Oceanography is a broad field of research that includes fields of study such as physics, chemistry, biology and geology. Oceanographers utilize their branch of specialization to study the oceans of the world, their biological diversity, chemical composition, structure and formation, among others. Many scientists studying...
Types of oceanographers
By: Menaka Ratnayake
Oceanography can be described as an interdisciplinary science, and it emerged as an established academic field only during the last few decades. The discipline entails the study of physical and chemical properties of ocean water and the ocean surface, the wave patterns, biological processes, species...

Oceanography is a science which dates back many centuries where humans undertook sea voyages for the first time. The study of waves and other superficial parameters also dates back to the time of Aristotle. However, it was only a few decades back that oceanography was...

In recent years, scientists have noticed signs of damage in coral reefs. These signs are very widespread-in fact they can be seen almost everywhere in the oceans around planet Earth. Some reefs appear damaged, while others are "bleached"- turned white. This disturbing realization has prompted...

For many, differentiating between Antarctic and Arctic ice is a challenge. Although the two continents can be differentiated by their geographical locations, many do not realize that there are many other differences existing between the two landmasses. For one, polar bears live only in the...
New Jersey teen builds a one-man submarine
By: Christine Zibas
It took the longest of any project undertaken by New Jersey teenager Justin Beckerman, currently a high school junior at West Morris Mendham High School. (His next longest project was a tree house.) Unlike other teenagers who spend their days playing video games or...
A description of the continental shelf
By: Jose Juan Gutierrez
A continental shelf is a portion of a continent that extends far out into the sea shore. It usually extends from the line of a coast to a number of miles into the sea and to a point called the shelf break, where the shelf...
An overview of ocean biogenic sediments
By: Jose Juan Gutierrez
Biogenic sediments are the skeletal remains of either plant or animal marine species. The hard skeletal structures of marine organisms are important constituents of the deep ocean sediment and many layers of the deep ocean floor are almost entirely composed of calcareous and siliceous skeletal...
Facts about marine sediments: Pelagic sediments
By: Jose Juan Gutierrez
Pelagic sediment comprises fine-grained material composed of lithogenous, biogenous, and cosmogenous particles that have been deposited in the ocean floor away from the neritic zone. Pelagic sediment is composed of calcareous and siliceous shells from marine organisms, fine-grained clay material, volcanic ash and trace amounts...
Facts about marine sediments: Biogenous deposits
By: Jose Juan Gutierrez
Biogenic deposits are fine-grained red, brown or light-colored skeletal remains of planktonic organisms that have been deposited on the ocean floor. Biogenic deposits are referred to as oozes. There are two different groups of biogenic oozes; calcareous oozes and siliceous oozes. Biogenic deposits of biogenic...
