AICE Marine Ch7(solute) Vocab

Solute

Solid that dissolves in a solvent

Salinity

Measure of the quantity of dissolved solids in ocean water, represented by parts per thousand(ppt), or 0/00

Hypersaline

When a body of water has a salinity level greater than 38 0/00

Hyposaline

Salinity less than

Acidic

A pH below 7

Turbulence

Irregular changes in the speed and direction of a fluid’s movement

Solution

A mixture of a solute dissolved in a solvent

Precipication

Water falling from the atmosphere(usually), to the earth’s surface as rain, sleet, snow, or hail.

Halocline

Layer of water where salinity changes quickly with depth

Alkaline

pH above 7

Dissolved Oxygen(DO)

Concentration of oxygen dissolved in a solution.

Solubility

Ability of a solute to dissolve within a solvent(such as water).

Run-off

The flow of water from land caused by precipitation

Thermocline

Layer in water where temperature drops quickly as you go deeper.

Neutral

pH that equals/ is very close to 7.

Phytoplankton

Microscopic photosynthetic organisms that live in the upper sunlit layers of water.

Dissolution

The process of being dissolved.

Evaporation

Change in state from liquid to gas below the boiling point of a substance.

pH

Numeric value expressing the acidity or alkalinity of a solution on a logarithmic scale.

pH scale

Logarithmic scale that measures the ratio of hydrogen ions to hydroxide ions.

Oxygen minimum layer

The layer within the ocean where the concentration of oxygen is at its lowest, usually found between the photic zone and between 100-1000m.
