Hammerhead 01

Although great hammerhead sharks (Sphyrna mokarran) appear powerful and robust, recent research has shown that they are in fact one of the most fragile shark species, being particularly vulnerable to the stress of capture. Even those that are released after being hooked have a nearly 50% chance of succumbing after their ordeal.1 To better protect these sharks, a greater understanding of their movements is needed. The results of a new study conducted by scientists at the Bimini Biological Field Station in Bimini, Bahamas have provided a major step forward by showing the migration patterns and regional connectivity of great hammerheads between the Bahamas and the United States.

COP12logo

On the 23rd of October, more than 1500 representatives to the UN Environment came together in Manila, Philippines to conduct the 12th Conference of the Parties. COP 12, the twelfth Conference of the Parties, is an UN-sponsored conference organized by the Convention of Migratory Species, or CMS, as it is known. This landmark event, which takes place every three years, was established to set regulations and policy to maintain species sustainability around the world. 

            In Plenary sessions, working groups, and side events, the case is presented for what is needed and what is being done to promote sustainability.  This first short film introduces some of the key players, the scene, and the message of this critical conference on the sustainability of all migratory species. Part trade show and part science conference, all for sustainability of the planet. In the future more shorts will be edited from extensive interviews and content provided by the parties.

World Oceans Day at United Nations

WOD 01

World Oceans Day 2017 (June 8th) got an early start in NYC. Many events were planned for the week including the inaugural World Ocean Festival and the first ever United Nations Ocean Conference. Starting with a kickoff party at the Central Park Zoo, I joined in on the youth action for our oceans. Meeting up with like-minded citizens between the ages of 10 and 26, we mingled, learned about each other's work and discussed the plans for the Youth Rally for the Ocean happening the following day. We even made creative signs for the marchThat evening, Dr. Wallace J Nichols, author of Blue Mind, gave a truly moving speech. He also gave us blue marbles from his Blue Marbles Project for sharing random acts of blue gratitude around the world. Dr. Nichols said "do not ever make a video, give a talk, or write a report and leave out the vast emotional benefits of a healthy ocean." The audience was taken by his speech and couldn't wait to talk to him more about his blue mind studies!

The remote Calypso Reefs are off the South Eastern tip of New Guinea in Milne Bay. Few divers witness Calypso’s magical mystery tour, but those lucky few who get to experience it treasure it as one of the best dive spots on our planet.

“Bubbles Away”- Oceanic Omega 3 Review

Thursday, 22 September 2016 02:37

By Brett Lobwein

 

The Oceanic Omega 3 side exhaust regulator is the perfect choice for underwater photographers, videographers or SCUBA divers who want to avoid any distraction from focusing on the ocean. Apart from the exhaust [flow] bubbles being directed away from my face, as a photographer I really like the Omega 3’s profile. Being a side exhaust means there is not a bulky regulator pushing up against the back of the camera housing as you look through the viewfinder.

The biggest ‘upgrade” of the Omega 3 over the very popular Omega 2 is that it no longer breathes wet. It comes packaged out of the box with a MaxFlex hose* and a ball swivel, making it very comfortable plus dramatically reducing the regulator pulling against your jaw. Tech divers will also love that this regulator is ambidextrous “no up or down”, making it an ideal choice for a side mount setup.

I have managed to test the Omega 3 to a depth of 52 metres (170 feet). The entire way from the surface to 52 metres the Omega 3 delivered the perfect amount of air without the need for any complicated adjustment knobs. A simple twist operated dive/pre-dive switch is very handy to stop any free flowing on the surface.

Oceanic has paired the Omega 3 with the lightweight and top-performing FDX-i first stage. For those who want to explore colder oceanic waters, the FDX-i is ready with an environmentally sealed diaphragm. As you would expect this first stage is also balanced, which ensures the regulator performs consistently at any depth. I have also been very impressed with the well thought out port layout and positioning. The FDX-i uses Oceanic’s Dry Valve Technology (DVT) preventing water or other foreign objects from entering the first stage, ideal if you forget to put the dust cap on.

Complimenting its modern design, the Omega 3 comes in three colour choices—black, white or clear. Personally I love the clear, as it allows you to see the beautifully engineered internal workings of the second stage. After owning the Omega 3 for over 12 months, I am still blown away by its performance.

*Check with your local dealer that this is standard in your location
