Caught on Video: False Killer Whale Leaps Over Snorkler

Watch the surprise in this video of a false killer whale visiting snorkelers in Tonga this year

Earlier this year, Scott Portelli, an Australia diver and trip leader, captured a very unexpected event when a false killer whale suddenly jumped over a guest. Or actually, behind a guest. The perspective looks otherwise though!

According to Portelli, "Today out on the water we had an unexpected encounter with a large pod of false killer whales." One of the false killer whales from the pod swam under the snorkler and suddenly leaped (what appears to be) right over him. This is a truly fun, and rare event, which Portelli has luckily caught on camera. 

"(You) never know what you are going to see in Tonga."

Caught on Video: A whale shark barrels down a spear diver, allowing a pursued tuna to swim off into the blue

Did a Whale Shark Save this Tuna?

Caught on Video: A whale shark barrels down a spear diver, allowing a pursued tuna to swim off into the blue

This video has gone viral and I wonder what really happened on this event.  A spearfisher got more that what he bargained for when a huge whale shark snuck up behind him and gave him a scare while preparing to shoot a tuna.

As we can see on the video, the spearfisher screamed when a massive whale shark swam towards him and even bumping him. It was definitely a big surprise!

So was the whale shark was saving the tuna? Was it simply feeding and not worried about hitting the diver? Regardless the reason, that tuna was very lucky to get away.  The spearfisher was also luck to get out of that situation unharmed.

False Killer Whales Hunting Caught on Camera
By Chino Mendoza

False Killer Whales Hunting

Chino Mendoza
False Killer Whales Hunting Caught on Camera

False killer whales (Pseudorca) are uncommon to find everywhere. Seth Conae, a luck videographer was able to capture this epic event of false killer whales hunting.  He described it as a "National Geographic Moment" taking place in front of him, 

He was diving of the waters of Kailua-Kona, about three miles of the coast when this happened.  “When that first false killer whale showed up, it was pretty amazing how close it got. It was surreal”. But the succeeding turn of events made it more amazing. A pod of 6 false killer whales came after the first one appeared, and seem to be hunting. “Seeing the mahi-mahi circle around the bag and watching the other ones come in like they were calling each other, and then them all working together to basically try to get their prey”. 

“I think it was already in protective mode or hiding mode and trying to stick around that bag because I think it knew the false killers were in the area,” according to Conae.

Then one of the false killer whales slapped the 50-pound mahi-mahi of the water with its fluke.  One at a time, the false killer whales attacked the mahi-mahi until one of the bigger ones made the final kill.      

On the video, you could hear Conae's excitement. “It’s hard to control yourself when you’re in the moment and you’re watching something that you can’t wrap your head around”.  This was truly an event to remember.     

 

Video was taken from Khon2

New Deepblu app upgrade lets you integrate video into your digital dive log with option to share on social platform
By UWPG Editors

Add Video to your Dive Log

New Deepblu app upgrade lets you integrate video into your digital dive log with option to share on social platform

Deepblu has just added two new features to their popular dive log and social platform app: dive log video and instant messaging.

The Deepblu video integration is simple. Shoot video during your dive and then upload it to the Deepblu iOS app, where it will appear at the proper chronological point in the dive. You can then opt to share the dive on Deepblu's social platform. Once shared, the second new feature - instant messaging - lets friends and other users comment on your video. 

In an age where most cameras use WiFi and NFC to connect to your mobile device, sharing of photos and videos on social media is easy. Logging your dive is just as easy with the COSMIQ dive computer, which syncs automatically with the Deepblu app. The next step is natural; upload the photos and videos to your dive log to share with friends.

 

 

PRESS RELEASE

 

Share Your Dive Story Like Never Before

 

Deepblu, the digital dive log app and social network for divers, announced the release of an iOS app upgrade which will allow users to upload videos to their digital dive logs. The introduction of video integration is a major step forward that sets Deepblu further apart from other dive log apps and will certainly make a splash among underwater videographers – of both the pro and amateur variety.

