[4] [5] [6] The brightness also depended on the concentration of salt in the water. [4] The switchboard built at Her Majesty's Theatre, London in 1897 had a dimmer scale of 0 to 10, whereas gas lighting only had 3 levels. [1] The salt water need to be refilled regularly, the metal electrodes corroded, and the dimmers emitted a strong smell.
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 .
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.
The on-board lab can perform chemical analysis of those water samples. It also has transducers for measuring ocean currents, sub-bottom profiling, and deep water bathymetry . [ 20 ] In response to the Deepwater Horizon oil spill , the vessel was reassigned to environmental monitoring of affected areas and to track underwater plumes of oil.
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.
The tables below present an example of an artificial seawater (35.00‰ of salinity) preparation devised by Kester, Duedall, Connors and Pytkowicz (1967). [1] The recipe consists of two lists of mineral salts, the first of anhydrous salts that can be weighed out, the second of hydrous salts that should be added to the artificial seawater as a solution.

In oceanography, a halocline (from Greek hals, halos 'salt' and klinein 'to slope') is a cline, a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water. [1] Because salinity (in concert with temperature ) affects the density of seawater , it can play a role in its vertical stratification .
