The Biogeochemical-Argo program (BGC-Argo) is a new profiling-float-based, ocean wide, and distributed monitoring which tightly linked to, has benefited significantly from, the Argo program. community recommended for BGC-Argo addition of six measurements in to pressure, temperature salinity measured by Argo, include oxygen, pH, nitrate, downwelling light, chlorophyll fluorescence optical backscattering coefficient. purpose this enable biogeochemistry health, particular, monitor major...
The Southern Ocean Carbon and Climate Observations Modeling (SOCCOM) project has deployed 194 profiling floats equipped with biogeochemical (BGC) sensors, making it one of the largest contributors to global BGC-Argo. Post-deployment quality control (QC) float-based oxygen, nitrate, pH data is a crucial step in processing dissemination such data, as situ chemical sensors remain early stages development. In calibration on using atmospheric reanalysis empirical algorithms can bring accuracy...
Biogeochemical-Argo floats are collecting an unprecedented number of profiles optical backscattering measurements in the global ocean. Backscattering (BBP) data crucial to understanding ocean particle dynamics and biological carbon pump. Yet, so far, no procedures have been agreed upon quality control BBP real time.Here, we present a new suite real-time quality-control tests apply them current Argo dataset.

Abstract Measurements of pH and nitrate from the Southern Ocean Carbon Climate Observations Modeling array profiling floats were used to assess ratios dissolved inorganic carbon (DIC) (NO 3 ) uptake during spring summer bloom period throughout Ocean. Two hundred forty‐three periods observed by 115 30°S 70°S. Similar calculations made using Takahashi surface DIC climatology. To separate effects atmospheric CO 2 exchange mixing phytoplankton uptake, changes in waters (ΔDIC/ΔNO computed...
Biogeochemical- (BGC-) Argo aims to deploy and maintain a global array of autonomous profiling floats monitor ocean biogeochemistry. With over 250,000 profiles collected so far, the BGC-Argo network is rapidly expanding toward target sustained fleet 1,000 floats. These prioritize measurement six key properties: oxygen, nitrate, pH, chlorophyll-a, suspended particles, downwelling light. To assess current biogeochemical state ocean, its variability, trends with confidence, it crucial quality...

Abstract Sensors that use ultraviolet (UV) light absorption to measure nitrate in seawater at situ temperatures require a correction the calibration coefficients if and sample are not identical. This is mostly due bromide molecule, which absorbs more UV as temperature increases. The current applied spectrophotometer (ISUS) submersible analyzer (SUNA) sensors generally follows Sakamoto et al. (2009, Limnol. Oceanogr. Methods 7, 132–143). For waters warmer than temperature, this model can lead...
Understanding the size and future changes of natural ocean carbon sinks is critical for projection atmospheric CO 2 levels. The magnitude Southern Ocean flux has varied significantly over past decades but mechanisms behind this variability are still under debate. While high accuracy observations, e.g. from ships moored platforms, important to improve models they limited through space time. Observations autonomous platforms with emerging biogeochemical capabilities, profiling floats, provide...
