Post-glacial rebound (or Glacial Isostatic Adjustment) produces measurable effects on: (i) Vertical Crustal Motion, (ii) Global sea levels, (iii) Horizontal Crustal Motion, (iv) Gravity field, (v) Earth’s rotational motion and (vi) State of stress and earthquakes. Studies of Glacial rebound give us information about the flow law of mantle rocks and also past ice sheet history. The former is important to the study of Mantle Convection, Plate Tectonics and the thermal evolution of the Earth. The latter is important to the study of Glaciology, Paleoclimate and changes in Global Sea Level. Understanding postglacial rebound is also important to our ability to monitor recent global change.To form the ice sheets of the last Ice Age, water is taken from the oceans through evaporation, condensation as snow and then deposited as ice in high latitudes. Thus global sea level would fall during glaciation.The ice sheets at the last Glacial Maximum were so massive that global sea level fell by about 120 metres. Thus continental shelves were exposed and many islands became connected with the continents through dry land. This was the case between the British Isles and Europe, or between Taiwan, the Indonesian islands and Asia. Most important is the existence of a land-bridge between Siberia and Alaska that allowed the migration of people and animals during last glacial maximum.[3]The fall in sea level also affects the circulation of ocean currents and thus has important impact on climate during the Ice Age.During deglaciation, the melted ice water returns to the oceans, thus sea level in the ocean increases again. However, geological records of sea level changes show that the redistribution of the melted ice water is not the same everywhere in the oceans. In other words, depending upon the location, the rise in sea level at a certain site may be more than that at another site. This is due to the gravitational attraction between the mass of the melted water and the other masses, such as remaining ice sheets, glaciers, water masses and mantle rocks[3] and the changes in centrifugal potential due to Earth’s variable rotation.[11]Gravity fieldIce, water and mantle rocks have mass, and as they move around, they exert a gravitational pull of other masses towards them. Thus, the gravity field, which is sensitive to all mass on the surface and within the Earth, will be affected by the redistribution of ice/melted water on the surface of the Earth and the flow of mantle rocks within.Today, more than 6000 years after the last deglaciation terminated, the flow of mantle material back to the glaciated area causes the overall shape of the Earth to become less oblate. This change in the topography of Earth’s surface affects the long wavelength components of the gravity field.The changing gravity field can be detected by repeated land measurements with Absolute Gravimeters and recently by the GRACE satellite mission.[12] The changing long wavelength components of Earth’s gravity field also perturbs the orbital motion of satellites and has been detected by LAGEOS satellite motion.[13]

bundangbear asks the question, Was the Haiti Earthquake caused by HAARP, an antenna system of the United States military, and was an invasion pre-planned, as evidenced by SOUTHCOM’s drill the day before? He also calls to attention the tremendous outpouring of racism he witnessed on YT and the lack of any partner to meet his 20% partner pledge.

http://RevolutionNews.us — January 2010 — Bush was responsible for destroying Haitian democracy. Clinton has largely sponsored a program of economic development that supports the idea of sweatshops.In addition to providing immediate humanitarian assistance, the U.S. response to the tragic earthquake in Haiti earthquake offers opportunities to re-shape Haitis long-dysfunctional government and economy as well as to improve the public image of the United States in the region.Reshape it how? Well, those who remember how Heritage responded to Hurricane Katrina will probably get it about right. In 2005 Heritage applauded Bush for suspending provisions of the Davis-Bacon Act, so that federally funded Gulf Coast construction projects could pay lower-than prevailing wages.As Naomi Kleins described in her bestseller The Shock Doctrine: The Rise of Disaster Capitalism, no disasters too disastrous to become a useful Petri Dish for the conservative corporate agenda. And no times too soon to start drawing up quids pro quo. Well give you a quid if you become more pro-our-quo. In 2005, it took Heritage almost two weeks to get their word out. This time around, as Klein pointed out in a forum Wednesday night, they were out with a statement within hours.Just two months back, Secretary of State Clinton was promising aid for countries suffering climate change, as long as the countries in Copenhagen agreed to the U.S.s terms. As irony would have it, the Secretary of States husband, Bill Clinton, now the US emissary to Haiti, oversaw a punishing regime of structural adjustment imposed on Haiti on his watch, in exchange for a US backed return of democratically elected president Aristide.You need help? Youll get it, the IMF (and Clinton) said, if you privatize your water, lay off public workers and shrink the public sector. Theres no mystery about the countrys paucity of first responders.Naomi calls it blackmail. The power that comes when youre giving money to people in need. Were likely to see a lot of it in Haiti now, especially if the Heritagers have their way. Oddly, its a power the Treasury didnt use when it came to bailing out big bankers, pointed out Klein Wednesday night.What are the chances, do you think, that the US Treasury will be as generous with Haiti as they were with Wall Street?Repost this video – the MSM is ignoring the Haitian / US History!http://www.thenation.com/blogs/notion…Time For A New Revolution?♥☠✿☮❀☠✿☮❀☠✿♥❀☠✿http://RevolutionNews.us♥☠✿☮❀☠✿☮❀☠✿♥❀☠✿
