Physical analyses of the Dome Fuji ice core have been carried out to reveal fundamental properties of the core : (1) Stratigraphy, (2) Bulk density by a volumetric method, (3) Bulk density by an x-ray transmission method, (4) Total gas content, (5) Permeability and bubble volume, (6) Distribution of air-bubbles, (7) Distribution of clathrate hydrates, (8) Raman spectral N_2/O_2 ratios of air-bubbles and clathrate hydrates, (9) Ice fabrics, (10) Ice grain size, (11) Laser scattering tomography, (12) DC-ECM and AC-ECM, (13) Mechanical test, and (14) Crystalline structures of ice and clathrate hydrate. In the present paper the main results obtained so far are summarized.
