TLDR
A temporally and spatially resolved estimate of the global surface-ocean CO2 partial pressure field and the sea-air CO2 flux is presented, obtained by fitting a simple data-driven diagnostic model of ocean mixed-layer biogeochemistry to surface-of-the-atmosphere (CO2) partial pressure data from the SOCAT v15 database.Abstract:
A temporally and spatially resolved estimate of the global surface-ocean CO2 partial pressure field and the sea–air CO2 flux is presented, obtained by fitting a simple data-driven diagnostic model of ocean mixed-layer biogeochemistry to surface-ocean CO2 partial pressure data from the SOCAT v15 database Results include seasonal, interannual, and short-term (daily) variations In most regions, estimated seasonality is well constrained from the data, and compares well to the widely used monthly climatology by Takahashi et al (2009) Comparison to independent data tentatively supports the slightly higher seasonal variations in our estimates in some areas We also fitted the diagnostic model to atmospheric CO2 data The results of this are less robust, but in those areas where atmospheric signals are not strongly influenced by land flux variability, their seasonality is nevertheless consistent with the results based on surface-ocean data From a comparison with an independent seasonal climatology of surface-ocean nutrient concentration, the diagnostic model is shown to capture relevant surface-ocean biogeochemical processes reasonably well Estimated interannual variations will be presented and discussed in a companion paperread more

TL;DR: In this paper, the benefits of using satellite data streams for ocean acidification and carbonate system studies are discussed, as well as opportunities on the horizon for using new satellite sensors with increased spectral, temporal, and/or spatial resolution.

TL;DR: It is highlighted that inclusion of isotope variables within the model, and use of the associated observations, allowed us to better constrain the range for biogeochemical processes parameters than compared to running the MCMC optimisation without isotopes included.

TL;DR: In this paper, a regional high-resolution ocean biogeochemical model for the Gulf of Mexico (GoM) is presented to describe seasonal patterns in surface pressure of CO2 (pCO2), aragonite saturation state (Ar ), and sea-air CO2 flux.

Robust Constraints on Past CO2 Climate Forcing From the Boron Isotope Proxy
TL;DR: In this paper, a linear relationship between ocean pH change and CO2 radiative forcing was shown to be the dominant control that effectively sets CO2 forcing on orbital timescales, as is evident from independent late Pleistocene reconstructions of pH and CO 2.

Jenne,Dennis Joseph +21 more
TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.

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.
