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

has been around for centuries. Currently there are only a few different types of hydro power used to produce energy‚ and only 2 will be covered in this research: wave/current energy & tidal energy. 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

The ocean is one of Earth’s most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It’s used for transportation—both travel and shipping. It provides a treasured source of recreation for humans. It is mined for minerals (salt‚ sand‚ gravel‚ and some manganese‚ copper‚ nickel‚ iron‚ and cobalt can be found in the deep sea) and drilled for crude oil. The ocean plays a critical role in removing carbon from the atmosphere and

An Ocean Habitat or sometimes refer to as a marine environment is a place in the ocean where plants and animals interact with the chemical and physical features of the environment. An Ocean habitat is a place where communities of organisms live. The three main ocean habitats of the ocean are the open water‚ the soft sandy to muddy bottom and the hard shore. Examples of ocean habitats are the coral reefs‚ the estuaries and the abyssal zone. Habitats can be classified in a number of ways in order

Ocean Pollution “Over 80% of marine pollution comes from land-based activities” (WWF‚ May 4‚ 2006‚ p.1). The rest comes from ocean-based activities. Different types of pollution enter the ocean each year. The major pollutants are oil‚ toxic materials‚ and debris. These materials not only pollute the ocean‚ but they also affect the marine life. Before the 1970s there were no laws to prevent and stop people from dumping pollutants into the ocean. Since the early 1970s many laws and regulations

The Blues is a musical form and genre‚ which originated in South America within the African-American communities.

When one thinks of very large bodies of water such as the ocean‚ we are talking about marine biomes. Instead of freshwater it contains saltwater. They also include the coral reefs and estuaries. The ocean biome is the largest of all of the worlds. Which makes sense considering that the majority of the world surface is made up of water. Due to

The Ocean Floor No one has ever walked the sea floor and few have even seen it. This is because of the extreme conditions found there. It is dark‚ and the temperature is close to freezing. A person standing on the sea floor would be under tremendous pressure from the overlaying water. The pressure is hundreds of times greater than the atmospheric pressure. Such a force would crush the human body. Using research submersibles which are specially designed to with stand the pressure of the water‚ scientists
