Week 1 - The Transit
|
The Hole Truth – Catch
it Quick, it’s Superfast! |
10 July 2005 |
It’s been quite a memorable trip!! It took over an hour to drive from my home town of Romulus, NY, in the middle of the Finger Lakes region, to get to Rochester, NY, and just 10 minutes by plane to fly over Romulus on the way to Newark, NJ. I left my home at 10:00 AM and arrived at Panama City at around 8:30 PM (local time – they aren’t on Daylight Savings Time). Several of us on the plane were bound for the ship but we had to wait for another shipmate before being taken to the ship in a private car. We reached the ship at about 1:00 AM on the 11th…

I met and had coffee with Paula Weiss, IODP Curatorial Representative (and the Teacher at Sea mentor for this cruise), then went on a tour of the ship. After the tour I found my home for the next six weeks (in the operations office) and had my computer set up. The ship wasn’t going to sail for a few more days and there was a lot of work to do. A shipment of refrigerated and frozen cores and samples from the previous cruise had to be prepared and sent. I helped the technical staff repack the shipment and then finish packing and sealing the frozen and refrigerated samples with dry and blue ice. Other shipments also had to be off-loaded.
The transit to our first site, Site 1256D (first cored to a depth of 752 meters below seafloor in 2003 on ODP Leg 206), would take several days to complete – so there will be no cores until at least next Tuesday or Wednesday. There are science meetings each day at 10:00 AM, and various other meetings I am scheduled to attend.

At the science meeting/indoctrination
for all technicians and scientists, we went over
the objectives of the cruise, how to survive the
cruise, and cruise etiquette, as well as a briefing
by the computer staff. Safety training was held
at 1300 (1:00 PM); speakers included the captain,
ship’s doctor and second mate. We were taught
safety procedures and rules, and then given a tour
of a lifeboat.
After the safety meeting, there
was a technician meeting in the core lab to review
splitting techniques. The new technicians and I
were given the “IODP Core Lab Cookbook.” We
went through the procedures for processing the
core to insure its integrity in the labs and throughout
the testing process.
We left the pier at 1600 and started
through the Panama Canal. The first set of locks
were absolutely incredible! Everyone’s heard
of the Panama Canal, but it’s awesome to
actually go through it. There was a large cargo
carrier that went through all of the locks with
us. I can’t believe we both fit in the locks
at the same time. We left the first set of locks
at almost 1900. After the first set of locks came
Gatun Lake, and the ship didn’t even feel
like it was moving!!!
We came to the Centennial Bridge
at approximately 2130. Even with the top of the
ship’s derrick lowered, it appeared that
the ship just barely fit under the bridge. It began
to rain, a nice gentle warm rain! We reached the
last set of locks shortly thereafter. The rain
picked up a little. We reached the Bridge of the
Americas at about 0130. It was now raining pretty
hard. Just as with the first bridge, it looked
like we were in danger of hitting it, but we passed
through without incident.

Preparation for next week is underway;
everyone is getting ready for the first core. This
is the lull before the storm. The thin sections
from Leg 206 were in need of re-organization after
borrowed slides were returned, so they were placed
in numerical order and inventoried. The science
meeting was at 1000. We reviewed necessary shipboard
information, then had an overview of Leg 206, when
Hole 1256D was started. We then had brief introductions
to each of the labs.
I was invited to attend the operations pre-site meeting at 1400 with Damon Teagle, Co-Chief Scientist (UK); Susumu Umino, Co-Chief Scientist (Japan); Neil Banerjee, IODP Staff Scientist/Expedition Project Manager (USA); Kevin Grigar, IODP Operations Superintendent (USA); Florence Einaudi, Logging Staff Scientist (France); Akram Belghoul, Logging Trainee (France); Doug Wilson, Geophysicist (USA); and the TransOcean Drilling, Marine and Electrical Supervisors. During the meeting we were given
the drilling plan for this expedition and reviewed
objectives/expectations, methods and materials
for carrying out the plan. Some of the items discussed
were bit sizes, hole casing, core casing, and logging
of the hole (inserting special instruments into
the hole to take measurements such as temperature)

I visited the underway geophysics
lab at midnight and stayed until 0300 to watch
the start-up of the equipment. The IODP equipment
that keeps track of the ship’s position,
sea depth and seafloor magnetic properties are
housed and monitored there. A lot of earth science
in that room! While the ship is underway, these
features are being physically monitored. After
a nap and breakfast I helped the technicians move
some Leg 206 archive-half cores into the core
lab. They were moved from the storage refrigerator
so the scientists could examine them after the
morning science meeting. The cores came from Hole
1256D, the hole we are going to deepen. By
examining these cores, we will have an idea of what
to expect from the cores to come.
At the morning science meeting,
everyone with core sample requests was asked to
state the purpose of their request. This was done
to foster collaboration between the scientists.
The vast amount of geologic knowledge in that room
was amazing to me. Quite a bit of collaboration
had already occurred, and now more was to take
place.

At the science meeting Susumu Umino, Co-Chief Scientist (Japan), gave a talk on the ophiolites (uplifted ocean crust deposited on continental crust) of Oman. We were also given an update by Florence Enaudi, Logging Staff Scientist (France), on the logging that would take place after we arrived on site. During the logging of the hole, instruments will be lowered on a wireline through the drill pipe to take measurements and check the condition of the hole. The re-entry and logging are estimated to take two days. Logging is a very slow process.
At the core description meeting the scientists had a chance to look over the core and the core description sheets. With this knowledge they could now comment and make recommendations for the core description sheets for this cruise and for Expedition 312, which will take place this fall and be a continuation of Expedition 309. Everyone needs to do the descriptions in exactly the same way.
During my underway watch, the most fascinating part was watching the depth recorder. The transducer under the ship sends out a series of acoustic signals (sound waves) that are recorded after they bounce off of the ocean bottom. Even a novice can see a lot of ocean floor features! I was able to see horst and graben, trenches, seamounts, and other sudden changes in seafloor elevation.
