UPSC GS 1
Dead Zone
- News:ย The National Oceanic and Atmospheric Administration has forecasted an above-average summer โdead zoneโ in the Gulf of Mexico covering approximately 5,827 square miles.
- Dead Zone or Hypoxia: Refers to low-oxygen areas in the worldโs lakes and oceans.
- Impact on Organisms: Few organisms can survive in hypoxic conditions, hence the name “dead zones”.
- Causes of Dead Zones:ย
-
- Natural Occurrence: Hypoxic zones can occur naturally.
- Human Activities: Human activities can lead to the creation of new dead zones or enhance existing ones.
-
- Formation of Dead Zones:ย
-
- Eutrophication Process: Dead zones occur due to eutrophication, which happens when a body of water is inundated with too many nutrients, such as phosphorus and nitrogen.
- Cyanobacteria Role: Normally, cyanobacteria (blue-green algae) feed on these nutrients. Excess nutrients cause an overgrowth of algae, known as algae blooms.
- Decomposition and Oxygen Depletion:ย When the algae die, they sink to the bottom.
- Bacterial Decomposition: Bacteria decompose the dead algae, stripping dissolved oxygen from the surrounding water.
-
- Location: Dead zones are often near inhabited coastlines.
- Factors Influencing Dead Zones:ย
-
- Wind Influence: Wind can mix oxygen from the surface into deeper water, helping to break up dead zones.
- Hot Temperatures: Can worsen dead zones by warming surface water, preventing oxygen mixing with colder, denser water below.
- Heavy Rainfall: Increases the amount of pollution washed into waterways.
- Shallow Waters: Less likely to stratify and develop hypoxic conditions due to mixing by winds and tides.
- Primary Producers: Shallow, clear waters support phytoplankton, algae, and seagrasses that release oxygen during photosynthesis.ย
-
- Impact on Aquatic Life:ย
-
- Blockage of Sunlight: Dense algal blooms block sunlight, preventing underwater grasses from growing.
- Food and Shelter: Animals depending on these grasses for food and shelter suffer.
-
- Human Contributions:ย ย
-
- Pollution: Human activities cause excess nutrients to be washed into the ocean.
-

-
- Climate Implications:
-
- Third Pole Status: Its extensive ice and snow cover have significant impacts on global climate patterns.
-
- Vegetation:
-
- Inner Valleys: The inner valleys of the Hindu Kush see little rain and have desert vegetation.
-
- Regional Divisions:ย Sections of HKH:
-
- Eastern Hindu Kush: One of the three main sections.
- Central Hindu Kush: Another main section.
- Western Hindu Kush (Bฤbฤ Mountains): The third main section.
