Stable isotope data of surface snow and snow temperature data at 10 m depth, obtained during the JASE traverse 2007/2008
Listed in NASA Earthdata CMR
To better understand the relation between stable isotopes in snow and annual mean temperature, surface snow samples were collected and temperature of snow at 10m depth was measured once a day at each camp site.
Description
Surface snow of 2~3 years was sampled. In coastal areas the depth was ~1 m but in inland, the depth was shallower. 10-m snow temperature measurement was always coupled with the snow sampling for the stable isotope measurement.
We used a non-sampling type auger to make a hole for the temperature measurement. We set a thermo sensor at the bottom of the hole and waited until next morning for the measurement. K. Fukui led field work.

Sampling was done along a route connecting “Syowa – Mizuho – Dome Fuji – JASE Meeting Point (75°53’S; 25°50’E; 3661 m a.s.l.) – Dome Fuji – Mizuho – Syowa”. Snow samples will be analyzed for oxygen isotope measurements and deuterium measurement.
