Was the Joke On You?  April 20, 2019

Rolex Perpetual Cuckoo Sub-MarinerMost readers spotted the April Fool’s spoof I sent out on April 1, although a few complained that I didn’t include booking details for Precious Island. Another good dive-related spoof came from The Onion, with an article announcing the launch of a diver’s cuckoo clock designed to go to 10,000 feet deep. “When you buy a Rolex Perpetual Cuckoo Sub-Mariner, you know you’re getting the most durable, highest quality clock available.” Don’t try to buy the clock nor ask for booking details for Precious Island.



Is This Why Whales Beach Themselves?  April 20, 2019

Divers know that fast ascents can kill. Whales don’t. A study in the Proceedings of the Royal Society highlights a link between naval sonar and the massed strandings of whales. Researchers in Las Palmas, Spain believe the animals could be victims of decompression sickness caused by fear -- they found nitrogen bubbles in the veins of stranded dead cetaceans, and blood clots in several of their organs. When the whales swim fast to move away from sonar, their heart rate accelerates, causing DCS.

Cocos Island Liveaboard Discount  April 20, 2019

Undercurrent subscribers can take advantage of a special $1,000 discount on a 10-day liveaboard trip to Cocos Island June 8-18, organized by the nonprofit Turtle Island Restoration Network. In addition to viewing and photographing the incredible marine biodiversity of the Eastern Tropical Pacific, you’ll have a one-of-a-kind opportunity to help TIRN staffers with their ongoing sea turtle and shark conservation research. Interested? Go to https://seaturtles.org/our-work/our-programs/cocos-island/ and quote the code UNDERCURRENT. Much of your cost may be tax-deductible.

When a Manatee Hugs You  April 20, 2019

While visiting Crystal River to snorkel with its famed manatees in late March, Florida resident Mandy Egner was following the required guidelines, of keeping her hands up while finning, so she was pretty surprised when a large manatee approached, hugged her and then flipped her out of the water. “It was definitely an unforgettable experience,” Egner recalled. There are two sides to every story, but the manatee was not available for comment.

Ocean Reef’s Full-Face Mask Recall  April 20, 2019

Not to be confused with the Aria snorkeling mask by the same Italian manufacturer, the U.S. Consumer Product Safety Commission are recalling about 1,000 Ocean Reef Neptune Space integrated diving masks, made between March and November 2018. They represent a potential hazard due to a possible restricted air-flow. Check if your mask is affected by comparing its serial number with those listed at www.oceanreefgroup.com. If yours is included, return the mask to where you bought it for a free replacement or refund.

Remaining Air Time Equals Remaining Range  April 20, 2019

Remember when we used to watch the fuel gauge of our cars and wonder how far the last bit of fuel would get us? Unfortunately, low-on-air divers don’t have the option to walk with a can to the nearest gas station. Looking at an standard pressure gauge with its needle in the red section can be unsettling, to say the least. That’s why more divers are opting for gas integration, often using a hoseless transmitter fitted to the regulator’s first-stage. The “remaining air-time” display is similar to the range indicator in a modern car, and accounts for your breathing rate and depth.

Why the Skulls and Boobs?  April 20, 2019

Diver Stuart Vernon went on social media to pose this question: “Why do so many scuba T-shirt designs make it look like scuba is for ex-Navy SEALs, or some sort of badass, when most of us are nice people? When conservation is now in the public’s mind, do you think this gives the wrong impression? Would you really wear a T-shirt with women’s breasts on it, or something more fitting for one of the Hell’s Angels?” Tell us about the worst scuba T-shirt designs you’ve seen – send an email to BenDDavison@undercurent.org

Red Sea Brothers Are Open Once More  April 20, 2019

After they were closed to divers as a result of multiple shark attacks, the Brother Islands are open to divers again but subject to new government rules: No boat can moor overnight; the daily maximum number of boats is limited to 12 at Big Brother and six at Little Brothers, and official permission must be received beforehand. And now it is forbidden to dump any organic waste within five miles of the area -- crews must wait to flush the sewage tanks when the boats are underway.
