merisuolapitoisuus
Merisuolapitoisuus, or salinity, refers to the concentration of dissolved salts in seawater. It is typically measured in parts per thousand (ppt) or practical salinity units (psu). The average salinity of the world's oceans is about 35 ppt, meaning that for every kilogram of seawater, there are approximately 35 grams of dissolved salts.
The primary components of sea salt are sodium chloride (NaCl), but other ions such as sulfate, magnesium,
Salinity plays a crucial role in oceanographic processes. It affects seawater density, which in turn drives
