Sea-ice thickness and mass at Ice Station Belgica, Bellingshausen Sea, Antarctica
Deep Sea Research Part II: Topical Studies in Oceanography, 2011Abstract 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
2019Current 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 ...

Evolution of the thickness distribution of ice in the sea of Japan [PDF]
Izvestiya, Atmospheric and Oceanic Physics, 2006 Simple mathematical models of the thermodynamics of the ice-cover thickness and the thermodynamics of the area of an individual ice floe are proposed. The equations of the models allow for an explicit consideration of the spatial boundedness of the seawater region containing ice covers.

Digital Processing By Sea Ice Thickness Measuring
[Proceedings] IGARSS'91 Remote Sensing: Global Monitoring for Earth Management, 2005The present paper deals with digital processing aspects of real superbroadband subsurface radar signals using the inverse filtration method in the presence or absence of a priori information about the form or spectrum of sounding signal. It is proposed a new radar calibration method based on a statistical approach which comprises energy spectra ...

Sea ice thickness distribution in Fram Strait
Nature, 1983HM nuclear submarine Sovereign has obtained the first synoptic measurements of the ice thickness distribution in Fram Strait, the main outflow from the Arctic Ocean. The ice nearest the ice edge is of quite different character from ice in the interior of the Strait, with a greater proportion of first-year ice and less pressure ridging.

Thickness sensitivities in the CICE sea ice model
Ocean Modelling, 2010Abstract Passive microwave satellite observations of ice extent and concentration form the foundation of sea ice model evaluations, due to their wide spatial coverage and decades-long availability. Observations related to other model quantities are somewhat more limited but increasing as interest in high-latitude processes intensifies.

Modeling a Variable Thickness Sea Ice Cover
Monthly Weather Review, 1980A numerical model simulating a variable thickness sea ice cover over a seasonal cycle is presented. The model includes a fixed depth mixed-layer formulation with open water heat absorption and lateral melting terms, and a mechanical distribution function consistent with the physics of the ridging process.
