- Abstract:
- Ocean salinity is a key variable in the reconstruction of past climates and is routinely used as input to ocean and atmosphere models. This proposal seeks to develop new proxies to reconstruct past salinity at greater precision than presently possible. This work will also test the influence of salinity on existing trace-metal proxies such as the Mg/Ca paleothermometer. Systematic relationships between salinity and trace-metals in inorganically grown carbonates suggest that a biogenic salinity signal will also exist. This signal will be investigated using planktic forams from the Mediterranean and corals from the Red Sea, both spanning a wide range of salinity. Changes in fractionation of Li, Mg, and Ca isotopes in these and inorganic calcites will also be investigated. Attempts to understand results will be made with observation and modelling techniques.
