Stable carbon isotopes and total organic carbon of sediment core NBP20-02 KC7...

Stable carbon isotopic composition (δ13C) and Total Organic Carbon (TOC) content of the bulk sediments in core NBP20-02 KC72 were measured at 10-cm depth resolution at the...

Magnetic susceptibility measurements of sediment core NBP20-02 KC72 from Cran...

Magnetic susceptibility (MS) measurements along the archive tray were conducted three times at 1-cm spacing using a Bartington MS2C loop sensor at the Marine and Geology...

Grain size analysis of sediment core NBP20-02 KC72 from Cranton Bay, West Ant...

Grain size was analyzed at 10 cm intervals throughout core NBP20-02 KC72, with each sample spanning a 2 cm interval. Samples were analyzed with a Bettersizer S3 laser particle...

Diatom counts of sediment core NBP20-02 KC72 from Cranton Bay, West Antarctica

Samples were settled using the settling method of Scherer (1994) and Warnock and Scherer (2015). Diatoms were counted at 1000x magnification using an oil immersion objective...

Diatom-based age pointers for sediment core PS58/266-3

This dataset contains the age tie points for core PS58/266-3 derived from diatom-based stratigraphy.

Compiled Late Pliocene Stable Carbon Isotope Data from Sites in the Atlantic ...

Here we compiled stable carbon isotope data from 23 ODP sites in the Atlantic and Pacific, binned by marine isotope stage.Stable carbon isotope data were binned and averaged...

Diatom distribution in sediment core PG2208

A total of 37 samples from sediment core PG2208 were analyses for diatoms, of which we found valves in 32 samples. For species analysis we prepared diatom slides for light...

Mineral composition of sediment core PG2208

To analyze the mineralogical composition of sediments we freeze-dried and milled 19 samples for X-ray diffractometry (XRD) using a PHILIPS PW1820 goniometer (40 kV, 40 mA, from...

Grain size composition of sediment core PG2208

Before conducting grain-size analysis, we treated 36 samples with hydrogen peroxide (30%), set on a platform shaker for 4–5 weeks to remove organic matter, while keeping the pH...

Elemental composition of sediment core PG2208

Core sections were opened alongside and cut into halves of which one was used for non-destructive XRF scanning and back-up material, while the other one was subsampled for...

Age determination of sediment core PG2208

To gain a composite core record for core PG2208 (Figure 1) we used XRF data, i.e., Sr, to correlate overlapping parts of retrieved sections resulting in 367 cm in total. For...

Organic geochemistry of sediment core PG2208

To gain information on organic matter variability we analyzed 204 samples for total carbon (TC) and nitrogen (N), 190 samples for total organic carbon (TOC), 45 samples for...

Silicon isotopes in piston sediment core Lake850-Core3-1999 from Lake 850, Sw...

Data on core from Lake 850 sampled in 1999, including depth, ¹⁴C based age-depth model, loss-of-ignition and stable Si isotopes measured on diatom opal-A using Apex HF...

Biogenic silica, lithology and elemental composition of piston sediment core ...

Dataset includes depth and ¹⁴C based age-depth model of core from Lake 850 taken in March 2019. Biogenic silica, density, total organic carbon (TOC), total nitrogen content (%N)...
