Blue Mind: The Surprising Science That Shows How Being Near, In, On, Or Under Water Can Make You Happier, Healthier, More Connected, and Better at What You Do is a bestselling [1] book by marine biologist Wallace J. Nichols about the effects bodies of water have on human health and well-being.
In the Ocean of Night is a 1977 fix-up hard science fiction novel by American writer Gregory Benford. It is the first novel in his Galactic Center Saga . It was nominated for the Nebula Award for Best Novel in 1977, [ 1 ] and for the Locus Award the following year. [ 2 ]
This is a major process in the ocean and without vertical migration it wouldn't be nearly as efficient. The deep ocean gets most of its nutrients from the higher water column when they sink down in the form of marine snow. This is made up of dead or dying animals and microbes, fecal matter, sand and other inorganic material.
A new thermocline develops where the densest water (4 °C (39 °F)) sinks to the bottom, and the less dense water (water that is approaching the freezing point) rises to the top. Once this new stratification establishes itself, it lasts until the water warms enough for the 'spring turnover,' which occurs after the ice melts and the surface ...

In OMZs oxygen concentration drops to levels <10 nM at the base of the oxycline and can remain anoxic for over 700 m depth. [7] This lack of oxygen can be reinforced or increased due to physical processes changing oxygen supply such as eddy-driven advection, [7] sluggish ventilation, [8] increases in ocean stratification, and increases in ocean temperature which reduces oxygen solubility.
Water columns are used chiefly for environmental studies evaluating the stratification or mixing of thermal or chemically stratified layers in a lake, stream or ocean. Some of the common parameters analyzed in the water column are pH , turbidity , temperature , hydrostatic pressure , salinity , total dissolved solids , various pesticides ...
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.
