Salinities less than 5ppt in the lower 40 miles of the Potomac River killed 50% of the marketable oysters after Agnes, and blocked reproduction that year. Because saltier water is heavier, the oysters near the surface suffered low-salinity water for a longer period of time.alinities less than 5ppt in the lower 40 miles of the Potomac River killed 50% of the marketable oysters after Agnes, and blocked reproduction that year.

Water has great abundance on the Earth, and of that abundance about 97% is sea water. Sea water contains about 3.5% by weight of salt (sodium chloride).The salinity does vary, and the combination of salinity and temperature has a major influence on ocean currents and behavior.eawater of average salinity 35 ppt freezes at -1.94Â°C (28.5Â°F). The salinity of the water is measured with a CTD instrument (Conductivity, Temperature, Depth).
