Lost City (NUMA Files 5)

He handed the phone to his wife. Gamay Morgan-Trout was an attractive woman, not gorgeous or overly sexy, but appealing to most men. She had a flashing smile with a slight gap in her upper teeth like the model-actress Lauren Hutton. She was tall, five feet ten, and 135 pounds, slim for her height. Her hair, which was long and generally worn swirled, was dark red, the reason her father, a wine connoisseur, had named her after the grape of Beaujolais.

More open and vivacious than her husband, she worked well with men, a talent that went back to her tomboy days in Wisconsin. Her father was a successful developer who had encouraged her to compete with men, teaching her to sail and shoot skeet. She was an expert diver and marksman.

Gamay listened for a moment, and then said, "We'll be right over."

Hanging up, she said, "Dr. Osborne has asked us to come by the MBL. He says it's urgent."

"Everything is urgent to Sam," Paul said.

"Now, now. You needn't be snide just because he wanted to talk to me."

"I don't have a snide bone in my body," Paul said, linking arms with Gamay.

He bid good-bye to his colleague in the Submergence Lab and he and Gamay set off along Water Street. A few minutes later, they were climbing the wide stone steps at the Lillie Research Building, where they went through an arched doorway into a quiet lobby.

Dr. Osborne was waiting for them just inside. He pumped Paul's hand and embraced Gamay, whom he'd had as a student when she was studying marine biology at the Scripps Institute of Oceanography in California. Osborne was in his mid-fifties, and his receding, curly white hair seemed to be slipping off the back of his skull. He had a big-boned physique and large workman's hands that looked more suitable for handling a pickax than the delicate strands of marine vegetation that were his specialty.

"Thanks for coming over," he said. "I hope that This is no imposition."

"None at all," Gamay said sweetly. "Always a pleasure to see you."

"You may not think so when you hear what I have to tell you," Osborne said with an enigmatic smile.

Without further explanation, he led them to his office. Although the MBL was known all over the world for its research facilities and library, the Lillie Building lab was an unprepossessing place. Exposed pipes ran along the ceilings, the doors lining the hallways were of dark wood with pebbled glass panels, and in general it looked exactly like what it was, a venerable old lab building.

Osborne ushered the Trouts into his office. Gamay had remembered Osborne as fanatically neat and organized, bordering on the anal, and she saw that he hadn't changed. Where many professors of his stature surrounded themselves with piles of paper and reports, his office consisted of a computer table and chair and a couple of folding chairs for visitors. His only luxury was a tea maker, which he had picked up in Japan.

He poured three cups of green tea and after a brief exchange of pleasantries, he said, "Pardon me for being so brusque, but time is short, so I'll get right to the point." He leaned back in his chair, tented his fingers and said to Gamay, "As a marine biologist, you're acquainted with Caulerpa taxi folia

Gamay had received a degree in marine archaeology from the University of North Carolina before changing her field of interest and enrolling at Scripps, where she'd attained a doctorate in marine biology. Gamay smiled inwardly as she remembered being a student in Osborne's class. He typically asked questions in the form of a statement. "Caulerpa is an alga that's native to the tropics, although it's often seen in home aquariums."

"Correct. And you know that the cold-water strain that thrives so well in aquaria has become a major problem in certain coastal areas?" Gamay nodded. "Killer seaweed. It's destroyed large expanses of the seabed in the Mediterranean and has spread to other places as well. It's a strain of a tropical alga. Tropical algae don't normally live in cold water, but this strain has adapted. It could spread anywhere in the world."

Osborne turned to Paul. "The weed we're talking about was inadvertently released into the water beneath the Oceanographic Museum of Monaco in 1984. Since then it has spread to thirty thousand hectares in the coastal floor off six Mediterranean countries, and it's a problem off Australia and San Diego. It spreads like wildfire. The problem goes beyond speed. The Caulerpa colonies are extremely invasive The weed spreads out with runners and forms a dense green carpet that crowds out other flora and fauna, depriving plants and animals of sunlight and oxygen. Its presence destroys the base of the marine food web, damages native species with devastating consequences for ecosystems."

"Isn't there any way to fight this stuff?"

"In San Diego, they've had some success using tarpaulins to quarantine patches of weed, while pumping chlorine into the water and the mud that anchors the plants. This technique would be useless with a widespread infestation. There has been an effort to educate aquarium dealers who sell Caulerpa or deal in rocks that might be contaminated with organisms."

"No natural enemies?" Trout said.

"Its defense mechanisms are amazingly complex. The weed contains toxins that deter herbivores. It does not die back in winter."

"Sounds like a real monster," Trout said.

"Oh it is. It is. A tiny fragment can start a new colony. Its only weakness is that it can't reproduce sexually, like its wild relatives. But think what might happen if it were to disperse eggs over long distances." /

"Not a pleasant thought," Gamay said. "It could become unstoppable."

Osborne turned to Paul. "As an ocean geologist, you're familiar with the area of the Lost City?"

Trout was glad to get out of the realm of biology and into his area of expertise. "It's an area of hydrothermal vents along the Atlantic Massif. The material spewing from the sea bottom has built up tall mineral towers that resemble skyscrapers, hence the name. I've read the research on it. Fascinating stuff. I'd like to get out there sometime."

"You may soon get your chance," Osborne said.

Paul and Gamay exchanged puzzled glances.

Osborne chuckled, noting their befuddled expressions. "Perhaps you'd better come with me," he said. They left the office and after several twists and turns found themselves in a small laboratory. Osborne went over to a padlocked metal storage cabinet. He unlocked the door with a key hung from his belt and extracted a cylindrical glass phial about twelve inches tall and six inches in diameter. The top was sealed tight. He placed the phial on the table under a lab light. The container seemed to be filled from top to bottom with a thick grayish-green substance.
