How much deuterium is in the ocean?
Deuterium has a natural abundance in Earth’s oceans of about one atom in 6420 of hydrogen. Thus deuterium accounts for approximately 0.0156% (0.0312% by mass) of all the naturally occurring hydrogen in the oceans, while protium accounts for more than 99.98%.
What is the mass of water in the ocean?
The density of ocean water is approximately 1000 kilogram per cubic meter….Mass of the Oceans.

How much deuterium is in a liter of water?
It is water with reduced deuterium content. Deuterium is a “bad” isotope form of hydrogen, found in any naturally accrued water. On average every natural water has 150 parts per million of deuterium per litre, so every 1 hydrogen atom out of 6000 is deuterium.
What is the mass of deuterium?
2.014 amu
The atomic number of deuterium is 1 and the mass number is 2. The atomic mass can be given as 2.014 amu. This is also a stable isotope of hydrogen but is less abundant.
What are the 5 distinct water masses of the ocean?
We talk about “the global ocean circulation” because although the Earth officially has five oceans, they are not totally separate bodies of water. In fact, the Arctic, Atlantic, Indian, Pacific and Southern oceans are interconnected, with water circulating and moving between them.
What is the densest water mass in the ocean?
Antarctic bottom water
Antarctic bottom water (AABW) is the densest global-scale water mass. It is produced around Antarctica, sinks along the Antarctic continental slope and spreads northward to fill most of the ocean deeper than 4 km (Orsi et al., 1999).
What is deuterium in our water?
Deuterium is a “bad” isotope form of hydrogen, found in any naturally accrued water. On average every natural water has 150 parts per million of deuterium per litre, so every 1 hydrogen atom out of 6000 is deuterium. Deuterium Depleted Water is very low in deuterium (25 – 125 ppm).
How many atoms of deuterium are in water?
two
Water is composed of two hydrogen atoms and an oxygen atom. Heavy water, also called deuterium oxide, is composed of two deuterium atoms and an oxygen atom.
How do you find the mass of deuterium?
For deuterium oxide, 2H2O , D2O , simply add up the molar masses of each element: (2×2.014+15.999)⋅g⋅mol−1 ≅ 20.0⋅g⋅mol−1 .
What are considered the characteristics of a water mass in the ocean?
An oceanographic water mass is an identifiable body of water with a common formation history which has physical properties distinct from surrounding water. Properties include temperature, salinity, chemical – isotopic ratios, and other physical quantities which are conservative flow tracers.
What is the saltiest water mass in the world’s oceans?
Atlantic
That the Atlantic is the saltiest of the oceans is very clear with a branch to high salinity values at higher temperatures. The most voluminous water mass is the Pacific Deep Water that fills most of the Pacific below the intermediate waters at about 1000 m.
