Ocean Ice Research Paper

Coastal cities all around the world are quite precious to the countries to which they belong. Small and large cities on the water can accumulate massive amounts of income for countries, with most of it coming from tourists. Unfortunately, these cities are at risk of shrinking in size as a result of rising seawater levels. Along with less land for those cities to bring in money, it would cost millions of dollars to relocate the buildings and homes built there. Due to rising average temperatures of the earth, thermal expansion of water, along with melting ice caps, is causing the seawater levels to rise, which is threatening coastline cities such as New York City and Venice, Italy.

Since the industrial revolution, scientists have documented a trend of increasing atmospheric carbon dioxide (CO2), the main greenhouse gas. This observation has been an issue of major environmental concern in the view of the potentially devastating effects of climate change on ecosystems and human survival. Recent studies by scientists led by Wei-Jun Cai have served to underscore this fact by showing that the Arctic region and the globe are faced with a major climate challenge due to the continued melting of sea ice in the Arctic Ocean. This research has indicated that the major concern is the increasing heat absorption as deeper ocean water layers get exposed to sunlight as well as the possible loss of white ice reflectivity or the

For many years now, scientists have believed that our climate is changing. This climate change has caused water currents up north, near Antarctica to shift leading to warm waters taking the place of the usual cold arctic waters. Warm water melts the glaciers and causes the top of the glaciers to float off into the sea, allowing the warm water to melt even more glaciers. The extra glacier melting into our sea has caused the sea levels to raise and the

In recent months, scientists have been taking notice to record cool temperatures observed in the North Atlantic Ocean, while the rest of the world is experiencing record warmth. They believe this cooling of the water to be due to the accelerated melting of the Greenland ice

The Arctic Ocean is of little depth. It is the smallest ocean compared to the world's 5 major oceans. Although, we consider it as an ocean, some oceanographers would simply state it as a sea. Since The Arctic Ocean is small and shallow you would understand why some would recognize it more as a sea instead of an ocean. Its is obviously cold, freezing if you would prefer to describe it that way. It is moderately covered by sea ice throughout the year. In winter it is almost completely filled with sea ice. Did you know the Arctic ocean surrounds the North Pole.

As more of the sun’s energy is retained by increasing greenhouse gases, the earth’s oceans are heating up. This can be seen by an increase in average water temperature and warm water anomalies (water temperature over the average).

Why don’t Oceans freeze. In many parts of the world , winter temperatures drop low enough to make rivers and lakes freeze. In these parts of the world, the ocean will not freeze even though other water sources does. In the Arctic region, most of it is a tundra, which include frozen soil and animals such as polar bears and penguins. The ocean however is not frozen.

Warming seas and melting ice are the consequences of global warming which is the heating of Earth caused by greenhouse gasses trapped in Earth’s atmosphere. Global warming causes the heating of Earth’s seas, and when the water molecules in these bodies increase in temperature, they thermally expand which causes the sea to rise. The heat is also causing the melting of Earth’s ice sheets, and when the ice turns to water, it causes the sea to rise as well. Note that the water does not rise evenly. The sea level may increase in some areas as it may decrease in other areas. Sea level rise is inevitable because of the greenhouse gasses that are trapped in the atmosphere, they will always increase sea level to some degree. However, the decisions we

The Arctic Ocean is some five million square miles of barren ice and frigid water roughly the size of Russia that lies at northernmost point of our planet. However this portion of the planet is soon to be one of conflict, to be fought with words and lengthy jurisdictional claims, as the Arctic contains portions of Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden, and the United States. But who would want this megalithic ice flow and swath of ocean? Due to climate change the Arctic has begun to reveal its potential as a vast petroleum and natural gas source (estimated to be an eighth of the world’s untapped oil and a quarter of its gas by the USGS) and the location of valuable shipping routes between China and Europe. However there

First of all, the world’s oceans have increased in temperature. According to www.nasa.gov, the “Ocean (has warmed up)... 0.302 degrees Fahrenheit since 1969” Basically, the ocean has warmed up an average of 0.006 degrees per year, and although it is not a very noticeable amount, temperature can increase the risk of more water related natural disasters. For instance, the 2017 Atlantic Hurricane Season was very intense. One example from the website www.cnn.com mentions there were over 17 storms that may have developed into hurricanes between June and November. On the other hand, scientific studies determined that Antarctica had record ice in the year of 2014.

Antarctica is covered in ice that is two miles thick in some places. Thousands of years ago, there was thick ice that covered this area, that moved back hundreds of miles to where it is now. Using maps, scientists at Rice University were able to show how ice had moved during a time of global warming during the earth’s last ice age. These maps also showed where ancient water courses, like rivers and lakes, once were.

As snow and ice melt, ocean surfaces absorb Sun’s energy, increasing warming. Ice normally would reflect light.

In November of 1978, NASA used satellites to track climate change. Then in 2013, Claire Parkinson did a study about the change in the quantity of ice. She finds in her studies that the ice has gone away dramatically at a steady rate. The fresh water inside these capes are melting and in turn the ocean levels are rising. Sea ice has be disappearing in all parts of the Artic. Even though ice has been returning in the Antarctic it will not be enough to make up for all of the ice dissipating. Annually the heat from the greenhouse effect has made the ice caps lose an average of 13,500 square miles since 1979. All of that water is being put back into the ocean therefore the tides are becoming bigger and

If Earth’s surface is warmed enough, it will also start to warm the bodies of water. The heating waters are currently the reasons for the melting of ice shelves. Luckily, the ice shelf melting is not as serious due to the water flowing and refreezing ("Global Climate Change: Research Explorer”). However if the ice shelves are melting too fast then that could cause complete changes in glaciers and the land mass in general. With the loss of land mass from mainly Antarctica, it means a rise in sea levels.

As oceans are warming, the planet’s ocean and glaciers have also experienced changes. Glaciers, and Ice caps are melting, thus with the melting of the glaciers and ice caps, the sea levels are rising. Large bodies of water, like rivers and lakes are also drying up and disappearing. Scientists predict that these and other changes are going to become more pronounced in the coming decades.
