Mar Menor
By:Dani,Bruno
1- Indicate location of the Mar Menor
The Mar Menor is located in in the Region of Murcia in southeastern Spain
2- What is eutrophication?
Eutrophication is the process where a body of water becomes overly enriched with nutrients, typically nitrogen and phosphorus
eutrophication
This excessive nutrient buildup triggers rapid algal growth (algal blooms), which blocks sunlight, depletes dissolved oxygen as the algae decompose, and ultimately suffocates aquatic life
3- Explain why it happens and how it appears.
How It Appears
Why it happens
The root cause of eutrophication is an excess of nutrients—specifically nitrogen and phosphorus—entering a water body. This is primarily driven by human activities:
The phenomenon unfolds through a destructive chain reaction within the aquatic ecosystem:
- Algal Bloom
- Sunlight Blockage
- Plant Death
- Decomposition
- Oxygen Depletion
- Dead Zone
- Agricultural Runoff
- Livestock Waste
- Wastewater & Sewage
- Industrial Emissions
4-What are the consequences of this problem for the ecosystem?
The consequences of eutrophication are causing massive wildlife die-offs, toxic water conditions, and the collapse of entire aquatic food webs. When an ecosystem loses its balance due to nutrient pollution, the damage ripples through every level of biological life.
- Massive Loss of Biodiversity
- Disruption of the Food Web
- Release of Dangerous Toxins
- Severe Alteration of Water Quality
5-Find information about the catastrophe and tell how it happened

Measures to avoid contamination of the hydrosphere in the Mar Menor
Measures to avoid contamination of the hydrosphere in the Mar Menor focus on preventing excess nutrients—especially nitrogen and phosphorus—from entering the water body. This requires controlling and reducing nutrient runoff from agricultural areas, wastewater, and stormwater through stricter treatment, buffer zones, and better land-management practices.
