            "title": "Subsidence in California's Central Valley",
            "description": "This animation shows, in exaggerated terms, how the surface of the southern Central Valley of California deformed from the period 2007 to 2011. Interferometric data from the Japanese ALOS PALSAR imaging radar was used to measure the deformation, shown in color overlaid on an ASTER image. The large subsidence \"bowl\" that developed over this time period was caused by withdrawal of groundwater, causing subsurface layers to compact. Interferometric synthetic aperture radar, or InSAR, can be used to monitor subsidence in order to prevent groundwater overdraft and irreversible compaction of aquifers. ALOS PALSAR data is copyright JAXA/METI and was provided by the GEO Supersites and the U.S. Government Research Consortium datapool at the Alaska Satellite Facility. || ",

            "title": "Pine Island Glacier Ice Flows and Elevation Change",
            "description": "This animation shows glacier changes detected by ATM, ICESat and ice bridge data in the highly dynamic Pine Island Glacier. We know that ice speeds in this area have increased dramatically from the late 1990s to the present as the ice shelves in this area have thinned and the bottom of the ice has lost contact with the bed beneath. As the ice has accelerated, ice upstream of the coast must be stretched more vigorously, causing it to thin. NASA-sponsored aircraft missions first measured the ice surface height in this region in 2002, followed by ICESat data between 2002 and 2009. Ice Bridge aircraft have measured further surface heights in 2009 and 2010, and these measurements continue today. Integrating these altimetry sources allows us to estimate surface height changes throughout the drainage regions of the most important glaciers in the region. We see large and accelerating elevation changes extending inland from the coast on Pine Island glacier shown centered here. The changes on Pine Island mark these as potential continuing sources of ice to the sea, and has been surveyed in 2011 by Ice Bridge aircraft and targeted for repeat measurements in coming years. || ",

We know that ice speeds in this area have increased dramatically from the late 1990s to the present as the ice shelves in this area have thinned and the bottom of the ice has lost contact with the bed beneath.

Integrating these altimetry sources allows us to estimate surface height changes throughout the drainage regions of the most important glaciers in the region. We see large elevation changes at the coast on Thwaites glacier, at the center of the images, and large and accelerating elevation changes extending inland from the coast on Pine Island and Smith glaciers, to the left and right of the images, respectively. The changes on Pine Island and Smith glaciers mark these as potential continuing sources of ice to the sea, and they have been surveyed in 2011 by Ice Bridge aircraft and targeted for repeat measurements in coming years. || ",
