Air-Sea CO2 Exchange and Carbon Dynamics in Foxe Basin: Findings from a 2023 Oceanographic Survey
… role in climate by removing large amounts of carbon dioxide (CO2) from the atmosphere through air-sea gas exchange. This process is particularly important in polar oceans, where sea-ice formation releases brine to the water column below and can create dense waters that sink and sequester …

Interactions between rivers and coastal margins in the Alaskan Arctic
Arctic coastal margins serve as the interface between Arctic terrestrial and oceanic carbon reservoirs. Characterized by extreme seasonality and annual variability, Alaskan Arctic coastal margins only receive riverine input of terrestrial organic material from late spring through late summer. This …

Radiocarbon (Δ14C) and Stable Carbon (δ13C) Isotopic Composition of Dissolved Inorganic Carbon (DIC) in Baffin Bay
… half of all anthropogenic fossil fuel carbon dioxide (CO2) emissions have been absorbed by the oceans. Air-sea gas exchange of CO2 and the buffering capacity of seawater allows the oceans to store significant amounts of dissolved inorganic carbon (DIC; ~38,000 GtC). The Arctic Ocean is …

Tracing carbon flows through Arctic and alpine watersheds
… stability. Chapter two investigates how fresh carbon (C) influences SOM cycling in soils underlying two dominant Arctic plant species. We amended soils colonized by Eriophorum vaginatum—a tussock-forming sedge—and Betula nana—a competitive dwarf shrub—with glucose, and employed stable isotope …

Integrated Terrestrial and Hydrological Carbon Budgets in High Arctic Watersheds
The movement of carbon between terrestrial and aquatic stores and the atmosphere exerts an important control on atmospheric greenhouse gas concentrations, and thus the extent of climate change. Understanding the magnitude of these carbon fluxes, and their controls, is important for informing …
