Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

The element silicon (Si) is required for the growth of silicified organisms in marine
environments, such as diatoms. These organisms consume vast amounts of Si together with …

The micronutrient iron plays a major role in setting the magnitude and distribution of primary

Anthropogenic mercury (Hg) undergoes long-range transport to the Arctic where some of it is
transformed into methylmercury (MeHg), potentially leading to high exposure in some Arctic …

We present full water depth sections of size‐fractionated (1–51 μm;> 51 μm) concentrations
of suspended particulate matter and major particle phase composition (particulate organic …

The Siberian rivers supply large amounts of freshwater and terrestrial derived material to the
Arctic Ocean. Although riverine freshwater and constituents have been identified in the …

The Arctic faces many environmental challenges, including the continued exploitation of its
mineral resources such as nickel (Ni). The responsible development of Ni mining in the …
