Mapping technique of climate fields between GCM's and ice models
technique climate fields GCM's ice models
<
2010/2/5
Here, we present a mapping method OBLIMAP, which projects and interpolates fields like surface temperature, surface mass balance, and surface height between a geographical based coordinate system of a...
Interaction between ice sheet dynamics and subglacial lake circulation:a coupled modelling approach
ice sheet dynamics subglacial lake circulation coupled modelling approach
<
2010/2/3
Subglacial lakes in Antarctica influence to a large extent the flow of the ice sheet. In this study we use an idealised lake geometry to study this impact. We employ a) an improved three-dimensional f...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data
basal properties ice streams surface measurements non-linear Bayesian inverse approach
<
2010/2/4
We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We dem...
Palaeomagnetic Results from the Sarmatian/Pannonian Boundary in North-Eastern Croatia (Vranovi Section,Našice Quarry)
Palaeomagnetism Palynology Sarmatian Pannonian Central Paratethys Croatia
<
2009/12/8
The Sarmatian/Pannonian boundary in the Central Paratethys basin is marked by a major regressive event, which isolated the basin from the open sea and resulted in a palaeoenvironmental change from res...
Weichselian interstadial sediments on Jæren (SW Norway)–paleoenvironments and implications for ice sheet configuration
Weichselian interstadial sediments paleoenvironments implications ice sheet configuration
<
2009/12/3
Interstadial glaciomarine sediments at Jæren in south-western Norway have been investigated for their composition, distribution and age, and a model for the depositional environment is proposed....
Mapping glaciers in Jotunheimen,South-Norway,during the Little Ice Age maximum

<
2010/2/4
The maximum glacier extent during the "Little Ice Age" (mid 18th century AD) in Jotunheimen, southern Norway, was mapped using remote sensing techniques. Interpretation of existing glaciochronological...
Diagnostic and prognostic simulations with a full Stokes model accounting for superimposed ice of Midtre Lovénbreen,Svalbard
Diagnostic and prognostic simulations full Stokes model superimposed
<
2010/2/4
We present steady state (diagnostic) and transient (prognostic) simulations of Midtre Lovénbreen, Svalbard performed with the thermo-mechanically coupled full-Stokes code Elmer. This glacier has an ex...
Non-Gaussian Bayesian retrieval of tropical upper tropospheric cloud ice and water vapour from Odin-SMR measurements
Non-Gaussian Bayesian retrieval tropical upper tropospheric cloud ice water vapour
<
2010/2/8
Improved Odin-SMR retrievals of upper tropospheric water are presented. The new retrieval algorithm retrieves humidity and cloud ice mass simultaneously and takes into account of cloud inhomogeneities...
Environmental records from temperate glacier ice on Nevado Coropuna saddle, southern Peru

2010/1/28
We investigated past climate variability and the zonal short and long-range transport of air masses in tropical South America using chemical, isotopic and palynological signals from a 42 m-long ice co...

2009/12/10
Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace ...
Layer disturbances and the radio-echo free zone in ice sheets
Layer disturbances radio-echo free zone ice sheets
<
2010/2/3
Radio-echo sounding of the Antarctic and Greenlandic ice sheets often reveals a layer in the lowest hundreds of meters above bedrock more or less free of radio echoes, known as the echo-free zone (EFZ...

2010/2/8
During several periods since 2005 the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on Envisat has performed observations dedicated to the region of the upper troposphere/lower str...
Frost flower chemical signature in winter snow on Vestfonna ice cap,Nordaustlandet,Svalbard
Frost flower chemical signature winter snow Vestfonna ice cap
<
2010/2/3
The chemistry of snow and ice cores from Svalbard is influenced by variations in local sea ice margin and distance to open water. Snow pits sampled at two summits of Vestfonna ice cap (Nordaustlandet,...
