In this data report, we present carbon stable isotope (δ13C) analy-ses of dissolved inorganic carbon (DIC) in interstitial water sam-ples from Integrated Ocean Drilling Program Expedition 303 Sites U1305, U1306, and U1307 on the Eirik Drift in the Labrador Sea. A total of 84 interstitial water samples extracted on board were analyzed postcruise in this study. The low- to intermediate-resolu-tion (from ~3 to 30 m interval) data allow us to identify down-hole trends in δ13CDIC. Our results show a downhole decreasing trend in δ13CDIC in the upper ~50–80 meters below seafloor (mbsf) at the three sites studied. The most depleted δ13CDIC values occur at 51.4, 85.8, and 79.2 mbsf at Sites U1305, U1306, and U1307, respectively. Below the depths of δ13CDIC minima, δ13CDIC values generally increase toward the bottom of the cored interval.
