Summary: | Progress Code: completed Statement: An empty tin cup was run at the beginning of the analysis and the obtained blank was then subtracted from all subsequent samples. Sulfanilamide EA standards containing a known amount of carbon and nitrogen were run every 6th sample and used for instrument drift and elemental quantification. This method provides quantitative data on element content in the samples, generally achieving a precision of 0.1% for C and N concentrations. Purpose These data were collected to determine the stable isotope composition and organic carbon concentration of marine sediment. Sediment cores were collected from the East Antarctic margin, aboard the Australian Marine National Facility R/V Investigator from January 14th to March 5th 2017 (IN2017_V01; (Armand et al., 2018). This marine geoscience expedition, named the “Sabrina Sea Floor Survey”, focused notably on studying the interactions of the Totten Glacier with the Southern Ocean through multiple glacial cycles. The cores were collected using a multi-corer (MC) and a Kasten corer (KC). The MC were sliced every centimetre, wrapped up in plastic bags, and stored in the fridge. The KC was sub-sampled using a u-channel; and sliced every centimetre once back the home laboratory (IMAS, UTAS, Hobart, Australia). This dataset presents stable isotopes measured in total and fumigated (i.e. organic) sediment samples collected during the IN2017_V01 voyage. The data include the sampling date (day/month/year), the latitude and longitude (in decimal degrees), the seafloor depth (in meter), the sediment core ID, the sediment depth (in cm), the elemental concentration (in %) and the stable isotope (13C, 15N and 34S) compositions reported as delta values (in ‰).
