=Overview= spatial resolution across the firn/ice transition. make measurements and proper cores from there, because the bubbles look different than at the other sites, but the access was only possible on foot, so we could not take our instruments onto the icefield.)
 * Additional transect with cores and albedo measurements, with high
 * Additional measurements along the transect:
 * Photos of a flat board over the ice surface to estimate surface roughness of the ice.
 * Shallow cores for density and bubble-photos from all sites with cores.
 * Photos of cracks in the ice were taken at albedo sites to quantify the influence of numerous cracks on albedo.
 * Core and albedo from Texas Bowl (vicinity of elephant moraine).
 * Snow:
 * Snow albedo combined with Martin's measurements of snow properties for different snow surfaces (including cast snow samples for analyzing).
 * temperature profile in 1.4 m snowpit
 * density profile in the top 50 cm
 * 2 m and 5 m snow core for analyzing
 * snow samples from inside "crevasse-blisters" (showing very large crystals)
 * Shallow core transect across a tephra-layer/clean-ice boundary for analyzing.
 * Surface sample from shimmering icefield for analyzing. (We tried to
 * Surface sample from Byrd Glacier blue ice area for analyzing (courtesy Gordon Hamilton and Leigh Stearns)
