Ship-based hydrography is the only method for obtaining high-quality measurements with high spatial and vertical resolution of a suite of physical, chemical, and biological parameters over the full ocean water column, and in areas of the ocean inaccessible to other platforms. Global hydrographic surveys have been carried out approximately every decade since the 1970s through research programs such as GEOSECS (Geochemical Ocean Sections Study), TTO/SAVE Transient Tracers in the Ocean (/South Atlantic Ventilation Experiment), WOCE/JGOFS (World Ocean Circulation Experiment/Joint Global Ocean Flux Study), and CLIVAR (Climate Variability and Predictability). It is time to consider how future surveys can build on these foundations to create a coordinated network of sustained ship-based hydrographic sections that will become an integral component of the ocean observing system. This white paper provides scientific justification and guidelines for the development of a regular and coordinated global survey.
