The NR-1 comes in close to take up tow once again. You can
see the tow and compressed air lines both laid out on deck.

Ready for a busy day
More dives in the open ocean
Mmm! Bar-B-Que |
Up for Air
The NR-1 broke the surface this morning to fill up their
compressed air tanks (used for blowing their ballast tanks) and for scientific
equipment repairs. The day started with another open-ocean dive to re-open
the shutters on the Laser Line Scanner. At this time, they are permanently
open and should not cause any more problems. The storage of Laser images
was the next obstacle to mount. The jaz drive for the data storage was fried
by what they believe to be a faulty power supply. Improvising, the scientists
borrowed a power source from the ship's crew and took an internal jaz drive
from one of the lab computers on the Chouest. They hope that this will suffice.
Having removed a noisy pre-amplifier from the sound loop, the X-Star continues
to provide good sub-bottom data.
While the NR-1 was being re-fueled with compressed air,
the scientists got a short break from the sub. They got the chance to take
a shower and eat a real lunch. There is no place to shower on the NR-1 and
remember it is frozen cuisine all the time.
They are now again on the ocean floor at GC234, TAMU site
#9. They are preparing for their first mosaic. Hopefully, the new jaz drive
set-up will be amenable to their plans.