The Deepblu app is a mobile platform where you can create digital dive logs, connect with your dive buddies, and share your diving experiences with other Deepblu users. Deepblu’s digital dive logs reimagine paper logbooks to better reflect today’s technological world and our desire to share experiences on social media. Divers can integrate photos and videos with dive data, write a story about their dive, tag dive buddies in their logs, and have their instructors validate dive logs. 

Offering the enhanced connectivity of a modern social network, Deepblu provides scuba divers and freedivers with the opportunity to continue their diving adventure above the surface and relive the best moments of every dive.

Now, anyone with a waterproof video camera can instantly share their underwater experiences with a group of like-minded people. Users can upload videos that run up to three minutes long and combine videos with photos to make truly rich and detailed dive logs.

In addition to video uploading, the new upgrade will unveil an instant-messaging function – another first for a dive log app - so you can coordinate your next diving trip or connect with new divers on the platform. Any two users on the platform can send each other instant messages, as long as they are buddies first.

The introduction of these functions takes Deepblu a step closer to its ultimate goal: creating a full-blown social network for divers.

The Deepblu app is available for free download at the Apple App Store and the Google Play Store.

Scallop diver helps underwater photographer be reunited with camera

Underwater Photographer Reunited With Camera

Chino Mendoza
Scallop diver helps underwater photographer be reunited with camera

Last July, diver and underwater photographer Kevin Mcllwee lost is £8,000 camera when the securing clip came off and left his camera on the sea bed.  He was already about to give up hope in finding his camera again.

For five weeks, he thought all was gone but a scallop diver, Josh Dearing along with his father, Mike Dearing, saw the camera while gathering scallops on the rocky seabed of St. Brelade's bay, Jersey.  

Josh Dearing was very surprised and amazed to find the camera still working despite being submerged for a long time and covered with cuttlefish eggs.  The camera was undamaged during the whole duration that it was underwater.

According to Kevin Mcllwee, "the saving grace was that the camera was in a vacuum sealed box.  Once sea water penetrates into equipment it will deteriorate in seconds.  Everything is working as it was before"

In conclusion, it would be beneficial to have a vacuum system on your underwater housing for extra protection and for peace of mind that everything is sealed.

Nauticam is pleased to unveil NA-G7XMKII, the premier underwater housing available for Canon G7X Mark II.  G7X Mark II camera stands out from a crowded class of advanced compact cameras thanks to its overall image quality, snappy autofocus, excellent manual white balance, and useful built in macro mode.  This impressive feature set, paired with the most ergonomic, rugged, and easy to use underwater housing available forms a perfect underwater imaging combination.

 

The Canon G7X Mark II Camera

G7X Mark II is the latest large sensor "Powershot" compact camera using the popular 1" sensor size.  This 20 megapixel Back Side Illuminated (BSI) CMOS sensor is paired with a best in class, fast 24-100m zoom lens.  This lens is extremely fast for a compact camera, with a maximum aperture of f/1.8 at wide angle, and f/2.8 at telephoto.  A new processor offers performance improvements across the specification range, most notably in continuous RAW shooting speed (increased from 1 fps to 8!).  Numerous tweaks to the control layout, body form factor, and control interface have taken an already very good compact to the next level.

 

 

The Nauticam NA-G7XMKII Housing

NA-G7XMKII is the latest iteration in a lineup of advanced housings for very capable compact cameras supported by Nauticam.  Many features found on professional DSLR systems have been integrated into this system, and the result is an underwater housing that allows the user to harness the full potential of this advanced compact camera in water.   The basic functions and ergonomic enhancements that Nauticam users have grown to know and love are incorporated in NA-G7XMKII.  The housing is machined from a solid block of aluminum, then hard anodized to seal out corrosive salt water.  It is closed via a simple, yet secure locking rotary latch. The right side of the housing is sculpted to fit the palm of the user's hand, and Nauticam's two-stage shutter release lever provides clear differentiation between the half press and full press shutter release positions.  All functions are clearly labeled.

 

 

The Nauticam leak alarm and vacuum monitoring system is installed as standard equipment.  This system provides an audible and visual alert to any water entry in the housing, and when combined with an accessory M14 Vacuum Valve (#25624) the water tight integrity of the system can be tested before ever entering the water and monitored during every dive.

