IAPSO promotes the study of the oceans and its interactions at the sea floor, coastal, and atmospheric boundaries using mathematics, physics, and chemistry.
IAPSO arranges biennial scientific assemblies, oversees working groups, funds best practice study groups, awards medals, and has an active early career network.
IAPSO is one of the eight associations of the International Union of Geodesy and Geophysics (IUGG), which in turn is a member of the International Science Council (ISC).
