising. It is postulated that an outpouring of fresh meltwater upset the salinity balance of the surface water, preventing it from becoming dense enough to sink and stopping the thermohaline circulation, caused the world to be catapulted another Ice Age. A research team of University of Sussex, commanded an expedition to study the gravel and boulder deposits from the Mackenzie River basin as well as the Athabasca Valley for clues or indications of meltwater travel. These physical structures do indeed suggest that there were two floods, one of which is estimated to coincide with the approximated timing of the flood that slingshot the northern hemisphere into glacier …show more content…
On average, CAA contributors have higher alkalinity capacities, and lower concentrations in barium. Coppermine, Thornsen, Kujjuua, and Cunningham CAA rivers actually match Mackenzie River in retrospect. These differences could be due to differences in sedimentology, geology, vegetative growth, surrounding wildlife and plant growth, as well as the flowing water sources. Most CAA contributors actually originate or are confined inside the Arctic Circle; this means most recurrent accretion is from snowfall or glacier release. Logically, during seasonal cycles, water movement crests during the summer and strains in the winter. Of course, once all these tributaries, streams, and rivers (the CAA plus the Mackenzie), are finally added together their geochemical make-up has been altered via mixing. The study is on-going, and researchers continue to accumulate data from river
The Northeast region is the best region because it has a lot of very important, historical landmarks. Also it has amazing products & natural resources that you might love. Best of all we got the most beautiful climates that I personally love and I think you should too.
Have you ever thought about driving over a suspension bridge held up by cables? That’s what the Mackinac Bridge is. With the building of the Mackinac Bridge there has been many positive effects that have come out of it.

The Mohegan Indians are located in the southeastern part of Connecticut near the Thames River Valley in Uncasville, with a current population of approximately 1,000 members. All of the members are of Native American decent and were once associated with the Pequot tribe. "Scientific evidence shows the Native American presence in the area for 10,000 years, but the oral history begins with the beginning, when the Great Spirit created the earth" (http://moheganindians.weebly.com/). The first group of Mohegan’s was part of the Delaware tribe which was called the Wolf Clan, that settled in upstate New York. The Native languages of the Mohegan Indians are English and they also have their own Mohegan dialect, which is called "Algonquin dialect". In this Native language the name Mohegan means "People of the wolf", which fits the tribe perfectly as they were once a heterogeneous group in which the men went to war to protect their tribes and would also go hunting to put food on their families tables while the women stayed home to take care of the children and were horticulturist as they worked in the fields farming each day. Each individual played a major part in keeping the tribe together as a one functional unit.
Currently, over half of the world’s population lives in urban based areas (Owrangi et al, 2014), and this increase in population is expected to contribute to further increases in flood risks (ibid). Vancouver has achieved rapid socioeconomic development due to the increased employment opportunities and growth rates, directly stressing local natural resources by increasing population and urbanization (Owrangi et al, 2014).
The Arctic has a key role in Canada’s history and future, as 40% of Canada’s landmass composes of its three northern territories. Arctic Sovereignty has become a national priority for Canada in the 21st Century due to international interests, such as rapid industrialization, climate change and transportation. Therefore, the geopolitical importance of the Arctic has never been any greater than it is now.
...tario. The great lakes Water Quality Agreement is an international agreement between Canada and the United States their collective goals are to restore and maintain the Great Lakes. The agreement outlines the commitments of both countries to restore and maintain water quality and aquatic ecosystem health in the Great Lakes. Since 1989 Canada has spent 355 million dollars to help restore the ecosystems. Canada currently invests 48 million a year on the restoration projects. President Barack Obama's administration developed the Great Lakes Restoration Initiative in 2009, that provided $475 million dollars the first year and $300 million annually since. Last year a house subcommittee proposed slashing the allocation to 60 million starting in 2014. It is feared that this 80% cut would gut the programs and this would have a major impact on Canada and the U.S. Sources

The thoroughly knowledgeable staff of Captain Mark Yuknat along with wife Mindy, crew Scott and Cathy provide a wealth of information related to the various species of bird, habitat and environment.
California’s Mono Lake is three times more saltier than the Pacific ocean. When measuring the chemicals, that is. It's on the opposite end of the pH scale from acids. The lake is full of alkaline bases that make the water have a slimy and soapy feel.
That complexity makes it difficult to measure. Nearly all of these channels funnel into Baffin Bay. The Davis Strait bounds the southern end of Baffin Bay, and thus provides a convenient “choke point.” By measuring at this one location (rather than in the many channels to the north), it captures all of the water going in and out of the Canadian Arctic Archipelago. As a connector between the Arctic Ocean and the Atlantic Ocean, the Davis Strait is a unique environment to study water
For thousands of years dreams of permanently diverting stream water from the Salt and Verde rivers to the arid desert lands of Arizona, through a myriad of canals, would finally come to fruition in the early twentieth century. Flooding and or droughts would always seem to destroy their early attempts at diverting the water. At the end of the nineteenth century, frustrated landowners formed a committee and with the help of Theodore Roosevelt came up with a Reclamation Act that took effect in 1902. This Act birthed the Salt River Project a multipurpose project that would generate hydroelectric power, deliver water, and provide flood protection. The Salt River Project was a dream come true, constructing massive dams and canals, that would supply
In the Lake of the Woods is a fictional mystery written by Tim O'Brien. Through the book we learn that our lovers, husbands, and wives have qualities beyond what our eyes can see. John Wade and Kathy are in a marriage so obscure that their secrets lead to an emotional downfall. After John Wade loss in his Senatorial Campaign, his feeling towards Kathy take on a whole different outlook. His compulsive and obsessive behavior causes Kathy to distance herself from him. His war experience and emotional trauma are a major cause for his strange behavior. We remain pondering about Kathy's mysterious disappearance, which becomes fatal for her. Possible scenarios are presented in eight chapters marked 'Hypothesis', these chapters add a mysterious twist which can change our train of thought to 'maybe' or 'perhaps' this is the truth.
The relevant water system in the hydrosphere of the alpine ecosystems is the Snowy River. This is because it is a major river that runs through the Australian Alps in south-eastern Australia. It originates on the slopes of Mount Kosciuszko, Australia’s highest mainland peak, draining the eastern slopes of the Snowy Mountains in New South Wales, before flowing through the Alpine National Park and the Snowy River National Park in Victoria and emptying into Bass Strait.
The movie cited the cause of the global climate change to be the rise in temperature due to greenhouse gasses. The warmer temperatures caused the polar ice caps to melt, and the increased amount of freshwater in the ocean disrupted the North Atlantic Current. The North Atlantic Current is what is responsible for the warm temperatures in the Northern Hemisphere. With the current disrupted the Northern Hemisphere went into an ice age. In real life, the polar ice caps are melting, but at a rate not even close to that of the one represented in the movie. Even if the ice was melting at a quicker rate, the chance that it would throw off the North Atlantic Current is slim to none. Also, there is no way that the ice would melt so quickly that a change that drastic would be made.
An unseen cause of major global climate change is due to the slow shutdown of the thermohaline circulation. Thermohaline circulation is a very slow and deep movement of water in the oceans around the world. A complete cycle can take thousands of years to complete from start to finish. Thermohaline circulation is linked to global climate and ocean health because it mixes dissolved gases and mineral...
