  abstract = {{A}utomated instruments on board {V}olunteer {O}bserving {S}hips ({VOS}) have provided high-frequency p{CO}(2) measurements over basin-wide regions for a decade or so. {I}n order to estimate regional air-sea {CO}2 fluxes, it is necessary to interpolate between in-situ measurements to obtain maps of the marine p{CO}(2). {S}uch an interpolation remains, however, a difficult task because {VOS} lines are too distant from each other to capture the high p{CO}(2) variability. {R}elevant physical parameters available at large scale are thus necessary to serve as a guide to estimate the p{CO}(2) values between the {VOS} lines. {S}atellites do not measure p{CO}(2) but they give access to parameters related to the processes that control its variability, such as sea surface temperature ({SST}). {I}n this paper we developed a method to compute p{CO}(2) maps using satellite data ({SST} and {CHL}, the chlorophyll concentration), combined with a climatology of the mixed-layer depth ({MLD}). {U}sing 15 401 measurements of surface p{CO}(2) acquired in the {N}orth {A}tlantic between {UK} and {J}amaica, between {J}une 1994 and {A}ugust 1995, we show that the parameterization of p{CO}(2) as a function of {SST}, {CHL} and {MLD} yields more realistic p{CO}(2) values than parameterizations that have been widely used in the past, based on {SST}, latitude, longitude or {SST} only. {T}his parameterization was then used to generate seasonal maps of p{CO}(2) over the {N}orth {A}tlantic. {R}esults show that our approach yields the best marine p{CO}(2) estimates, both in terms of absolute accuracy, when compared with an independent data set, and of geographical patterns, when compared to the climatology of {T}akahashi et al. (2002). {T}his suggests that monitoring the seasonal variability of p{CO}(2) over basin-wide regions is possible, provided that sufficient {VOS} lines are available.},
