After five days in North Carolina we have recovered all of the 80 stations. The stations have been recording for one month along two profiles. Now we are downloading the data at the instrument center at the East Carolina University in Greenville. The last step is getting the equipment ready for shipping back to PASSCAL in New Mexico.
Beatrice (Bix), Dan and Ana working onsite at the first station recovered. Bix and Ana are checking the parameters of the Reftek with the CLIE, and Dan is saving the GPS waypoint of the recovery site.
Yanjun working on one of the stations recovered on the north line. He is performing a check with the CLIE to see the number of events recorded, the data stored on the disks and stopping the acquisition. He also checks all 3 channels on the L28 sensor. Once the acquisition has been stopped, the sensor can be pulled and the station is taken back to the instrument center.

We experienced wonderful weather during the past week working in North Carolina. The scenic countryside is filled with tobacco fields, cotton fields, and other crops. One lucky recovery team started the first day on Kitty Hawk Beach demobilizing site 101.

By Galileo’s careful hand, sunspot details are exquisite,
Through eye of forehead, eye of mind beholds what body can not visit.
If only he could see the sights now rendered from Earth’s outer space,
Ultraviolet sunscapes – Oh, to see his raptured face!
High above Earth’s atmosphere, IRIS probes the edges of our star,
A telescope in orbit, through its lenses, we see far.
Six thousand Kelvin screams the surface, roiling plasma, like hellish seas,
Hotter still, the sun’s corona: millions of degrees!
Mysterious, this source of heat that drives the solar wind our way …
High-speed jets, coronal loops and nanoflares may be at play.
What a thrill to gaze through space with spectrographic eyes,
Fueled by human wonder and a zeal to probe the skies.

There once was the Langseth, a ship
Over wave and trough did she skip.
Many instruments aboard
To always record
Depth, gravity, mag – every blip.
There once was the Langseth, a vessel
Where in their bunks scientists nestled.
‘Til called to their shifts
Their heads they must lift
For with errors and logs they must wrestle.
There once was the Langseth, a boat
On her airguns the crew they would dote.
Oft while in a turn
Guns were brought up astern
To ensure best acoustical note.
There once was the Langseth, seacraft.
Where we launched XBTs down a shaft.
With each probe descent
To the lab data went
So that temperature-depth could be graphed.
There once was the Langseth, a fine tub!
Where the galley crew made us good grub.
But when seas ran high
Up in knots stomachs tied
And to keep the food down, there’s the rub.
There once was the Langseth, fair barge.
To collect seismic data her charge.
Streamer 8-km long
And four gun strings strong
She’s the fleet’s seismic dreadnaught at large!

Three days ago, at approximately 2130, we recovered our final OBS and started our 36-hour transit back to Narragansett, RI. We began docking procedures at Senesco Marine LLC at around 1300 yesterday and were all tied up by 1400. After the lines were clear, both watches performed some preliminary breakdown of the OBS equipment to help stage it for demobilization this morning. It was impressive how fluidly we took and executed directions after a month of working together. It was clear that the trip had bonded us as a team. After everything was done, the group headed out to enjoy our first night on land, which, as anyone whose been on a ship for an extended period will tell you, is just an incredible feeling. One of the eeriest moments, however, was all of a sudden being surrounded by people besides those you’ve been on the trip with. Also, the “dock rock” is an interesting experience.
This morning, after a wonderful, final breakfast made by our steward, Mike Duffy, we packed up the final gear and the crew began lifting it off the boat, staging it on the pier. All that’s left now is to clean up my stateroom, pack up all my stuff, and head on home. This cruise has been both a great scientific and personal learning experience and I am happy to have worked with these crewmembers, techs, researchers, and students. The lab seems so empty now, as I write this post, and there’s a part of me that is sad that this adventure is ending regardless of how excited I am to get back to life on land.
Anyways, time for me to go. For those who are interested in the data we’ve collected on this cruise, look out for information concerning workshops on data access and processing in the near future.
