The Joint Committee on Seawater of the International Association for the Properties of Water and Steam (IAPWS), SCOR, and the International Association for the Physical Sciences of the Ocean (IAPSO) was formed following the completed work of SCOR/IAPSO WG 127 on Thermodynamics and Equation of State of Seawater, which created the Thermodynamic Equation of State-2010 (TEOS-10). It was recognized at that time that progress needed to continue on the development of relationships between temperature and salinity of seawater outside the range of previously available equations.
The work of the Committee is mostly conducted at annual IAPWS meetings. The Committee has subdivided its work into task groups: (1) salinity/density, (2) pH, (3) moist air, and (4) chemical speciation. The Committee also has expertise in thermodynamics, numerical modeling and applications, and software. The Committee includes representation from industry.

Terms of Reference
- To act as a ‘point of contact’ for issues related to the bulk properties of seawater.
- To maintain and update documents, websites and software of TEOS-10 and other standards.
- To encourage the uptake of TEOS-10 and other standards by the oceanographic community by acting as a source of advice.
- To globally coordinate research and the development of standards related to properties of seawater across different scientific communities.
- To identify developing needs for standards and encourage research in those areas, through small collaborations, more formal Working Groups, conference sessions, or other avenues.
- To issue reports or other documents from time to time on issues relating to the bulk properties of seawater.
- To work toward international and interdisciplinary uniformity and consistency of the standards and measurement procedures used in oceanography.
