Projects on hypoxia (in all programs)

Eutrophication—the over-enrichment of water by nutrients such as nitrogen and phosphorus—is a leading threat to water quality around the world. Also known as “nutrient pollution,” eutrophication upsets the natural balance of aquatic ecosystems, which can lead to algal blooms, red tides, hypoxic or “dead” zones, fish kills, and, eventually, ecosystem collapse.
