They took salt water and algae samples for the University Centre of Svalbard.

In most open waters, concentrations fluctuate somewhat around typical levels of about 3.5%, much higher than what the body can tolerate and the most above what the kidney can withstand. One point that is often overlooked in the claim that the kidney can excrete NaCl at Baltic concentrations of 2% (in arguments to the contrary) is that the gut cannot absorb water at such concentrations, so there is no benefit to drinking such water. However, the salinity of the surface waters of the Baltic Sea is never 2%. It is 0.9% or less and therefore never higher than that of body fluids. Drinking seawater temporarily increases the concentration of NaCl in the blood. This signals the kidney to excrete sodium, but the concentration of sodium in seawater is higher than the maximum concentration capacity of the kidney.
Eventually, the concentration of sodium in the blood reaches toxic levels, removes water from the cells and disrupts nerve conduction, ultimately leading to fatal seizures and cardiac arrhythmias. [ref. needed] Saltwater intrusion can be a major environmental problem that can affect the water supply needed for drinking or irrigation. Saltwater intrusions are caused in places close to the ocean where there is excessive abstraction of groundwater supply. This allows groundwater salt to migrate inland, spoiling aquifer quality for most applications. Saltwater intrusions are usually caused by excessive use of groundwater for irrigation in agriculture or to provide drinking water to large cities. City officials, engineers and maintenance workers familiar with the building reported salt water gushing through the foundation, and residents described a garage that was often flooded. Britannica.com: Encyclopedia article on salt water Most ocean-going vessels desalinate drinking water from seawater using processes such as vacuum distillation or multi-stage flash distillation in an evaporator or, more recently, reverse osmosis. These energy-intensive processes were generally not available in the age of sailing. The largest sailing warships with large crews, such as Nelson`s HMS Victory, were equipped with stills in their galleys.  Animals such as fish, whales, sea turtles and seabirds such as penguins and albatrosses have adapted to life in a very salty habitat.
For example, sea turtles and saltwater crocodiles remove excess salt from their bodies through their tear ducts.  Salt water most commonly refers to ocean waters where the total concentration of ionic solutes is typically about 35 grams per litre (also expressed as 3.5%, or 35 parts per thousand). Due to these high dissolved ion concentrations, the density of salt water (1.028 g/L at 4°C) is slightly higher than that of fresh water (1.00 g/L). As a result, freshwater floats above salt water in poorly mixed situations where the two species meet, such as estuaries and some underground reservoirs. Yamaha Seascooter Note that this one is specifically designed for use in salt water and has less buoyancy in fresh water, so it`s not the right choice if you plan to use it in the pool. While saltwater pools still require cleaning chemicals, they don`t consume as much. Above-ground and groundwater saltwater is sometimes “exploited” for its content of economically useful minerals. It is located on Point Judith Pond, one of the most spectacular saltwater ponds in the state.
“Salt water.” Merriam-Webster.com Dictionary, Merriam-Webster, www.merriam-webster.com/dictionary/saltwater. Retrieved 12 October 2022. Groundwater can also be extremely salty. Groundwater salt water is commonly found in oil and gas well fields, especially after hydrocarbon resources have been depleted by mining. Research conducted by the Scripps Institution of Oceanography in 1957 studied water in pelagic and neritic locations in the Pacific Ocean. Direct microscopic counts and cultures were used, with direct counts in some cases up to 10,000 times higher than those of cultures. These differences were attributed to the appearance of bacteria in the aggregates, the selective effects of culture media, and the presence of inactive cells.
