如果我們分析海水的鹽度,會發(fā)現(xiàn)地區(qū)間只有輕微的變化,然而有些小的變化是重要的。 導致海洋的鹽度變化的基本過程有三個。
其中之一是通過蒸發(fā)的方式即把液態(tài)水轉化為水蒸氣來減少海洋中的水分。這樣由于鹽留了下來,所以鹽度增大。
當然,如果這種方式走向極端,將會余下白色的鹽晶體。 與蒸發(fā)相反的是降水,如降雨,由此水被加入海中,海水被稀釋,從而鹽度降低。 這種情形會發(fā)生在大量降雨的地區(qū),或江河入海岸處。 因此,鹽度通過蒸發(fā)減少水分而上升或通過降水或徑流增加淡水成分而下降。
一般來說,在陽光很強烈的熱帶地區(qū),海水的鹽度略高于世界上其它沒有熱帶那樣多的'蒸發(fā)的地區(qū)。 同理,在江河稀釋海水的海岸地帶,海水鹽度略低于其它海區(qū)。
第三個可以變更鹽度的過程與海洋中冰的形成和融化有關。 海水凍結時,溶于其中的物質被留了下來。 這樣,在新形成的海水冰面的正下方的海水比在冰形成之前有更高的鹽度。 當然,當冰融化的時候,會降低周圍水中的鹽度。 在南極洲邊緣的威德爾海中,結冰過程增加低溫海水的鹽度,從而形成了濃度最大的海水。 這些大密度的海水下沉,可以在世界海洋的深水域發(fā)現(xiàn)。
