What is Salinity?
Salinity is a measure of how much salt is in the water.
Salinity is usually measured in parts per thousand (ppt) units. Parts per thousand is how many grams of salt are dissolved per liter of water.
Why is Salinity Important?
All plants, animals, bacteria, and algae need a certain salinity range in order to survive. Changes in salinity can kill an organism.
The salinity in the Neuse River and Pamlico Sound can range from 0ppt to 35ppt.
