The ecosystem is an ecological system consisting of all of its biotic and abiotic factors
Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.
Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.
Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.
Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.
Hope this helps!
