Sunny skies, partly cloudy
High winds in the morning sped the ship up to a swift 5.4 knots, a refreshing wakeup for C Watch after a good night’s sleep. B watch took the deck at 0700 after a hearty breakfast of eggs and chocolate chip pancakes. B watch started the day with a science station at the Wilkinson Basin, deploying the CTD to a depth of 200 m – our deepest drop yet! Data was processed by C Watch in the afternoon.
C Watch mustered at 1100 for a fun craft class - sunprints. We assembled a bucket full of random objects from the boat like seaweed and ropes and placed them on top of cyanotype fabric. After 15 minutes in the sun, their shadows were perfectly printed onto the fabric. A and B Watch can’t wait to follow our awesome crafting.
At 1300, C Watch took the deck. The Labbies were in charge of doing the 50 count of phytoplankton and 100 counts of zooplankton under the microscope. The samples were collected from the neuston and phytoplankton net this morning. We were surprised to find an accumulation of radiolarians! Radiolarians are a type of zooplankton that look like tiny red pompoms. Sorting through the radiolarians, we found a lot of copepods, which became the topic for an activity during class today!
Class started at 1430 with a presentation on data from the CTD and a lesson about copepods! Copepods are the most common type of zooplankton, which is why we found many in the 100 count. Copepods have evolved to have a variety of favorable traits, including sensing antennae and buoyancy control. After learning this, we split into groups to create our own idealistic copepods! Some creative inventions were called Blort, the
Charismatic Copepod, and the Diatom Shredder 3000. After that, we learned about the Beaufort scale, the system by which sailors refer to wind and sea conditions, specifically the force of the wind. The 12 point scale has a variety of rather poetic phrases to describe each level of wind force, including “white horses” and waves as “rippling scales.” After drawing out of a hat phrases used to describe the wind, we created a chain of haikus, known as a renga, which was a blast to read at class.
As the sun sets low in the cloudy sky, C Watch is about to enjoy a full night’s sleep with our bellies full of shepherd’s pie. We continue to sail on subtle winds around Jeffrey’s Ledge, our final superstation, which C watch will command tomorrow!
