At anchor, Tarpaulin Cove
   
It is hard to believe our last day at sea is soon approaching. leaving our watch groups will be so sad but friends and family are missed at home and I’m sure we are being missed also! Today’s weather was calm, but our work for the day was keeping us busy! Our watch groups of 8 were split into two groups of 4 to present a detailed examination of data that we have been collecting throughout the course of our journey at sea. Combining the knowledge we learned at the shore component, we set up charts and graphs to present our topic, Surface Trends. This topic included salinity, temperature, light, current strength, and dissolved materials in the water as we have collected hourly tests of each characteristic throughout the past week. Every group’s presentation was very successful and much thought was put into every hypothesis. Each analysis highlighted the factors we had been retrieving from the ocean starting from day 1.

After presentations, in order to be prepared for tomorrow’s evaluations from John and Gary, we were asked to write a journal topic describing what this sea experience has inspired us to do. In my journal, I focused on the things that at home people seem to take for granted. On the ocean you realize your resources are to be used with regulation and care because unlike on land, you only have a certain amount of the necessities. When I get home, I know I will notice the things I use most often and how to use them wisely. I am inspired to be less wasteful and be more appreciative for the water, food, clothes, and technology I have at my fingertips. 
    Overall, today has been a great day of examining the data we have been gathering and enjoying being on the calm waters at anchor.

Ship’s Position: The Cramer’s current position is 40° 45.0’ N x 070° 59.0’
W. We are about 50 miles south of Nantucket, heading due North. 
Weather: Currently, it is cloudy with wind from the West , waves of about 6ft, and air temp of 24°C.

Today we collected samples from our 3rd and final superstation on the outer continental shelf. We deployed the Neuston Net, Sediment Grab, Secchi Disk, and Carousel. In the neuston net we collected red mesopelagic shrimp and brittle stars which were a pretty exciting find. In the lab we’ve done tons of data processing including: winkling (a form of titration to find the dissolved oxygen content of a sample), processing chlorophyll, and identifying zooplankton. We spotted two pods of dolphins today; they each spent a good while jumping excitedly alongside Cramer before going on their way. During class at 1430 we learned about the layout of the boat in more detail (including all the secret compartments and trap doors) as well as a short lesson from Gary on the light spectrum leading into a lab. We then learned more about visible light wavelengths by dropping colored M&M’s into the water and observing how many seconds it took for them to disappear. This evening’s sunset was nothing compared to this morning’s amazing sunrise because of the thick clouds. Tomorrow we get to do some intensive data analysis in the morning as well as in the afternoon.
This afternoon people who were not on watch enjoyed reading and hanging out in the bow spread and atop the lab rooftop. A guitar was busted out and we all had fun listening to songs and composing songs on the ukulele. We’re all pretty tired but after our watch tonight (and a midnight snack) we’ll have plenty of time for a good night’s sleep.

25 July 12

Hello, to all our folks at home!
So far, our trip has been full of excitement and education. Following some bouts of seasickness, we students have now adjusted to life at sea. We have already completed the first two super stations, which are places where we stop the ship to gather many types of data at once. We will be visiting the last station on our way back home. All of us have learned to operate together as a crew and as a team. We are now all at the point where we can enjoy our watches and perform to our fullest extent without the difficulties of seasickness and lack of knowledge of the ship. We are pleased to say that the kids that have been really troubled are now gaining their sea legs! We are also getting used to the different routines on the Cramer, such as: watch times at all hours of the night, strange mealtimes, performing boat checks, working in the Galley and Engine Room and more. Some interesting/neat things we have seen so far have been…
.. A cold front moving in with clouds resembling an avalanche
.. Atlantic white-sided dolphins chasing/playing off the bow while swimming through bioluminescent organisms around 3 a.m.
.. Lightning storms on the horizon
.. Clarity of skies revealing the Milky Way at night
.. Over 10 foot waves early in the morning
.. Sunrise on a perfect dawn watch morning
While these are just a few of the amazing moments we have shared so far, we hope that this journal is enough to keep any friends’ or relatives’ interests sated for the moment, or at least until tomorrow’s journal!

Thanks and until next time!

The Cramer’s Noon position today was 40° 40.2’ N, 70° 39.0’ W. The weather is warm, fairly clear, with a few Cirrostratus clouds in the horizon, and a nice breeze blowing from the Southwest.

This morning, the dawn watch spotted a pod of Atlantic White-Sided Dolphins racing with the bow of the ship and trying to catch some fish. The “A” watch then deployed the first oceanographic superstation with the Neuston net, the carousel, Shipek grab, Secchi disk, and a phytoplankton net.

Yesterday, the crew went through all the emergency drills to prepare for the very unlikely event of an emergency. As we left anchor in Vineyard Sound, a bunch of the students started feeling seasick, and continued to be so throughout the day. Luckily, most of us who were sick are now much better thanks to the care of the crew and the delicious food from the galley.

We’re now letting the wind carry us out towards the continental slope and the deep waters. Since the wind is so much in our favor at the moment, we will take advantage of it to sail out farther and then make some of the scientific deployments on the way back.
