Develop and establish reference materials for nutrients in seawater (RMNS) collaborating with producers of currently available RMNS. Primary determinands are nitrate, nitrite, phosphate and silicate
Collaborate with and encourage the National Metrology Institute of Japan to complete certification of RMNS for nitrate, nitrite, phosphate and silicate
Develop new sampling and measurement protocols using the RMNS
Carry out an international collaboration exercise to verify the stability of the reference materials and test the proficiency of the new protocols
Complete a revised nutrients analysis manual
Distribute 10,000 bottles of reference material for nutrients to laboratories measuring nutrients as part of the CLIVAR Repeat Hydrography Programme to construct a global nutrient dataset referenced to the new RMNS
Promote the use of RMNS to aim for global acceptance in order to enable reliable comparability between global nutrient data sets, and to investigate the feasibility of expanding RMNS to include ammonium and dissolved organic matter
Collaborate with the ocean science community that uses chemical reference materials, including carbonate system reference material for dissolved inorganic carbon, total alkalinity and pH, and dissolved oxygen in seawater.
