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.
Plastic pollution was first found in central gyres, or rotating ocean currents in which these observations from the Sargasso Sea were included in the 1972 Journal Science. In 1986, a group of undergraduate students conducted research by recording how much plastic they came across on their ship while traveling across the Atlantic Ocean.
The plastic data collected by the students at SEA validated Maximenko's model, and researchers were able to successfully predict plastic accumulation in the North Atlantic Ocean. [ 14 ] A recent study published in December 2022 investigated the microbial communities found in the North Atlantic Garbage Patch and compared the data to the Great ...
The journal publishes research articles, review articles, and case studies that provide new insights and advances in the field of marine pollution science. [2] In addition to its regular articles, the Marine Pollution Bulletin also publishes special issues and supplements on specific topics related to marine pollution.
Marine pollution: Pathways of pollution include direct discharge, land runoff, ship pollution, atmospheric pollution and, potentially, deep sea mining. The types of marine pollution can be grouped as pollution from marine debris, plastic pollution, including microplastics, nutrient pollution, toxins and underwater noise.
