Oceanography


Introduction:

Oceanography, also called oceanology or marine science, is a huge technology regarded a branch of the Earth sciences. Oceanography is an interdisciplinary technology that uses ideas from biology, chemistry, geology, meteorology, and science to evaluate ocean currents, sea environments, ocean stormy weather, surf, ocean plate tectonics, and features of the sea ground, such as unique biomes such as cold penetrates and hydrothermal ports. Modern oceanography started in the 1760s.

What do Oceanographers do?

Seismology and sub-seabed geophysics are being researched using marine observatories. Moorings, with steel or Kevlar wire increasing from near the ocean surface to its base, are laced with equipment that record findings internal, and perhaps communicate them to a satellite television. And, increasingly, autonomous undersea vehicles (AUVs) drive themselves or move with voltages for years at a time.

In the environmentally sensitive coastal ocean and estuaries, "cat-scans" can be done using fast, small boats towing equipment that fly through the water on a carefully managed course. Meanwhile, acoustic waves are sent down through the water line, and their reflections off small contaminants in the water give complete information of the sea speed, from top to bottom.


Oceanographic Technology Uses:

• Deep-sea cameras may be found on Remotely Operated Vehicles (ROVs) operated from delivers, on landers placed onto the seafloor for a long period, or on robot submarines. ROVs are extremely mobile and allow us to discover areas of the ocean where the landscape stops us from using other study and sampling methods - such as submarine canyons.

• Sonar can offer fascinating visual 'pictures' of sound shown from animal life in the sea. They can offer understanding into animal behavior, such as the daily migration from deep to superficial absolute depths.

• Long-range sonar has many uses in relationship with ocean sources, from applying the form to identifying the structure of the seabed. Low regularity sonar can also go through the seabed, and offer details from structures beneath.
