Program Overview
|
|
|
NOVA follows glaciologists into the underworld of Mont Blanc, where
they search for internal lakes.
The program:
-
revisits the 1892 disaster in which a hidden lake burst forth
from a glacier on the French side of Mont Blanc, killing more
than 100 people.
-
features glaciologist Luc Moreau, who explores a "water well"
(an ice shaft formed by meltwater) to try to predict future
flood events.
explains how a glacier forms. -
relates some of the problems of being in an unstable
environment, where water is always changing from liquid to solid
and back again.
-
follows Moreau into his lab inside Mont Blanc's Argentiere
Glacier, where he measures the movement of the glacier and tries
to determine where the water flows.
-
introduces Carsten Peter, an ice adventurer who explores and
photographs ice caves.
-
features Peter's dive into a water well inside the Mer de Glace,
the largest glacier on Mont Blanc, and shows all the equipment
needed to make a dive at extremely cold temperatures and at high
altitude.
-
shows the methods Peter and Moreau use to try to determine
whether there are any interior lakes.
Taping Rights: Can be used up to one year after the program
is taped off the air.
