The World Ocean Circulation Experiment WOCE was the largest internationally coordinated oceanographic program ever conducted. It provides global ocean observations of unprecedented extent and quality for the decade from 1988 until 1998. 

The World Ocean Circulation Experiment (WOCE) was a part of the World Climate Research Programme (WCRP). Nearly 30 countries contributed resources to make unprecedented in-situ and satellite observations of the global ocean between 1990 and 1998. The WOCE Hydrographic Program (WHP) encompassed a range of physical and chemical measurements collected from research vessels mainly by means of Conductivity/Temperature/Depth (CTD) profilers and rosette water samplers. The WHP One-Time Survey provided high-quality basin-crossing ocean sections, along which temperature, salinity, dissolved oxygen, nutrients, CO2, CFCs and other parameters were measured.
