Notes
Slide
shows
Javis
Moyers
, in the
gray
jacket
, a
Professor
from the
University
of
Arizona
, and in the
red
flannel
shirt
is
Maryland
graduate
student
Dave
Finningan.
The
helicopter
pilot
in the
white
jacket
is
observing
them.
They were
collecting
gases
using
the
cryogenic
collector
out
at
one
of the
hot
vents.
The
gases
are
collected
using
a
dry
ice
system
so
that
anything
that
contains
a
volatile
metal
component
will be
condensed
in
collection
tubes.
These then
can
be
analyzed
for the
volatile
metallic
content.
The
materials
also
pass
through
a
filter
to
remove
particles
so
that there will
only
be
gaseous
materials
being
condensed
out
of the
high
temperature
vents.
This
is
in the
debris
flow
in
front
of the
crater.
