There have been many changes over the past few decades in the physical environment and
ecosystem health of the Arctic Ocean, which is a sentinel of global warming. Bioactive trace …

Abstract The Arctic Ocean is considered a source of micronutrients to the Nordic Seas and
the North Atlantic Ocean through the gateway of Fram Strait (FS). However, there is a paucity …

Dissolved iron (DFe) and manganese (DMn) are essential micronutrients involved in vital
phytoplankton physiological pathways, and their deficit can limit primary production in …

Trace metals are essential micronutrients for phytoplankton, as well as useful tracers of
biogeochemical processes in aquatic systems. The largest Arctic rivers are known to play an …

Understanding lead exposure pathways is a priority because of its ubiquitous presence in
the environment as well as the potential health risks. We aimed to identify potential lead …

Marine particles are important regulators of the biogeochemistry of many trace elements and
isotopes in the ocean, and as such, there has been an increasing motivation to unravel the …

We describe diazotrophs present during a 2015 GEOTRACES expedition through the
Canadian Arctic Gateway (CAG) using nifH metabarcoding. In the less studied Labrador …

Early studies revealed relationships between barium (Ba), particulate organic carbon and
silicate, suggesting applications for Ba as a paleoproductivity tracer and as a tracer of …

Continental shelves are important sources of iron (Fe) in the land‐dominated Arctic Ocean.
To understand the export of Fe from the Arctic to Baffin Bay (BB) and the North Atlantic, we …

Anthropogenic Pb is widespread in the environment including remote places. However, its
presence in Canadian Arctic seawater is thought to be negligible based on low dissolved Pb …
