Environmental and political concerns are just two reasons why alternative energy sources, such as ocean energy conversion, need to be considered. Overview of Ocean Energy Conversion Technologies Technologies that currently exist for generating electrical power from the oceans can be grouped into six broad categories: thermal energy, tidal power, wave power, ocean currents, ocean winds, and chemical sources. According to Ron Bregman, an Ocean Resource Engineer, the most promising and well-developed of these technologies are thermal energy, tidal power, and wave power (1996). Thermal Energy The oceans are the world’s largest solar collectors. Each day the oceans absorb an amount of solar radiation equivalent in heat content to about 250 billion barrels of oil, according to Michael Champ in Sea Technology (1995).
The remaining carbon usually gets absorbed by the oceans. 90 percent of the effects of global warming are attributed to rising temperatures and heat. This heat tends to affect our oceans due to the ... ... middle of paper ... ...and production is thought to be one of the leading causes of this pollutant in the atmosphere. Taller smoke stacks on factories manage to carry the pollution farther away from nearby populations, but in doing this they also manage to carry the pollutants to a much wider range. The chemicals can be carried high and far into the atmosphere and can be deposited in areas far from the initial source of the pollution.
The California coast is a thriving ecosystem, both beneath the sea and in the cities that line its shore. For the purposes of our discussion, we will focus on mussels as an example species. Mussels, as we speak are being harmed by ocean acidification, and the damage is becoming more and more costly to our ecosystem. Global climate change, more commonly referred to as global warming, is an important factor in ocean acidification. At its most basic, climate change is the result of previously unheard of levels of carbon dioxide entering the atmosphere and creating a greenhouse effect within the earth’s atmosphere.
If you know more about oceans you will be able to understand the importance of it, and that will lead you to protect the ocean. You can start reading about the causes that make a damage to our ocean, also you can aware your self by reading about the solutions of it. Oceans takes a large amount of the earth, if less people knew about the importance of ocean, then we will be probably in danger. However, we can’t live without oceans, and we must learn about how much we depend in oceans from livelihood and nutrition, to relaxation and hobbies. “Scientists believe that life on Earth began in the ocean, approximately 4 billion years ago.
In the past age, there were many explorations into the deep sea. Scientists originally descended in order to find the kraken and the giant squid. In the modern era, scientists travel to the deep to discover slightly smaller creatures. Microbial organisms are the most abundant life form on Earth. Scientists drill for microbes on the ocean floor where ancient remains still exist.
The non-profit organization Oceana has worked to protect and restore the world’s oceans since 2001 with a focus on international conservation. Their mission statement is as follows: Oceans cover 71 percent of the globe, and they are as important to us as they are vast. Our oceans are home to most of the life on our planet and play a central role in the world's natural systems…They provide livelihoods to countless fishermen and others…they also feed hundreds of millions of people…Unfortunately, the oceans are in trouble… [but] we know how to fix things. Science-based fishery management…is helping the oceans rebound and recover where it is established. Oceana is dedicated to advocating for science-based fishery management and restoring the world's
Climate Change Introduction What is the oceans role in climate? The oceans play a vital and pivotal role in the distribution of life sustaining water throughout our planet. 86% of the evaporation that occurs on earth is over the oceans. The oceans are the planets largest reservoir of water transferring huge amounts of water around the hydrological cycle. In fact the oceans “dominate the hydrological cycle, for they contain 97% of the global water inventory” .
A large proportion of all life on Earth exists in the ocean. Exactly how large the proportion is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering about 71% of the Earth's surface. Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world. At a fundamental level, marine life helps determine the very nature of our planet.
Natural Resources and Environmental Features The environment has been a very important aspect when it comes to power. The natural resources you can find in our environment have been used to advance and secure political, economic and social power. Most of the issues relating to our environmental features are climate change. Climate change is a factor of any power, but mostly socially. Climate change has brought together numerous countries to make a plan of action and to act on it.
Water takes up a larger percentage of the surface of our Earth than does land. The earth’s oceans are vital aspects to our environment and it is necessary that we take care of them. On another note, global warming is an issue that is having effects on almost all aspects of our environment. Global warming itself means a gradual increase in the temperature of our Earth’s atmosphere over large periods of time. There is evidence that global warming has occurred in the atmosphere, however, now we are beginning to see its effects in the world’s oceans, as well.
