Farmers have teamed up with scientists to find new ways to produce more food, improve the quality of their farmland and earn more money.
The mixing of deep waters upward with surface waters—in a phenomenon known as upwelling—is latitude dependent and occurs predominantly in the equatorial region.
Coastline shape, local climate and wind, trade winds, and ocean bottom topography also affect upwelling. Mangerud, global variation in marine radiocarbon reservoir effect evident in shell carbonates are due to the incomplete mixing of upwelling water of “old” inorganic carbonates from the deep ocean where long residence times of more than 1,000 years cause depletion of carbon 14 activity through radioactive decay, resulting in very old apparent carbon 14 age.
Fighting Climate Change, Doubling Incomes: Rice Variety Developed with Nuclear Techniques Expands in Indonesia.
Stocky, strong and quick to ripen – that is how Indonesian farmers like their rice, and that is exactly what nuclear science has delivered to them.
Carbon 14 is a naturally occurring isotope of the element carbon and is called radiocarbon because it is unstable and weakly radioactive.
Another characteristic of carbon 14 is that it is continually being formed in the upper atmosphere as a product of the reaction between neutrons produced by cosmic rays and nitrogen atoms.
Studies show that equilibration of carbon dioxide (with carbon 14) in surface water is of the order of 10 years.
The degree of equilibration of carbon dioxide in deep water remains unknown.
These carbon 14 atoms then instantaneously react with oxygen present in the atmosphere to form carbon dioxide.
The carbon dioxide formed with carbon 14 is indistinguishable from the carbon dioxide with the other carbon isotopes; hence the pathway of carbon 14 into the ocean, plants, and other living organisms is the same as that of carbon 12 and carbon 13.
Marine organisms and those who consume them take in carbon 14 from the exchange process of carbon 14 (in the form of carbon dioxide) in the atmosphere and the ocean or any body of water.
