data analysis and field trip
Post date: Jul 30, 2012 7:43:09 PM
Over the past week, I've been very busy with finishing up various
things for my AGU abstract, and preparing for my final presentation.
As of now, I have eight speleothem records that we've been able to
compile in the same form. These consist of data in tables on excel,
that have been plotted on a very useful application called datagraph.
Here, we have been visually comparing the oxygen, and uranium isotope
ratios. After looking at these, three out of four sections of the data
correlate to each other. This indicates that both of these
measurements can be used to look back on ancient rainfall records.
I'm working in the clean lab, wearing a bunny suit.
On Wednesday, our whole group traveled to Los Trancos Open Space
Preserve to find some first hand evidence of earthquakes and fault
lines. We found both. First off, was the famous displaced fence that
has moved a couple feet over the past hundred years. We measured how
far the fault (and the fence) have moved since then. Also we found a
couple of Sag Ponds, that can only be created by strike-slip faults
like the San Andreas. Another piece of evidence that we found, was two
or three trees that had almost fallen all the way over in either the
1906, or the 1989 earthquake, and had grown back up towards the
sunlight. This created oddly shaped branches on the trees.
