The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

The growth of phytoplankton at high latitudes was generally thought to begin in open waters
of the marginal ice zone once the highly reflective sea ice retreats in spring, solar elevation …

Arctic Ocean primary productivity is limited by light and inorganic nutrients. With sea ice
cover declining in recent decades, nitrate limitation has been speculated to become more …

Large freshwater contributions to the Arctic Ocean from a variety of sources combine in what
is, by global standards, a remarkably small ocean basin. Indeed, the Arctic Ocean …

A comprehensive data set of dissolved organic carbon (DOC) and colored dissolved organic
matter (CDOM) absorption measurements is analysed in light of tracing the supply and …

Following worldwide bans and restrictions on the use of many persistent organic pollutants
(POPs) from the late 1970s, their regional and global distributions have become governed …

We present the first sedimentary biomarker study encompassing the entire Arctic Ocean. A
large data set of organic markers for terrigenous, petroleum and combustion inputs [alkanes …

Arctic rivers provide an integrated signature of the changing landscape and transmit signals
of change to the ocean. Here, we use a decade of particulate organic matter (POM) …

This study provides the first physically based mass‐balanced transport estimates of
dissolved inorganic nutrients (nitrate, phosphate, and silicate) for the Arctic Ocean. Using an …

Environmental context Mercury, in its methylated form, is a neurotoxin that biomagnifies in
marine and terrestrial foodwebs leading to elevated levels in fish and fish-eating mammals …
