👉 Subsalinity is a term used in hydrology and water quality to describe the concentration of dissolved salts (sodium chloride, potassium chloride, magnesium chloride) in seawater. It is typically measured using a solubility test or by analyzing the pH of seawater samples. Subsalinity can be beneficial for aquatic ecosystems as it helps maintain salinities that are beneficial for marine life and supports the growth of certain species. However, excessive subsalinity can have negative impacts on water quality,
