The OneArgo program builds on the internationally successful Argo program. Its goal is to extend measurements to the entire depth of the ocean and to expand biogeochemical sensors for a better understanding of the oceanic cycles of carbon, nutrients, and their role in the state of ecosystems.
The OneArgo program is to be implemented nationally and internationally within the Ocean Decade. The then fully global, multidisciplinary observation system covering the entire ocean depths will also seamlessly integrate into satellite observation systems and other in-situ elements of the global ocean observation system. To support this implementation process at the national level, a number of open scientific and technological developments related to the use of BGC floats will be addressed by 2029 in AWESOME.

The issues to be addressed are

(i) testing innovative sensor technology such as Clearwater Sensors ‘lab-on-chip sensors’ on the floats; 
(ii) improving the detection of the underwater light field by equipping the floats with radiometers and a second RBR Tridente sensor, which detects additional FDOM fluorescence channels in order to investigate DOM dynamics. This is particularly relevant in applications in the Baltic Sea; 
(iii) supporting the diversification of the sensor market by integrating lab-on-chip sensors on floats, also with regard to other parameters of the carbonate system, such as the Seabird ISFET pH (for continuous profiling) and lab-on-chip pH for an “on-board reference”. This would tie in with EU-funded projects such as TRICUSO at the European level, which are testing the NOC's lab-on-chip implementation for carbonate parameters; 
(iv) Development of new/improved quality routines based on the expanded BGC sensor technology; 
(v) Strengthening the German research landscape by providing fully equipped BGC floats in upcoming research projects such as Antarctica InSync and FUTURO.
