Marine organisms cope with high salinity through various adaptations. Many have developed specialized cells or glands to excrete excess salt, while others, like some fish, actively regulate their internal osmotic balance by absorbing water and excreting concentrated salt solutions. Some organisms, such as certain species of jellyfish and sea turtles, can tolerate high salinity levels by adjusting their cellular processes to maintain homeostasis. Additionally, many marine organisms have evolved mechanisms to avoid dehydration, such as creating protective barriers or utilizing osmoprotectants.
If salinity increased at the poles, the water near the poles would become denser. This increased density could impact ocean circulation patterns and potentially affect marine life that depend on specific salinity levels. Additionally, it could lead to changes in ice formations and melting rates in polar regions.
A river flowing into the sea is causing the decrease in salinity
Whatever the organism is it will die a dreadfully painfull death.
Salinity is increased.
Cold water with high salinity takes up more volume than warm water than low salinity
probably not, marine fish are designed to osmoregulate at a very specific and unchanging salinity (usually a SG of 1.025) whereas brackish fish by nature are adaptable to anything from fresh water to fully marine but are usually situated around a SG of 1.008. odds are if you put a marine fish in brackish water it would die
Water salinity describes the amount of salty minerals dissolved in a sample of water. It would therefore make no difference whether the water is warm or cold, since you would have the same amount of salt dissolved in the water per cm3 of water. Salinity would change if you added more water, or if the water was so hot that some of it evaporates, leaving all the dissolved solids behind, but decreasing the amount of water it is dissolved in.
Estuaries would be a likely environment for marine organisms well adapted to drastic changes in salinity, as estuaries experience fluctuations in salinity levels due to the mixing of freshwater from rivers and saltwater from the ocean. Organisms in estuarine environments have developed physiological mechanisms to tolerate these changes.
The typical salinity level in a saltwater aquarium is around 1.025, which means there is about 35 grams of salt per liter of water. This salinity level is crucial for the health of marine organisms as it helps maintain the proper balance of ions within their bodies. It's important to regularly test and adjust the salinity level to ensure the well-being of the aquarium inhabitants.
One pound of salt for every one gallon of fresh water. Also, as the water evaporates, add only fresh water...and slowly! When I kept fish, I would drain half of the remaining water, then mix in the fresh water, then put the mixture back into the tank. This prevents the fish from getting a fresh water shock. The water will evaporate and leave the salt behind, so if you add more salt, it will be too much.
Salinity would decrease in an estuary during spring floods due to the influx of freshwater from increased runoff and precipitation. The dilution effect of the additional freshwater entering the estuary would lower the overall salinity levels.
decrease in density and become water vapor
