Última The Spatiotemporal Dynamics of the Sources and Sinks of CO2 in the Global Coastal Ocean ArchiMer Roobaert, Alizee; Laruelle, Goulven G.; Landschuetzer, Peter; Gruber, Nicolas; Chou, Lei; Regnier, Pierre. In contrast to the open ocean, the sources and sinks for atmospheric carbon dioxide (CO2) in the coastal seas are poorly constrained and understood. Here we address this knowledge gap by analyzing the spatial and temporal variability of the coastal air-sea flux of CO2 (FCO2) using a recent high-resolution (0.25 degrees) monthly climatology for coastal sea surface partial pressure in CO2 (pCO(2)). Coastal regions are characterized by CO2 sinks at temperate and high latitudes and by CO2 sources at low latitude and in the tropics, with annual mean CO2 flux densities comparable in magnitude and pattern to those of the adjacent open ocean with the exception of river-dominated systems. The seasonal variations in FCO2 are large, often exceeding 2 mol C m(-2)... Tipo: Text Palavras-chave: Coastal seas; Air-sea CO2 exchange; Seasonality; Ocean carbon cycle; Continental shelves.

In this study, we present the first combined open- and coastal-ocean pCO(2) mapped monthly climatology (Landschutzer et al., 2020b, https://doi.org/10.25921/qb25-f418, https://www.nodc.noaa.gov/ocads/oceans/MPI-ULB-SOM_FFN_clim.html, last access: 8 April 2020) constructed from observations collected between 1998 and 2015 extracted from the Surface Ocean CO2 Atlas (SOCAT) database. We combine two neural network-based pCO(2) products, one from the open ocean and the other from the coastal ocean, and investigate their consistency along their common overlap areas. While the difference between open- and coastal-ocean estimates along the overlap area increases with latitude, it remains close to 0 mu atm globally. Stronger discrepancies, however, exist on the...
