Saline water
* Drag the correct answer into all target fields
Scientists have long stated that the main effect of global wanning is the melting of the polar ice caps, resulting in a rise in sea levels. However, as we the theory become a reality, it is becoming apparent that this phenomenon also has multifarious secondary effects. Fresh water from ice caps flows into the sea reducing the concentration of salt in the water and thus the sea's density. Saline-dense water would normally sink to the sea bed and then travel to warmer equatorial regions. Concurrently, the warmer, less saline water in warmer parts of the world would travel along the sea surface to the poles, where its salinity would increase and the water would sink. However, as the salinity of polar water decreases, this ocean process slows down. This cycle is vital, however, as it has an oxygenating on the water and also carries nutrients from deeper water to the surface. Therefore, any slowing down of the cycle may have dramatic consequences for sea life.
