3 forming effect. Aircraft sulfur and water emissions in the stratosphere tend to deplete O 3, partially offsetting the NO x-induced O 3 increases, although these effects have not been quantified. [10] Light aircraft and small commuter aircraft fly lower in the troposphere, not in the tropopause. Contrails and cirrus clouds Contrails and cirrus ...
When searching for Malaysian flight 370, substantial masses of garbage were mistaken for possible airplane parts on multiple occasions. These alarmingly huge collections of waste make one question ...
Ocean surface currents Distinctive white lines trace the flow of surface currents around the world. Visualization showing global ocean currents from January 1, 2010, to December 31, 2012, at sea level, then at 2,000 m (6,600 ft) below sea level Animation of circulation around ice shelves of Antarctica
As of 2016, there are 5.25 trillion particles of plastic pollution that weigh as much as 270,000 tonnes. Since then, studies have found that the amount of plastic particles has increased to somewhere from 15 to 51 trillion particles in 2021. [137] This plastic is taken by the ocean currents and accumulates in large vortexes known as ocean gyres ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
Marine currents can carry large amounts of water, largely driven by the tides, which are a consequence of the gravitational effects of the planetary motion of the Earth, the Moon and the Sun. Augmented flow velocities can be found where the underwater topography in straits between islands and the mainland or in shallows around headlands plays a major role in enhancing the flow velocities ...
Map of ocean currents circa 1943 This photo demonstrates the dispersal of plastic fragments of various sizes Visualization of the flow pattern of ocean pollutants. The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone.
