Finding Lost Shipwrecks & Sunken Treasure

Shipwrecks
Harsh weather, rocks, and war have sent many ships to the bottom of the sea for thousands of years. Airplanes and submarines have also met this fate. Divers now go about finding these shipwrecks and the associated sunken treasure, sometimes with great success. Fish and other creatures often live in and around shipwrecks as well.
DIVING FOR TREASURE WITH METAL DETECTORS
Divers use metal detectors for finding sunken treasure and remnants of shipwrecks. Ocean water interferes with some types of metal detectors, because of its salt content. A pulse induction detector will work best at sea. An induction-balance detector can also find metal underwater, but it’s more reliable in salt-free bodies of water. Sunken treasure remains more likely to be found near shipwrecks.
Though one might expect the ocean environment to destroy sunken treasure, the opposite is frequently true. According to the Encarta Encyclopedia, silt (sediment) protects many long lost valuables from the elements. However, extra care must be taken to extract such items without damaging them.
HISTORY OF FINDING LOST SHIPWRECKS AND SUNKEN TREASURE
The instances of divers finding and recovering items from lost ships are too many to list, but here are a few…
Starting in 1959, divers found and began exploring the S.S. Pomona, a large commercial ship that sunk off California in 1908. An octopus is thought to live in the boiler. A sponge diver near Turkey found the wreckage of an ancient cargo ship in 1973; the vessel had been transporting a large quantity of glass when it sunk. The Spanish ship Santa Margarita was located in 1980, near Key West. More treasure was recovered from it as recently as 2007.
During 1983-1994, American and Turkish archaeologists removed tin and copper from a ship that sunk over three-thousand years ago. Almost an entire shipwreck was retrieved from the ocean in 1982, though it was sunken for more than 400 years. The Titanic’s wreckage was finally located in 1985. A French expedition recovered lost jewelry and kitchen items from it two years later.
DISCOVERING SHIPWRECKS AS SAFELY AS POSSIBLE
Lost shipwrecks can be dangerous places to explore, so it’s important for divers to understand the proper safety precautions. Diving itself presents various dangers, thus the involvement of a shipwreck poses additional concerns. Training classes on shipwreck exploration and diving safety are available; they provide a good way of learning about this activity and finding professional answers to relevant questions. Some diving supply stores offer such classes.
Though there are many divers, the oceans are vast and shipwrecks plentiful, so finding sunken treasure and lost shipwrecks is still quite possible. Some of the locations prone to shipwrecks include Cape Horn (southern Chile), Diamond Shoals (Cape Hatteras), the Florida Keys, and Sable Island (Nova Scotia).
