Excess radiocarbon constraints on air-sea gas exchange and the uptake of CO2 by the oceans
[1] We re-assess the constraints that estimates of the global ocean excess radiocarbon inventory (I) place on air-sea gas exchange. We find that the gas exchange scaling parameter aq cannot be constrained by I E alone. Non-negligible biases in different global wind speed data sets require a careful adaptation of aq to the wind field chosen. Furthermore, aq depends on the spatial and temporal re...
متن کاملAdvances in quantifying air-sea gas exchange and environmental forcing.
The past decade has seen a substantial amount of research on air-sea gas exchange and its environmental controls. These studies have significantly advanced the understanding of processes that control gas transfer, led to higher quality field measurements, and improved estimates of the flux of climate-relevant gases between the ocean and atmosphere. This review discusses the fundamental principl...
متن کاملAn inverse approach to estimate bubble-mediated air-sea gas flux from inert gas measurements
An ocean general circulation model (oGCM) was used in concert with a global database of inert gas measurements (Ne, Ar, N2/Ar and Kr/Ar) to constrain the magnitude of bubble mediated air-sea gas flux. We illustrate the inverse method using a simple bubble model that includes two end member types of bubbles: small bubbles that completely dissolve, and larger bubbles that briefly are submerged an...
متن کاملSpray-Mediated Air-Sea Gas Exchange: The Governing Time Scales
It is not known whether sea spray droplets can act as agents that influence air-sea gas exchange. We begin to address that question here by evaluating the time scales that govern spray-mediated air-sea gas transfer. To move between the interior of a spray droplet and the atmospheric gas reservoir, gas molecules must complete three distinct steps: (1) Gas molecules must mix between the interior ...
متن کاملThe role of bubbles during air-sea gas exchange
The potential for using the air-sea exchange rate of oxygen as a tracer for net community biological production in the ocean is greatly enhanced by recent accuracy improvements for in situ measurements of oxygen on unmanned platforms. A limiting factor for determining the exchange process is evaluating the air-sea flux contributed by bubble processes produced by breaking waves, particularly dur...
