NOAA’s latest forecast predicts the size of the hypoxic zone, commonly known as the “dead zone,” in the Gulf of Mexico for summer 2024.
Forecast Details
NOAA projects the dead zone to cover approximately 5,780 square miles during peak summer months.
Factors Influencing Dead Zone
The size of the dead zone fluctuates annually due to weather patterns, river discharge rates, and ocean currents.
Causes of Dead Zone
Excess nutrients like nitrogen and phosphorus from agricultural activities in the Midwest are primary contributors.
Impact on Marine Life
Low oxygen levels in the dead zone make survival difficult for marine organisms.
NOAA’s Monitoring and Mitigation Efforts
NOAA emphasizes ongoing monitoring and mitigation efforts to address the Gulf’s hypoxic zone.
Environmental Advocacy and Regulations
Environmental groups advocate for improved agricultural practices and stricter regulations to reduce nutrient runoff.
Conclusion
Continued research and conservation efforts are crucial to mitigate the size and impact of the dead zone.
