An
international panel of scientists discussed
research conducted at Lake Vostok in Antarctica
during a press conference on Tuesday,
May 28, as part of the American Geophysical
Union's 2002 Spring Meeting in Washington,
D.C. The panelists, from the left, are:
Robin Bell of Columbia University's Lamont-Doherty
Earth Observatory; Jean Robert Petit of
France's Laboratoire de Glaciologie et
Géophysique de l'Environnement du CNRS;
Sergei Bulat of Russia's Petersburg Nuclear
Physics Institute; and John Priscu of
Montana State University.
|
 |
Priscu introduces the subject of subglacial
lake exploration and briefly reviews where
researchers are today and where they hope
to be in 10 years.
|
 |
Bell explains the dynamic interactions
between water and ice at Lake Vostok,
using an animation based on her analysis
of radar data.
|
|
Petit briefs reporters on the chemical
composition of lake ice, x-ray tomography,
and likely hot spots beneath the lake.
|
|
Bulat describes the meticulous processing
of ice core samples to avoid contamination
and the findings from DNA work on accretion
ice.
|
|
After the brief presentations,
the panelists respond to questions from
members of the news media.

webcast is available for viewing.
