Southern Ocean, potential effects

Potential Effects of Increased Ultraviolet Radiation on the Productivity of the Southern Ocean... 

Central Pacific, Southern Ocean) can be Fe rather than N or P limited (Behrenfeld and Kolber, 1999 Martin et al, 1994). These regions have dissolved inorganic N and P concentrations in excess of phytoplankton requirements, indicating that N enrichment is not likely to impact eutrophication potentials of these waters and that any eutrophication effect of N enrichment is rehant on parallel new Fe inputs (Kolber et al., 2002).
