wire drag
A fine diagram of a wire-drag operation. The wire is towed between two tugboats, suspended by buoys at a predisposed depth. When the cable snags on an obstruction and draws into a V, the buoys point to its location.

Wire dragging is an operation used to locate and/or reduce the navigational hazard of a sunken wreck, rock, or other obstruction.

LOST AT SEA:
A treatise on the management and ownership
of shipwrecks and shipwreck artifacts

by Michael C. Barnette

shipwreck Lillian

Somewhere out on the ocean, a ship is in distress. Tossed about by churning seas and brutal winds, the vessel struggles to stay afloat. Her crew puts forth a valiant effort while passengers, many incapacitated by waves of nausea spawned by the ever-moving deck underneath their feet, huddle together in fear. The hull is slowly breached, and seawater steadily invades the ship. As the blitzkrieg of flooding water rises to extinguish the boiler fires, the vessel loses all power. Cast in darkness and overwhelmed by the noise of the howling wind and crashing surf, the sea tears off sections of the crippled ship, carrying away numerous unfortunate souls. The end is near.

New Jersey scuba divers provide evidence of the identity of a popular New Jersey dive site


John Chatterton and the Horenberg knife
John Chatterton and the Horenberg
knife, the most tangible clue to the
identity of New Jersey's mystery U-boat.

In 1991, while checking out an obscure site known for hanging up fishing lines, I dropped down the anchor line only to find a virgin German U-boat. A wreck diver's fantasy of discovering a new shipwreck somehow had become a reality, and it was every bit as good as could be imagined. While reveling in the experience, I wondered if I would have enough skill and luck to ever make it happen again. Several discoveries later, the challenge is still irresistible.


Artifacts recovered after long immersion in salt or freshwater require conservation treatment if they are to last. On exposure to high concentrations of oxygen in the air, iron artifacts will bloom into piles of rust. Wood will crack and split if dried out improperly. Organic materials will crumble to dust.

The manual below details conservation methods for many types of materials and artifacts.


DAN

You would have to be crazy to dive in the North Atlantic ( or anywhere ) and not protect yourself with inexpensive accident insurance coverage available from DAN - Diver's Alert Network. Check your existing health insurance policy, and you will most certainly find that accidents involving scuba diving are excluded ( skydiving too ).

DAN offers various packages, tailored to everyone from the most occasional Caribbean diver to the hard-core Andrea Doria techie. Coverage includes recompression chambers, transport, and other costs, both in and out of the country. The yearly fee for all this is not much more than the cost of a mask, or a single day's boat diving, and also includes membership in the organization and a subscription to their excellent safety-oriented magazine Alert Diver.
