Note (General): The knowledge of ocean tides underneath permanently or seasonally sea ice covered ocean and ice shelves over Antarctica, is poorly known at fine-spatial scales. 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.
