The biogeochemical cycles of trace elements and their isotopes (TEIs) constitute an active
area of oceanographic research due to their role as essential nutrients for marine organisms …

Phytoplankton productivity and export sequester climatically significant quantities of
atmospheric carbon dioxide as particulate organic carbon through a suite of processes …

Numerical models of ocean biogeochemistry are relied upon to make projections about the
impact of climate change on marine resources and test hypotheses regarding the drivers of …

Barium is widely used as a proxy for dissolved nutrients and particulate organic carbon
fluxes in seawater. However, these proxy applications are limited by insufficient knowledge …

Copper and Zn are trace metal micronutrients whose stable isotope systematics are
receiving increasing attention as possible paleoenvironmental tracers. However, to realise …

It is well recognized that the atmospheric deposition of iron (Fe) affects ocean productivity,
