SummaryThe polar region plays an important role in the Earth system. Glacier and sea ice covered oceans and lands in polar regions have been identified as sensitive indicators of global climate change. As a team with vast experience in InSAR, SBAS and PolSAR for geophysical parameter retrieval, we propose to monitor change detection of snow and sea ice by providing space-based observations. We propose to use the TerraSAR-X new modes of observations (Staring Spotlight and 6 Beam Wide ScanSAR) to monitor sea ice and glacier movement over the polar region. The aim is to detect possible significant dynamic change of glacier and sea ice, which is related to global and seasonal climate change. Polarimetric and interferometric processing in time-series will provide various types of maps of sea ice and glacier displacements, which will enable us to detect and better understand environmental phenomena that may affect to climate change. The proposed study includes investigation of melting ponds in sea ice. We expect that the Staring Spotlight mode enable us to provide very high resolution maps of characteristics of sea ice and glacier movement because of its high spatial resolution. Especially we expect to observe the size of sea ice and melt pond in the sea ice more accurately. On the contrary, the 6 Beam Wide ScanSAR mode has very large swath coverage, so that we can measure the larger regional movement of glacier and sea ice using cross-correlation coefficient tracking approach, etc. Once study region are selected, we will perform a field campaign using icebreaker ship over polar region. The Korea Polar Research Institute (KOPRI) has been performing such campaigns every year using ARAON, which is a Korean icebreaker, for scientific research in the polar region. The ARAON provides logistics to polar research stations and carries state-of-the-art research equipment for conducting geophysical, biological, oceanographic research. Both space-based and icebreaker ship-based measurements will provide complementary cooperation in scientific and practical use.
