Attribute Value
Methodology
  • The bulk sedimentary d15N was measured on unacidified samples with isotope ratio mass spectrometer (IRMS). Total organic carbon (TOC) and total nitrogen (TN) were measured on acidified samples on the elemental analyzer.
Description
  • The dataset contains bulk sedimentary d15N, TOC, and TN data measured every 2 mm on the core SPR0901-03KC. Flood and turbidite layers are shaded with blue and orange in the files.

  • This work is supported by NSF OCE-1304327.

Overview: This dataset includes bulk sedimentary d15N, total organic carbon (TOC), and total nitrogen (TN),

Methods: The bulk sedimentary d15N was measured on unacidified samples with isotope ratio mass spectrometer (IRMS). Total organic carbon (TOC) and total nitrogen (TN) were measured on acidified samples on the elemental analyzer.

Files contained:
'Supplemental_Table_1_TOC_TN_03KC.xlsx': TOC and TN data
'Supplemental_Table_2_d15N_03KC.xlsx': d15N data

Variables in 'Supplemental_Table_1_TOC_TN_03KC.xlsx':

Age(CE): Age (calendar year) for each sample. The age model was generated based on mixed planktonic foraminifera 14C measurements using Bacon 2.2 software (see Du et al. (2018), Marine Geology, doi: 10.1016/j.margeo.2017.11.014). Negative values refer to BCE and decimal places in the age data are kept as they were when generated from the software;
TN (%): Total nitrogen of the acidified samples (unit: wt.%);
TOC (%): Total organic carbon of the acidified samples (unit: wt.%);
Molar C/N: Molar ratio of carbon/nitrogen in the acidified samples;
TOC(%) after removing flood and turbidite: TOC data after removing flood and turbidite layers in the core (shaded in blue and orange, respectively) that were identified from core fabric changes and low TOC content.

d15N after removing flood and turbidite (‰): d15N data after removing flood and turbidite layers in the core (shaded in blue and orange, respectively) that were identified from core fabric changes and low d15N.
