Basin-scale climatological (a to d) and calculated (e to h) sea-air CO2 flux during February to May 2010. The climatological sea-air CO2 flux corresponds to that presented by Landschützer et al.7 and referenced to the year 2010. Based on this referenced sea-air CO2 flux climatology, the anomalous sea-air CO2 flux exchange for February to May 2010 was calculated (see discussion). Possitive sea-air CO2 flux denotes sea surface CO2 outgassing. The maps were generated with Matlab 2016a, the M_Map 1.7 toolbox (https://www.eoas.ubc.ca/~rich/map.html) and using the ETOPO2 Global 2 Arc-minute Ocean Depth and Land Elevation (National Geophysical Data Center/NESDIS/NOAA/U.S. Department of Commerce. 2001. ETOPO2, Global 2 Arc-minute Ocean Depth and Land Elevation from the US National Geophysical Data Center (NGDC).
