For example, microplastics can be found on sandy beaches [78] and surface waters [79] as well as in the water column and deep sea sediment. Microplastics are also found within the many other types of marine particles such as dead biological material (tissue and shells) and some soil particles (blown in by wind and carried to the ocean by rivers).
Microplastics are everywhere. They have been found on the peak of Mount Everest and in creatures inhabiting the deepest trenches of the sea.They’re in bottled water, human placentas and breast ...
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...

Microplastics are extremely difficult to track and clean up through conventional methods
Plastic marine debris, most notably microplastics, accumulates in aquatic environments and serves as a habitat for various types of microorganisms, including bacteria and fungi. [1] [2] As of 2022, an estimated 51 trillion microplastics are floating in the surface water of the world's oceans. [3]
Denser material that is thought to exist under the surface of the ocean includes plastic called polyethylene terephthalate that is used to make soft drink and water bottles. [6] However, these denser plastics are not observed in the North Atlantic garbage patch because the methods to collect samples only capture the surface microplastics.
The surface salinity of the ocean is a key variable in the climate system when studying the global water cycle, ocean–atmosphere exchanges and ocean circulation, all vital components transporting heat, momentum, carbon and nutrients around the world. [84] Cold water is more dense than warm water and salty water is more dense than freshwater.
