Runoff
Big rain events Nutrient runoff into rivers
Algae Bloom Excess Nutrient Cycling
Algae grows and blocks sunlight Seagrasses die and stop producing oxygen Fish Suffocate and die
Hypoxic Zone (Low Oxygen)
Effects
Skin rashes/illness Fish health and deaths and fishing bans Shellfish toxicity Seagrass smothering Waterway system Water pollution Boating restrictions And more...
Outflow
Decomposers multiply and consume more oxygen Phosphorus and Nitrogen released to surface Algal mat grows larger & thicker
