Oceanic influence on the global hydrological cycle: Quantifying the global salinity cycle - Ocean-atmosphere freshwater fluxes
Supervisors: Susan Wijffels (CSIRO), A/Prof Nathan Bindoff (UTAS), and Dr Helen Phillips (UTAS)
Considerable changes to the global hydrological cycle are anticipated as a consequence to climate change, documented by the IPCC. Climate model projected changes indicate both an increase to mean and extreme global
precipitation, with corresponding ocean circulation changes expected,
linked through the global hydrological cycle.
This project will look at the observational record of global ocean
salinity. Firstly, a comparison to available ocean climatology products
will be developed against the new Argo global dataset with an intention
on diagnosing salinity trends and variability in the global ocean. The
next stage will involve validating ocean observations with atmospheric
observations of the hydrological cycle - with the intention of
diagnosing inconsistencies within ocean historical data. Once the
observational record is well understood, the latest IPCC AR4 climate
model representations of both the 20th century and 21st century
projected climate will then be examined.
