This is a somewhat belated announcement of the most recent standard name table update. The current version is now V44, dated 23 May 2017. The changes have also been published in the NERC Vocabulary Server. They are listed in full at the end of this message.
The next update to standard names is planned for 26th June 2017.
V44 standard name changes
1. New names
a. Biogeochemistry names proposed by Paul Durack for the CMIP6 OMIP experiment
mole_concentration_of_carbonate_expressed_as_carbon_at_equilibrium_with_pure_aragonite_in_sea_water (canonical units: mol m-3)
mole_concentration_of_carbonate_expressed_as_carbon_at_equilibrium_with_pure_calcite_in_sea_water (canonical units: mol m-3)
b. Physics names proposed by Stephen Griffies and Jonathan Gregory for the CMIP6 OMIP experiment
specific_heat_capacity_of_sea_water (canonical units: J kg-1 K-1)
No new aliases were added in this version of the standard name table.
3. Modifications to definitions of existing names
a. Definitions updated following discussion of OMIP biogeochemistry names
The definitions of six dissolved inorganic silicon/phosphorus names were modified.
For the silicon names, the final sentence of each definition was changed from ' "Dissolved inorganic silicon" means silicate ions in solution' to ' "Dissolved inorganic silicon" means the sum of all inorganic silicon in solution (including silicic acid and its first dissociated anion SiO(OH)3-).'
For the phosphorus names, the final sentence of each definition was changed from ' "Dissolved inorganic phosphorus" means phosphate ions in solution' to ' "Dissolved inorganic phosphorus" means the sum of all inorganic phosphorus in solution (including phosphate, hydrogen phosphate, dihydrogen phosphate, and phosphoric acid).'
The names affected were:
The definition of the name sea_water_ph_reported_on_total_scale was modified to replace the word 'activity' with 'concentration' in the sentence ' sea_water_pH_reported_on_total_scale' is the measure of acidity of seawater, defined as the negative logarithm of the concentration of dissolved hydrogen ions plus bisulfate ions in a sea water medium; it can be measured or calculated; when measured the scale is defined according to a series of buffers prepared in artificial seawater containing bisulfate.'
b. Definitions updated following discussion of OMIP physics names
The sentence 'Brunt-Vaisala frequency is also sometimes called "buoyancy frequency" and is a measure of the vertical stratification of the medium' was added to the definitions of two names:
