Aloha CF group, I would like to propose the following standard names related to water quality measurements of the bacteria *Enterococcus *and *Clostridium perfringens*:
number_concentration_of_enterococcus_in_sea_water number_concentration_of_clostridium_perfringens_in_sea_water These are normally measured with units of CFU/100 mL, where CFU stands for Colony-Forming Units <http://en.wikipedia.org/wiki/Colony-forming_unit>. I believe the canonical units in UDUNITS parlance would translate to "m-3", which is what I find in the standard name table for other number_concentration_* quantities. For descriptions of each, I would propose: number_concentration_of_enterococcus_in_sea_water: "Number concentration" means the number of particles or other specified objects per unit volume. In this context, it represents the number of colony-forming units (CFU) of bacteria belonging to the genus Enterococcus. This indicator bacteria has been correlated with the presence of human pathogens (disease-causing organisms) and therefore with human illnesses such as gastroenteritis, diarrhea, and various infections in epidemiological studies. As such, it is commonly measured in beach water quality monitoring programs. number_concentration_of_clostridium_perfringens_in_sea_water: "Number concentration" means the number of particles or other specified objects per unit volume. In this context, it represents the number of colony-forming units (CFU) of bacteria belonging to the species Clostridium perfringens. Because this bacteria is a normal component of the human intestinal tract, its presence in samples of sea water can be used as a tracer of sewage contamination. As such, it is commonly measured in beach water quality monitoring programs. Thanks, John Maurer Pacific Islands Ocean Observing System (PacIOOS) University of Hawaii at Manoa
