As part of ice-albedo feedback studies during SHEBA, we measured spectral and wavelength-integrated albedos. Measurements were made at least weekly every 2.5 m along a 200-m survey line from April through October. Initially this line was completely snowcovered, but as the melt season progressed it became a mixture of bare ice and melt ponds. Observed changes in albedo were a combination of a gradual evolution due to seasonal transitions and abrupt shifts resulting from synoptic weather events. Surface conditions evolved from dry snow (April-May) to melting snow (June 3) to early melt ponds (mid-late June) to fully developed melt ponds (July-August). From June through August albedo measurements were made every other day. For additional documentation, start with the spectalb.htm file contained in the zip file html-metadata.zip.
