Arctic sea ice extent and thickness

Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1995
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 lower level in the early ...

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,

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 Profiling And Under-Ice Oil Entrapment

Offshore Technology Conference, 1977
ABSTRACT Results obtained with a unique dual-antenna impulse radar system used to profile first- and multi-year sea ice near Prudhoe Bay, Alaska, are discussed. A description of the radar system is given along with representative field data.

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.
