Operational Segmentation and Classification of SAR Sea Ice Imagery
The Canadian Ice Service (CIS) is a government agency responsible for monitoring ice-infested regions in Canada’ s jurisdiction. Synthetic aperture radar (SAR) is the primary tool used for monitoring such vast, inaccessible regions. Ice maps of different regions are generated each day in support of navigation operations and environmental assessments. Currently, operators digitally segment the S...
متن کاملAustral Summer Sea Ice Melt Revealed in Antarctic ERS-1/2 and NSCAT Scatterometer Data
Introduction The first in-situ field observations of Antarctic austral summer sea-ice melt were made in the Bellingshausen Sea by Arctowski (1908) on Belgica in 1899, and later by Wordie (1921) during the ill-fated drift of Endurance in the Weddell Sea from 1914-1916. It has been 100 years since these pioneering ship drift experiments, yet little more is known about the spatial extent, duration...
متن کاملAlbedo of summer snow on sea ice, Ross Sea, Antarctica
[1] Surface all-wave albedo and physical parameters (grain radius, mass density, surface temperature, and stratification) of an austral summer snow cover on sea ice were measured in the Ross Sea during January-February 1999. It was observed that (1) from north to south the snow surface temperature decreases, albedo increases, snow mass density decreases, snow composite grain radius decreases, a...

متن کاملUsing Temporal Information in an Automated Classification of Summer, Marginal Ice Zone Imagery
Synthetic aperture radar (SAR) imagery is difficdt to classify under summer melt conditions, even with the human eye. BackScatter instability causu the intensities of the fiistyear ice, multiyear ice, and open water classes to intermix, thus making an intensity-based classification invalid. The method p~nted in this paper supplements backscatter information from SAR data with wind and temporall...
