  2. Salt water dimmer - Wikipedia

    en.wikipedia.org/wiki/Salt_water_dimmer

    A dimmer consisted of a glass jar filled with salt water with a metal electrode at each end. As the upper electrode was moved away from the lower [3] electrode, the resistance increased and the lights got dimmer. [4] [5] [6] The brightness also depended on the concentration of salt in the water. [4]

  3. Marine microorganisms - Wikipedia

    en.wikipedia.org/wiki/Marine_microorganisms

    The suffix -omics can provide an easy shorthand to encapsulate a field; for example, an interactomics study is reasonably recognisable as relating to large-scale analyses of gene-gene, protein-protein, or protein-ligand interactions, while proteomics has become established as a term for studying proteins on a large scale.

  4. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Here, the water is chilled by Arctic temperatures. It also gets saltier because when sea ice forms, the salt does not freeze and is left behind in the surrounding water. The cold water is now more dense, due to the added salts, and sinks toward the ocean bottom. Surface water moves in to replace the sinking water, thus creating a current.

  5. Liquid rheostat - Wikipedia

    en.wikipedia.org/wiki/Liquid_rheostat

    A liquid rheostat or water rheostat [1] or salt water rheostat is a type of variable resistor. This may be used as a dummy load or as a starting resistor for large slip ring motors. In the simplest form it consists of a tank containing brine or other electrolyte solution, in which electrodes are submerged to create an electrical load .

  6. Osmoregulation - Wikipedia

    en.wikipedia.org/wiki/Osmoregulation

    Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

  7. Aquatic science - Wikipedia

    en.wikipedia.org/wiki/Aquatic_science

    Aquatic science is the study of the various bodies of water that make up our planet including oceanic and freshwater environments. [1] Aquatic scientists study the movement of water, the chemistry of water, aquatic organisms, aquatic ecosystems, the movement of materials in and out of aquatic ecosystems, and the use of water by humans, among other things.

  8. Halotolerance - Wikipedia

    en.wikipedia.org/wiki/Halotolerance

    Fields of scientific research relevant to halotolerance include biochemistry, molecular biology, cell biology, physiology, ecology, and genetics.. An understanding of halotolerance can be applicable to areas such as arid-zone agriculture, xeriscaping, aquaculture (of fish or algae), bioproduction of desirable compounds (such as phycobiliproteins or carotenoids) using seawater to support growth ...

  9. Osmotic power - Wikipedia

    en.wikipedia.org/wiki/Osmotic_power

    A 2012 study on efficiency from Yale University concluded that the highest extractable work in constant-pressure PRO with a seawater draw solution and river water feed solution is 0.75 kWh/m 3 (2.7 kJ/L) while the free energy of mixing is 0.81 kWh/m 3 (2.9 kJ/L) — a thermodynamic extraction efficiency of 91.0%.
