Digital Image Analysis

Using high-resolution satellite imagery provided by the Polar Geospatial Center (PGC), and displayed in BU’s immersive Digital Image Analyses Lab (DIAL), we will map the distribution of climate-sensitive landforms throughout Northern Victoria Land between the Convoy Range and Cape Adare. This work will produce geospatial products to aid the scientific community.  In addition, the group will investigate the potential for extensive surface melting and ice-sheet retreat with modest warming in areas north of the Dry Valleys in Northern Victoria Land. The hypothesis is that if key landform elements of the Dry Valleys assemblage are lacking in NVL it suggests a major variation in current climate conditions, and perhaps changes in climate evolution. The proposed work will demonstrate the potential for using geospatial imagery in geomorphic research and produce geospatial products that can be used by other researchers. More effective use of satellite imagery by field scientists in Antarctica will help reduce the logistical footprint on the continent and forge stronger links between PGC and Boston University’s Digital Image Analyses Lab.
