Computing marine-ice thickness at an ice-shelf base [PDF]

Journal of Glaciology, 2002
AbstractThe freezing of sea water to the base of an ice shelf can give rise to large patches of accumulated ice, a phenomenon known as marine ice. In this study a numerical method is presented for calculating the thickness of the marine-ice layer using an ice- shelf-ocean model.

Improving the spatial distribution of modeled Arctic sea ice thickness [PDF]

, 2005
The spatial distribution of ice thickness/draft in the Arctic Ocean is examined using a sea ice model. A comparison of model predictions with submarine observations of sea ice draft made during cruises between 1987 and 1997 reveals that the model has the

Ice sheet extent and early deglacial history of the southwestern sector of the Greenland ice sheet [PDF]

, 2009
The offshore and coastal geomorphology of southwest Greenland records evidence for the advance and decay of the Greenland Ice Sheet during the Last Glacial Maximum.

Influence of ice crystal shape on retrieval of cirrus optical thickness and effective radius: A case study [PDF]

, 2009
Airborne measurements of spectral upwelling radiances (350â  2200 nm) reflected by cirrus using the Spectral Modular Airborne Radiation measurement sysTem (SMART)-Albedometer were made over land and water surfaces.

Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]

, 2014
Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.

Evaluation of Operation IceBridge quick-look snow depth estimates on sea ice [PDF]

, 2015
We evaluate Operation IceBridge (OIB) ‘quick-look’ (QL) snow depth on sea ice retrievals using in situ measurements taken over immobile first-year ice (FYI) and multi-year ice (MYI) during March of 2014. Good agreement was found over undeformed FYI (-4.5

Reconstructing ice-sheet accumulation rates at ridge B, East Antarctica [PDF]

, 2004
Understanding how ice sheets responded to past climate change is fundamental to forecasting how they will respond in the future. Numerical models calculating the evolution of ice sheets depend upon accumulation data, which are principally available from ...

Antarctic sea ice thickness and snow-to-ice conversion from atmospheric reanalysis and passive microwave snow depth [PDF]

, 2008
Passive microwave snow depth, ice concentration, and ice motion estimates are combined with snowfall from the European Centre for Medium-Range Weather Forecasting (ECMWF) reanalysis (ERA-40) from 1979-2001 to estimate the prevalence of snow-to-ice ...

Proposal of a Method to Calculate Ice Thickness Variation Considering the Transition of Frazil into Ice [PDF]

, 2008
In this study, the behavior of ice plates and frazil were clarified by categorizing temporal changes based on the results of field observation conducted at the Shokotsu and Yubetsu rivers in Hokkaido.

Emergence of the Shackleton Range from beneath the Antarctic Ice Sheet due to glacial erosion [PDF]

, 2014
This paper explores the long-term evolution of a subglacial fjord landscape in the Shackleton Range, Antarctica. We propose that prolonged ice-sheet erosion across a passive continental margin caused troughs to deepen and lower the surrounding ice-sheet ...
