Around the World Submerged (36 page)

2339 As we make this observation, our sense of well-being is shattered again: the active sonar is reported out of commission; cause not yet determined. It is the report I have been dreading most. We still have thousands of miles to travel through not-too-well-sounded waters. Without a fathometer, it is essential that we keep our active sonar in commission.

Thursday, 7 April 1960 0050 A thorough check of the active sonar has revealed that a tube has failed from long continuous usage. With a new tube installed, the equipment is functioning as well as ever, and Will Adams, Bob Bulmer and I are greatly relieved. Bob, having officially relieved Will as Navigator when we left Lombok behind, finally feels light hearted enough to accuse his mentor of having deliberately caused the sonar failure to take place at this precise moment. Will grins. “Of course I did,” he says. At which point I don’t know whether to believe these clowns or not.

Sunday, 10 April 1960 0000 Ventilation secured after a thorough sweep-out of the atmosphere of the ship. One of the requirements of the cruise is to conduct a sealed-ship test under controlled conditions for observation of certain phenomena. Our time with a sealed atmosphere will not approach that of
Seawolf
in 1958, mainly because of the expense of all that oxygen, nor does it need to, so far as this test is concerned. But since we are a brand-new ship, this is one of the things we need to accomplish merely to develop our own techniques and limiting factors.

Until now, except for short periods for testing of our equipment, it had been our practice to come to periscope depth
every night for about an hour, and run up the ventilation pipe for a sweep-out of the bad air and replacement with fresh sea air. Life under these conditions had its rigorous aspects. Little by little, during the day, the oxygen content of our atmosphere was reduced as the 183 men on board
Triton
slowly consumed it. Toward the end of the day, it usually had become oppressively low.

We were not concerned about the accumulation of carbon dioxide, for one or more of the carbon-dioxide-removal apparatuses was run continuously and we had no difficulty in keeping the carbon-dioxide content under control. The average consumption of oxygen by active persons, however, is just under a cubic foot of oxygen per man per hour, and a very close correlation was immediately found to exist between our oxygen consumption and the days of the week. On Sundays, when there was very little going on beyond normal ship cruising routine, the oxygen consumption per man approximated seven-tenths of a cubic foot per hour. Friday was Field Day, with all hands up and turning to, and the average consumption this day was always about one cubic foot per hour. As a consequence, one of the disadvantages of our Friday Field Days was the labored breathing which afflicted all hands the last few hours prior to running up the snorkel pipe.

We discovered other phenomena, too. For example, increasing the pressure of the ship’s internal atmosphere had no effect upon the percentage of oxygen it contained, but it did have an effect upon the total amount of oxygen in each cubic foot of atmosphere. Thus, deliberately increasing the air pressure in the ship by a pound or so per square inch greatly improved the ability of our laboring lungs to draw in oxygen, and consequently everyone felt better. The difficulty with this scheme was that as soon as we began ventilating to the atmosphere, the pressure would reduce to normal. If we luxuriated in hyper-pressure atmosphere for too long a period, some of us might temporarily be exposed to an atmosphere below
the minimum allowed oxygen content before our ventilation blowers had managed to sweep out the bad air.

It is remarkable how much stability the human body requires within the wide range of the possible conditions of nature. Ideally, man should be in a temperature of around 70°; by various stratagems, he is able to exist over a temperature range of perhaps 120°, centered on the 70° midpoint. But temperatures in nature can go down to a minus 459° F—which it does in outer space—or up into the thousands of degrees.

Man is acclimated to twenty-one percent of oxygen in the air at normal pressure. He suffers acutely if the oxygen percentage drops only a few points, to seventeen percent, for example, or rises much above twenty-one percent. At the time that we in
Triton
began to feel distressed, we would have consumed only one-sixth of the available oxygen in the atmosphere of the ship. Were the oxygen percentage to rise above the norm of twenty-one, we should probably experience most of the effects of ordinary intoxication.

There was really nothing unusual in these “discoveries” which we were making; submariners have known and applied the principles for years. But there is no substitute for experience, which opens many new avenues of inquiry.

