In-Situ Time Series Studies of Oceanic Trace Metal Variability.

We aimed at improving our understanding of mechanisms controlling chemical fluxes of trace elements through the ocean, and to exploit this knowledge to improve our understanding of oceanic processes. In general, we used the distinctive properties of elements to contribute to a better-constrained model of ocean chemistry and its effects. Having observed short-term days to weeks temporal variability in near-surface trace element concentrations see next section, we worked on ways to obtain high-resolution time-series data to understand this temporal variability. We developed a new moored trace element time-series sampler which we tested and are now deploying full-time in two key oceanic environments.
