Oceanography

Oceanography is that the study of the physical, chemical, and biological features of the ocean, including the ocean’s ancient history, its current condition, and its future. In a time when the ocean is threatened by climate change and pollution, coastlines are eroding, and entire species of marine life are at risk of extinction, the role of oceanographers may be more important now than it has ever been. Indeed, one of the most critical branches of oceanography today is known as biological oceanography. It is the study of the ocean’s plants and animals and their interactions with the marine environment. But oceanography is not just about study and research. It is also about using that information to help leaders make smart choices about policies that affect ocean health. Lessons learned through oceanography affect the ways humans use the ocean for transportation, food, energy, water, and far more. Oceanography, science concerned with all aspects of the world’s oceans and seas, including their physical and chemical properties, their origin and geologic framework, and therefore the life forms that inhabit the marine environment. A brief treatment of oceanography follows. For whole shebang , see hydrologic sciences: Study of the oceans and seas. Traditionally, oceanography has been divided into four separate but related branches: physical oceanography, chemical oceanography, marine geology, and marine ecology. Physical oceanography deals with the properties of seawater (temperature, density, pressure, then on), its movement (waves, currents, and tides), and therefore the refore the interactions between the ocean waters and the atmosphere.
