The Dorsal Fin

Ocean Encounters has posted a video featuring divers Fred Buyle and William Winram freediving with great white sharks (Carcharodon carcharias) to their YouTube channel.

It’s not entirely clear from the video description where this was filmed other than somewhere in the Pacific Ocean. From the looks of it, there was also a healthy tuna population at the dive site.

CBS News has a feature on Anderson Cooper’s most recent “swimming with sharks” endeavor, which took place in the waters off of Cuba. Cooper enjoys the company of reef sharks throughout the video footage.

UPDATE: A reader has pointed out that the distance from the nearest point on Catalina Island to San Pedro’s Cabrillo Beach is approximately 18 miles, as the crow flies. Another reader has explained how the 30 mile distance was approximated in the comments.

30miledive.com is reporting that undersea explorer Scott Cassell completed his dive from Catalina island to San Pedro, California this past Saturday (September 17). Cassell was attempting to break a world record for a continuous dive, but equipment issues required Cassell to surface mid-way through the journey.

According to 30miledive.com, Cassell continued on with the dive after a brief surface interval on a support boat and completed the underwater trek in approximately 12 hours.

According to Cassell, his motivation for the dive was to “raise awareness about our shark populations.” He goes on to say that he remembers seeing many blue sharks (Prionace glauca) 20 years ago in the same waters he recently completed the distance dive. However, during his dive on Saturday, Cassell states that he did not see a single shark.

In what appears to be a promotional video of some kind for Omega watches, professional golfer Greg Norman (aka The Great White Shark) was filmed cage diving with white sharks (Carcharodon carcharias) off Australia’s Neptune islands. Norman is sponsored by the watch company as an “Omega Ambassador.”

From YouTube user davidwlitchfield comes a video featuring a white shark (Carcharodon carcharias) getting briefly stuck in the lower opening of a surface cage. After bumping into the boat, the shark quickly turns and gets his nose in between the bars of the cage. The diver in the cage is able to push the shark back using his camera allowing the shark to freely swim away.

The video description doesn’t indicate where this encounter took place, but given the time of year (assuming the video was shot recently) and the visibility, my guess would be South Australia.
