On Tuesday it was time to turn in all of our work for the fishes section and take the final, with a final goodbye to Su until our group research projects during week seven. The fun with fishes continued that night while everyone was taking a much needed break before starting algae, with the conversation still returning to adipose fins and dorsal spines. Thank you Su for such an exciting and intensive crash course in fish of the Pacific Northwest.
A variety of algae in tidepools at Seal Rock
Seal Rock Beach April 2015
Our next section on marine algae started Wednesday afternoon with the very ecstatic and enthusiastic Annette Olson. We started off the section with a couple of lectures, including one from Chenchen Shen, a graduate student at OSU, and her research on coralline algae. Groups of two or three were then assigned a taxa where we have to find, collect, and identify specific species from that taxa, while keeping an eye out for our treasure taxa. Our treasure taxa are specific species that we will use to demonstrate to the class the ecology of our taxa.

After getting into our groups, the whole class enjoyed a nice break with some tea before diving into our first algae lab. During the lab, we went around and tried to guess certain morphological features on given algae, which ended up teaching us that you can’t judge an algae by its color. Halfway through the lab, Miram poured hot water on five specimens from the three different phyla, and all but one “magically” changed color to green! The only one that stayed the same color was a green algae. We even learned how to press the algae!

On Thursday, we woke up bright and early and ventured to Seal Rock for the first time this term. Annette showed us all around the beach, taking us to four different spots and helping us find and identify our taxa. Her helpful and essential husband, Charlie, followed the class around and took pictures of his wife while she lectured, he also made sure that she ate later in the day! Once we were back at Hatfield, we cleaned our collections and put them in the respective tanks. After lunch and lectures, we returned to the lab and Annette taught the class how to identify algae with a dichotomous key and how to cross section them.

Originally we were supposed to go to Boiler Bay on Friday, but due to the high waves and rainy weather, we ended up switching our Monday and Friday schedule. So instead of spending more time at Boiler Bay, we enjoyed a nice and relaxing half day of lectures and labs. Hello early weekend!
