The Great Lakes

Examples of The Great Lakes in the following topics:

• Extremely Halophilic Archaea

  • In fact, the very name "halophile" comes from the Greek word for "salt-loving. " Although some halophilic bacteria and eukaryotes exist, the largest classification of halophiles is in the Archaea domain.
  • Halophiles thrive in places such as the Great Salt Lake , Owens Lake in California, evaporation ponds, and the Dead Sea - places that provide an inhospitable environment to most lifeforms.
  • Halophiles prevent this loss of water by increasing the internal osmolarity of the cell.
  • These are the primary inhabitants of salt lakes, inland seas, and evaporating ponds of seawater.
  • Halophiles are adapted to conditions of extreme salt concentration, such as the Great Salt Lake in Utah.

• The British Strategy

  • Throughout the war, the British Secretary of State for War and the Colonies was the Earl of Bathurst.
  • A decisive use of naval power came on the Great Lakes and depended on a contest of building ships.
  • The U.S. started a rapidly-expanded program of building warships at Sackets Harbor on Lake Ontario, where 3,000 men were recruited, many from New York City, to build eleven warships early in the war.
  • In 1813, the Americans won control of Lake Erie in the Battle of Lake Erie and cut off British and Native American forces in the west from their supply base.
  • Control of Lake Ontario changed hands several times, with both sides unable and unwilling to take advantage of the temporary superiority.

• Site-Specific Art

  • Typically the artist takes the location into account while planning and creating the artwork.
  • His most famous work is Spiral Jetty (1970), a 1,500-foot long spiral-shaped jetty extending into the Great Salt Lake in Utah constructed from rocks, earth, and salt.
  • It was entirely submerged by rising lake waters for several years, but has since re-emerged.
  • Spiral Jetty is a site specific piece of Land Art or Earth Art created by Robert Smithson in the Great Salt Lake, Utah.
  • Using rocks and earth, Smithson built up a spiral shaped relief in the lake bed.

• The War in the North

  • The seizure of American ships and sailors, combined with the British support of American Indian resistance, led to strident calls for war against Great Britain.
  • Joseph Island, on Lake Huron, learned of the declaration of war before the nearby American garrison at the important trading post at Mackinac Island in Michigan.
  • This early victory encouraged American Indian resistance, and large numbers moved to help the British at Amherstburg (near the western end of Lake Erie).
  • A decisive use of naval power came on the Great Lakes and depended on a contest of building ships.
  • In 1813, American Captain Oliver Hazard Perry and his naval force won control of Lake Erie in the Battle of Lake Erie, cutting off British and American Indian forces in the west from their supply base.

• Freshwater Biomes

  • Light can penetrate within the photic zone of the lake or pond.
  • At the bottom of lakes and ponds, bacteria in the aphotic zone break down dead organisms that sink to the bottom.
  • As a result, the lake or pond becomes aphotic: photosynthetic plants cannot survive.
  • Here, a great egret walks among cypress trees.
  • The uncontrolled growth of algae in this lake has resulted in an algal bloom.

• Architecture of the Aztecs

  • Their capital was Tenochtitlan on the shore of Lake Texcoco, the site of modern-day Mexico City.
  • An ancient Aztec prophecy predicted that the wandering tribes would find the destined site for a great city.
  • The Aztecs saw this vision on what was then a small swampy island in Lake Texcoco.
  • Surrounding the city and floating on the shallow flats of Lake Texcoco were enormous chinampas—long raised plant beds set upon the shallow lake bottom.
  • The Great Temple measured approximately 328 ft by 262 ft at its base, dominating the Sacred Precinct.

• Loss of Biodiversity

  • Human activity is the driving force behind the current biodiversity crisis, which is causing great species loss in a short time period.
  • The Lake Victoria cichlids provide an example through which we can begin to understand biodiversity.
  • The cichlids of Lake Victoria are the product of an adaptive radiation.
  • A culprit in these declines was a species of large fish that was introduced to Lake Victoria by fisheries to feed the people living around the lake.
  • These factors included not only the Nile perch, but also the declining lake water quality due to agriculture and land clearing on the shores of Lake Victoria, and increased fishing pressure.

• Logic

  • Instinct, intuition and introspection were once of great importance, but are not often seen as credible as "science" when seeking justifications for "knowledge" in Western, industrial societies.
  • If the general principle or major premise were that all the water in the lake was safe to drink, then deductive reasoning would conclude that a specific glass of water from the lake (the minor premise is the water is from the lake) is safe to drink.
  • If several glasses of water were taken from a lake and each glass of water was shown to be safe to drink, it might be "inferred" that the water in the lake is safe to drink.
  • Because all the water in the lake was not (and possibly could not) be tested there is some probability that all the water in the lake is not safe to drink.
  • The selection of which phenomena to observe and the sequencing of the "facts" can alter the conclusions reached.

• Energy Sources

  • The water at the bottom of the lake, displaced by the heavier surface water, rises to the top.
  • As it rises, the sediments and nutrients from the lake bottom are brought along with it.
  • During the summer months, the lake water stratifies, or forms layers, with the warmest water at the lake surface.
  • The oxygen-rich water at the surface of the lake then moves to the bottom of the lake, while the nutrients at the bottom of the lake rise to the surface ().
  • The spring and fall turnovers are important processes in freshwater lakes that act to move the nutrients and oxygen at the bottom of deep lakes to the top.

• The Mormon Exodus

  • The Mormon exodus of 1846-47 was a large migration of members of the Church of Latter Day Saints from their home in Illinois to Salt Lake Valley, Utah.
  • The Mormon Trail extends from Nauvoo, Illinois, which was the principal settlement of the Latter-Day Saints from 1839 to 1846, to Salt Lake City, Utah, which was settled by Brigham Young and his followers beginning in 1847.
  • The Mormon exodus began in 1846 when, in the face of these conflicts, Brigham Young (Joseph Smith's successor as President of the Church) decided to abandon Nauvoo and to establish a new home for the church in the Great Basin .
  • In the spring of 1847, Young led the vanguard company to the Salt Lake Valley, which was then outside the boundaries of the United States and later became Utah.
  • Also shown are a portion of the route followed by the Mormon Battalion and the path followed by the handcart companies to the Mormon Trail.
