Reconstructed biogenic opal percentage and accumulation for site J1007, Chile...

Sediment cores at sites J1007 were collected from the Chilean Margin during D/V JOIDES Resolution Expedition 379T (JR100) in 2019. Sedimentary Green/Blue (G/B) ratio data were...

Atlantic 231Pa/230Th and biogenic opal compilation of the Holocene and the LGM

The strength and geometry of the Atlantic meridional overturning circulation is tightly coupled to climate on glacial-interglacial and millennial timescales, but has proved...

Mass fluxes and elemental composition of particulate export in KOSMOS mesocos...

The present dataset contains measurements of vertical particle fluxes (export) and their elemental composition. Data was collected with sediment traps in several in situ...

Si/Al derived opal concentrations of IODP Site U1537

We calculated the opal content by normalizing XRF based Si/Al-ratios with FTIRS based biogenic opal measurements. This shows a much stronger correlation (R=0.96) for the last...

Bulk sedimentary δ¹⁵N records of sediment cores 363-U1486, MD05-2920, MD01-23...

Bulk sedimentary δ¹⁵N records of MD06-3067, MD98-2181, MD98-2177, MD97-2138, MD05-2920, and MD98-2162 and calculated northern and southern hemisphere stack records: Along with...

FTIRS-based opal data of IODP Site U1537

This data is complementing the dataset from Weber et al. 2022.We used Fourier Transform Infrared Spectroscopy (FTIRS) to quantify biogenic opal to obtain information on past...

XRF based barium and aluminium calibrated by punctual solution based ICP-OES ...

Bulk element concentrations were measured for a subset of samples on aliquots after digestion on an ICP-OES (Agilent 700 Series) at the Institute of Earth Sciences, Heidelberg...

Bulk sediment element concentrations and biogenic barium of IODP Site U1537

Bulk element concentrations were measured for a subset of samples on aliquots after digestion on an ICP-OES (Agilent 700 Series) at the Institute of Earth Sciences, Heidelberg...

Porewater uranium concentrations of IODP Site U1537

Measurements were performed on an ICP-MS (Agilent 7500 Series) at the GEOMAR Helmholtz Centre for Ocean Research Kiel.

Bulk sediment U and Th isotope data, δ234U, authigenic Uranium (aU) and 230Th...

Isotopic measurements were conducted on a triple quadrupole ICP-MS (iCAP TQe ICP-MS ThermoFisher Scientific) coupled with an Apex IR (ESI) at the Institute of Earth Sciences,...

Content of organic and inorganic carbon, nitrogen and opal for IODP Hole 344-...

The total weight percent of sedimentary carbon (% C) and nitrogen (% N), as well as inorganic carbon (% Cinorg) and organic carbon (% Corg) were measured using a macro elemental...

Opal mass accumulation rates from IODP Site 361-U1475

Biogenic silica accumulation was obtained by analyzing approximately 200 mg of homogenized and freeze dried sediment for each sample. Cleaning, chemical treatment, and...

Abundance of Neogloboquadrina pachyderma sinistral from IODP Site 361-U1475

Neogloboquadrina pachyderma abundance was obtained by washing ~ 10 cm³ of sediment through a 150µm sieve and drying at ~ 50 ºC for 24 h. This dried fraction was split until a...

δ¹⁵N in planktonic foraminifera species Globigerina bulloides and Globorotali...

Individual species were identified and ~550 individuals per species were picked from the >250 µm fraction under dissecting microscope for each sample. Approximately 7 mg of...
