... spanning 11 years and continuous GNSS observations at Vostok station over 5 years are used to determine the vertical firn ... better. Repeated measurements of surface height profiles around Vostok station using kinematic GNSS observations on a snowmobile allow the quantification of surface height changes at 308 crossover points. The height change rate was determined at 1 ± 5 mm/yr, thus indicating a stable ice surface height over the last decade. It is concluded that both the local mass balance of the ice and the lake level of the entire lake have been stable throughout the observation period. The continuous GNSS observations demonstrate that the particle heights vary linearly with time. Nonlinear height changes do not exceed ±1 cm at Vostok station and constrain the magnitude of spatiotemporal lake‐ ...

Repeated GPS observations spanning 5 years and long‐term surface accumulation data show that the height of the lake surface has not changed over the observation period. The application of the mass conservation equation to purely observational data yields an ice mass balance for Vostok station close to equilibrium.

Cupferron was used to determine its effect on the frequency of X-ray induced chromosomal aberrations in microspores of Tradescantia paludosa. Inflorescences were given pre- and post-radiation treatment in various concentrations of cupferron in conjunction with a total dose of 400 rads of X-radiation delivered in a helium atmosphere. Concentrations of cupferron of 10−2 molar or greater proved to be toxic but did not produce any radiomimetic effects in the form of chromosomal aberrations. Pre-treatment ...

Our data suggest an overall increase of the SMB during the observation period accompanied by a significant decadal variability. The main driver of this variability is local air temperature with an SMB temperature sensitivity of 2.4 ± 0.2 kg m −2 yr −1 K −1 (11 ± 2% K −1 ). A covariation between the Vostok SMB and the Southern Oscillation Index is also ...
