Ice core stratigraphy measurement, digital camera recording of the ice core, and measurements of bulk density and electrical conductivity of ice (ECM) were conducted in situ. Snow pit observations were carried out at three different sites. Fresh falling snow, drifting snow and surface hoar were sampled.}, pages = {253--260}, title = {Activities of the Japanese Arctic Glaciological Expedetion in 1999 (JAGE 1999) (report)}, volume = {54}, year = {2001} }
