The Nature of Geography What Do Geographers Do? Volcanologist A volcanologist is a geographer who specialises in working with volcanoes. Their responsibilities range from observing volcanic eruptions‚ to monitoring volcanoes‚ to analysing samples of rock from volcanoes and even predicting when the next eruption of a dormant volcano may occur. In a typical day of a volcanologist‚ one analyse data collected by others and manipulate it with the use of a computer. On the other hand‚ a volcanologist

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

Seas and oceans provide various types of resources to human beings and habitats to numerous species of plants and animals. They play very important roles in the economy of a nation and its people. Still‚ the marine and coastal ecosystems are under severe stress due to human activities. Ocean Resources 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

All unnatural material that finds its way to the world’s seas is classified as ocean pollution‚ however these materials built up over time. This process is known as bioaccumulation. There are many contributing pollutants to bioaccumulation in oceans such as toxins‚ marine debris‚ oil‚ sewage‚ eroded soil‚ and heavy metals. In the past‚ dumping small amounts of pollutants into the oceans‚ known as dilution‚ was not thought of to be a threat to the environment because all of the oceans combined

Ocean Pollution It is believed that 4.6 billion years ago our Earth was formed. And over 200 million years ago the great body of water on this planet‚ what we call the ocean‚ was able to be formed (History of the Ocean). For 200 million years our ocean has flourished with the life of all matters of creatures from some of the first ever cells to take life‚ to pre-historic dinosaurs‚ to the fish‚ plants‚ and mammals we see today. However‚ today we face a new point in the history of our ocean. Today

Acidification in our Oceans Oceanography April 2‚ 2013 What is Ocean Acidification? “Ocean Acidification‚ is the worldwide reduction in the pH of seawater as a consequence of the absorption of large amounts of carbon dioxide (CO2) by the oceans.” (Britannica). Ocean acidification is largely the result of loading Earth’s atmosphere with large quantities of CO2‚ produced by vehicles and industrial and agricultural processes. Since the beginning of the Industrial Revolution about

Introduction Oceanography‚ the study of the ocean‚ was first studied in pre-historic times out of curiosity about the regions underneath the ocean surface as well as waves‚ the rise and fall of the tides‚ and other coastal processes. The word oceanography is a compound of two Greek words meaning ‘ocean’ and meaning “to write’. The Phoenicians‚ Greeks‚ and Romans were in fact our first oceanographers. In 7250 B.C. the first recorded sea voyage took place in the Aegean. There is evidence of sea trading
