Carbonate chemistry dynamics and carbon dioxide fluxes across the atmosphere–ice–water interfaces in the Arctic Ocean: Pacific sector of the Arctic
TLDR
In this paper, the authors show that the Arctic shelf seas (the Laptev and East-Siberian seas) may become a strong source of atmospheric CO2 because of oxidation of bio-available eroded terrestrial carbon and river transport.About:

The Arctic Ocean marine carbon cycle: evaluation of air-sea CO 2 exchanges, ocean acidification impacts and potential feedbacks
TL;DR: The capacity of the Arctic Ocean to uptake CO2 is expected to alter in response to environmental changes driven largely by climate, with the physics, biogeochemistry, and ecology of Arctic Ocean in ways that are not yet fully understood.

TL;DR: In this article, a winter time series of the inorganic carbon system above, within, and beneath the landfast sea ice of the southern Beaufort Sea confirmed that sea ice is an active participant in the carbon cycle of polar waters.
Journal ArticleDOI
Ocean acidification and biologically induced seasonality of carbonate mineral saturation states in the western Arctic Ocean
TL;DR: In this paper, a seasonal aragonite undersaturation of waters observed on the Chukchi Sea shelf is likely a recent phenomenon that results from the uptake of anthropogenic CO2 and subsequent ocean acidification, with seasonality of saturation states superimposed by biological processes.

Selected physical, biological and biogeochemical implications of a rapidly changing Arctic Marginal Ice Zone

TL;DR: A Pan-Arctic review summarizes the main changes in the Arctic ocean-sea ice-atmosphere interface, with implications for primary and secondary producers in the ice and the underlying water column as discussed by the authors.

The impact of lower sea-ice extent on Arctic greenhouse-gas exchange
Frans-Jan W. Parmentier,Torben R. Christensen,Lise Lotte Sørensen,Søren Rysgaard,Søren Rysgaard,A. David McGuire,Paul A. Miller,Donald A. Walker +7 more
TL;DR: In this article, the impact of diminishing sea-ice extent on greenhouse-gas exchange in both marine and terrestrial Arctic environments is synthesized and discussed, and the implications of an increasingly ice-free Arctic Ocean on greenhouse gas sources and sinks in the Northern high latitudes are discussed.

Relationship between wind speed and gas exchange over the ocean
TL;DR: In this paper, the influence of variability in wind speed on the calculated gas transfer velocities and the possibility of chemical enhancement of CO2 exchange at low wind speeds over the ocean is illustrated using a quadratic dependence of gas exchange on wind speed.

TL;DR: Using inorganic carbon measurements from an international survey effort in the 1990s and a tracer-based separation technique, the authors estimate a global oceanic anthropogenic carbon dioxide (CO2) sink for the period from 1800 to 1994 of 118 19 petagrams of carbon.

Assessing the eddy covariance technique for evaluating carbon dioxide exchange rates of ecosystems: past, present and future
TL;DR: The eddy covariance method is most accurate when the atmospheric conditions (wind, temperature, humidity, CO2) are steady, the underlying vegetation is homogeneous and it is situated on flat terrain for an extended distance upwind as discussed by the authors.

Observational contrains on the global atmospheric co2 budget.
TL;DR: The observed differences between the partial pressure of CO2 in the surface waters of the Northern Hemisphere and the atmosphere are too small for the oceans to be the major sink of fossil fuel CO2, and a large amount of the CO2 is apparently absorbed on the continents by terrestrial ecosystems.
