CLIVAR Repeat Hydrography Sections
A subset of the planned CLIVAR Repeat Hydrography Program sections is shown above. The US component of this international program is supported jointly by NSF and NOAA. The goal of this program is to repeat key full-depth hydrographic sections in the global ocean at intervals of ~10 years in order to detect decadal-scale changes in ocean circulation, chemistry, physics and biology.
