On Tuesday, we reviewed “dissolved
oxygen” with Sherril. We discussed how it is added to and removed from a
system. We also talked about what influences and affects dissolved oxygen
levels. Sherril gave a small introduction to “experimental design”. We
formulated a simple hypothesis to test how dissolved oxygen differs between
inside an algal canopy and directly outside of an algal canopy.
Later, we divided into groups and
went out into the pond to do some field work on algal cover for Sherril’s
research.
First, we set up our “Algal Cover”
Kit.
Then, we went out to collect data
and samples.

On
Saturday, Koa gave a brief intro to dissolved oxygen for the interns and the
Ocean Awareness Training (OAT) visitors.

Later, we collected samples of
dissolved oxygen through field work to test our hypothesis and performed
titration to collect dissolved oxygen data.

All in all,
it was a fun week filled with experiments and collaborating in an effort to
design our own experiment. It was great and fun meeting new people (OAT) and
being able to introduce them to a little science. (:
