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

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

Plastic in Our Oceans 46‚000 pieces of plastic per square mile make up 90% of our ocean’s trash accumulation (Nichol‚ 2012‚ Plastics‚ like Diamonds‚ are forever‚ para. 1). Within the areas‚ many animals will either ingest‚ become entangled in‚ or even die due to the high plastic amounts. Nearly 267 species are harmed by plastic (Nichol‚ 2012‚ Fast Facts). With such deadly effects due to yearly accumulation‚ the banning of plastic bags and reduction of usage in a household will improve overall health

The Ocean Ranger The Ocean Ranger was an offshore exploration oil drilling platform that sank in Canadian waters 315 kilometres southeast from St. John’s Newfoundland‚ on the Grand Banks of Newfoundland on February 15‚ 1982‚ with 84 crewmembers onboard. The Ocean Ranger was the largest semi-submersible‚ offshore exploration‚ oil drilling platform of the day. Built in 1976 by Japan’s Mitsubishi Heavy Industries‚ it operated off the coasts of Alaska‚ New Jersey‚ Ireland‚ and in November 1980 moved

Imagine being a little kid‚ playing in the ocean. All the waves are crashing and you are jumping over them. Suddenly‚ you see a large amount of trash‚ beer bottles‚ plastic containers‚ and strings that hold all of it together. You remove the trash from the ocean and put it into a trashcan. By this small task‚ you have supported the sustainability of the ocean. “Sustainability is ensuring that critical social‚ economic‚ and ecological processes are maintained in a way so that both the short and long-term

Ocean Current and Global Weather The ocean is the largest habitat for life on earth‚ and is vital to the land habitats as well. The ocean regulates the earth’s weather patterns. The main force influencing global climate is the solar energy of the fun. Because the earth is a sphere its surface is not heated equally by incoming solar energy. The equatorial areas receive more sunlight while the poles receive less because sunlight strikes at an oblique angle so much of the sunlight are reflected away

Part 1: 1. Describe four factors that influence ocean currents. There are many factors that influence ocean currents‚ four of the factors would be planet rotation‚ wind‚ density of water‚ and gravitation. Planet rotation causes the currents to move clockwise in the northern hemisphere and counter clockwise in the southern hemisphere. Wind blows on the surface of the ocean therefore pushing the water in the direction of the wind. Different densities in the water can cause currents to form and move

that comes along with this aspect of climate change. So what causes the ocean to continue rising? Two answers that seem to stand out are polar ice melting‚ therefore increasing the amount of water in the oceans‚ and the sinking of ground sediment. The latter reason is not as well emphasized‚ but still remains a pressing issue that our civilization needs to come face to face with. Along with the obvious rise in the ocean waters‚ coastal populations also face events brought on by nature such as

Opened in 1977‚ Ocean Park Hong Kong is one of Hong Kong’s favourite attractions‚ featuring rides‚ exhibits and conservation facilities. Ocean Park is located on the southern side of Hong Kong Island‚ covering more than 870‚000 square metres of land.
