Deep sea octopus broods eggs longer than any known animal – 4 years

Deep sea octopus broods eggs longer than any known animal – 4 years

Researchers at the Monterey Bay Aquarium Research Institute have observed a deep-sea octopus brooding its eggs for four and a half years – longer than any other known animal. Throughout this time, the mother kept the eggs clean and guarded them from predators.

Octopuses typically have a single reproductive period and then they die. Once a clutch of fertilized eggs has been produced, the mother protects and tends them until they hatch. In most shallow-water species this brooding period lasts between one and three months. Very little is known though about the maternal behaviour of deep-living species. In the cold, dark waters of the deep ocean, metabolic processes are often slower than their counterparts at shallower depths.

Extinction Threatens Quarter of Sharks and Rays

Extinction Threatens Quarter of Sharks and Rays

A quarter of sharks, rays and chimaeras are threatened with extinction, according to a new study by the International Union for Conservation of Nature. Large, shallow-water species are at most risk.

The group found that only 23 percent of these fish is listed as “least concern” on the IUCN Red List of Threatened Species. Of the 1,041 known species, 25 are listed as critically endangered, 43 are endangered, and 113 are vulnerable to extinction. This is the worst reported status for any major vertebrate group except for amphibians.

5 Surface Signaling Devices That Could Save Your Life

Locating a diver on the surface can be surprisingly difficult. I know, because I have been at both the searching and searched-for ends of this scenario. Even with surface signaling devices, locating a tiny, floating head amidst uneven chop can be difficult; without them it may be impossible. In an ideal world, divers would never be separated from their boats or buddies, but the ocean can be unpredictable, and freak currents and mistakes occur. Hopefully you will never find yourself lost a sea, but it's still a good idea to carry surface signaling devices on every dive -- just in case. Here are five devices that can make finding a diver on the surface easier.

Rich cold-water coral reef in the Whittard Canyon area by the Isis ROV

The UK’s National Oceanography Centre has produced the first true three-dimensional picture of submarine canyon habitats, using a unique combination of marine robotics and ship-based measurements. The information captured in this new set of maps ranges in scale from the 200 km canyon down to the size of an individual cold-water coral polyp, and will be used to inform the management of the only English deep water marine conservation zone.

Divers kill crown-of-thorns starfish with vinegar

Crown of thorns starfish, COTSCrown of thorns starfish, COTS

Scientists in Australia have discovered that vinegar kills Crown-of-Thorns Starfish just as effectively as the current drug, which can be expensive and difficult to source.

Outbreaks of the venomous Crown-of-Thorns Starfish (Acanthaster planci) pose one of the most significant threats to the Great Barrier Reef.

How Noisy were Whales before Industrial Whaling?

Concern is growing that human-generated noise in the ocean disrupts marine animals that rely on sound for communication and navigation. In the modern ocean, the background noise can be ten times louder than it was just 50 years ago. But new modeling based on recently published data suggests that 200 years ago — prior to the industrial whaling era — the ocean was even louder than today due to the various sounds whales make.

The Hunley has finally comes out of her shell

For the first time in over a century, you can actually see the original surface of the world’s first successful combat submarine. Until recently, the Hunley was completely encased in concretion, an encrusted layer of sand, sediment and shells that built up slowly over time while she was lost at sea.

By MarEx 2015-09-04 18:43:58

After a two year investigation by the U.K. Maritime & Coastguard Agency (MCA), a commercial diver has been jailed for two years and ordered to pay £35,000 ($53,000) after recovering historic cannons off the U.K. coast. 

Vincent Woolsgrove of Ramsgate, Kent, pleaded guilty to fraud at Southampton Crown Court after he reported to the Receiver of Wreck that he had found and recovered five historic bronze cannons from two different shipwreck sites.

