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

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.

deep ocean The oceans cover 75% of the world’s surface and contain 97% of its water; 90% of the seas lie beyond the shallow continental margins‚ and most are deeper than 2km. With the advent of modern science we have been able to discover what some of the deep ocean is like but there is still a vast area that remains unexplored. One thing we do know is that life at these depths is dominated by animals‚ not plants

Why do I do it? Why do I scare myself with the ocean…? It is true‚ it is merciless‚ literally; it’s not conscious‚ so it has no feelings‚ no remorse‚ no pity‚ no awareness. It would be wrong to say it is inanimate‚ because it is certainly animate. And not alive‚ yet contains so much life within it might as well be. Like a Frankenstein body filled with cells and bacteria and nerve impulses yet no consciousness. My worst nightmare – I don’t have it very often but it’s a strong one – can take

The deep sea is the darkest region of the ocean‚ where sunlight fades to blackness and plants cannot grow. It covers more than half the planet‚ and encompasses nearly 98% (by volume) of all living space on Earth. The harsh and extreme conditions of the deep ocean-crushing pressure‚ corrosive salt water‚ and freezing temperatures have made deep sea exploration nearly as challenging as space exploration‚ and nearly as infrequent. Until recently the deep ocean was thought to be almost completely

SALINITY AND DEEP OCEAN CURRENTS OVERVIEW Ocean currents arise in many different ways. For example‚ wind pushes the water along the surface to form wind-driven currents. Deep ocean currents are caused by differences in water temperature and salinity. In this experiment‚ the students will hypothesize the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents. CONCEPTS Salt water is more dense than fresh water‚ and is therefore

Hossain Descriptive Essay July 2‚ 2013 The Ocean The ocean‚ from the Pacific to the Atlantic and the Indian to the Artic‚ is a vast and enchanting part of our world. The oceans of this world cover more than sixty six percent and that number is steadily rising. There are so many facets of the ocean that are yet to be discovered‚ but as someone who lives fifteen minutes away from a beach‚ it is hard not to be intoxicated by the allure that the ocean draws. Oceans have their own smell‚ feel‚ taste and sound

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
