Surface roughness characterizations of sea ice and ice sheets: Case studies with MISR data
Abstract—This work is an examination of potential uses of multiangular remote sensing imagery for mapping and charac-terizing sea ice and ice sheet surfaces based on surface roughness properties. We use data from the Multi-angle Imaging SpectroRa-diometer (MISR) to demonstrate that ice sheet and sea...

We use data from the Multi-angle Imaging SpectroRa-diometer (MISR) to demonstrate that ice sheet and sea ice surfaces have characteristic angular signatures and that these angular sig-natures may be used in much the same way as spectral signatures are used in multispectral classification. Three case studies are examined: sea ice in the Beaufort Sea off the north coast of Alaska, the Jakobshavn Glacier on the western edge of the Greenland ice sheet, and a region in Antarctica south of McMurdo station containing glaciers and blue-ice areas. The MISR sea ice image appears to delineate different first-year ice types and, to some extent, the transition from first-year to multiyear ice. The MISR image shows good agreement with sea ice types that are evident in concurrent synthetic aperture radar (SAR) imagery and ice analysis charts from the National Ice Center. Over the Jakobshavn Glacier, surface roughness data from airborne laser altimeter transects correlate well with MISR-derived estimates of surface roughness. In Antarctica, ablation-related blue-ice areas, which are difficult to distinguish from bare ice exposed by crevasses, are easily detected using multiangular data. These unusual ablation surfaces are smooth and, unlike nearby crevassed ice, are strongly forward scattering. These case studies demonstrate that MISR data can make an innovative and important contribution to remote sensing of ice sheet and sea ice surface properties.
