The proposal for the name Southern Ocean won 18 votes, beating the alternative Antarctic Ocean. Half of the votes supported a definition of the ocean's northern limit at 60°S (with no land interruptions at this latitude), with the other 14 votes cast for other definitions, mostly 50°S, but a few for as far north as 35°S.
The ocean is the body of salt water that covers approximately 70.8% of Earth. [8] In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. [9] The following names describe five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic.
Deep seawater has a temperature between −2 °C (28 °F) and 5 °C (41 °F) in all parts of the globe. [30] Seawater with a typical salinity of 35 ‰ [31] has a freezing point of about −1.8 °C (28.8 °F). [32] When its temperature becomes low enough, ice crystals form on the surface.
The total dissolved solids (TDS) of the ocean are between 33 and 36.5 gl −1. The TDS of standard seawater at 25 o C is 36gl −1. TDS of seawater would be lower near the coast as there is fresh water supply through a river. The charge in TDS of seawater can indicate the existence of groundwater supply, submarine spring and the transition zone ...
Seawater, or sea water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium ( Na +
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
The dependence on pressure is not significant, since seawater is almost perfectly incompressible. [3] A change in the temperature of the water impacts on the distance between water parcels directly. [clarification needed] When the temperature of the water increases, the distance between water parcels will increase and hence the density will ...
Why this theory is so significant is the interaction between the tectonic plates explains many geological formations. [8] In regards to marine geology, the movement of the plates explains seafloor spreading and mid-ocean ridge systems, subduction zones and trenches, volcanism and hydrothermal vents, and more.
