Taking it all In
Everyday, I try to find a few minutes to absorb the quiet beauty of this continent. Yesterday, we drove the Piston Bullies out to Cape Evans again to dive for fish, sea spiders, and even plankton. While waiting for the divers, I had a few minutes to step outside and just listen to the silence.
With the wind still for the moment, I could listen to the most absolute silence I have ever heard. No birds chirping in the background. No humm of insects. No howling coyotes. No leaves rustling. There is utter emptiness for miles upon miles. Facing some directions, there is unlikely to be another human- or even living organism- for hundreds or thousands of miles. Many places, there has never been a human step foot. It makes you think. This pristine environment must be protected. It also reminds me just how lucky I am to be here.
Our scientists have turned us loose to create a project of our own for you to help us out with. We have decided to see the diversity and abundance of plankton at several locations around McMurdo Sound. I was interested in this because by class has studied diversity of benthic macroinvertebrates, and it would be a fun extension to study lake plankton too.
Here is how it is going to work...
Our question is ...Is there a greater variety of plankton species at Cape Evans(furthest away from McMurdo,, The Jetty(nearest to McMurdo), or Arrival Heights(midway)?
What is your hypothesis?
Protocol Part 1
We need to standardize our protocol so that all of our tests are comparable. Part 1- collecting plankton 1. Drop the plankton net to the full length of the rope. 2. Pull the plankton net up 3. rinse collection cup into collection bottle. 4. Repeat steps 1-3 a second time.
Back at the lab, we are going to filter some of the water out of the collection jar, and then try to count our catch. How many organisms do you think we will find? How many different types or organism? Do you think we will find more plant like, or animal like plankton?
Stayed tuned tomorrow to help us identify the plankton we find!
Our B-207 team is carefully monitoring all of our fish and their tanks as they are trying to acclimate to their environment. We check the whole system and temperature of every bucket every day. They check the pH twice each week, and they check alkalinity once a week. They also keep a close eye on the carbon dioxide system to make sure the concentrations stay stable. It is important to monitor these systems and ensure they are all running properly.
Today's shout out goes to Arroyo Seco in Greenfield fifth graders from Ms. Smith's class. Thanks so much for having me come to your class and signing a penguin for me to bring!
Tomorrow we are going out to "The Jetty" to collect more fish. We need a few adults as well as some more T. pennellii. I'm looking forward to another day outside doing science!
