Trojan Odyssey

She glanced at her compass and made a slight turn to the left, kicking her fins while clasping her hands behind and under her twin air tanks to reduce water resistance. Wearing the bulky suit and AGA Mark II full face mask made it seem easier to walk on the bottom than swim over it, but the often sharp and uneven surface of the coral made that nearly impossible.

Her physical contours and facial features were shrouded by the baggy dry suit and full head mask. The only clues to her beauty were the exquisite gray eyes gazing through the face mask lens and a wisp of red hair that showed on her forehead.

Summer loved the sea and diving through its void. Every dive was a new adventure through an unknown world. She often imagined herself as a mermaid with salt water in her veins. Urged by her mother, she had studied ocean sciences. A top student, she graduated from the Scripps Institute of Oceanography, where she had received her master's degree in biological oceanography. At the same time, her twin brother, Dirk, had achieved his degree in ocean engineering at Florida Atlantic University.

Soon after they returned to their home in Hawaii, they were informed by their dying mother that the father they never knew was the special projects director for the National Underwater and Marine Agency in Washington, D.C. Their mother had never talked about him until she was lying on her deathbed. Only then did she describe their love and why she let him believe that she had died in an underwater earthquake twenty-three years before. Badly injured and disfigured, she thought it best that he live his life unencumbered, without her. Several months later she gave birth to twins. In memory of her undying love she had named Summer after herself, and Dirk after his father.

After her funeral, Dirk and Summer flew to Washington to meet Pitt Sr. for the first time. Their sudden appearance came as a total shock to him. Stu

Embracing the family he never knew he had, he immediately moved them into the old aircraft hangar where he lived with his huge classic car collection. When he was told that their mother had insisted they follow in his path and become educated in the ocean sciences, he orchestrated their employment with NUMA.

Now, after two years of working on ocean projects around the world, she and her brother had embarked on a unique journey to investigate and gather data on the strange toxic contamination that was killing the fragile sea life on Navidad Bank and other reefs throughout the Caribbean.

Most parts of the reef system still teemed with healthy fish and coral. Brightly hued snappers mingled with huge parrot fish and groupers while little iridescent yellow-and-purple tropical fish darted around tiny brown-and-red sea horses. Moray eels looking fierce with their heads protruding out of holes in the coral, opened and closed their jaws menacingly, waiting to sink their needle teeth into a meal. Summer knew they looked frightening only because that was their method of breathing since they did not have a set of gills on the back of their necks. They seldom attacked humans unless they were antagonized. To be bitten by a moray eel, one almost had to place a hand in its mouth.

A shadow crossed above a sandy gap in the coral and she looked up, half expecting to see the same shark returning for a closer look, but it was a flight of five spotted eagle rays. One peeled off the formation like an aircraft and cruised around Summer, staring curiously before swooping upward and rejoining the others.

After traveling another forty yards she slipped over a formation of horny gorgonian coral and came within view of a shipwreck. A huge five-foot barracuda hovered over the debris, staring out of cold, black beady eyes at all that took place in its domain.

The steamship Vandalia was driven onto Navidad Bank in 1876 during a fierce hurricane. Of her one hundred and eighty passengers and thirty crewmen, none survived. Listed by Lloyd's of London as lost without a trace, her fate remained a mystery until sport divers discovered her coral-encrusted remains in 1982. There was little left to distinguish Vandalia as a shipwreck. A hundred and thirty years on, the bank had covered her with anywhere from one to three feet of sea life and coral. The only obvious signs of what was once a proud ship were the boilers and engines that still protruded from the twisted carcass and exposed ribs. Most of the wood was gone, long rotted away by the salt water or eaten by critters of the sea that consumed anything organic.

Built for the West Indies Packet Company in 1864, Vandalia was 320 feet from the tip of her bow to the jack staff on her stern, with a 42-foot beam and accommodations for 250 passengers and three holds for a large amount of cargo. She sailed between Liverpool and Panama, where she unloaded her passengers and cargo for the rail trip to the Pacific side of the isthmus where they boarded steamers for the rest of the journey to California.

Very few divers had salvaged artifacts from Vandalia. She was difficult to find in her camouflaged position amid the coral. Little was left of the ship after being crushed that horrible night by the mountainous waves of the hurricane that caught her in the open sea before she could reach the safety of the Dominican Republic or nearby Virgin Islands.

Summer roamed over the old wreck, carried by a mild current, looking down and trying to picture the people who had once trod her decks. She sensed a spiritual sensation. It was as if she was flying over a haunted graveyard whose inhabitants were speaking to her from the past.

She kept a wary eye on the great barracuda that hung motionless in the water. Food was no problem for the ferocious-looking fish. There was enough sea life living in and around the old Vandalia to fill an encyclopedia on marine ichthyology.

Forcing her mind from visions of the tragedy, she swam warily around the barracuda that never took a beady eye off her. A safe distance away, she paused to check the air left in her tanks on the pressure gauge, mark her position on a Global Positioning System satellite minicomputer, eye the compass needle in relationship to the underwater habitat where she and her brother were living while studying the reef and note the reading on her bottom timer. She felt slightly buoyant and neutralized by venting a bit of air from her back-mounted buoyancy compensator.

Swimming another hundred yards, she saw the bright colors fading and the coral turning colorless. The farther she swam the more the sponges became glazed and diseased, until they died and ceased to exist. The visibility of the water also dropped drastically, until she could see no farther than the extended tip of her hand and fingers.

She felt as if she had entered a dense fog. It was a phenomenon, known as the mysterious "brown crud," that had appeared throughout the Caribbean. The water near the surface was an eerie brown mass that fishermen described as looking like sewage. Until now, no one knew exactly what caused the crud or what triggered it. Ocean scientists thought it was associated with a type of algae, but had yet to prove it.

Strangely, the crud did not appear to kill the fish, like its notorious cousin, the red tide. They avoided contact with the worst of the toxic effects, but soon began to starve after losing their feeding grounds and shelter in the process. Summer noticed that the usually brilliant sea anemone, with their arms extended to feed in the current, also seemed hard hit by the weird invader to their realm. Her immediate project was simply to take a few preliminary samples. Recording the dead zone on Navidad Bank with cameras and chemical analysis instruments to detect and measure its composition would come later, in the hope of eventually finding countermeasures to eradicate it.
