Plastic Filled Turtles February 15, 2019
A new study by the University of Exeter and Plymouth Marine Laboratory in the U.K. showed that 102 sea turtles examined from three different oceans had each ingested between 150 and 500 pieces of plastics, micro-plastics and other synthetics. They’re dead of course.
Closed to Divers February 15, 2019
If you booked a Red Sea liveaboard this month you won’t be going to the Brother Islands, one of the best dive sites. Egypt’s Chamber of Diving and Water Sports, the governing body for scuba diving, announced the islands will stay closed to divers at least until mid-March. That action was first taken last year in response to some divers getting bitten by sharks. (See our article “Why are Red Sea Sharks Biting More Often?” in the January issue of Undercurrent).
Are Fish as Vain as We Are? February 15, 2019
It may have been proved that fish are sentient but the brainpower of marine animals ahs been considerably underestimated. Alex Jordan, an evolutionary biologist at the Max Planck Institute of Ornithology in Germany, is calling for an overhaul of the traditional hierarchy of animal intelligence, saying that despite their reputation for being “basically vacant”, fish perform exceptionally well on certain tasks. His experiment with cleaner wrasse proved that when confronted with a mirror, after some time they became enamoured of their own image, showing they might have a degree of self-awareness. https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3000021
A Hint of Good News on Coral Bleaching February 15, 2019
As the populations of corals across the world decrease thanks to climate change, there’s some good news coming from Israel. A recent study published by the Journal of Experimental Biology reveals that the spawns of the fully formed corals in the Gulf of Eilat in the northern Red Sea, inherited the same genetic imprint responsible for hot weather adaptation, making the gulf one of the few places on earth where the this underwater ecosystem will continue for years to come in the face of the deteriorating climate change.
Which Are Your Favorite Fins? February 15, 2019
Split blades, technopolymer paddle fins or traditional hard rubber fins like those of days of yore? We’re working on a story and would like your opinion as well as any problems you may have had. And what about the straps? Spring straps, bungee straps or traditional rubber-style straps? Write and tell us, not forgetting to say your town and state. BenDDavison@undercurrent.org

That Exploding Diving Computer Battery February 15, 2019
You may have heard about a dive computer battery exploding at the Düsseldorf Boat Show in Germany in late January. A non-rechargeable battery in A Heinrichs-Weikamp OSTC Plus computer can accept either a 3.6v rechargeable lithium-ion battery or a 3.6v non-rechargeable one. Someone got confused as to which was which and a computer exploded after it was erroneously put on a charging pad with a disposable battery installed. No serious injuries occurred, but 12 people were taken to the hospital as a precaution. Which is why you do not try to recharge non-rechargeable batteries. The company now no longer recommends the use of a non-rechargeable lithium-ion battery in this product.
What’s at the Bottom of Belize’s Blue Hole? February 15, 2019
British billionaire Richard Branson led a submarine expedition down there in December, and what did he and his crew discover at 400 feet deep? Plastic. Yes, besides the corpses of crabs, conches and other sea creatures that had fallen down there and died, they saw plastic bottles. In his blog on Virgin.com. Branson wrote it was “the starkest reminder of the danger of climate change I’ve ever seen ... we’ve all got to get rid of single-use plastic.”
Palau’s Jellyfish Lake Reopens February 15, 2019
After being closed to snorkelers for two years to allow its diminishing population to recover, this popular spot for divers and snorkeler has seen thousands of new golden jellyfish appear. Jellyfish Lake’s population was around 30 million in 2005, but a disastrous drought reduced that number to a few thousand in 2016. The Coral Reef Research Foundation determined in December that the number is now up to 630,000. Jellyfish Lake, 1,200 feet long and 100 feet deep, is a UNESCO World Heritage Site.

But Will Komodo Park Be Shut Down? February 15, 2019
Indonesia’s travel industry is up in arms against a suggestion by government officials in the East Nusa Tenggara province to close Komodo National Park for a year. The thought is, a ban on humans will boost the population of Komodo dragons, who’ve gotten lazier in hunting because they’re used to scavenging food from tourists, as well as the deer that are their main food supply but are being hunted illegally. Puzzled scientists say Komodo’s dragons are doing fine, but officials should do more to save those living outside park boundaries. A closure is still up in the air; however, there has been no mention of plans to stop any diving.

Why do divers die?
Last month, Undercurrent dug into annual reports from Divers Alert Network (DAN) and the British Sub-Aqua Club. They collate dive accidents and fatalities. The basic factors for many of those: being lazy, becoming obese and succumbing to panic. In this article, we'll look at other reasons why divers die, including heading into running boat propellers, being unfamiliar with the dive gear, and a not-that-well-known health hazard that leads to a quick death by drowning. You can read it for free here.
Traditional Fins are making a comeback.
Back in the day, all diving fins were made of hard rubber. There was no choice - thermoplastic technology was in its infancy. The big advantage was that, apart from the fin straps, they seemed to last forever. Then came lightweight technopolymer fins. You can read it for free here.
