We used a 2.5D inverse model constrained by radar horizons to find the age-depth profile at the European Beyond EPICA - Oldest Ice project drill site (BELDC; 75.29917 °S,...

This dataset provides age-depth relationships and age models for sites at the Peru continental margin, based on various radiometric, biostratigraphic and lithostratigraphic...

Conducted using Bacon (version 4.1.1) for the R programming software. Model A: based on C-14 only; Model B: based on radiocarbon, parameter settings derived from information of...

31 samples were sampled with a thickness of 2 cm. Activity of total Pb-210 was determined indirectly by measuring Po-210 using alpha spectrometry. Activities were measured using...

47 samples were sampled with a thickness of 2 cm. The activity of Cs-137 was determined directly by gamma-ray spectrometry from freeze-dried and homogenized samples. Gamma...

nssMg determined by inductively coupled plasma mass spectrometry (Agilent 7700x ICP-MS) on meltwater from a continuous flow melt device.

Age model derived using Paleochrono program using fixed tiepoints described in the paper. Our recommended ice age scale uses ALC age until 1337 a bp and Paleochrono for all...

Continuous CH4 determined by cavity ringdown spectroscopy (Picarro G2301 CRDS) on air separated from meltwater from a continuous flow melt device.
