(2) The development of a coupled BGC model to the Tropical Pacific Ocean State Estimate (TPOSE) to assess temporal and spatial length scales of the climate variability. A total of 5 test floats (4 built by SIO and 1 by MRV systems) will be built, tested and then deployed along the equator of the Tropical Pacific, capable of monitoring the biogeochemical variability in the upper 2000m as part of the TPOS 2020. The new model will utilize the reliable, robust SOLOII body and add 6 BGC sensors and be Commercialize through MRV systems. The major outcomes of this project will be: (1) A new model of biogeochemical (BGC) Argo profiling float based on SIO’s SOLO-II core Argo model. This product is a powerful tool for observing system design and for advancing our understanding of the chemistry and biology of the Tropical Pacific. The model developed through this award uses physical dynamics constrained by ocean and atmospheric data between 2010-2019 to produce a high-resolution reconstruction of the interior ocean’s biogeochemistry over the time period. In addition, this award supports the development of a biogeochemical ocean model of the Tropical Pacific. This award will support the design and building of 5 BGC floats to be deployed in the Tropical Pacific as part of the TPOS in 2022. The award is to design, test, and commercialize a new model of float that can measure temperature, salinity, oxygen, pH, nitrate, chlorophyll-a, backscatter, and downwelling irradiance. This award is to advance US’s technical and commercial readiness to support the new TPOS and the larger global BGC Argo array. However, the drivers and consequences of the interannual-to-decadal variability associated with ENSO on biogeochemical processes in the region still have high uncertainty. The Tropical Pacific is the largest natural oceanic source of CO2 to the climate system and houses one of the world’s most productive ecosystems.
