The Principle Of Constant Proportions
What is the Forchhammer'due south Principle?
Forchhammer's Principle refers to the chemic composition of ocean water.
A CTD (conductivity, temperature, and depth) device. The primary function of this tool is to detect how the conductivity and temperature of the h2o column changes relative to depth. Electrical conductivity is a measure of how well a solution conducts electricity. Conductivity is directly related to salinity, which is the concentration of salt and other inorganic compounds in seawater. Salinity is one of the nearly bones measurements used by sea scientists. When combined with temperature data, salinity measurements can be used to determine seawater density, which is a primary driving strength for major bounding main currents.
In 1865, the Danish geologist and mineralogist Johan Georg Forchhammer, with the assist of naval and civilian collaborators, collected numerous samples of seawater from the Northern Atlantic and the Arctic Sea. He wanted to determine why the salinity (or "saltiness") of seawater varies in dissimilar areas of the sea.
Forchhammer put the samples through a detailed serial of chemical analyses and found that the proportions of the major salts in seawater stay virtually the aforementioned everywhere. This constant ratio is known every bit Forchhammer'south Principle, or the Principle of Constant Proportions. In addition to this principle, Forchhammer is credited with defining the term salinity to mean the concentration of major salts in seawater.
Forchhammer's discovery helped scientists empathize that salinity levels in seawater vary due to the addition or removal of fresh h2o, rather than differing amounts of salt minerals in the h2o. The principle is still practical today in marine enquiry, and provides a elementary fashion to estimate salinity and trace the mixing of water masses in the global ocean.
