Summary
New quality control tests for ocean optical backscattering (BBP) data collected by Biogeochemical-Argo floats are now available. These automated tests improve data quality for understanding ocean particle dynamics and the biological carbon pump.
Area of Science:
- Oceanography
- Biogeochemistry
- Data Science
Background:
- Biogeochemical-Argo floats gather extensive optical backscattering (BBP) data globally.
- BBP measurements are vital for studying ocean particle dynamics and the biological carbon pump.
- Standardized real-time quality control procedures for BBP data are currently lacking.
Purpose of the Study:
- To develop and implement a novel suite of real-time quality-control tests for BBP data.
- To enhance the reliability and usability of global BBP Argo datasets.
Main Methods:
- A new set of real-time quality-control tests for BBP data was developed by expert users and data managers.
- These tests were applied to a comprehensive snapshot of the global BBP Argo dataset.
Main Results:
- The developed tests effectively identify and flag the majority of erroneous BBP profiles within the raw dataset.
- Automated quality control significantly improves the integrity of the BBP data.
Conclusions:
- The Biogeochemical-Argo Data Management Team has approved these quality-control tests.
- These tests will be implemented by Argo Data Assembly Centres for real-time quality-controlled BBP data delivery.
- The tests show potential for application to BBP data from other platforms at depths around 1000 dbar.

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
