As he answered, Dick characteristically chose his words carefully. “We’ve been slowly losing sensitivity with the fathometer,” he said, “and I’ve started checking into it. The strength of the echo is becoming noticeably weaker. I worked on it for a couple of hours last night, but it is still weaker than it should be, even though we seemed to have been able to make some improvement in it. We’re getting only a faint echo, and it could go completely out of commission at any time.”
“Where do you think the trouble is?” I asked. “Is it in the transmitter head, do you think, or the transmitting or receiving section of the set itself?”
“Dunno yet, Captain,” he said. “As far as we can tell, the outgoing signal is about the same strength as ever, but the return signal seems to be weaker. Maybe we’ll find something wrong with the receiver section, and if we can get the right parts, we should have it back in commission soon.”
“Keep me advised, Dick,” I said. “The fathometer is a mighty important instrument for this cruise, especially since we are passing over waters that are basically uncharted.”
Dick tried another twisted half-grin. “I know that, sir,” he said. “‘Whitey’ Rubb is in there helping us with his electronic technicians. Maybe that will speed up the process of figuring out what’s wrong with it.”
After Dick left, I sat for a long moment. Now there were two problems to ponder. Shallow water areas near most of the big land masses of the world are well charted these days, and a surface ship has generally little difficulty picking its way along an unfamiliar coast as long as it has the right chart. But nobody had ever gone to much trouble to make accurate charts of deep waters, the so-called “off-soundings” areas, which comprise ninety-nine percent of the oceans. Our unsuspected discovery of a new and previously uncharted mountain peak as we neared St. Peter and St. Paul’s Rocks a few days ago was a case in point. The chart of the South American coast showed a number of very shallow spots—just dots on the charts—where evidently some submerged mountain peaks had been discovered more or less by accident as ships passed overhead. Surface vessels had been passing over these peaks in perfect safety for centuries, their existence entirely unsuspected. But our situation in
Fortunately, an immediate decision on this, too, could be postponed for a little while. At the moment,
In the control room, Chief Sonarman George McDaniel, assisted by Sonarmen First Class Beckhaus and Kenneth (“Shorty”) Remillard, had already removed the cover from the fathometer console, and they were taking electrical measurements of the electronic equipment inside. The space where they had to work also happened to be the Diving Officer’s watch station. And Lieutenant George Sawyer, whose watch this was, appeared to be having a little difficulty staying out of their way.
One deck below and one compartment aft, in the air-control center, where the data supplied by
It was apparent that all these men, at least, fully shared my appreciation that our fathometer needed to be put back in commission quickly.
In the crew’s berthing compartment, just forward of the control room, I came upon Poole. In spite of Jim Stark’s warning, I was unprepared for what I saw, and was instantly shocked into concern.
Eyes half-closed, face swollen, Poole had risen to his forearms and knees and was quivering with obviously excruciating pains.
