- Combed out of actually received marine datasets

- No codes; just somewhat abbreviated names
Primary Standards for Consideration
BODC - From

curiously contained only in the URLs and not in a separate list column
Unified Code for Units of Measure in OWL - From
Department of Fisheries and Oceans, Canada - Units list, but no codes
NIST Special Publication 330: the International System of Units (SI) -
Basis for all of the "units," which should properly be called "derived units"
to reflect the fact that only the SI terms are really the basic "units"
for all modern systems.
- NOTE: The SI System is officially published as ISO 1000, SI Units
and Recommendations for the Use of their Multiples and of Certain Other Units.
UDUNITS - "The UDUNITS package supports units of physical quantities
(e.g., meters, seconds). Specifically, it supports conversion between string
and binary representations of units, arithmetic manipulation of units, and
conversion of numeric values between compatible units." This "system"
doesn't even include, for example, any derived units appropriate for
concentration (i.e. quantity of substance per volume or per mass of solution)
so it probably cannot be adopted for a marine application, without major
further development or expansion. It does contain routines to convert
many current and archaic non-SI basic units to SI basic units.

This "list" includes all kinds of archaic and problematic usages, without
- NOTE: The GRIB and BUFR codes (see PARAMETERS)
are probably also relevant here, but not central until the ocean and
meteorological communities reach general agreements on parameters in general.
- ISO 31 in
Wikipedia - (Quantities and units, International Organization for
Standardization, 1992) is the most widely respected style guide for the use of
units of measurement, and formulas involving them, in scientific and
educational documents worldwide. In most countries, the notations used in
mathematics and science textbooks at schools and universities follow closely
the guidelines given by ISO 31.
