        <rdfs:comment>A concentration is a measurement of how much of a given substance (solute) is mixed with another substance (solvent). Concentrations will have 2 dimensions: 
SOLUTE [mole-amounts, mass, ionic charge, volume] PER SOLUTION [volume, mass]. Other numerators or denominators may also be possible (tbd)

The denominator (solution) is most commonly a volume. But for natural water bodies (e.g. ocean), mass may be used to remove the effects of temperature and pressure on volume when these are significant.  Accurate conversions between units are not always straightforward, and must take into account temperature and pressure at which the sample was collected. 

When solute mass or ionic charge is used (numerator), unit conversions need access to other information e.g, the periodic table of elements, or valence states.

Concentrations also include  the mixtures of suspended particulates or their components in a volume (e.g. of water). These are non-homogeneous solutions. The protocol should make clear how mixtures are defined.</rdfs:comment>

        <rdfs:comment>Solid material suspended in natural water. Usually, this is a mixture of inorganic and organic material, living and dead. Suspended solids are not dissolved. They are particles of various sizes and buoyancy. Usually, the material is collected from a volume of water, and the collection protocol should specify the size or type of filter used to separate the suspended material from the water and dissolved material.</rdfs:comment>
