AMASE 2007: Last Day in Bockfjorden
08.18.07
Today was our last day in Bockfjorden. The first scheduled activity was to
get everyone out to the first rover field test site so those of us hidden
in the darkened SOWG room could see how inaccurate our interpretations of
the rover images really were. To me, this was the most fun part of the
exercise. In reality, the rover site was much steeper than we had imaged.
Scale can be completely lost without any of those commonly unnoticed scale
markers we usually have on Earth... say... oh... plants. The rover
site turned out to be
much steeper and smaller than any of us had predicted.
After this insightful experience we split into three groups. One went back
to the boat, one went up to sample the ice caves and one hiked all the way
to the top of Sverrefjell to begin a 25m transect sampling of weathered
olivine and soil down the volcano. I was part of this latter group as was
Paulo, a JPL engineer on the Cliffbot rover team. Paulo had his first day
off the boat only two days before and seemed to enjoy being out again. As
Jen, Hans, Marilyn and I collected samples, Paulo was one of the extras
who joined us to help collect. It was fun having him along and so I
thought I'd have him share some of reflections on the experience.
> From Paulo:
Being on top of Sverrefjell was an awesome sight, being surrounded by
pointed snowcapped peaks all around, deep fjords below carved out by years
of glacier activity, and our tiny blue ship, the Lance, resting in
Bockfjord far off in the distance behind a layer of fog and snow. The wind
was frigid and crisp, and filled with snowflakes that lightly prickled
your face. It felt as we were on top of the world; and then we began
our steep decent down
the volcano. Our mission- collect geological and biological samples every
25 m of altitude. With GPS in hand, we skied down the screen-covered
slopes, searching for outcrops and marking coordinates for each of our
sample sites.
Being a robotics engineer from JPL, I had gotten used to digging for rock
samples through computer control of a robotic arm. However, this time
around, I had the chance to take on the role of a real geologist. Armed
with a hammer, I swung away at an outcrop, breaking free fresh xenoliths,
collecting the green olivine crystals with foil for future analysis.
After six hours of hiking 400 meters down the hard, rocky face of
Sverrefjell, we ended up on the soft, spongy tundra at the base. It was
9pm- you would never know if from the 24-hour daylight, however, our
bodies' definitely felt it being the end of a rough day and time for a
break. We finally made it back to the Lance, greeted by friendly faces and
ice cold drinks for everyone on the team. The transect down Sverrefjell
was an adventure and experience you could only find on the arctic island
of Svalbard through AMASE.
