Oceanography, also called marine science, is the study of oceans. It includes the study of physical oceanography, marine chemistry, marine geology, and marine biology. Areas covered in oceanography are the shape, depth, and distribution of oceans, and also their composition, life forms, ecology, and water currents, as well as their legal status. If you would like to know more or share your knowledge about oceanography, ask and answer questions here! Includes questions related to the study of Earth's oceans and seas.
The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just…

Most of the salt in the oceans came from land. Over millions of years, rain, rivers, and streams have washed over rocks containing the compound sodium chloride (NaCl), and carried it into the sea. You may know sodium chloride by its common name: table salt! Some of the salt in the oceans comes from …

The ocean water is cycled through the Earth's crust, changing its mineral composition in the process. The water goes down through cracks in the Earth's crust until it hits very hot rock. It becomes superheated and dissolves minerals from the rocks, then shoots up through the hydrothermal vents back …

It doesn't The temperature and salinity of seawater determine its density. Water gets denser as it gets saltier and reaches a maximum density at 4 °C. Salinity does affect the boiling point and freezing point of water, but not its temperature.

All light penetrates water to a certain extent. However, the shorter the wavelength of the light, the more energy it carries and the less it is absorbed by the water. Blue has a short wavelength compared to red light, so it penetrates further than most of the rest of the visible spectrum.
