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

Ocean dumping Ocean Dumping The practice of ocean dumping should be banned. Marine pollution is at the heart of interest in today’s search for a clean environment. Not only does ocean dumping add to the unsightliness of the once beautiful and pristine waters; it also kills the marine life which inhabits those waters. Pollution on a grand-scale is wreaking havoc on the Earth. The ocean is not an exception. In 1996‚ a bill‚ which would ban the dumping of dredge spoils in the Long Island Sound‚ was

Although both rely on the movement of the earth’s ocean‚ they use the kinetic energy produced to manipulate the movement into an energy source. keywords: sustainable‚ renewable‚ energy‚ resources Table of contents Introduction ……………………………………………….……pg 4 Chapter

Did you know that most of the ocean pollution comes from us? This pollution can hurt the ocean animals and it will affect the food that we eat. Some of the most worst ocean pollution is untreated sewage dumped into the ocean‚ toxic chemical‚ and oil spills. The sewage gets into the ocean because of sewage pipes that break or leak. This is a problem because the sewage makes to much algae‚ and it will remove the oxygen. Around 80% of the sewage that is in the ocean is untreated. To help stop sewage

The Ocean Specific Purpose: To inform my audience about the ocean and the benefits the ocean has on us. Central Idea: We have not discovered a majority of the ocean and I wanted to share why we have not done that. To inform that the ocean is very valuable and that we need to spend more time on really discovering what is down there. Introduction I. The ocean covers more than 70% of the planet’s surface. II. 95% percent remains unexplored‚ and unseen by the human eye. III. Over one million

Ocean Acidification and its Effects on Marine Butterflies and Coral Reefs For millions of years‚ Earth’s oceans have maintained a relatively stable acidity level. Research shows that a recent and rapid drop in surface pH that could have devastating global consequences through the unbalance the ocean’s acidity. Since the beginning of the industrial revolution in the early 1800s‚ fossil fuel-powered machines have created a burst of industry and machines. The consequence of this industrial revolution

Sea Pollution The pollution of the ocean is rapidly becoming a crucial problem on Earth. The major causes of sea pollution are oil spills‚ toxic waste‚ and dumping of other harmful materials into the ocean. This pollution will directly affect the living organisms in the ocean and indirectly affect human’s health and resources. We‚ as humans‚ should learn more about these in order to have the knowledge on how to solve this problem effectively. Oil spill is perhaps the most publicly acknowledged
