The Thorfinn Sinks :  July 10, 2007

Lance Higgs, who has been serving divers in the Truk Lagoon on his funky liveaboard, Thorfinn, for 26 years, ran the boat aground in Pohnpei on June 8. It’s unlikely to serve again as a dive boat. Higgs said the Thorfinn began taking on water and he had to put it on the reef to avoid sinking in the channel, but it contained gallons of oil. Amid the complex legal wrangling over salvage of the craft, oil leaks, moving it from the reef and preventing sinking, Thorfinn does not carry pollution or indemnity insurance. If oil spillage causes ecological damage to Pohnpei, the cost would be inestimable. Read the full story at .

FBI alert :  July 10, 2007

The FBI thinks scuba terrorists might be planning nefarious activity and has asked the dive industry to turn in any individuals who request “specialty training, including odd inquiries that are inconsistent with recreational diving.” These may include: requests to dive in murky water or sewer pipes; requests to learn advanced skills associated with combat swimming, including use of rebreathers and diver propulsion vehicles, deep diving and extra navigation training; requests for advanced diver training by applicants from countries where diving is not a common recreational activity; training sponsored by religious organizations, cults, associations, or charitable agencies not normally associated with diving; paying cash for diving instruction; and refusal or reluctance to provide personal information.” Time magazine reports that the FBI described the advisory as routine and said it was not prompted by any threat. On a related note, we’ll have an article about underwater weapons to combat scuba-diving terrorists in our August issue.

One for Michael Moore :  July 10, 2007

St. Mary's Medical Center in West Palm Beach, Florida discontinued emergency hyperbaric chamber services as of July 1, so anyone bent in nearby waters will have to be transported to Miami or Orlando. The chamber had fewer than 50 emergency patients a year, and many divers who got hyperbaric services were uninsured. The two physicians overseeing the hyperbaric services did not like being on call without being paid by the hospital.

Enlist in REEF’s Annual Fish Count :  July 10, 2007

The Reef Environmental Education Foundation is holding its Great Annual Fish Count in July, conducting fish ID courses around the country and recruiting divers to survey fish in coastal waters of the continental U.S., Hawaii and the Caribbean. Past fish count surveys led to the discovery of the Mardi Gras wrasse in the Gulf of Mexico and two goby species near Veracruz, Mexico. To participate, sign up for a free fish ID course or request survey report forms to take on your next dive, e-mail or visit .
