The Production of Methane and Nitrous Oxide Gas Standards for Scientific Committee on Ocean Research (SCOR) Working Group #143.

Abstract

The Scientific Committee on Oceanic Research (SCOR) is the leading international non - governmental organization for the promotion and coordination of international oceanographic activities, with the aim to solve conceptual and methodological problems that hinder marine research. The SCOR Working Group #143, formed in November 2013, and focuses on improving measure ments of the nitrous oxide and methane in seawater. One activity conducted was the synthesis of gas standards which were distributed to the Full Members of the Working Group and a few Associate Members as listed below. This Technical Report provides deta ils on the production of the nitrous oxide and methane standards and includes the absolute concentrations for each gas cylinder and best practice recommendations for gas regulator usage. Anyone seeking to cross - compare their own standards with these stand ards should contact one of the recipients of the standards.
