Oceanography

introduction

Oceanography the English word comes from Greek words ὠκεανός meaning "ocean" and γράφω  also known to us  as oceanology and marine science, Oceanography is the branch of Earth Science that studies the ocean and its environments . It covers a extensive range of topics, including marine oeganisms and Ecosystem  dynamics  currents of ocean and  many more and the geology of the sea ground  and  various chemical existences  and physical properties  within the ocean and       across oceans territory . These diverse topics reflect multiple disciplines that oceanographers combine to added knowledge of the world of ocean  and considerate of processes within  oter brancher of science  and  the subject placeoceanography studies the history of the oceans in the geologic past time 

 

History behind Oceanography

Humans first attain knowledge about the  the waves and currents of the ocean and sea in primitive times. Observations  depend on tides of ocean were recorded by Aristotle and Strabo. Early searching of the oceans was primarily for havoc and mainly limited to thesurfaces of ocean  and of the natural world that fishermen brought up in nets, though depth covering by lead line were taken.

Modern improvement of oceanography….

Despite all this, human attain  knowledge about the oceans remained cramped to the topmost few fathoms of the water and a small amount of the foundation mainly in shallow area. Almost nothing was known of the ocean rock bottom The Royal Navy 's attempt to chart all of the world's costline in the mid-19th century toughened the vague idea that most of the ocean was very deep, even though little more was known. As exploration ignited both popular and scientific interest in the polar area and Africa, so too did the mysteries of the unexplored information about  oceans .

The Current of ocean

Since the beginning  ocean trips in oceanography, a major interest was the revise of the ocean currents and temperature measurements. The tides, the Coriolis effect, changes in route and strength of wind, salinity and warmth are the main factors formative ocean currents.
