OCEANS AND THEIR COASTAL MARGINS: Distributions of oceans and ocean currents Distribution and Importance of Oceans: Oceans cover about 70% on the earth’s surface Great importance to humans in number of ways‚ include: regulating global climates and as a source of economic materials. Oceans are also important for leisure and recreation Oceans cover about 50% of the earth’s surface in the northern hemisphere and about 90% in the Southern hemisphere Ocean / Sea Area in 1000km^2 Pacific

Ocean Acidification The main theme of the 3 articles is that the ocean is becoming more acidic due to fossil-fuel emission of CO2. The ocean has absorbed about 525 billion tons of carbon dioxide from the atmosphere‚ this reduces the amount of greenhouse gas in the atmosphere (1). ). It is lowering the pH by .1 units changing it from 8.2 to 8.1… it is becoming more acidic. (2). It happens when the CO2 from the air mixes with the sea water‚ it produces a bicarbonate ion. This bicarbonate ion then

Ocean Noise Pollution For millions of years‚ the oceans have been filled with sounds from natural sources such as the squeaks‚ moans and clicks of whales and dolphins‚ the snapping of shrimp‚ the sound caused by wind upon the surface and even the occasional rumble from earthquakes. Over millions of years‚ the ocean’s marine species have developed into what they are today‚ with their own specialized acute hearing abilities‚ communication skills and echo location abilities at natural sound levels

Though humans have gotten better about keeping pollution out of the environment‚ pollution is still a very predominant problem. Ocean pollution is one of the less talked about problems‚ because mankind knows so little about the ocean. However‚ it is still a major issue. Oil has been a sizable cause of marine pollution. It causes problems to the plants and animals of the ocean‚ as well as affecting oceanic movements and even human life and activity. Though oil is an important part of human life‚

The sun was shining‚ the wind flowing through the air‚ and the waves were crashing onto the shoreline. The seagulls were roaming around trying to search for nourishment. As I step into the Atlantic Ocean I feel the sand between my toes and the water streaming around my body. I gazed at the horizon. The only thing I could see was the luminous sun and blue sky. The brisk water proceeds up my legs and to my torso as I stroll into the water. I submerged into the water and opened my eyes. All I could

2012 Sensing The Atlantic Ocean. Who would have thought an unplanned vacation would turn out to be one of the best vacations ever? My parents surprised me with a flying ticket to go to Florida‚ on August 4‚ 2012‚ with my cousin Oscar. According to Oscar’s parents and my parents: it was our graduation present (since we are the first cousins on our family to graduate). I will be sharing my experience on seeing‚ smelling‚ touching‚ tasting‚ and hearing the Atlantic Ocean. They say Florida

Will the Atlantic Ocean ever be bigger than the Pacific Ocean? The earth first started off as one huge continent called Pangea. Pangea was surrounded by one giant body of water. Over the course of millions and millions of years‚ Pangea began to break off and separate. After millions of years of movement‚ that is why the earth has the formation that it currently has‚ with seven large continents. With an area of 41‚105‚000 square miles‚ the Atlantic Ocean is currently just a little over half the

Thermohaline Ocean Circulation #1- What is The Thermohaline Ocean Circulation concept? The Thermohaline Ocean Circulation is when the circulation of the ocean is caused by heat and freshwater in the sea’s surface. This causes the mixing of heat and salt in the ocean. Thermo is temperature and haline is salt. Temperature and salt are the two factors that determine the sea’s density. The circulation causes differences in seawater density. The circulation also causes warm water from the southern hemisphere

Journey to the Ocean Floor Oceanography is a science that draws upon the methods and knowledge of geology‚ chemistry‚ physics‚ and biology to study the ocean. The Pacific Ocean is the largest and the deepest ocean. Most submersible dives follow a similar pattern‚ emphasizing bottom transecting‚ collecting and photographing specimens. To understand our ocean floor exploration‚ you must first know something about the ocean floor. Follow along below as I summarize the parts of the ocean floor.

A lake is a body of relatively still water of considerable size‚ localized in a basin‚ that is surrounded by land apart from a river‚ stream‚ or other form of moving water that serves to feed or drain the lake. Lakes are inland and not part of the ocean and therefore are distinct from lagoons‚ and are larger and deeper thanponds.[1][2] Lakes can be contrasted with rivers or streams‚ which are usually flowing. However most lakes are fed and drained by rivers and streams.Natural lakes are generally
