the backscatter in vertical and horizontal polarization, the active polarization ratio (APR) and the daily standard deviation, are sensitive to ice types and are strongly correlated with ice concentration when the relationship is expressed in exponential form. Our study showed that the APR is especially suitable for ice–ocean separation, and a threshold of(More)

In the United States, satellite Synthetic Aperture Radar (SAR) imagery from the Canadian RADARSAT-1 satellite are being used routinely by the National Ice Center (NIC) in the production of sea ice analysis charts. The routine production of other SAR ocean products is also being demonstrated by the National Oceanic and Atmospheric Administration (NOAA)(More)
Synthetic Aperture Radar (SAR) data from the Canadian RADARSAT-1 satellite is used operationally by the U.S. National Ice Center (NIC) in the production of sea ice analysis charts. The quasi-operational production of other SAR products has also been demonstrated by the National Oceanic and Atmospheric Administration has supported the development of SAR(More)
Geography is the study of the relationships between people and their environments, relationships that vary from place to place over the Earth. Students inquire into those factors responsible for the variable and changing character of Earth's surface, which over time has been transformed into the human habitat. Geography integrates physical science, social(More)
