Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans‚ caused by carbon dioxide from the atmosphere‚ Seawater is slightly basic (meaning pH > 7)‚ and the process is a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7). Ocean alkalinity is not changed by the process‚ or may increase over long time periods due to carbonate dissolution. An estimated 30–40% of the carbon dioxide from human activity released into the atmosphere dissolves into

The ocean appears to be a large trash can for disposing waste in the convenience for humans. According to UNESCO‚ statistics show that in 2006‚ 46‚000 plastic materials were found scattered every square mile in the ocean; in addition to that statistic‚ millions of marine animals are severely injured or even fatal

Vaughn‚ par 9). For generations the ocean has been called “The largest museum on earth” (Vaughn‚ par 8). The Earth has been maintained in a natural state of balance‚ but the advancement of human civilization has thrown it off balance (Stewart‚ video). Each year as humans evolve we destroy the Earth along with its natural resources (Rekacewicz‚ par1). Almost everything depends on water and it’s cycle. However‚ the oceans

Keeping oceans young and productive: - Upwelling and Downwelling Oceans cover two thirds of our planet thus they can be regarded as one of the major factors in shaping this blue marble in space. But oceans just don’t result in varying gradient of humidity that gives rise to different vegetations and ultimately widely different biomes when coupled with other factors such as differential exposure to solar radiation‚ and inherent soil type. Oceans are living systems that themselves support numerous

OCEAN ACIDIFICATION The world’s oceans have largely been left out of the mainstream discussion of global climate change. Yet‚ as one of the largest natural reservoirs of carbon‚ the surface ocean plays a critical role in the global carbon cycle. Over recent years‚ human activities such as the burning of fossil fuels have increased the amount of carbon dioxide gas emitted to the atmosphere and the amount that dissolves into the ocean. Over the last decade‚ scientists have discovered that this excess

The ocean as vast and as mysterious as it is‚ is facing problems caused by humans dumping waste into it and that is causing marine life to be harmed. It was thought that the ocean was so deep and huge that no matter how much garbage you put into it would have small consequences. As we have seen that is very wrong‚ here are a few of the problems ocean pollution cause: Toxic metals can destroy the biochemistry‚ behavior‚ and reproduction of marine life. Fertilizer runoff creates eutrophication that

Ocean Pollution is Destroying the World We are constantly polluting the ocean never realizing the harm that it does. Pollution is creating an environment impossible to live in. Why should animals suffer at our expense? The ocean used to be the most beautiful place in the world‚ filled with life and color‚ but now it has turned into a trash filled monstrosity. We are constantly putting more and more trash into the ocean‚ making marine animals live in our filth. We must end pollution to save our world

Ocean acidification is caused by CO2 in the atmosphere when it reacts with water it creates carbonic acid. It’s a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don’t see or feel because its effects are happening underwater. When carbon dioxide is absorbed by seawater a chemical reaction occurs that reduces the seawaters pH‚ carbonate ion concentration‚ and saturation states of biologically significant calcium carbonate minerals. It decreases the pH of seawater

CHAPTER 31 OCEAN CURRENTS TYPES AND CAUSES OF CURRENTS 3100. Definitions The movement of ocean water is one of the two principal sources of discrepancy between dead reckoned and actual positions of vessels. Water in motion is called a current; the direction toward which it moves is called set‚ and its speed is called drift. Modern shipping speeds have lessened the impact of currents on a typical voyage‚ and since electronic navigation allows continuous adjustment of course‚ there is less need to
