Project: Metrology for ocean salinity and acidity
Higher levels of carbon dioxide (CO2) in the atmosphere lead to increased levels of CO2 dissolved in oceans, and an associated increase in acidity and salinity (the amount of salt in water). Scientists need to understand water properties such as salinity because they influence ocean circulation patterns, which affect the Earth’s climate. Salinity measurements, inferred from the conductivity of water, currently use a traditional scale not related to SI units that cannot guarantee long-term measurement traceability and stability. This research will link measurements of salinity to measurements of density, which can be traced back to SI units, thereby improving confidence in salinity measurements.
