Uncertainties in modelling CH4 emissions from northern wetlands in glacial climates：effect of hydrological model and CH4 model structure
northern wetlands glacial climates hydrological model CH4 model structure
2009/12/3
Methane (CH4) fluxes from northern wetlands may have influenced atmospheric CH4 concentrations at climate warming phases during the last 800 000 years and during the present global warming. Including ...
1-D-ice flow modelling at EPICA Dome C and Dome Fuji, East Antarctica
EPICA Dome C Dome Fuji East Antarctica
2008/11/6
One-dimensional (1-D) ice flow models are used to construct the age scales at the Dome C and Dome Fuji drilling sites (East Antarctica). The poorly constrained glaciological parameters at each site ar...
Climatic Conditions for modelling the Northern Hemisphere ice sheets throughout the ice age cycle
Northern Hemisphere ice sheet ice age cycle
2008/11/5
The ice sheet-climate interaction as well as the climatic response to orbital parameters and atmospheric CO2 concentration are examined in order to drive an ice sheet model throughout an ice age cycle...
Application of sediment core modelling to interpreting the glacial-interglacial record of Southern Ocean silica cycling
sediment core glacial-interglacial Southern Ocean silica cycling
2008/11/5
Sediments from the Southern Ocean reveal a meridional divide in biogeochemical cycling response to the glacial-interglacial cycles of the late Neogene. South of the present-day position of the Antarct...
Modelling the Early Weichselian Eurasian Ice Sheets: role of ice shelves and influence of ice-dammed lakes
Eurasian Ice Sheets ice shelves ice-dammed lake
2008/11/5
During the last glaciation, a marine ice sheet repeatedly appeared in Eurasia. The floating part of this ice sheet was essential to its rapid extension over the seas. During the earliest stage (90 kyr...
Change in ice rheology during climate variations – implications for ice flow modelling and dating of the EPICA Dome C core
ice rheology ice flow EPICA Dome C core
2008/11/4
The study of the distribution of crystallographic orientations (i.e., the fabric) along ice cores provides information on past and current ice flow in ice-sheets. Besides the usually observed formatio...
