These parameters are important to understand the marine carbonate system in surface seawater along the North American margins. a Sea surface temperature (SST), b sea surface salinity (SSS), c total alkalinity (TA), d total dissolved inorganic carbon (DIC), e TA/SSS ratio, and f DIC/TA ratio. See the “Methods” section for details about the measurement or calculation of these parameters. To conserve space, only the 2015–2017 data are presented in their exact geographic locations on a North American ocean margin map, while earlier data are plotted at the correct latitude with a longitude offset to show that the general patterns presented here are persistent across cruises conducted in different months and years. Cruise dates and general locations are given in the “Methods” section and Supplementary Table 2.
