Impacts of Sea Ice Thickness Initialization on Seasonal Arctic Sea Ice Predictions
A promising means for increasing skill of seasonal predictions of Arctic sea ice is improving sea ice thickness (SIT) initial conditions; however, sparse SIT observations limit this potential.

Sea Ice Thickness in the Western Ross Sea [PDF]
Using 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 ...

Impact assessment of snow thickness, sea ice density and water density in CryoSat-2-derived sea ice thickness [PDF]
Sea 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 ...

Sea ice thickness and recent Arctic warming [PDF]
The climatic impact of increased Arctic sea ice loss has received growing attention in the last years. However, little focus has been set on the role of sea ice thickness, although it strongly determines surface heat fluxes. Here ensembles of simulations

The sub-ice platelet layer and its influence on freeboard to thickness conversion of Antarctic sea ice [PDF]
This is an investigation to quantify the influence of the sub-ice platelet layer on satellite measurements of total freeboard and their conversion to thickness of Antarctic sea ice. The sub-ice platelet layer forms as a result of the seaward advection of

Near-real-time Arctic sea ice thickness and volume from CryoSat-2 [PDF]
Timely observations of sea ice thickness help us to understand the Arctic climate, and have the potential to support seasonal forecasts and operational activities in the polar regions.

Summertime sea-ice prediction in the Weddell Sea improved by sea-ice thickness initialization. [PDF]
AbstractSkillful sea-ice prediction in the Antarctic Ocean remains a big challenge due to paucity of sea-ice observations and insufficient representation of sea-ice processes in climate models. Using a coupled general circulation model, this study demonstrates skillful prediction of the summertime sea-ice concentration (SIC) in the Weddell Sea with ...

Sea ice thickness as a stochastic process [PDF]
Observed probability distributions of sea ice thickness are approximately exponential for thick ice. An explanation is given on the basis of simple representations of the thermal and mechanical processes. The argument predicts that the eāfolding scale for the exponential is proportional to the thermal equilibrium thickness.

Recent summer sea ice thickness surveys in Fram Strait and associated ice volume fluxes [PDF]
Fram Strait is the main gateway for sea ice export out of the Arctic Ocean, and therefore observations there give insight into the composition and properties of Arctic sea ice in general and how it varies over time.
