In this dataset we include C and N elemental and isotopic (TOC, TN, CaCO3, d 13 C-TOC, d 15 N-TN), biogenic silica, X-ray fluorescence, grain size, physical property core logs, benthic foraminifer isotopes, planktic foraminifer radiocarbon, and mass accumulation rate data from India National Gas Hydrate Program Expedition 01 Hole 19B. Hole 19B is located in the Mahanadi Basin ~70 km off the eastern Indian Margin in 1422 m water depth (18° 58.65680' N, 85° 39.52020' E). These data are from the upper 12 m below seafloor, corresponding to the last 110 kyr. Details of these analyses are published in Phillips, S.C . , Johnson, J.E., Giosan, L., and Rose, K., 2014.
