A term that has crept into discussions of scuba diving safety comparatively recently is “situational awareness,” a concept that originally arose in the field of aviation but has now been extended to a wide range of human activities, from medicine and motoring to personal security and law enforcement. Simon Pridmore offers insights and advice on safe diving with a scuba sixth sense.

To help promote dive tourism in the Baltic Sea, the European Union’s Project Baltacar, a collaboration between Sweden, Finland and Estonia, has developed underwater heritage trails for visiting a selection of unique wreck sites in the three countries. In Finland, the project has established buoys and created dive site maps for a group of five wrecks from the 17th to the 19th centuries, located just outside Hanko. Susanne Lundvall reports.

It is estimated that hundreds of thousands of tons of ghost nets lie at the bottom of the Baltic Sea, often caught on shipwrecks, many of which are historical in significance. The Baltic Sea Heritage Rescue Project brings together volunteers from all over the world with the drive to locate, document and remove such ghost nets from wrecks in the Baltic Sea, thus saving marine life, protecting the wrecks and keeping their stories alive. Sabine Kerkau, one of the co-founders of the project, reports.

Looking at his body of work, Lorenzo Moscia appears to be a “triple-threat”—he is a photographer / videographer, composer and video editor. He is also a photojournalist and investigative reporter with a law degree, and a technical diver. X-Ray Mag interviewed him to learn more about his recent video, Underwater World, his creative process and his perspectives.

Sighting a sea turtle on a dive is always a pleasure. However, few know much about what they are like as animals. Being reptiles, it is assumed that they are essentially on automatic—emotionless and thoughtless. But we changed our minds about that when Merlin came. Ila France Porcher relays the tale of rehabilitating a sick sea turtle in Tahiti, at a time when turtles were often hunted for food.

Scapa Flow, located in the Orkney Islands of Scotland, is the site of the scuttling of the High Seas Fleet of the Imperial German Navy in June 1919 at the end of World War I. While many of the wrecks were salvaged following the war, the remaining wrecks have become popular dive sites. In recent times, efforts to learn more about these wrecks through multibeam sonar surveys and 3D photogrammetry have taken place. Rosemary E. Lunn interviewed key figures involved in these developments to gain further insight.

The waters running north to south from the Long Island coast to northern New Jersey are nicknamed “Wreck Valley” by local divers. Larry Cohen and Olga Torrey share the stories of some of the war shipwrecks found in these waters, located off the US northeastern coast.

Technical diving instructor and inventor Gregory Borodiansky is qualified to dive 20 different rebreathers. He is also a rebreather instructor on many units and a rebreather instructor trainer. Since Borodiansky has a background in electronic engineering and computer science, he took the features he liked on each unit and designed a front-mounted rebreather. Larry Cohen reports.
