A reference to brackish water: Mixomesohaline describes salty water containing from 5 to 18 parts per thousand of dissolved salts.

A reference to salty water: Susan read in her ecology book that mixooligohaline water contained from 0.5 to 5 parts per thousand of dissolved salts, which was different to the mixomesohaline water samples tested.

A reference to brackish water containing from 18 to 30 parts per million dissolved salts: Thomas found out that mixopolyhaline water was salty and was included in the "Venice system", which was the classification of salty water based upon the proportion of chloride contained in water.

A reference to planktonic organisms living in sea water of less than five parts per thousand salinity: Grace saw a documentary on TV about oligohalabous living things found in ocean water with moderate brininess.

1. Referring to brackish water that has a salinity between 0.5 and 3.0 parts per thousand, or sea water having a salinity between 17 and 30 parts per thousand: Jane is interested in knowing more about oligohaline water, which has a low salinity level in the range of 0 - 0.5%.
2. A reference to organisms that are tolerant of only a moderate range of salinities: Oligohaline creatures are those that cannot survive in a high salinity level in oceans, but only in brackish water with a saltiness of 0.5 to 3.0 parts per thousand.

1. Pertaining to brackish water having a salinity between ten and seventeen parts per thousand, or to sea water having a salinity greater than thirty-four parts per thousand: Polyhaline water is the second highest saline region of a salt-marsh, in agreement with the Venice system for classifying brackish water.
2. Concerning extremely salt-tolerant species: One polyhaline taxonomic group is the common sea lavender of the genus Limonium, which has spikes of white or mauve flowers.

An organism that thrives in a wide range of salinities: While at the seaside one summer, Judy learned that there were many polyhalophiles that spent their lives in the ocean.

A reference to organisms that only live in oceanic waters of comparatively unchanging high salinity: Polystenohaline plants and animals exist best in sea water with a consistent and great amount of saltiness.

1. A reference to organisms that are capable of enduring only slight variations in salt concentrations: Stenohaline fish are those capable of tolerating only low densities of salt in ocean water.
2. Concerning living things that are limited to or able to live only within a narrow range of saltwater concentrations: Some stenohaline organisms must continually migrate to other water masses when the salinity level fluctuates.
3. Concerning organisms that are only able to live in water of very little gradation in salinity: Goldfish are fresh water fish and are inclined to be stenohaline and would die in an ocean because of its high salinity.

A reference to both temperature and salinity of sea water: In oceanography, thermohaline circulation relates to the joint action or variations of temperature and salinity in a water mass.

A pattern of global ocean circulative currents or courses driven by density differences in water: The Gulf Stream is one example of thermohaline circulation that is created by variations or changes in temperature and salinity in the ocean.

The vertical movement of a layer of water caused by changes in the temperature-salinity relationship resulting in it becoming heavier than the water below it: Thermohaline convection is a kind of hydrodynamic instability and arrises due to one layer becoming colder or more saline, or both, and thus more dense.
