Chemistry data of shallow snow samples during the JASE traverse 2007/2008
Listed in NASA Earthdata CMR
To better understand how environmental signals are fixed in the snow stratification, two 4m deep pits and two 2m deep pits were dug at several locations.
Description
Snow samples were collected for purposes of chemical analysis. From the samples, following analyses are to be done: (i) stable isotope of oxygen and hydrogen, (ii) major ions, (iii) dust and (iv) trace metal.
Spatial resolution of the sampling was 2 cm. Major ions and stable isotope will be analysed at the National Institute of Polar Research, Japan. Snow sampling for trace metal elements were requested from Dr.

Hong in South Korea. Physical structure of the snow stratification was also investigated. It is described separately.
Site name, location, depth of the pit and date of the pit work are as follows. (i) Relay Point (74°0’S, 43°00’E, and 3353-m above sea level) 2 m, 2007-11-30 (ii) 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. (iii) CMOS-AWS point (76° 48’ S, 31° 54’ E, 3742 m above sea level) 2 m, 2007-12-20 (iv) JASE Meeting point (75°53’S; 25°50’E; 3661 m a.s.l.) 4 m, 2007-12-24 to 2007-12-26
