Surface ocean pCO₂ measurements are conducted on research vessels and ships of opportunity, as well as on moorings and surface gliders. This page shows the approximate status of the global network of these observations. 

Ships of Opportunity / Volunteer Observing Ships

The map below illustrates the global network of Ships of Opportunity / Volunteer Observing Ships that collect underway pCO₂ measurements. Currently, there are ships from 14 nations around the globe contributing to this component of the ocean observing system.

Integrated Carbon Observation System - Ocean Thematic Centre (ICOS OTC)

ICOS OTC maintains an array of ocean stations and cruise tracks along which underway CO₂ observations are made. ICOS OTC is the European node of SOCONET. See the map below for the current status of the observing network.
