Abstract:
In this data report, we present carbon stable isotope (delta (super 13) C) analyses of dissolved inorganic carbon (DIC) in interstitial water samples 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-resolution (from approximately 3 to 30 m interval) data allow us to identify downhole trends in delta (super 13) C (sub DIC) . Our results show a downhole decreasing trend in delta (super 13) C (sub DIC) in the upper approximately 50-80 meters below seafloor (mbsf) at the three sites studied. The most depleted delta (super 13) C (sub DIC) values occur at 51.4, 85.8, and 79.2 mbsf at Sites U1305, U1306, and U1307, respectively. Below the depths of delta (super 13) C (sub DIC) minima, delta (super 13) C (sub DIC) values generally increase toward the bottom of the cored interval.
