Abstract Subtropical gyres cover 26%–29% of the world's surface ocean and are
conventionally regarded as ocean deserts due to their permanent stratification, depleted …

The micronutrient iron is now recognized to be important in regulating the magnitude and
dynamics of ocean primary productivity, making it an integral component of the ocean's …

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 …

Abstract A Biogeochemical Southern Ocean State Estimate (B‐SOSE) is introduced that
includes carbon and oxygen fields as well as nutrient cycles. The state estimate is …

Deep-sea sediments contain high concentrations of rare earth element (REE) which have
been regarded as a huge potential resource. Understanding the marine REE cycle is …

Abstract The GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second
publicly available data product of the international GEOTRACES programme, and contains …

Zinc (Zn) is a key micronutrient for marine phytoplankton, with a global distribution that is
similar to silicic acid. The processes that govern this relationship, despite the very different …

Atmospheric dust is an important source of the micronutrient Fe to the oceans. Although
relatively insoluble mineral Fe is assumed to be the most important component of dust, a …

The neodymium (Nd) isotopic composition of seawater has been used extensively to
reconstruct ocean circulation on a variety of time scales. However, dissolved neodymium …

Barium has been used as a biogeochemical tracer for alkalinity, productivity, and riverine
inputs in the ocean, but its oceanic cycle remains poorly constrained. Barium stable isotope …
