How Does Ocean Level Change

The Sea Level has increased over the past 200 years as average global temperatures have increased. The rise is due to two factors, the freshwater being added to the oceans from ice melt in the cryosphere, and the thermal expansion of the oceans due to rises in sea temperature. The sea level has risen 6 to 8 inches in the past 100 years. It is predicted to rise another 50 to 90 centimeters in the next century. As the sea level rises it’s jeopardizing rapidly growing coastal communities, which causes evacuation in some areas causing people to lose their homes. Sea level is the effect

As it stands today the U.S. coast of the Gulf of Mexico is losing more and more land; the amount of land lost each year may seem relatively small to the average person, but to scientists who understand the unprecedented rate at which this is happening, there is reason to be alarmed. On the U.S. coast of the Gulf of Mexico there are more reasons for the rising sea level than simply global warming and melting ice sheets or ice caps. In the Mississippi delta, for example, the oil industry is taking so much fluid (oil) out of the ground that the land is sinking and compacting further. There is also a decrease in the amount of sediment reaching the delta due to many man-made structures, such as levees, drudging, dikes, and

When the sea level rises, this can be due to multiple factors including climate change and subsidence. Climate change and warming reports identify that “postglacial temperature has increased 13°F in the Gulf region” (Morton 22). This is important evidence because rising temperatures coincide with rising sea levels. As sea water warms, it expands and takes up more room causing sea levels to rise. Additionally, melting glacial ice cause the rise of sea level and is due to climate warming as

The sea-level rise is due to climate change which is caused by rising ocean surface temperatures leads to more evaporation and increase in air moisture. Ocean warming also leads into coral bleaching which results into loss of structure and habitat.

Tectonic activity varies due to geographical location and position of tectonic plate boundaries. The Earth's crust is made up of continental and oceanic plates, which move across the surface of the planet, meeting at plate boundaries. Plate tectonics cause volcanic activity, tsunamis and

According to the American Bar Association, "The National Oceanic and Atmospheric Administration has concluded that during the 20th century, sea levels rose some 5-9 inches throughout the world."(Gresham, Imwalle). This not only puts costal communities at risk of losing their homes, but also cause damage to infrastructures worth millions of dollars. The rise of sea level due to climate change has put Bay Area officials hard at work to come up with different plans on how to deal with this in the future.

With Research shown the late ruin in as costs has turned into a strain on the earth. Not just would this turn out to be awful on our planet however as contamination expands an ever increasing amount, worldwide atmosphere begins to quickly change, ocean level ascent, and more to come. The interest now for this shoddy oil has started to wind up on an unfaltering ascent. This has prompted an immense business sector disappointment. The supply has went up as interest has gone down because of the value change in gas. This would bring about business sector disappointment with a colossal generation a fuel.

The rise in sea level globally is caused by many things the main ones being water added due to land ice melting in Alaska, Greenland and Antarctica due to gravitational effects which has a significant effect on the ocean. With land in the northernmost of Washington rising this causes the relative sea level to fall. However in the rest of Washington, Oregon and California the land is sinking causing relative sea level to rise. and sea water expanding from warming up. In North west America is due to different factors. One of these is the climate aspect where the most important aspect is the occurrence of major El Nino. El Nino involves the Southern Oscillation which affects the winds and ocean circulation this causes the raising of local sea level when there is a warm phase (El Nino) ad lowering of the local sea is during a cool phase (La Nina). With the seasonal variations in the directions and speeds of the shelf currents and the changing directions of the coastal winds. These processes in turn produce seasonal variations in water temperatures.

Dr. Mörner, a sea-level specialist, went to the Maldives to find any sea level trends and that they would go up and down (Murphy). With a varying trend, that meant there was no actual sea rise evidence. He also noted that Maldivian government got mad at him when he claimed on television that there was no sea level rise. Dr. Mörner found out that since they were receiving money from U.S because of CO2 omisson they didn't want to lose that connection. The Maldives is only 1 meter above sea level and is named the flattest country in the world (Union). It’s obvious that a country so flat and little topography will go through a series of floods and harsh storms. In 2004, a tsunami hit the Indian ocean causing destruction to the Maldives structures (Union).The tsunami had nothing to do with climate change and all it did was show how helpless the Maldives is since it mostly made up of coral sands. The opposing viewpoint offers a different perspective to the “problem”. Could the rising sea levels be a coincidence or is it “ a warning sign from mother nature”?

The combination of these and other trends was an estimated average sea-level increase of 1.5mm per year between 1961 and 2003, which reached 2.4mm per year in the decade from 1993 to 2003. The decades prior to this trend showed only minor fluctuations in sea-level, suggesting that the current rate exceeds what could be caused by natural cycles. While the exact impact of rising oceans is difficult to determine, it is certain that the consequences will include some degree of flooding, integration of salt water into water tables, and a loss of land due to coastal erosion and submersion.6

All around the world the tides have a different level that it raises and lowers. The datum used in measuring land elevation and water depths is sea level. Over the past 100 years the sea level has been rising to 1/16 inch per year and in the early 1900s the sea level has doubted to 1/8 inch per year and the current sea level is continuing to rise. As the sea level rises, it changes and affects salt water intrusion, thermal expansion, and the future (Lerner, 2014).

Periods of intense sea-floor spreading causes a rise in sea-level because the less dense lithosphere rising from the spreading

How would you define the term “rising sea levels? Write a definition of the term explaining what it is and how it is going to relate to your topic. You might also want to define global warming and climate change as they relate to rising sea levels. Give examples of places where this has already occurred.

An arc which spreads from New Zealand all the way to the west coast of North and South America where three-quarters of world’s volcanoes are found is called the Ring of Fire. According to the scientists in the video plate tectonics play a very important role in forming of all the volcanoes. The Ring of Fire is also famous for the earthquakes which takes place here. Ninety percent of the world’s earthquakes occur around the Pacific Rim, which is also an aftermath of shifting of plates. The process that moves the rocks and the seawater into the Earth is called subduction. The scientists explained the process of subduction through a 3D picture of the

The oceans have been part of the earth before mankind was even thought of. Greenhouse gas emissions are changing them for the worse. Ocean levels are rising because of the thermal expansion of warming oceans, according to IPCC, this rising can result in many floods across America (Michael). The rising of the ocean can have tragic effects on our economy, meaning that rising in water will result in less area for many shore side organisms. If that's not enough Climate Central predicts that 140-160 million houses and building will be below sea level in a century (Michael).
