To better understand how environmental signals are fixed in snow stratification, two 4m deep pits and two 2m deep pits were dug at several locations. Snow samples were collected for purposes of physical analysis. From the samples, following analyses are to be done: (i) dielectric properties, (ii) density, (iii) 3D structure of pore space, (iv) crystal orientation fabrics and (v) salt inclusions. ... Samples were collected as 50cm long blocks. Physical structure of the snow stratification was also investigated. Chemical analysis will be done using snow from the same pits. They are described separately.
Site name, location, depth of the pit and date of the pit work are as follows.
(i) Dome Fuji
4 m, 2007-12-10 to 2007-12-13
The location for the pit was (77°17.90’ S, 39°47.13’ E) about 3 km NE from the station.
(ii) CMOS-AWS point (76° 48’ S, 31° 54’ E, 3742 m above sea level)
2 m, 2007-12-20
(iii) JASE Meeting point (75°53’S; 25°50’E; 3661 m a.s.l.)
4 m, 2007-12-24 to 2007-12-26
