Working Groups and Commissions

  •  Joint Committee on the Properties of Seawater (JCS)

The Joint SCOR/IAPWS/IAPSO Committee on the Properties of Seawater (JCS) is a permanent group with limited membership whose purpose is to act as an international "point of contact" for seawater questions. It is jointly sponsored by organizations directly concerned with the properties of seawater: the Scientific Committee on Oceanic Research, the International Association for the Properties of Water and Steam, and the International Association for the Physical Sciences of the Ocean.
JCS acts as a permanent source of expertise to its parent organizations, maintains a repository of knowledge and software for the scientific community (via a web-site, www.teos-10.org), and is also a conduit for any desired communications between its parents, and out to other international organizations like the BIPM (Bureau International des Poids et Mesures), the WMO (World Meteorological Organization), and IUPAC (International Union of Pure and Applied Chemistry). In addition, JCS may from time to time summarize progress in seawater-related issues to the community at large, and suggest areas where gaps exist in the available knowledge.

  • Commission on Mean Sea Level and Tides (CMSLT)

The IAPSO Commission on Mean Sea Level and Tides (CMSLT) aims to support research into applications of sea level measurements. In addition to sponsoring meetings, the CMSLT is the body that the Permanent Service for Mean Sea Level formally reports to.
The CMSLT has always had a policy of considering as members any researchers who express interest in the topics of mean sea level and tides.

President: Gary T. Mitchum, University of South Florida, USA

  • Tsunami Commission (Joint with IASPEI and IAVCEI)

The IUGG Tsunami Commission (IUGG/TC) is an Inter-Association Commission responsible for international coordination of tsunami related meetings, research, and publications. It is jointly sponsored by IASPEI, IAPSO and IAVCEI and was established at the 12th General Assembly of IUGG in Helsinki, Finland in 1960 to promote the exchange of scientific and technical information about tsunamis.

The IUGG/TC membership comprises an international group of scientists concerned with various aspects of tsunamis, including an improved understanding of the dynamics of generation, propagation and coastal run-up and the consequences to society of the tsunami hazard.

IUGG Tsunami Commission website contains the current information about the Commission activities and upcoming meetings.
