Oxygen depletion.Seawater is full of dissolved oxygen, however decomposing sewage and other biomatter in oceans can result in a condition known as ‘hypoxia’ or oxygen depletion. TYPES OF MARINE POLLUTION: FACTS AND STATISTICS What causes ocean pollution? However, human activities often introduce unnecessary noise in the marine ecosystem which is detrimental to life in the area. With reference to my last post, where i talked about how plastic was the most common foreign element found in the ocean, plastic waste is a pertinent form of physical pollution to the ocean environment. Airplanes or any loud sounds cause noise/sound pollution. However, today I’m going to talk about marine pollution only. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). In order to prevent them, we have to do many things. Nutrient pollution mainly refers to the pollution of hazardous chemicals leading to the various health and environmental problems. All this plastic waste can pose a serious threat to the survival of marine fauna who can die by ingestion, entanglement, and suffocation. Noise pollution. Pollution does not only damage or kill the biotic components of the waters, but it can also endanger health or even threaten the lives of humans who use polluted biota or waters.

According to NOAA the largest source of ocean pollution is nonpoint source pollution – essentially runoff, or waste flowing from land into the sea. There are several types of marine pollution, each of which has the potential to harm the delicate balance of life. Marine pollution causes due to sewage disposed of in sea water. Chemical pollution refers to the introduction of chemicals into the ocean environment. Plastic fishing nets are known to kill thousands of dolphins, turtles, seabirds, sharks, etc., in the oceans every year. This makes it hard for oxygen loving marine life – plants, fish and animals – to survive in the oceans.2. Not only can they affect fish and other marine life, when pollutants get into the water, they have a devastating effect on the water cycle. According to NOAA (National Oceanic and Atmospheric Administration), there are 4 major sources of oil spill enhancing marine pollution. Animals often ingest the tiny pieces of plastic and it can build up in their stomachs. Light pollution. The change can lead to an excessive growth of plants and their subsequent decay. Related terms: Contaminant; Marine Ecosystem; Oil Spill; Waste Management In the past few decades, plastic is one of the most dangerous pollutants that has been rapidly accumulating in the oceans. Marine Pollution is caused when harmful or even potentially harmful chemicals, particles, industrial, agricultural and residential waste, noise or may be even invasive species of plants or animals enter the ocean and disrupt the whole system. Marine pollution, explained. Ocean pollution comes from many different sources and affects marine environments around the world. However, as the atmospheric concentration of the gas is increasing, the oceans are becoming more acidic. Microplastics make up as much as 85 percent of plastic pollution found on shorelines around the world. All the industrial wastes are … When such toxins enter the body of marine animals, they accumulate in their tissues by a process called bioaccumulation. This refers to the presence of sediments, thermal pollution (cold or hot water) as well as the introduction of waste into the oceans by humans. Thermal pollution results in a temperature rise which is the main cause for the melting of the polar ice caps, which is in turn leading to a rise in the water levels. There are both natural and anthropogenic causes of water pollution. The explosions are six times louder than ships. If you don’t have the time, though, these are the main points: There are three main kinds of marine pollution: Physical pollution refers to the introduction of discarded materials into the ocean environment (study.com, 2016). Ocean pollution is therefore defined as the introduction of toxic materials such as plastic, oil, chemicals, agricultural waste, and industrial waste into the ocean waters. The change can lead to an excessive growth of plants and their subsequent decay. (Possible) Solutions to Marine Pollution #3: Technology, (Possible) Solutions to Marine Pollution #2: Use of Legislation. The carbon-dioxide present in the atmosphere dissolves in the waters of the oceans. Chemical pollution may also be contributed to by physical pollutants. Our ocean is being flooded with two main types of pollution: chemicals and trash. The toxins pass from prey to predator through the food chain and start biomagnifying at each higher level in the food chain. Patin (n.d.) notes that generally there are three main types of inputs of pollution into the ocean: direct discharge of waste into the oceans, runoff into the waters due to rain, and pollutants released from the atmosphere. Pollution Defined • The term 'pollution' describes the occurrence and inputs of wastes and the impact of these wastes on the environment. Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. The dissolved oxygen concentration in the water also decreases due to eutrophication which induces the death of marine fauna. This issue will adversely impact the corals and shellfish living in the oceans. Higher acidity.Toxic chemicals make our oceans more acidic. Oil Spills are probably the most well known of the 3 major types of pollution in the ocean. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Now that we have broadly defined the different kinds of pollution, we are in a better place to begin discussing and assessing marine pollution. What Are the Sources of Marine Pollution? But, due to rising level o… While we often hear about physical and chemical pollution, biological pollution was something that was quite new to me, and hence peaked my interest. They are all bad and they affect the environment in a bad/ negative way. These all pollutants are primarily coming from following sources such as Sewage (Waste Water), Agricultural Pollution, Oil Pollution, Radioactive Substances, River dumping, Marine Dumping etc. As a result, marine animals are harmed by the entanglement of plastics, ingestion problems, or chemicals that changes their tissue structures. The dissolved oxygen concentration in the water also decreases due to eutrophication which induces the death of marine fauna. “Zebra Mussel”.
