On the occurrence of annual layers in Dome Fuji ice core early Holocene ice [PDF]

Climate of the Past, 2015
Whereas ice cores from high-accumulation sites in coastal Antarctica clearly demonstrate annual layering, it is debated whether a seasonal signal is also preserved in ice cores from lower-accumulation sites further inland and particularly on the East ...

An initial intercomparison of atmospheric and oceanic climatology for the ICE-5G and ICE-4G models of LGM paleotopography [PDF]

, 2005
This paper investigates the impact of the new ICE-5G paleotopography dataset for Last Glacial Maximum (LGM) conditions on a coupled model simulation of the thermal and dynamical state of the glacial atmosphere and on both land surface and sea surface ...

How does sea ice influence δ¹⁸O of Arctic precipitation? [PDF]

Atmospheric Chemistry and Physics, 2017
This study investigates how variations in Arctic sea ice and sea surface conditions influence δ18O of present-day Arctic precipitation. This is done using the model isoCAM3, an isotope-equipped version of the National Center for Atmospheric Research ...

Evolution of Pliocene climate cyclicity at Hole 806B (5-2 Ma); oxygen isotope record [PDF]

, 1993
A detailed Pliocene oxygen isotope record from the Ontong Java Plateau, based on measurements of the surface-dwelling planktonic foraminifer Globigerinoides sacculifer, was produced for the period from 5 to 2 Ma. The record documents major long and short-

Greenland ice core “signal” characteristics: An expanded view of climate change [PDF]

, 1993
The last millenium of Earth history is of particular interest because it documents the environmental complexities of both natural variability and anthropogenic activity. We have analyzed the major ions contained in the Greenland Ice Sheet Project 2 (GISP

Response of the large-scale subglacial drainage system of Northeast Greenland to surface elevation changes [PDF]

The Cryosphere, 2015
The influence of subglacial water on the dynamics of ice flow has been the object of increasing interest in the past decade. In this study we focus on large-scale, long-term changes in surface elevation over Northeast Greenland and the corresponding ...

Towards high resolution, validated and open global wind power assessments

Nature Communications
Wind power is widely recognized as a key component of future net-zero energy systems. However, substantial variability among current wind resource and power simulations used for wind farm deployment limits the reliability of siting and system integration

East Greenland ice core dust record reveals timing of Greenland ice sheet advance and retreat

Nature Communications, 2019
Accurate measurements of the past extent of the Greenland ice sheet are crucial to understand its response to changing climate conditions. Here, the authors present a dust record from an ice core from the east coast of Greenland to provide detailed time ...

Influence of temperature fluctuations on equilibrium
ice sheet volume [PDF]

The Cryosphere, 2018
Forecasting the future sea level relies on accurate modeling of the response of the Greenland and Antarctic ice sheets to changing temperatures. The surface mass balance (SMB) of the Greenland Ice Sheet (GrIS) has a nonlinear response to warming. Cold

A new regional climate model for POLAR-CORDEX : evaluation of a 30-year hindcast with COSMO-CLM2 over Antarctica [PDF]

, 2019
Continent-wide climate information over the Antarctic Ice Sheet (AIS) is important to obtain accurate information of present climate and reduce uncertainties of the ice sheet mass balance response and resulting global sea level rise to future climate ...
