A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
The International Quiet Ocean Experiment (IQOE) is a global scientific research program aimed at improving understanding of the distributions of sounds in the ocean, and studying the effects of underwater noise pollution on marine life. The program has worked on promoting research, observations, and modelling to advance understanding of ocean ...
The research also showed that surface tension was key to the explanation through the Marangoni effect. This was suggested by two facts: (a) both mate and chalk lowered the surface tension of water, and (b) if an industrial surfactant was added on the upper reservoir, the upstream motion of particles would stop.
In 1968, the Province of Ontario and the Government of Canada set aside an area in a sparsely inhabited region of central Canada, southeast of Kenora, Ontario, which is relatively unaffected by external human influences and industrial activities, for experimental studies of the causes and control of eutrophication and other types of water pollution.
Benjamin Libet's experiment on free will shows that a readiness potential appears before the notion of doing the task enters conscious experience, sparking debate about the illusory nature of free will yet again. (1983) Vilayanur S. Ramachandran's experiment on phantom limbs with the Mirror Box throw light on the nature of 'learned paralysis ...
Space pollution — Space debris • Interplanetary contamination Resource depletion — Exploitation of natural resources • Overdrafting (groundwater) • Overexploitation Consumerism — Consumer capitalism • Planned obsolescence • Over-consumption
Drift bottle experiments are citizen science experiments in which a surveying organization throws into large bodies of water, bottles containing messages requesting finders of the bottles to return the messages to the organization with a statement of the time and place at which the bottles were found, allowing the organization to determine ...
Water research during the late 1970s and 1980s indicated that stormwater runoff was a significant cause of water quality impairment in many parts of the US. [25] Research on stormwater pollution continues in the 21st century, with findings that urban runoff is an ongoing source of water quality problems nationwide.
