"It's really one of the best wrecks on Long Island and I hope to keep diving it for a very long time," Rivera said.
Bricker, 58, of Bay Shore, said he began filming the wreckage "to try to get an idea of its structural collapse." He said the more than 100-year-old ship, which has been lying upside down in waters about 110 feet deep, was undergoing what he likened to a slow motion demolition of a building.
"Slowly but surely the ship is collapsing," he said. "Different areas are collapsing more than others. ... Some parts that were 20 feet above the sand, now they're 8 feet above the sand."
Bricker continued, "Imagine if you had a building several floors high. The floor above is collapsing down — what we would call pancaking down."

Although a mine had been suspected of bringing down the San Diego, it wasn't until 2018 that Navy researchers and oceanographers from the University of Delaware confirmed a naval mine from a German U-boat, U-156, which had lurked eight miles off the coast, had been the culprit, Newsday has reported.
According to an account on the Naval History and Heritage Command website, on July 19, 1918, the "San Diego was rocked by an explosion on the port side below the waterline, immediately causing the ship to list to port. [Capt. Harley H.] Christy, believing the explosion to be the result of a German mine or torpedo, ordered evasive maneuvers to avoid a second attack, but the engines had been rendered inoperable. The cruiser was rapidly taking on water and the captain ordered the crew to abandon ship. Of a crew of 1,183, six Sailors were lost in the sinking."
In the decades since, six recreational divers have died exploring the San Diego's wreckage, four of them between 1989 and 1990, according to Newsday archives.
The wreckage was such a popular dive site the U.S. Coast Guard established a 500-yard "exclusion zone" around the wreck for a time in 1992 because recreational divers had been removing government property from the site, such as ammunition, lanterns and personal effects, according to the Naval History and Heritage Command website. An agreement was reached between the U.S. Coast Guard and "local dive boat operators to cease further salvage of ordnance, and the wreck was reopened," the website said.
Bricker said he hoped the Navy wouldn't close off the San Diego to divers amid the vessel's deterioration.
"I'd hate to see that," he said.
In an email to Newsday, Kristina Higgins, a spokeswoman for the Naval History and Heritage Command, cited information from the Underwater Archeology team, stating, "The U.S. Navy views responsible members of the diving and snorkeling communities as stewards and effective ambassadors for the protection and preservation of sunken military craft. ... Responsible divers should recognize their limits and skill levels, and should approach sunken military craft with care and respect."
The statement added the Navy last inspected the wreckage in 2016 and 2017 as it prepared to commemorate the centennial anniversary of the San Diego's sinking in 2018.
Newsday reported on July 19, 2018, a naval officer, standing on a ship anchored off Fire Island, read the names of the six sailors who perished when the San Diego sank, calling the San Diego a "war grave that is as sacred as any of the graves at Arlington National Cemetery."
Higgins' emailed statement also said the Navy "does not anticipate restricting access to the overall site of USS San Diego, however, disturbance of the site ... continues to be prohibited."
There was a time when divers were removing ordnance and other items, "but the Navy shut that down right quick," Bricker said.
To Bricker, there's a world of knowledge to be gained from visiting the San Diego.
"People like the history of it. To explore it," he said, noting the wreckage has worldwide renown. "There is stuff to see."
