11-01-02—Today as we prepared to climb
the mountain, many science activities took place:
STROMATOLITES: (Nathalie,
Edmond, and David)—Overall
we took measurements of the stromatalites; most
have about the same height, no matter where you
are in the field. This field of stromatalites
is at least 100 square Km, and I wouldn’t
be surprised if it were bigger than that. The
structures vary in all sorts of shapes. From domes
to columns to mushroom shapes, we have found four
or more types here. It is a very interesting find.
The placement of these types suggests that it
looks like they are related to the environment
in which they occur. But this is just one possibility.
MARVIN (Marc
and Christian)—we
worked on replacing one of the motors today and
we worked on the axle as well to prepare for some
field tests.
LAGUNA BLANCA SAMPLES (Andy
and Lorena)—we
discovered small thermal upwellings and the color
distribution of the springs is like Grand Prismatic
springs in the US. The importance of this is that
anywhere there is green in the Lagunas, this indicates
some sort of upwelling. This would indicate Carbon
Dioxide rich water. The area is rich with geothermal
activity.