For example, there was the question whether gradual oxygen reduction each day for a prolonged period would have any damaging consequences on us. The effects of depriving the human body of oxygen all at once to an excessive degree are well known. But what about minor deprivation for many days? No observable deleterious effects have been noted, but many highly qualified medical people have recently been devoting considerable research to this question. The problem ranges from the physical to the psychological, from an environment of oxygen deficiency to one in which the entire atmosphere is mechanically controlled and stabilized at some optimum point.

From the Log:

The Medical Research Laboratory in New London has been pursuing this particular project for a long time, the first announced test being Operation Hideout in the mothballed submarine
Haddock
in 1953. Doctors Ben Weybrew and Jim Stark have been discussing the sealed-atmosphere test for several days, and finally have proposed a procedure. We will remain sealed for approximately 2 weeks, running various physical and psychological tests among selected volunteers from the crew. Somewhere during the mid-point of this period we will put out the smoking lamp for an extended time. Careful checking of all factors will continue for several more days before terminating the study.

The purpose of the no-smoking test was partly psychological, but there was a question of atmospheric research, too. Smoking, nuclear submariners had discovered, was their only source of carbon monoxide. In a completely sealed atmosphere, accumulation of carbon monoxide could not be permitted because of its deadly brain-damaging tendency. Expensive equipment had been devised and installed to convert it into carbon dioxide, so that it might be “scrubbed” from our atmosphere along with the carbon dioxide exhaled from our lungs.

One of the questions raised was whether or not this equipment was worth the cost; or whether it would be better to prohibit smoking in a completely sealed atmosphere, instead of going to the added expense and trouble of installing the carbon-monoxide removal apparatus purely because of the psychological satisfaction that some men got out of smoking. All this, of course, has a direct bearing on the endurance of submarines at sea—their ability to cope with the various problems they would undoubtedly encounter, and the efficiency with which they might be expected to operate under various severe conditions. The data that we were helping to gather would become available to our first space pioneers also.

Everyone on board was determined to go through with the test in good heart and spirit, but as the dread day for putting out the smoking lamp approached, various reactions were noticeable among crew members. The nonsmokers were lording it over the others, describing with great relish how the test would have no effect whatsoever on them, and there was an aura of apprehension among the habitual smokers. Even before we put the smoking lamp out, the witticisms had an edge to them, and some of the protestations that “smoking don’t mean that much to me” developed a noticeably defensive tinge.

One saving feature in the eyes of many was the fact that both doctors on board, Commander Jim Stark, who dabbled in psychology, and Dr. Ben Weybrew, professional psychologist attached to the Medical Research Laboratory, were themselves inveterate smokers. Weybrew created quite a stir, therefore, the evening before the test was scheduled to begin, when he casually tossed his pipe into the garbage ejection chute. He, at least, was ready to make his sacrifice for science, and it was said that he whistled happily as he prepared the charts and the graphs he would draw as a result of our sufferings.

One thing we did notice as soon as we sealed up the ship: maintaining our atmosphere at a common standard level of oxygen content was a far more comfortable way to exist. Among other things, the air conditioners had less work to do; once the humidity was brought to the optimum level, it was easy to maintain. Previously, and by contrast, the fresh air drawn in from just a foot or two above the surface of the tropical seas was extremely humid and salty, dampening the entire ship for a few hours until the air-conditioning machinery had caught up with it again. To illustrate a second advantage: perhaps I personally had become accustomed to the daily deprivation of oxygen, or perhaps I had simply been unaware of my reduced efficiency. At any rate, I found myself more alert, more alive,
and less tired when breathing the artificial atmosphere than when we were taking daily snorts of fresh air.

Everyone on board, I believe, had a somewhat similar reaction. We settled down quickly to the pleasantest period of the entire trip and, deeply submerged, crossed the Indian Ocean without physical contact with the outside in any way.

