The thickness variable in sea‐ice models

Atmosphere-Ocean, 1998
Abstract The thickness distribution function is considered a fundamental state variable for sea‐ice. However, certain assumptions are implicit in its use. Based largely on observations, we estimate upper and lower bounds on the spatial scale for which the usual interpretation of the thickness distrbituion function is valid. These scales turn out to be ∼

Sea-ice thickness and mass at Ice Station Belgica, Bellingshausen Sea, Antarctica

Deep Sea Research Part II: Topical Studies in Oceanography, 2011
Abstract Ice Station Belgica was commenced in late winter 2007 in the Bellingshausen Sea as part of Sea Ice Mass Balance in Antarctica (SIMBA), an IPY 2007 cruise on the research vessel N.B. Palmer. A primary objective was to build on the work of previous Antarctic drift station experiments to geophysically characterize sea ice in terms of thickness,

Arctic sea ice extent and thickness

Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1995
Abstract Current knowledge on Arctic sea ice extent and thickness variability is reviewed, and we examine whether measurements to date provide evidence for the impact of climate change. The total Arctic ice extent has shown a small but significant reduction of (2.1 ± 0.9)% during the period 1978-87, after apparently increasing from a ...

Improving sea-ice cover and SST forecasts by sea-ice thickness initialization

2020
<p>A substantial amount of subseasonal-to-seasonal sea-ice variability is potentially predictable, but improved model biases and initialization techniques are needed to realize this potential. Forecasts for other Earth System components can be expected to benefit from improved sea-ice forecasts as well, because the presence of ...

Towards Improved Mapping of Sea Ice Concentration and Sea Ice Thickness with SWOT

Observing sea ice concentration (SIC) and thickness (SIT) remains a key challenge for climate monitoring and modeling. Satellite altimetry provides measurements of ice and sea level anomaly from which can be estimated SIC, sea ice freeboard, and ultimately SIT.

Airborne Measurement of Snow Thickness over Sea Ice

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Snow cover on sea ice plays an important role in the climate of the polar regions. Snow on the sea ice reduces the heat exchange between the ocean and the atmosphere by its high albedo and low thermal conductivity. The lower the albedo, the less solar energy is reflected back into the atmosphere. Data on the extent and thickness of snow cover is needed
