GRIP ice core detailed water isotope (δ18O) data

The ice core was drilled during the GRIP project in 1989-1992 at the Summit of the Greenland ice sheet. The length is 3025 m. Present-day accumulation 0.23 m ice/yr. Position...

High-resolution impurity data from the GRIP ice core

The ice core was drilled during the GRIP project in 1989-1992 at the Summit of the Greenland ice sheet. The length is 3025 m. Present-day accumulation 0.23 m ice/yr. Position...

DYE-3 4B ice core detailed water isotope data

The shallow core 4B was drilled to 174 m 8 km upstream from DYE-3 (DYE-3 main core position: 65.18N, 43.83W). The exact position is not available. The delta-18O data were all...

Ice core O2 clumped isotope data from the Last Glacial Maximum measured in Gr...

Laboratory O2 clumped-isotope data (as D36 values measured at Rice University) for air occluded in ice core GISP2-D spanning gas ages of 18000-21000 ky BP for the Last Glacial...

Clay mineralogy, Sr-Nd-Hf-H isotope data of NGRIP ice core dust and potential...

These three datasets contain the analytical results of clay mineralogy and 87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf and D/H (2H/1H) isotope measurements performed on last glacial...

Reconstructed volcanic stratospheric sulfur injections and volcanic sulfate d...

We used four polar ice cores - two from Greenland and two from Antarctica - to investigate volcanic sulphate deposition on polar ice sheets between 13,200 and 12,800 years BP....

Thermal conductivity of snow, antarctic firn and porous ice at -3°C, -20°C an...

This dataset presents values of effective thermal conductivity of 64 samples of snow, antarctic firn and porous ice in the x, y and z directions (z being the direction of...

Volcanic synchronization GISP2 versus NEEM(2011-S1) on the NS1-2011 timescale

The core depths for GISP2 and the NEEM(2011S1) ice cores for 92 common volcanic deposition events derived from volcanic synchronization of the GISP2 sulphate record against the...

Last Interglacial synthesis of high-latitude temperature: temperature anomali...

The Last Interglacial (LIG, 129-116 thousand of years BP, ka) represents a test bed for climate model feedbacks in warmer-than-present high latitude regions. However, mainly...

(Table 1) Micro-inclusion counts and ion concentrations in the five GRIP ice-...

We provide the first direct evidence that a number of water-soluble compounds, in particular calcium sulfate (CaSO4 2H2O) and calcium carbonate (CaCO3), are present as solid,...

(Data D1) Annual climate proxy data from the NGRIP ice core, Greenland

The last two abrupt warmings at the onset of our present warm interglacial period, interrupted by the Younger Dryas cooling event, were investigated at high temporal resolution...

(Table 1) Gas tie points used to correlate the ice cores NGRIP and EDML

Water isotope records from the EPICA Dronning Maud Land (EDML) and the NorthGRIP ice cores have revealed a one to one coupling between Antarctic Isotope Maxima (AIM) and...

Match points used for synchronization of NGRIP, GRIP, and GISP2

We here present a synchronization of the NGRIP, GRIP, and GISP2 ice cores based mainly on volcanic events over the period 14.9-32.45 ka b2k (before AD 2000), corresponding to...
