What contributes to the high biological activity and surface nutrients in southern polar waters?
A) Deep-water upwelling
B) Weak stratification
C) There is a lack of continental margins
D) All are contributing factors

Question

Quizplus · Accepted Answer

There are a few factors that culminate in southern polar waters to produce a high biologically active area. There is an absence of continental margin which allows the Antarctic Circumpolar Current to minimize salinity differences. Turbulence and weak stratification encourages deep-water upwelling events. Information can be found in the section The Ocean Is Stratified by Density.
