It seems time for me to submit a dispatch to bring you up to date on the expedition itself. Gene and Ingrid have done a great job with their dispatches, so you have a pretty good idea of all that has been going on these past several weeks.
The high enthusiasm and eager anticipation that accompanied the arrival of the submersible in Wellington have become somewhat blunted as the days of delay have fallen one after another into what seems like weeks. We finally were able to set sail for Kaikoura and to complete several successful dives, the deepest to nearly 1800 feet (550 meters) along the edge of the strikingly sculptured Kaikoura Canyon.
That
last dive created yet another technical problem, this one to the pair of very
high intensity lights (HMI
lights) that are necessary for achieving the maximum quality images on the
digital video camera. The sub crew were able to repair the lights overnight,
so we were ready to go full bore in the morning. The first dive was scheduled
to 1000 feet so that our camera operator, Mike deGruy, could finish his certification
and be prepared for the all those deep dives to follow.
Poseidon
had other plans, however. A huge storm was raging far out to sea in the Pacific
to the east of Kaikoura. Even though the weather was gorgeous here, the big
swells were rolling in from the northeast, up to 2-3 meters high (6-9.5 ft).
Normally, seas of that size would not bother a research ship setting exploratory
trawls or other instruments, but it is a different situation when you have to
launch and retrieve a submersible covered with delicate camera gear. The rolling
and pitching of the ship can be a bit violent. Once the sub is raised off the
deck by a single cable suspended from the towering A-frame,
it becomes a 4-ton wrecking ball, only it would wreck itself by slamming against
the A-frame and ship. Of course, we always attach strong tag-lines
(guide ropes) every time we launch and retrieve, but in high seas the forces
are simply too great to control.
While
I concentrated on the safety of the sub and its external instrumentation in
the preceding paragraph, we perhaps should not forget what the wrecking-ball
effect might have on the pilot as well! Finally, before we launch the sub, we
must do everything we can to determine what the sea conditions will be at the
anticipated time of recovery. To launch in deteriorating sea conditions would
certainly be dangerous and irresponsible.
The high sea conditions have persisted for five days, and that has dealt a very serious blow to both our research objectives and to the filming requirements. I must say that everyone remains quite civil, but there is no mistaking the palpable undercurrent of utter frustration, the sense of helplessness against the forces of Nature and the immutable ticking of the clock as our allotted days slip by.
Nonetheless, I also sense, and very much feel so myself, that all the different crews, scientists, sub, film, ship, still believe in the expedition and in the potential of achieving our objectives. What a great team of professionals we have been privileged to assemble! I want to introduce some of the members of our team, but rather than my spilling the beans from an observer's point of view, I have asked them to write their own dispatches to tell you a little about themselves and about their participation in this unique and fascinating expedition. Their dispatches will appear over the next several days, interspersed with the latest information on the progress of the expedition.
Greetings,
Clyde
