The Arctic Ocean has experienced rapid warming and sea ice loss in recent decades,
becoming the first open-ocean basin to experience widespread aragonite undersaturation …

Arctic warming is occurring at a much faster rate than in other parts of the globe, with
potentially devastating consequences for the diverse array of species within ecologically …

Rapid climate warming and sea-ice loss have induced major changes in the sea surface
partial pressure of CO2 (p CO 2). However, the long-term trends in the western Arctic Ocean …

Less than three decades ago only a small fraction of the Arctic Ocean (AO) was ice free and
then only for short periods. The ice cover kept sea surface pCO2 at levels lower relative to …

Recent rapid sea‐ice changes in the Arctic Ocean have been widely considered to alter
phytoplankton bloom timing and primary production, but the magnitude and regionality of …

Rapid warming and sea-ice loss in the Arctic Ocean are among the most profound climatic
changes to have occurred in recent decades on Earth. Arctic Ocean biological production …

Abstract The Arctic Ocean has turned from a perennial ice‐covered ocean into a seasonally
ice‐free ocean in recent decades. Such a shift in the air‐ice‐sea interface has resulted in …

Anthropogenic CO2 uptake drives ocean acidification and so decreases the calcium
carbonate (CaCO3) saturation state (Ω). Undersaturation of surface water with respect to …

While mercury occurs naturally in the environment, human activity has significantly disturbed
its biogeochemical cycle. Inorganic mercury entering aquatic systems can be transformed …

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 …
