A stye is an infection of an oil gland in the eyelid. It produces a red, swollen, painful lump on the edge or inside surface of the eyelid. Styes usually occur closer to the surface of the eyelid than do chalazia.
The most abundant salts in the ocean are chlorine, sodium, magnesium, sulfur, calcium, and potassium. Ocean salinity is affected by multiple factors including ice melt, inflow of river water, evaporation, precipitation, wind, wave motion, and ocean currents.
It has roughly 2/3 the salt content of regular seawater. Ocean salinity (expressed in  - per mil) is approximately equal to the weight, in grams, of salts dissolved in 1000g of seawater. This would be the salt concentration in parts-per-thousand (). Average ocean water has a salinity of 35g of dissolved salts.
