Extinction Coefficient of Light of Cores Drilled at Mizuho Station, East Antarctica

The extinction coefficient of light of shallow ice core samples obtained at Mizuho Station, Antarctica, was measured and its dependences on the depth from 10m to 110m, the density in the range of 0.55-0.88×(10)^3kg・m^<-3>, and specific surface area of grains were investigated. The value of ext...

Description
Summary:The extinction coefficient of light of shallow ice core samples obtained at Mizuho Station, Antarctica, was measured and its dependences on the depth from 10m to 110m, the density in the range of 0.55-0.88×(10)^3kg・m^<-3>, and specific surface area of grains were investigated. The value of extinction coefficient decreased and asymptoted to a definite value with the increase of depth.