Expert product design, modern manufacturing techniques, top quality materials backed by a two year warranty, and a critical focus on the user experience combine to produce the premier system for Canon Powershot G7X Mark II.  The Nauticam NA-G7XMKII.

Key Features

Rotary Locking Latch & Drop in Camera Loading

Stainless Steel Handle Brackets & Shutter Release Extension

Stiffening handle brackets and an oversized "trigger" style shutter release lever are included with the housing as standard equipment.  Combined with a Nauticam Flexitray or Flexitray W (optional), these brackets eliminate any flex or wobble when using big strobes, and provide multiple attachment points for lanyards and other accessories.  The shutter release extension is ideal for use in cold water with thick gloves.

 

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is shipped with NA-G7XMKII as standard equipment.  Combined with an accessory vacuum valve (PN 25624), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing.  A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur.

Sansha Yongle Blue Hole in China has been determined to be the new deepest blue hole
By Chino Mendoza

New World's Deepest Blue Hole Discovered

Chino Mendoza
Sansha Yongle Blue Hole in China has been determined to be the new deepest blue hole

Sansha Yongle Blue Hole or "Dragon Hole" as local fishermen refer to the underwater sink hole found in Parcel Island, South China Sea has now been concluded as the deepest blue hole in the world. It surpassed the current record holder, Deans Blue hole near the Bahamas by more than 300 feet.

After almost of a year of exploration, Chinese researchers determined that this is the deapest blue hole, reaching the depths of 987 feet below the surface and its opening measures 426 feet.  The team used an underwater robot during the exportation and discovered more than 20 species of fishes and marine life. One of their discovery about the blue hole was after 330 feet, the water is oxygen free and likely unable to support any marine life.

 

 

Last July 24, 2016, Sansha City offically named the blue hole as "Sansha Yongle Blue Hole" and has already drafted their plans of having this unique formation to be protected.

 

 

Blue holes got their name from their dark blue coloring which contrasts the surrounding water.  It can also be described as a underwater caves with beautiful formation and is similar to sink holes. Other known blue holes are Great Blue Hole in Belize and Dean’s Blue Hole located near Long Island in the Bahamas. Dean's Blue Hole was the previous deepest blue hole in the world.

The new underwater microscope shows us coral behavior and other microscopic life outside the lab
By Chino Mendoza

Underwater Microscope Unlocks Secret of Coral Life

Chino Mendoza
The new underwater microscope shows us coral behavior and other microscopic life outside the lab

The new underwater microscope, Benthic Underwater Microscope (BUM), brings marine scientists a whole new perspective on understanding coral sea life.  BUM was developed by Andrew Mullen and his colleagues at Scripps Institution of Oceanography - University of California San Diego (UCSD).  It has accomplished what no microscope had done before... which was to record tiny underwater organisms in their natural habitat.

One of the team's studies focuses on corals. According to Mullen, "We have looked at coral polyp behavior during competition, coordinated behavior between polyps of the same colony, and the colonization of bleached corals by algae."

 

 

Off the cost of the Red sea, BUM captured two different coral species competing for space on the seafloor. It showed a chemical enzyme being secreted to destroy the other species. They also observed on another occasion that this behavior did not happen when the same specie was close to each other.  This shows that corals engage in aggressive behavior in order to survive but do not compete with their own species.

On one of their recent trips to Maui, Hawaii, researchers were documenting the ongoing battle of corals and algae.  They recorded that during high ocean temperatures, the algae that lives inside the polyps ejects itself, which would eventually lead to bleaching.  

 

 

BUM is comprised of an underwater computer that a diver would operate and a special microscopic imaging unit.  The unit includes a high-magnification soft lens that focuses similar to how human eye focuses.  For lighting, it uses a bright LED focus ring.  The current BUM housing is capable of reaching depths of 100ft (30m), but they usually operate around 30ft (9m) deep.

BUM is truely a great tool in discovering and learning about the microscopic aspects of our marine environment. Researchers are continuously studying other marine behavior which may help in preserving our precious ocean ecosystem.
