Any change in the biological, chemical or physical condition of sea water is termed as marine pollution. Oil pollution from shipping route spills and disposal from transportation services, sediments due to erosion from farming, forestry and mining, cooling water from industries and power plants, municipal sewage dump that includes plastic waste and radioactive substances from industrial and military wastes are the various causes of marine pollution.

What is marine pollution?
Marine pollution occurs when harmful effects, or potentially harmful effects, can result from the entry into the ocean of chemicals, particles, industrial, agricultural and residential waste, noise, or the spread of invasive organisms. Most sources of marine pollution are land based. The pollution often comes fromnonpoint sources such as agricultural runoff and wind blown debris.
What is MARPOL working to prevent?
MARPOL, the International Convention for the Prevention of Pollution from Ships, aims to prevent marine pollution from ships by addressing various sources of pollution, including oil, chemicals, sewage, garbage, and air emissions. It establishes regulations to minimize the discharge of harmful substances into the oceans and promotes practices that protect marine environments. By implementing these measures, MARPOL seeks to safeguard marine life and ecosystems while ensuring sustainable shipping practices.
What is the pollution of Newfoundland?
Newfoundland faces various pollution challenges, including water pollution from industrial activities, agricultural runoff, and sewage discharges, which can harm aquatic ecosystems. Air pollution is also a concern, primarily due to emissions from transportation and industrial sources. Additionally, plastic waste and marine debris impact coastal areas and marine life. Efforts to monitor and address these issues are ongoing, involving government regulations and community initiatives.

What is importance of chemistry in marine engineer?
Chemistry is an important subject in Marine Engineer because it allows you to carry out the various job roles as a Marine Engineer; it gives you the knowledge to identify the many chemical problems in engineering (specifically for marine engineers: Corrosion, Pollution, etc). By understanding how to combine many different elements would lead to a longer endurance and life to the material.

Where do most of the pollution in the ocean come from?
Most ocean pollution originates from land-based sources, with significant contributions from agricultural runoff, industrial discharges, and urban stormwater. Plastics, chemicals, and fertilizers often wash into waterways and ultimately reach the ocean. Additionally, maritime activities, such as shipping and oil spills, also contribute to marine pollution. The cumulative effects of these sources severely impact marine ecosystems and wildlife.
What is the biggest cause of marine pollution?
Oil spills is the biggest cause of marine pollution. An oil spill can devastate and area of the ocean. Factories are another major cause of marine pollution.
What are facts about pollution in the Florida keys?
Pollution in the Florida Keys primarily stems from runoff, wastewater discharge, and marine debris, which threaten the delicate coral reef ecosystem. Nutrient pollution from agricultural and urban sources leads to harmful algal blooms, impacting water quality and marine life. Additionally, plastic pollution poses a significant threat, as it affects wildlife and the overall health of the marine environment. Efforts are ongoing to improve water management and reduce pollution to protect this unique ecosystem.
