Abstract :
In August of 2008 a radar survey was conducted at the NEEM site in Greenland. An example echogram showing internal layers all the way to the bed, a digital elevation map around the drill site, and a side looking synthetic aperture radar image will be presented. The echogram appears to show a fairly continuous Eemian layer where predicted by modeling. Additionally the area around the drill site is very flat although some slope variation is observed. Finally side looking SAR images show reflected power variations that need more analysis to determine their source.
