Temperature profile of different summer sea-ice cores collected in the Eurasian basin during CAATEX 2019 cruise

, 2023
The physical properties of sea ice, including salinity, sea ice temperature, and sea ice texture as well as isotopic composition (oxygen and hydrogen) were analyzed from samples collected on the CAATEX 2019 expedition to the central Arctic Ocean (between

Physically Based Summer Temperature Reconstruction From Melt Layers in Ice Cores

Earth and Space Science, 2021
Previous reconstructions of summer temperatures from ice cores have relied on a statistical relationship between a melt layer and temperature observed at nearby stations. This study presents a novel method for reconstructing summer temperatures from melt

Variety and Distribution of Diatom-Based Sea Ice Proxies in Antarctic Marine Sediments of the Past 2000 Years

Geosciences, 2022
Antarctic sea ice is an essential component of the global climate system. Reconstructions of Antarctic sea ice from marine sediment cores are a vital resource to improve the representation of Antarctic sea ice in climate models and to better understand ...

Chlorine 36 fallout in the Summit Greenland Ice Core Project ice core [PDF]

Journal of Geophysical Research: Oceans, 1997
The natural cosmogenic radioisotope 36Cl has been measured in the Greenland Ice Core Project ice core from Summit, Greenland. Generally, a good correlation between 36Cl and δ18O was found, even in glacial periods with strong δ18O oscillations. The 36Cl flux is calculated assuming an exponential relationship between accumulation rate and δ18O.

Decadal-interdecadal climate variability over Antarctica and linkages to the Tropics : analysis of ice core, instrumental, and tropical proxy data [PDF]

, 2012
The Antarctic continent contains the majority of the global ice volume and plays an important role in a changing climate. The nature and causes of Antarctic climate variability are, however, poorly understood beyond interannual time scales due to the ...

An improved north–south synchronization of ice core records around the 41 kyr ¹⁰Be peak [PDF]

Climate of the Past, 2017
Using new high-resolution 10Be measurements in the NGRIP, EDML and Vostok ice cores, together with previously published data from EDC, we present an improved synchronization between Greenland and Antarctic ice cores during the Laschamp geomagnetic ...

Beryllium 10 in the Greenland Ice Core Project ice core at Summit, Greenland [PDF]

Journal of Geophysical Research: Oceans, 1997
Concentrations of the cosmogenic isotope 10Be have been measured in more than 1350 samples from the Greenland Ice Core Project (GRIP) ice core drilled at Summit, Greenland. Although a dust‐associated component of 10Be retained by 0.45 μm filters in some of the samples complicates the interpretations, the results confirm that the first‐order origin of ...

Three-dimensional multitrack electrical conductivity method for interpretation of complex ice core stratigraphy

Journal of Glaciology
Recent ice cores from the Allan Hills, a blue ice area in Antarctica, are nearly 3 million years old. These cores extend ice core chronologies, enabling new insight into key climate periods such as the Mid-Pleistocene Transition.
