Reflections

With our stations complete, we headed home a bit early on Saturday, and with the approaching nor’easter on Mother’s Day, it was probably a good decision.  I thoroughly enjoyed my experience and value the efforts, hard-work, professionalism and teamwork that make an undertaking of such enormity a valued and fun endeavor.  The camaraderie of the team will be forever cherished.

We came back through the Cape Cod Canal late in the evening, on our return to Newport, RI.  We spotted joggers with head lamps running along the path of the canal. Perhaps a local road race?

It was interesting feeling in my kitchen rocking and rolling all day Sunday …. dock rock or kitchen rock???  That was a fun sensation!!

It was nice to see my students this morning, Monday, all welcoming me home and curious about my trip.  On Sunday, I had prepared a slide-show of many of my photos and projected my blog on the “Smartboard” to share with my classes.  They had a wide range of questions from what did I eat, was I seasick, what fish did we catch, did you dissect any fish, did you see any whales, how old do you have to be to go out on the ship, to what will the scientists do with the samples that were saved. They were impressed with my pictures of the goosefish, (who wouldn’t be impressed with such a fish!) and laughed at how the scientist I worked closely with nicknamed me a “Fish Wrangler” as I had caught, in midair,  some slippery, squirming, flip-flopping Red Fish as they had managed an attempted escape off the scale when a big wave hit.  I’ll wear that tag with pride!

Thank you to NOAA and their staff that prepared me for the journey.  Thank you to all the wonderful people I met on the ship.  A “Teacher at Sea” is a monicker of which I will be always proud … as well as “Fish Wrangler!”

Science and Technology Log
We left Half Moon Bay at 0700 (7:00 am) to survey line 10. We traveled out to about 30 miles offshore then deployed the Tucker trawl.

Tucker Trawl

Tucker Trawl

When the team deploys the Tucker trawl the goal is to collect krill. They are relying on the echo‐sounder to determine where the krill are located in the water column. The echo‐sounder sends out sound waves that bounce off objects in the water and works much like a sophisticated fish finder. Dolphins hunt for their prey in much the same way. A computer connected to the echo‐sounder is used to display the image of the water column as the sound waves travel back to the boat. By reading the colors on the screen the team can determine the depth of krill.

The scientists send weights (called messengers) down a cable that is attached to the Tucker trawl as it is towed behind the boat. Once the messenger reaches the end of the line where the net is located, it triggers one of the three nets to close. Triggering the nets this way allows for the researchers to sample zooplankton at three different depths.
