Bulk sediment records from ODP Site 851, eastern equatorial Pacific Ocean

Daniele Reghellin, Gerald R. Dickens, Helen K. Coxall, Jan Backman

The data comprise coarse fraction concentrations, carbonate content and carbon and oxygen stable isotopes (δ¹³C and δ¹⁸O) of deep-sea sediment samples from the Ocean Drilling Program (ODP) Site 851 located in the eastern equatorial Pacific Ocean.

The data were generated to better understand the origin and the paleoceanographic meaning of bulk marine sediment stable isotope records. These data are useful indicators of past surface water conditions, including temperature and intensity of biological production.

The data were collected during the ODP Leg 138 in 1991. The sediment samples have an age comprised between 0.00 and 6.79 million years ago.

Data description

The dataset comprises four data tables recording coarse fraction concentrations, carbonate content and carbon and oxygen stable isotopes (δ¹³C and δ¹⁸O) of deep-sea sediment samples. Each data table is provided both as xlsx and semicolon separated value (csv) files. A figure including the age-depth model for the samples is also included.

Comments

Site 851 was drilled at 2°24.2’ N latitude, at 110°34.3’ W longitude, and at a water depth of 3760 m.
