"... Abstract: Sea ice covers wide area in Terra Nova Bay in East Antarctica where the Jangbogo Antarctic Research Station was built in 2014, which affects greatly on the sailing of an icebreaker research vessel. In this study, we analyzed the optimum sea route and sailable period of the icebreaker to vi ..."

to visit the Jangbogo Antarctic Research Station by using sea ice concentration data observed by passive microwave sensors such as Special Sensor Microwave/Imager (SSM/I) and Special Sensor Microwave Imager/Sounder (SSMIS) for the last decade, and by using sea route of the Araon, an icebreaker of Republic

High-resolution maps of the sea-ice concentration from MODIS satellite data

by unknown authors
"... [1] For realistic simulations of the atmosphere-sea-ice-ocean interaction in polar regions, maps of the sea-ice concentration of up to one kilometer resolution are needed. In the present paper, an algorithm is described, which is able to derive such maps based on satellite data from MODIS (Moderate ..."

Sea ice concentrations in the Weddell Sea: A comparison

by W. M. Connolley - of SSM/I, ULS, and GCM , 2005
"... [1] The sea ice fraction in the interior of the pack, especially in winter, is important for climate studies and for validation of sea ice models. When ice concentration is high, a difference of only a few percent in ice fraction can have a major effect on the ocean-air fluxes. Satellite estimates o ..."

Satellite thermal microwave sea ice concentration algorithm comparison

by S. Andersen, R. T. Tonboe, L. Kaleschke
"... temperarture, sea ice extent and area trends. Seven of the most common radiometer algorithms, used to compute the sea ice concentration, are compared to ScanSAR data estimates of ice concentration. Our focus is on the near 100% ice cover in winter. The sensitivity of the algorithms to the variable s ..."

2008: Evolution of Arctic sea ice concentration trends and the role of atmospheric circulation forcing

by Clara Deser, Haiyan Teng - Geophys Res Lett
"... [1] The retreat of Arctic sea ice in recent decades is a pre-eminent signal of climate change. What role has the atmospheric circulation played in driving the sea ice decline? To address this question, we document the evolution of Arctic sea ice concentration trends during the period January 1979–Ap ..."
