How does the ocean's salinity vary with depth?
What will be an ideal response?
There is a rapid change in salinity between the depths of about 300 meters (980 feet) and 1000 meters (3300 feet). For the low-latitudes, the change is a decrease in salinity, because surface water salinity is high due to evaporation and little to no precipitation and runoff. For the high-latitudes, the change is an increase in salinity because surface water salinity is low due to abundant precipitation and runoff and the melting of freshwater icebergs. In addition, cool temperatures limit the amount of evaporation that takes place.
