Skytrain Ice Rise ice core: age model ST22 and underlying data
We present an age model for the 651 m deep Skytrain Ice Rise ice core (79°44.5'S, 78°32.7'W). The top 2000 years have previously been dated using age markers interpolated... -
Age model output of ice core Skytrain Ice Rise
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... -
Non-sea-salt magnesium of ice core Skytrain Ice Rise
nssMg determined by inductively coupled plasma mass spectrometry (Agilent 7700x ICP-MS) on meltwater from a continuous flow melt device. -
Methane concentrations of ice core Skytrain Ice Rise
Continuous CH4 determined by cavity ringdown spectroscopy (Picarro G2301 CRDS) on air separated from meltwater from a continuous flow melt device. -
A new helium isotope recored of the Paleocene-Eocene Thermal Maximum from ODP...
The Paleocene-Eocene Thermal Maximum (PETM; around 56 Ma ago) is arguably the most intensively studied event of rapid greenhouse warming of the geological past. The duration and... -

Bayesian age-depth modelling applied to varve counting and radiometric dating...
Four different age-depth models have been calculated for a new sediment profile (HZM19) from Holzmaar (425 m a.s.l., 50°7'8'' N, 6°52' 45'' E) using Bayesian statistics with... -
Lead-210 measurements of the composite profile HZM19
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... -
Cs-137 activity of the composite profile HZM19
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... -
Bayesian Modelling of the composite profile HZM19
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... -
Varve chronology of the composite profile HZM19
Based on 43 predefined marker layers and 41 radiocarbon sampling positions with their specific VT-99 age and error, then lineary interpolated. Technical gap from 10859 to 10989 mm.
