    en.wikipedia.org/wiki/Marine_debris

    Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines , frequently washing aground, when it is known as beach litter or tidewrack.

    There are three primary ways the public can learn about or participate in beach cleaning: educational programs, awareness campaigns, and volunteering. All modes of public engagement can increase awareness of the issue of marine litter, educate participants about marine litter and ocean conservation, and motivate behavior change.

  5. Ecological pyramid - Wikipedia

    en.wikipedia.org/wiki/Ecological_pyramid

    Pyramids of energy are normally upright, but other pyramids can be inverted (pyramid of biomass for marine region) or take other shapes (spindle shaped pyramid). Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat ...

  6. Garbage patch - Wikipedia

    en.wikipedia.org/wiki/Garbage_patch

    A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...

  7. Marine plastic pollution - Wikipedia

    en.wikipedia.org/wiki/Marine_plastic_pollution

    Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic.

  8. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    The marine carbon cycle is a central to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.

  9. Marine energy - Wikipedia

    en.wikipedia.org/wiki/Marine_energy

    Marine energy or marine power (also sometimes referred to as ocean energy, ocean power, or marine and hydrokinetic energy) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world's oceans creates a vast store of kinetic energy, or energy in motion.
