Natural abundance ratios of isotopocules, molecules that have the same chemical
constitution and configuration, but that only differ in isotope substitution, retain a record of a …

As a highly productive, seasonally ice-covered sea with an expansive shallow continental
shelf, the Chukchi Sea fuels high rates of sedimentary denitrification. This contributes to its …

The spatial and vertical distribution of colored dissolved organic matter (CDOM) in the North
Pacific Ocean, Bering, Chukchi and Beaufort Seas was investigated with respect to water …

Abstract We collected Arctic Ocean water column samples for methane (CH4) and nitrous
oxide (N2O) analysis on three separate cruises in the summer and fall of 2015, covering a∼ …

Dissolved methane and nitrous oxide in seawater were measured along a 6700km transect
of the North-West Passage between the North Atlantic Ocean and Beaufort Sea in the Arctic …

The oceanic nitrogen cycle is critically important for the partitioning of greenhouse gases
between ocean and atmosphere. Baffin Bay connects ocean regions that are major sources …

Between 2015 and 2018, we collected approximately 2,000 water column measurements of
methane (CH4) and nitrous oxide (N2O) concentrations in the North American Arctic Ocean …

Human activities are changing the Arctic environment at an unprecedented rate resulting in
rapid warming, freshening, sea ice retreat and ocean acidification of the Arctic Ocean. Trace …

Ocean–atmosphere gas exchange in the Arctic Ocean is sensitive to global warming
because the decrease of sea‐ice covered area enhances the exchange. Melting sea ice …

Nitrous oxide (N2O) is a strong greenhouse gas and stratospheric ozone‐depleting
substance. Around 20% of global emissions stem from the ocean, but current estimates and …
