To better understand processes affecting the ice sheets and to supply boundary condition information into ice sheet models and ice thickness for other ice sheet analysis, the Center for Remote Sensing of Ice Sheets (CReSIS) has designed, developed, and deployed several multichannel radar depth sounders in Greenland. This dataset contains data collected mostly around outlet glaciers in Greenland, including dense grids around Jakobshavn, Helheim, and Kangerlussuaq glacier channels, with the specific purpose of improving understanding in this dynamic and fast changing part of the ice sheet. These KML files show the location of each data frame and data segment for the radar echograms in the dataset. Files are named according to the formats: Browse_Data_{$segment_id}.kml and Browse_{$season_id}.kml. Only a few data points are included to allow for quick download and browsing. There is one KML file per segment and then one KML with all segments (entire season). The per segment files contain information per frame and more data points. The season file contains information for each segment and fewer data points. More information can be found in “Readme.pdf”.
