Ocean water almost exclusively moves around the rest of the water cycle from being evaporated into clouds and precipitated into other storage areas. If the base temp and salt content of the water is lower then it will take more energy from the sun to make the water evaporate. This will make it so that less water will be in the air.
Water only reaches glaciers through condensation/precipitation then freezing. If there is less water in the air then less water will precipitate onto and freeze to glaciers.
Going back to animals the urine infiltrates the soil. This makes more water going to soil from animals but less from precipitation. When the water from animals is put into the soil it can be evaporated, flow into ground water (groundwater flow) or runoff in rivers (surface runoff). Plants and transpiration are not directly affected. If the water not is not already cleaned it will be cleaned as it percolates through the ground water,
According to https://water.usgs.gov/edu/drinkseawater. the parameters for fresh water are -Fresh water < 1000 ppm -Slightly saline water - From 1,000 ppm to 3,000 ppm -Moderately saline water - From 3,000 ppm to 10,000 ppm -Highly saline (Ocean) water - From 10,000 ppm to 35,000 ppm If we are going from 35, 000 ppm of salt to less than 1000 ppm of salt then where is the excess salt going. This goes back to earlier when I said the salt was returned to the ocean and we are going to explore what the extra salt content will be doing to the animals and plants.
Millions of years of evolution have allowed fish to live and breath in the salty waters. If there is a heightened salt content the fishes gills could become blocked or they could "drown" in the super salty water. Same goes for water plants that have grown used to the salinity. Too much could kill them.
