The Deep Range - Arthur C. Clarke [53]
“My—you do look pretty! If I was another squid, I’m sure I’d find you irresistible. Swing broadside a minute. Thanks. Talk about a Christmas tree! It’s the first time I’ve ever seen one making ten knots at six hundred fathoms.”
Franklin grinned and switched off the illuminations. This idea of Dr. Roberts’ was simple enough, but it remained to be seen if it would work. In the lightless abyss, many creatures carry constellations of luminous organs which they can switch on or off at will, and the giant squid, with its enormous eyes, is particularly sensitive to such lights. It uses them not only to lure its prey into its clutches, but also to attract its mates. If squids were as intelligent as they were supposed to be, thought Franklin, Percy would soon see through his disguise. It would be ironic, however, if a deep-diving sperm whale was deceived and he had an unwanted fight on his hands.
The rocky bottom was now only five hundred feet below, every detail of it clearly traced on the short-range sonar scanner. It looked like an unpromising place for a search; there might be countless caves here in which Percy could hide beyond all hope of detection. On the other hand, the whales had detected him—to their cost. And anything that Physeter can do, Franklin, told himself, my sub can do just as well.
“We’re in luck,” said Don. “The water’s as clear as I’ve ever seen it down here. As long as we don’t stir up any mud, we’ll be able to see a couple of hundred feet.”
That was important; Franklin’s luminous lures would be useless if the water was too turbid for them to be visible. He switched on the external TV camera, and quickly located the faint glow of Don’s starboard light, two hundred feet away. Yes, this was extremely good luck; it should simplify their task enormously.
Franklin tuned in to the nearest beacon and fixed his position with the utmost accuracy. To make doubly sure, he got Don to do the same, and they split the difference between them. Then, cruising slowly on parallel courses, they began their careful search of the sea bed.
It was unusual to find bare rock at such a depth, for the ocean bed is normally covered with a layer of mud and sediment hundreds or even thousands of feet thick. There must, Franklin decided, be powerful currents scouring this area clear—but there was certainly no current now, as his drift meter assured him. It was probably seasonal, and associated with the ten-thousand-foot-deeper cleft of the Miller Canyon, only five miles away.
Every few seconds, Franklin switched on his pattern of colored lights, then watched the screen eagerly to see if there was any response. Before long he had half a dozen fantastic deep-sea fish following him—nightmare creatures, two or three feet long, with enormous jaws and ridiculously attenuated feelers and tendrils trailing from their bodies. The lure of his lights apparently overcame their fear of his engine vibration, which was an encouraging sign. Though his speed quickly left them behind, they were continually replaced by new monsters, no two of which appeared to be exactly the same.
Franklin paid relatively little attention to the TV screen; the longer-range senses of the sonar, warning him of what lay in the thousand feet ahead of him, were more important. Not only had he to keep a look out for his quarry, but he had to avoid rocks and hillocks which might suddenly rear up in the track of the sub. He was doing only ten knots, which was slow enough, but it required all his concentration. Sometimes he felt as if he was flying at treetop height over hilly country in a thick fog.
They traveled five uneventful miles, then made a hairpin turn and came back on a parallel course. If they were doing nothing else, thought Franklin, at least they were producing a survey of this area in more detail than it had ever been mapped before. Both he and Don were operating with their recorders on, so that the profile of the sea bed beneath them was being automatically mapped.
“Whoever said this was an exciting life?” said Don when they made their
