We propose to add dissolved oxygen sensors to the Argo (Global array of free-drifting profiling floats)float program in order to determine, on a global-scale, seasonal to decadal time-scale variations in dissolved oxygen concentrations throughout the upper ocean. Such observations are especially important to document the ocean’s expected loss of oxygen as a result of ocean warming, but there are many other benefits including the opportunity to estimate net community and export production, the assessment of changes in low oxygen regions, and improved estimates of theoceanic uptake of anthropogenic CO2. The proposed joint Argo-Oxygen program is made possible by the recent development of dissolved oxygen sensors that are both precise and stable over extended periods and can be easily integrated with the currently usedArgo floats. Results from the more than 200 oxygen equipped Argo floa.....
