100th Anniversary of the Sinking of the cruiser USS San Diego : Findings of the Two-Year Interdisciplinary, Multi-Agency Inquiry
And now it can be told. An interdisciplinary team of ten US Federal agencies, the military, scientists and academicians collaborated on a two-year study of the wreck of USS San Diego on the occasion of the 100th anniversary of its sinking, to determine definitely what happened that day. The study was undertaken in memory of the six sailors killed in the sinking. New technologies were employed in the study, including finite-element engineering modeling of the flooding and sinking timeline based on loads aboard the ship and interior compartmentalization, high density/definition photogrammetry mapping and side scan sonar analysis of the wreck, and underwater unmanned probes (AUV’s and ROV’s – autonomous underwater vehicle and remote-operated vehicle) equipped with laser beams to measure the structure.

On the boat is Eric and Sherry Trapp, husband and wife duo and long time local recreational divers; Grant Herron and Elizabeth Seely, both young recreational divers; and their boat driver Ralph Penland, a retired fisherman. These are members from Outcast Dive Club, a local recreational...
As diving history progresses, legend begets fact. Some stories are too good to dissolve in the brine of the sea and continue to endure. This is one such tale. By Gene Peterson Initially the Great Isaac was constructed to tow fuel barges for the WWII allied efforts. The...
Now, as we stood on the hotel balcony at the Marco Vincent Dive Resort in Puerto Galera, Philippines looking out over the pool and watching the water sloshing back and forth, we understood what life is like here on this part of the Pacific “Ring of Fire”.
Nestled in southwestern California, and straddling the Pacific Ocean, the Channel Islands is one of the United States’ most beloved, beautiful diving destinations. From San Miguel to the northwest, to San Clemente in the southeast, the island chain is renowned for its stunning displays of underwater life, made possible through lush kelp beds and unique geological playgrounds; combine these features with a strong natural bottom, and the result is a resplendent submerged menagerie filled with stellar attractions that urge scuba divers to return again and again. On its own, the Channel Islands makes for a superb addition to any recreational diver’s logbook, though each island (including individual recesses and swimthroughs) has its own distinct flavor worthy of another page; and when you get spectacular spiny lobster hunting, the attraction is manifold.
Located on the Caribbean side of the Yucatán Península, Cancún rises as the most spectacular place to enjoy beautiful turquoise waters and white sandy beaches. Founded in 1970, Cancún began tourist projects in 1974, and since then it has grown to be a home away from home for many visitors from all over the world. Cancún and its surrounding areas are located on mangrove jungles: a strip of hotels between a beautiful lagoon and the Caribbean Sea.
Sometime not so long ago the ocean carried a fleet of ships built mostly of concrete. Wood was the preferred medium for ship building for centuries until the late 19th century when ship manufacturing converted to the use of sheet steel. While sheet steel was the go to material for many years it became scarce during the first World War. This is when ship builders turned to using steel reinforced concrete, which uses less refined and easier to obtain steel reinforcing bar.
Bordered between seven states, and straddling the lines between Midwest and southeast, Kentucky is a state known for many iconic features. Kentucky gave to the world the legendary boxing champion and activist Mohammed Ali; Colonel Harland Sanders and his closely guarded blend of 11 herbs and spices; Louisville Sluggers; Ale 8; legendary pioneer Daniel Boone. It’s a land formed and tempered by adventures of all sorts: connected by a trailblazing spirit, which still inhabits its sun-dappled foothills.
