When something is low in salinity it means that the salt level is low. This is often a term used in reference to salt water.
What causes low salinity in the oceans at high latitudes?In subtropical latitudes, high surface evaporation creates high salinity near the sea surface. In subpolar latitudes, high precipitation creates low salinity near the sea surface. As these waters flow into the ocean interior, they create layers of high and low salinity.
Salinity falls as the out flowing tide brings in more fresh river water.
The salinity of a river can vary depending on factors such as the source of water, climate, and human activities. Typically, freshwater rivers have low salinity levels, ranging from 0.1 to 0.5 parts per thousand (ppt). If a river is influenced by seawater intrusion or human activities like mining or agriculture, its salinity can be higher.
Higher levels of salinity produce brine shrimp that are smaller, but reach sexual maturity faster than those in lower levels. Also lower levels of salinity tend to allow more predators into the ecosystem.
Fresh water is characterized by low salinity levels, typically less than 0.5 parts per thousand. It is essential for sustaining life and is found in lakes, rivers, groundwater, and glaciers. Fresh water is a vital resource for drinking, agriculture, and various industrial activities.
Cold water with high salinity
Salinity in the ocean is highest in regions where evaporation is high and precipitation is low. Density in seawater is determined by both temperature and salinity.
Cold water with high salinity takes up more volume than warm water than low salinity

What causes low salinity in the oceans at high latitudes?In subtropical latitudes, high surface evaporation creates high salinity near the sea surface. In subpolar latitudes, high precipitation creates low salinity near the sea surface. As these waters flow into the ocean interior, they create layers of high and low salinity.
What happens is, the high salinity water (hyper tonic solution), mixes with the low salinity water (Hypo tonic solution), and eventually the sodium and chloride ions will slowly move into the lower salt water, and create a uniformly salty water.
Salinity falls as the out flowing tide brings in more fresh river water.
Tropical rainforests typically have low salinity levels in both the soil and water due to the frequent rainfall that helps to wash away salts. The constant moist conditions in rainforests also prevent salt buildup in the soil, keeping salinity low. However, the salinity of a rainforest can vary depending on factors such as proximity to the ocean or human activities like agriculture.
The freshwater biome has a salinity of 0.05 percent or less, making it a low-salinity environment that is home to various species of plants and animals adapted to living in such conditions.
