2022-03-01 07:35:24 Mitigation of Eutrophication

Treating Industrial effluents domestic sewage to remove nutrient-rich sludge through wastewater processing.

Riparian buffer: Interfaces between a flowing body of water and land created near the waterways, farms, roads, etc. in an attempt to filter pollution.

Sediments and nutrients are deposited in the buffer zones instead of deposition in water (Wetlands, estuaries are natural riparian buffers).

Increase in efficiency of nitrogen & phosphorous fertilisers and using them inadequate levels.

Nitrogen testing & modelling: N-Testing is a technique to find the optimum amount of fertiliser required for crop plants. It will reduce the amount of nitrogen lost to the surrounding area.

Encouraging organic farming.

Reduction in nitrogen emission from vehicles and power plants. Open / Comment

2022-02-28 17:31:11 Dead zones

Dead zones (biological deserts) are increasing in the coastal delta and estuarine regions.

Hypoxic zones (zones deprived of oxygen) can occur naturally (due to upwelling of nutrients).

They can be created or enhanced by human activity to form dead zones.

Dead zones are areas in the ocean with very low oxygen concentration (hypoxic conditions).

Dead zones emerge when influx of chemical nutrients spur algae growth.

These zones usually occur 200-800 meters (in the saltwater layer) below the surface.

Dead zones are detrimental to animal life. Most of the animal life either dies or migrates from the zone.

One of the largest dead zones forms in the Gulf of Mexico every spring (farmers fertilize their crops and rain washes fertilizer off the land and into streams and rivers).

There’s a dead zone in Gulf of Oman and it’s growing. Open / Comment

2022-02-28 15:35:16 Harmful Algal Blooms

Most algal blooms are not harmful, but some produce toxins. These are known as Harmful Algal Blooms (HABs).

Toxicity: Some algal blooms when died or eaten, release neuro & hepatotoxins which can kill aquatic organism & pose a threat to humans. E.g. Shellfish poisoning.

HAB events adversely affect commercial and recreational fishing, tourism, and valued habitats, creating a significant impact on local economies and the livelihood of coastal residents. Open / Comment

2022-02-27 10:57:24 Oil Spills

The most common cause of oil spill is leakage during marine transport and leakage from underground storage tanks.

An oil spill could occur during offshore oil production as well.

Impact of oil spill on marine life

Oil being lighter than water covers the water surface as a thin film cutting off oxygen to floating plants and other producers.

Within hours of an oil spill, the fishes, shellfish, plankton die due to suffocation and metabolic disorders.

Birds and sea mammals that consume dead fishes and plankton die due to poisoning Open / Comment

2022-02-26 18:28:50 Artificial Cloud seeding

Cloud seeding is the process of spreading either dry ice or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain.

Since most rainfall starts through the growth of ice crystals from super-cooled cloud droplets in the upper parts of clouds, the silver iodide particles are meant to encourage the growth of new ice particles Open / Comment
