Significant amount of West Antarctic ice sheet melt is through the mechanism of basal melting and due to turbulent tidal mixing. We originally proposed to use the ALOS L-band PALSAR to model ocean tides underneath Antarctic ice-shelves. However, due primariy to its long repeat-orbits of 46-days, we are largely unsuccessful to construct coherent interferograms over the Filchner Ronne Ice Shelf (FRIS) using ALOS PALSAR. As a result we conducted a study using ERS-1/-2 tandem mission data to demonstrate the estimation of O1 tides over the Sulzberger ice shelf, Ross Sea, West Antarctica. We used ALOS along with satellite radar altimetry as vertical reference to construct high-resolution (ca.40 m) water level changes in vegetated wetlands, including Louisiana, Helmand River, Amazon wetland, and the St. Clair Flats wetland in the Great Lakes. We also demonstrated the use of ALOS PALSAR to measure permafrost surface subsidence over the Tibetan Plateau, and thus inferring its Active Layer Thickness (ALT) change., 形態: カラー図版あり, 形態: DVD-ROM1枚, Physical characteristics: Original contains color illustrations, Note: One DVD-ROM, 資料番号: AA0065135008, レポート番号: JAXA-SP-11-007E}, title = {Study of Tidal Dynamics, Wetland Hydrology and Permafrost Degradation Using ALOS PALSAR Interferometry}, year = {2011} }