The Indian Ocean, by the way, is to the US sailor one of the least-known oceans. Yet it was one of the better-known waters of Renaissance days. According to the chart, it is uniformly deep, its bottom scarred by relatively few of the peaks and valleys familiar to the Atlantic and Pacific. In color, the water seems somewhat bluer, more transparent, with less marine life and less natural or artificial flotsam and jetsam.

During the war, the southern part of the Indian Ocean was especially active with German surface raiders and the British task forces set out to intercept them; and there were German, Japanese, British, and Dutch submarines on patrol in the area as well. So far as America is concerned, however, it is one of the oceans we still have to discover. Now that knowledge of the sea is of greater importance to our country than ever before, it is probably time we learned some of the intimate details of this great and unexplored body of water.

Monday, 11 April 1960 A message from ComSubPac relays information from ComSubLant announcing prospective promotion of Chief Petty Officers Bennett, Blair, Hampson, Hardman and Loveland to the rank of Ensign, and of the following First-Class Petty Officers to the rate of Chief Petty Officer: Hoke, Meaders, Lehman, Mather, Pion, Stott, Bloomingdale, Flasco, Fickel and Tambling. There is jubilation among the lucky advancement winners and good sportsmanship among the others. But this can’t be the entire promotion list, since examinations for all rates down to Third Class were held before departure. More information should be forthcoming soon. Five Ensigns and ten Chief Petty Officers is a tremendous haul for any single ship, particularly one
with a crew of only 159 enlisted men. It is a tribute to the overall capability of our crew, and to the hard effort of the men themselves. The fact that their tests were taken during an extremely heavy watch-standing schedule, to which was added strenuous overtime preparation for an unusual cruise, adds to the accomplishment.

The opportunity for hazing some of the lucky ones is too good to be missed. One by one they are called before me to be asked, in a grave voice, “What have you done to cause ComSubLant to send a message to us about your actions?” The look of incredulity on the faces of the first ones to arrive was real enough, but all ships have a sort of extra-sensory communication among the crew, and I doubt if the last few were particularly perturbed by my feigned severity.

Tuesday, 12 April 1960 Seventh babygram—sixth girl, 9 1bs., born 8 April; father, Bruce F. Gaudet, IC3. Both mother and baby fine. Poor Gaudet had been getting a little worried, but he feels fine now.

Six days a week all during our cruise, the
Triton Eagle
had faithfully come out in the early morning hours, composed directly on the duplicating machine paper by editor in chief Harold J. Marley and laboriously run off on the printing machine, with the ship’s office swept up afterward, by Audley R. Wilson, Radarman First Class, who comprised the entire staff of the paper outside of the editor. Except for one memorable day when Editor Marley took all his news from a three-year-old edition of the New York
Times
(detected by very few people, surprisingly), we had managed to get up-to-date news. Every day or so I managed to come up with a column of some kind for the paper—either “The Skipper’s Corner” or another, which I fondly hoped was a humor column, supposedly written by an unidentified person named Buck. Buck was an unregenerated sailor, butt of all jokes, apt only in hiding from
work and the “
OM
” (myself, the “Old Man”). Theoretically, nobody knew that Buck was the “
OM
” himself.

There was a moment of concern early in the game when I realized that Lawrence W. Beckhaus might equate
Triton
’s Buck column with a similar one in
Salamonie’
s
Bunker Gazette,
but a sharp sally from Buck, in which Larry was admonished to keep his mouth shut, had, I supposed, the desired result.

Had one never experienced it before, the large share of our daily lives occupied by this little two-page newspaper might have appeared surprising. To me it was not, for I had seen the same thing before on long, uninterrupted cruises. The moment the ship gets to port, however, there is no further interest, and the ship’s newspaper may as well cease publication until you are once again at sea.

The highest point of the
Triton Eagle’
s journalistic achievement was probably reached during our traverse of the Indian Ocean, when it published daily reports on an extended controversy involving a mythical “two-gauge goose gun.” Tom Thamm and Chief Petty Officers Loveland and Blair were arraigned on opposite sides of the argument, which ran for several issues, and everyone had a lot of fun with it.
