Ice sheet model dependency of the simulated Greenland Ice Sheet in the mid-Pliocene [PDF]

Climate of the Past, 2015
Abstract. The understanding of the nature and behavior of ice sheets in past warm periods is important for constraining the potential impacts of future climate change. The Pliocene warm period (between 3.264 and 3.025 Ma) saw global temperatures similar to those projected for future climates; nevertheless, Pliocene ice locations and extents are still ...

Numerical estimation of 10000 years later equilibrium ice sheet profile in the Shirase Glacier drainage basin, East Antarctica

Antarctic Record, 1991
Recent observations show that the ice sheet in the Shirase Glacier drainage basin, East Antarctica, is thinning. If the observed thinning is assumed to be a transitional process in which the ice sheet is adjusting to the present climate, an equilibrium ...

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 ...

Quantitative sub-ice and marine tracing of Antarctic sediment provenance (TASP v1.0) [PDF]

Geoscientific Model Development
Ice sheet models should be able to accurately simulate palaeo ice sheets to have confidence in their projections of future polar ice sheet mass loss and resulting global sea level rise.

Antarctic ice sheet thickness estimation using the horizontal-to-vertical spectral ratio method with single-station seismic ambient noise [PDF]

The Cryosphere, 2018
We report on a successful application of the horizontal-to-vertical spectral ratio (H / V) method, generally used to investigate the subsurface velocity structures of the shallow crust, to estimate the Antarctic ice sheet thickness for the first time.

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

Molecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...

A theoretical steady state profile of ice sheets (two-dimentional model)

Antarctic Record, 1977
The Nye's kinematic theory of ice sheet profiles is revised on the basis of the conservation law of ice mass, because the Nye's ice sheet model or the revised Haefeli's model does not satisfy the ice mass conservation law and therefore they cannot have a

Antarctic bedrock topography uncertainty and ice sheet stability [PDF]

, 2015
All Rights Reserved. Antarctic bedrock elevation estimates have uncertainties exceeding 1km in certain regions. Bedrock elevation, particularly where the bedrock is below sea level and bordering the ocean, can have a large impact on ice sheet stability ...

Ice-Sheet Dynamics

Annual Review of Fluid Mechanics, 2013
We describe the development of mathematical models of ice sheets, focusing on underlying physics and the minimal components that successful models must contain. Our review describes the basic fluid dynamical ice-flow models currently in use; points out numerous poorly understood thermomechanical feedbacks in ice flow; and describes the current, often ...

Characterization of the thermophilic xylanase Fsa02490Xyn from the hyperthermophile Fervidibacter sacchari belonging to glycoside hydrolase family 10

FEBS Open Bio, EarlyView.
Fervidibacter sacchari is a member of the bacterial phylum Armatimonadota, only a few of which have been cultivated. It is a hyperthermophilic polysaccharide degradation specialist. We show that a secreted enzyme, Fsa02490Xyn, is an endoxylanase belonging to glycoside hydrolase family 10.
