MODIS.jpg (128.41 KB)  | JPEG Image (.jpg) | Figure A shows the division of McMurdo Sound into six zones; fast ice areas were generated manually from clear-sky images by drawing polygons in GIS software, and pack ice was excluded from analysis. The fast ice in MODIS scenes was sometimes obscured by clouds, so for days with missing imagery we interpolated linearly between valid data. Areas of persistent multiyear ice or glaciers that were not considered in the analysis (white in the figure). Figure B shows the total of seven pixels in the 25 km polar stereographic projection that encompassed McMurdo Sound; for each pixel, daily or bi-daily fractional sea ice cover was extracted. SSM/I passive microwave sea ice observations do not distinguish between fast ice and pack ice. There are small amounts of land and ice shelf contamination in pixels 1, 2, 5 and 7. |