Department of the Navy Issues Final Rules on Recreational Diver Access to Sunken Military Vessels

The Department of the Navy (DoN) has issued its final rules on the disposition of sunken military craft including an updated procedure required for research and other activities on these sunken vessels.  Importantly, according to a letter DEMA has received from the DoN, “…activities such as fishing, snorkeling and diving which are not intended to disturb, remove or injure any portion of a sunken military craft are still allowed without the need for a permit.” The revised regulations permitting investigations of sunken military craft under the jurisdiction of the DoN were published in the Federal Register Monday, August 31, 2015. The new regulations won’t officially go into effect until March 1, 2016.

When the holes line up in the cheese

I have heard the analogy about holes in the cheese several times and it pretty much sums up the incident pit.

I’ve been diving rebreathers for quite a while now, teaching them for nearly a decade and I have always been interested in rebreather diver incidents. There are many internet forums with sections dedicated to incidents where the person survived and that person can give a full account of what happened and why. Then there are the other sections of the forums where you read about diver deaths and almost certainly never get any details and a lot is left to supposition.

The reluctance to give known facts on diver fatalities stems from the respect to the families and the diver. The families do not want to read about how their loved one died and also if the diver made mistakes, friends do not want them to appear incompetent. From what I have read, there is almost never a catastrophic incident that takes the diver, it is always a series of events.

Predator fish that walks and breathes is on the loose in Central Park

Even creepier than the catfish that hunts pigeons on land, is the toothy northern snakehead, a carnivorous fish that grows to at least three feet in length, can breathe air and can survive for up to four days out of water. It can survive for even longer periods in mud and moist environments. Oh, and it travels over land by wriggling its body along the ground.

SCUBA Divers cause coral disease and damage – it’s official

SCUBA diving and snorkelling are amongst the fastest growing tourism sectors. The increasing numbers mean many more people are aware of the beauty and importance of the marine environment, but also puts a great strain on the coral. Not only is it damaged by inexperienced divers kicking it and pollution from boats and hotels, research also shows that coral is much more likely to become diseased in highly dived areas.

The Beautiful but Deadly Lionfish is the Creature of the Month

Lionfish, genus Pterois, is very popular amongst those with aquariums, and this trade may have led to them being described as amongst some of the most aggressively invasive species on the planet. Lionfish are native to the Red Sea, Pacific Ocean, and Indian Ocean, most often found around corals, reefs and rocky surfaces down to about 50 m. They have quite a distinctive appearance with their red and white stripes, together with large spiky dorsal fin rays containing venom for defense against predators. They don’t appear to have many natural predators, but large Groupers and Moray eels have been observed feeding on them.

Get the Most from Your GoPro Underwater

from Undercurrent Magazine

The GoPro Hero range of action cameras is a marvelous addition to your dive gear bag. I first wrote about GoPro and its Hero3 model in the November 2013 issue of Undercurrent, but in its latest Hero 4 incarnation with its watertight housings, these little POV cameras have an application for almost any activity, especially risky activities that might destroy a more conventional camera. No wonder GoPros proved to be the most popular Christmas present of 2014.

Diving for scallops

Imagine it’s your job to dive for scallops deep in the cold, murky waters off the Maine coast. It’s a hard job and one that fewer fisherman are doing.

Now imagine you have use of just one arm. That’s the case for James Sewell, who lost his right arm in a 2009 snowmobiling accident and resumed diving less than a year later, according to this New York Times video by Maine filmmakers Christoph Gelfand and Caroline Losneck.

“I’ve never been a person that likes for people to do stuff for me,” said Sewell, who also dives for urchins and fishes for bluefin tuna. “I like to do for myself.”

According to the Times, Sewell, 43, is one of only about 30 active scallop divers working on the Maine coast.

The video shows what that job is like for Sewell, who dives off his boat, the Sophie Elizabeth, out of Cushing.

“It’s just not a 9 to 5 job. Deep diving puts a lot of nitrogen into your blood. It’s hard on your joints. It’s hard on you,” Sewell says in the video. “Once you get to a certain age you’re not going to be able to keep doing it. I think about my family and the risks you take. Every day that you go down on bottom you have that chance of something fails or something happens — that might be the last time that you see them.”
