Arctic sea ice thickness and volume declining [PDF]

Eos, Transactions American Geophysical Union, 2013
The record low extent of Arctic sea ice area in September 2012 made headlines. Studies using models have suggested that sea volume has also been declining. A new study by Laxon et al. confirms this with observational data. The authors used satellite radar observations from the European Space Agency CryoSat‐2 mission to estimate Arctic sea ice thickness

Probabilistic Forecasts of Arctic Sea Ice Thickness [PDF]

Journal of Agricultural, Biological and Environmental Statistics, 2021
AbstractIn recent decades, warming temperatures have caused sharp reductions in the volume of sea ice in the Arctic Ocean. Predicting changes in Arctic sea ice thickness is vital in a changing Arctic for making decisions about shipping and resource management in the region.

Sea Ice Thickness in the Western Ross Sea [PDF]

Geophysical Research Letters, 2021
AbstractUsing airborne measurements, we provide a first direct glimpse of the sea ice thickness distribution in the western Ross Sea, Antarctica, where the distinguishing sea ice process is the regular occurrence of the Ross Sea, McMurdo Sound, and Terra Nova Bay polynyas.

Modeled Trends in Antarctic Sea Ice Thickness [PDF]

Journal of Climate, 2014
Abstract Unlike the rapid sea ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic ice thickness, and hence ice volume, do not currently exist.

Monitoring Sea Ice Thickness Using GNSS-Interferometric Reflectometry

IEEE Geoscience and Remote Sensing Letters, 2022
Abstract This letter presents the analysis of frozen sea surface properties using low-cost and low-complexity terrestrial global navigation satellite system (GNSS) receivers. Monitoring sea ice thickness and the mean sea level (MSL) of the frozen sea are performed using the interference frequency obtained by the GNSS interference pattern (IP) technique.

Sea-ice thickness variability in Storfjorden, Svalbard [PDF]

Annals of Glaciology, 2011
AbstractResults from electromagnetic induction surveys of sea-ice thickness in Storfjorden, Svalbard, reveal large interannual ice-thickness variations in a region which is typically characterized by a reoccurring polynya. the surveys were performed in March 2003, May 2006 and March 2007 with helicopter- and ship-based sensors.

Tracer Measurements in Growing Sea Ice Support Convective Gravity Drainage Parameterizations [PDF]

, 2020
Gravity drainage is the dominant process redistributing solutes in growing sea ice. Modeling gravity drainage is therefore necessary to predict physical and biogeochemical variables in sea ice.

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

Assimilation of sea-ice concentration in a global climate model — physical and statistical aspects [PDF]

, 2012
We investigate the initialisation of Northern Hemisphere sea ice in the global climate model ECHAM5/MPI-OM by assimilating sea-ice concentration data. The analysis updates for concentration are given by Newtonian relaxation, and we discuss different ways
