A Global Perspective On The Effects Of Eutrophication And Hypoxia On Aquatic Biota And Water Quality, Robert J. Diaz, Janet Nestlerode, Minnie L. Diaz

VIMS Books and Book Chapters

Development associated with human populations has led to the globalization of many environmental problems. In marine systems, the most serious of these problems are directly related to the process of eutrophication. The increased production of organic matter in these marine systems associated with eutrophication is the primary factor impacting species abundance and composition and dissolved oxygen budgets. Oxygen, which is essential to maintaining balance in ecosystem processes through its role in mediating microbial and metazoan activities, has declined to critically low levels in many systems, which has led to the development of hypoxia (/l) and anoxia (0 ml O2/l). Currently, …
