Seawater tends to maintain consistency in terms of salinity, pH, composition, etc., but this consistency is only achieved offshore, where conditions are always the same. The moment we capture water near the coast, tributaries, rivers, ports or near some place where there is a human influence, these parameters are modified in a large way.
To begin with, the PH will be seriously modified, losing one of the greatest attributes of seawater, alkalinity. They have found a pH variability of more than 20%.
Another parameter that varies is salinity, which could vary up to 30%, modifying another of the attributes of seawater, which is the contribution of mineral salts.
But without a doubt, the most notable difference is the ionic bio-availability of minerals and trace elements, necessary for our body to assimilate them in an optimal way.
The minerals that reach the sea through the erosion of the coast, rivers, etc., are inorganic and not bio-available. For the mineral to be assimilable, a process called "marine biocenosis" is needed, where the plankton pre-digests this inorganic mineral and transforms it into bioactive and bioavailable, that is, completely assimilable by the human body.
Plankton are found in the high seas at a certain depth, from about 15 m, and travel through it by ocean currents. There are certain places where these currents converge creating a whirlpool called "vortex" and amalgamating a large amount of plankton. It is in this place where a bag of seawater is created, marine plasma, rich in bioavailable minerals, very similar in their chemical composition to our internal environment.
These are the reasons why seawater is captured on the high seas, to obtain the highest quality and ionic bio-availability.
