ICESat measurements of sea ice freeboard and estimates of sea ice thickness in the Weddell Sea [PDF]
Journal of Geophysical Research: Oceans, 2008 Sea ice freeboard heights in the Weddell Sea of Antarctica are derived from the Ice, Cloud, and Land Elevation Satellite (ICESat) laser altimeter measurements, which have a unique range precision to flat surfaces of 2 cm within 70 m footprints spaced at 172 m along track. Although elevations of flat surfaces can be obtained to an accuracy of ∼10 cm (1σ)

Evaluation of sea-ice thickness from four reanalyses in the Antarctic Weddell Sea [PDF]
The Cryosphere, 2021 Ocean–sea-ice coupled models constrained by various observations provide different ice thickness estimates in the Antarctic. We evaluate contemporary monthly ice thickness from four reanalyses in the Weddell Sea: the German contribution of the project ...

Assessment of contemporary satellite sea ice thickness products for Arctic sea ice [PDF]
The Cryosphere, 2018 Abstract. Advances in remote sensing of sea ice over the past two decades have resulted in a wide variety of satellite-derived sea ice thickness data products becoming publicly available. Selecting the most appropriate product is challenging given end user objectives range from incorporating satellite-derived thickness information in operational ...

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.

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.

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.

Impact assessment of snow thickness, sea ice density and water density in CryoSat-2-derived sea ice thickness [PDF]
The CryosphereSea ice thickness is an essential climate variable, which is often derived from satellite altimetry freeboard estimates, e.g., by CryoSat-2. In order to convert freeboard to sea ice thickness, assumptions are needed for snow thickness, snow density, sea ...
