Asset Details

  • Description:
  • a) Bedrock and lake surface elevation in m above sea level referenced to the WGS 84 ellipsoid. White dashed line marks shore line of Lake Vostok. Dashed contours mark 100 m interval and solid contour lines mark 500 m intervals. Numbers refer to discussion in text. White lines mark locations where we observe the accreted ice reflector in the radar data and yellow lines indicate locations with fuzzy lake reflectors coinciding with the regions of melting (A. A. Tikku et al., manuscript in preparation, 2004). b) Gravity anomaly used for the inversion process. The gravity effect of the ice sheet has been removed from the free‐air anomaly. Contour interval is 10 mGal. c) Bedrock elevation in m estimated from gravity inversion. Contour interval is 100 m. White circles mark depth estimates from seismic soundings shown in Figure 3. d) Bathymetry estimated from gravity inversion and lake surface elevation. Contour interval is 100 m. The positive water depths reflect inconsistencies within the uncertainty of the aerogravity data. White boxes indicate regions with grounded ice observed from radar.
