International Association for the Physical Sciences of the Oceans (IAPSO)

At the First IUGG General Assembly (Rome, 1922), the Section d’Océanographie became one of the constituent Sections of the Union. At the IV IUGG General Assembly (Stockholm, 1930) it became the International Association of Physical Oceanography.
It took its present name at the XIV IUGG General Assembly (Zurich, 1967).

IAPSO promotes the study of the physical sciences of the oceans and the interactions taking place at the sea floor, coastal, and atmospheric boundaries by organising international forums and publishing written materials for ocean scientists throughout the world. Commissions, sub-committees, and workshops encourage new and advanced international research activities. In addition, IAPSO provides basic services such as the Permanent Service for Mean Sea Level and the IAPSO Standard Seawater Service. IAPSO collaborates closely with UNESCO’s Intergovernmental Oceanographic Commission (IOC) and ISC’s Scientific Committee on Oceanic Research (SCOR). The president of IAPSO is a member of the SCOR Executive Committee as is the president of IAMAS.

IAPSO has International Commissions on the following topics:

  • Ice-Ocean Interactions (Joint with IACS)
  • Mean Sea Level and Tides

  • Properties of sea water (Joint with SCOR and IAPWS)
  • Tsunami Commission (Joint with IASPEI and IAVCEI)

Active working group (joint with SCOR):

  • IAPSO Early Career Scientists Working Group
