  abstract = {{W}e provide the first continuous measurements of isotopic composition ({D} and {O}-18) of water vapor over the subtropical {E}astern {N}orth {A}tlantic {O}cean from mid-{A}ugust to mid-{S}eptember 2012. {T}he ship was located mostly around 26 degrees {N}, 35 degrees {W} where evaporation exceeded by far precipitation and water vapor at 20m largely originated from surface evaporation. {T}he only large deviations from that occurred during a 2 day period in the vicinity of a weak low-pressure system. {T}he continuous measurements were used to investigate deuterium excess (d-excess) relation to evaporation. {D}uring 25 days d-excess was negatively correlated with relative humidity (r(2)=0.89). {M}oreover, d-excess estimated in an evaporative model with a closure assumption reproduced most of the observed variability. {F}rom these observations, the d-excess parameter seems to be a good indicator of evaporative conditions. {W}e also conclude that in this region, d-excess into the marine boundary layer is less affected by mixing with the free troposphere than the isotopic composition. {F}rom our data, the transition from smooth to rough regime at the ocean surface is associated with a d-excess decrease of 5, which suggests the importance of the ocean surface roughness in controlling d-excess in this region.},
