Summary
The Mauritanian benthic fauna faces periodical, severe hypoxic and anoxic conditions caused mainly by dry climatic conditions. Hypoxic episodes have dramatically increased under the arid and dry climates of the 1970s, 1980s and 1990s. Strong northeast trade winds bring the settled nutrients from the deep ocean water to the surface, giving rise to phytoplankton blooms.
The rapid intensification of Mauritanian agriculture may indirectly increase hypoxia through fertilizer usage. Point and non-point source pollution into Mauritanian's coastal waters should be managed to protect the benthic biodiversity.
