Souls on Board

Today was another exciting day aboard the Cramer! I woke up this morning and had some extra delicious blueberry muffins for breakfast. I had morning watch this morning and today I was finally in lab, the first time since leaving Bermuda. Usually when I enter the lab, I always glance to the little shelf near the port side porthole where the cool specimens from the previous evening's science station  are kept so everyone can see them. I was especially excited once I walked into the lab this morning because I saw a creature that I didn’t even know existed- a Paper Nautilus. At first I thought there was a little octopus and a snail in the jar, but after further observation  and reading in the invertebrates textbook, I found out that the little octopus lives in this shell, much like a real nautilus. What makes this even more fascinating is that the octopus (only the females) build a shell around themselves and hold on to it with two specialized tentacles! What a fun way to start the day!

The rest of the day consisted of a lot of work. I assisted the JLO with the morning station, by performing the wire driver duties during the CTD deployment. If you were wondering, the CTD is a measurement device we send down 500 to 1000 meters and it measures conductivity (salinity), temperature, depth, oxygen, and chlorophyll-a concentration. We use this data to learn more about the water masses that we sail through. During morning watch we had a policy class with our professor, Mark, where we discussed case studies based on the bridging relationships between the general public, NGOs, and government, as well as the distinction between government and governance in the world of public policy.

After we finished morning watch, I began working on completing my sheet anchor, which is a notebook that includes all the necessary information for sailing the Corwith Cramer. Writing this sheet anchor was especially urgent because I need it to help me for the Nautical Science practical exam tomorrow! We had another class at 1430 with Mark and Laura, where we discussed the Hudson Canyon (it's really cool, you should google it) and the effectiveness of a proposal to make this area an ocean sanctuary. We also learned we will be helping the New York Aquarium gather information about the Hudson Canyon to help educate the public about this interesting landscape, how cool is that?! After this I worked on my sheet anchor again until I had to retreat to my bunk so I could get some sleep before my next watch, which happens to be the dreaded dawn watch.

Ridge, this is the cutest blog post I have read on your programs site. The way you describe the nautilus is adorable. I am so happy to see another post from you.We have to make a visit to the New York Aquarium so you can show me the information you shared with them! Proud of you and all you are doing on that fascinating ship!
