A deep-sea octopus (Graneledone boreopacifica) is shown on a ledge near the bottom of Monterey Canyon, California, about 1,400 meters (4,600 feet) below the ocean surface.

 

WASHINGTON (Reuters) - If someone were to create an award for "mother of the year" in the animal kingdom, a remarkably dedicated eight-limbed mom from the dark and frigid depths of the Pacific Ocean might be a strong contender.

Scientists on Wednesday described how the female of an octopus species that dwells almost a mile below the sea surface spends about 4-1/2 years brooding her eggs, protecting them vigilantly until they hatch while forgoing any food for herself.

It is the longest known egg-brooding period for any animal, they wrote in the scientific journal PLOS ONE.

The scientists used a remote-controlled submarine to monitor the deep-sea species, called Graneledone boreopacifica, off the coast of central California.

They tracked one female, recognizable by its distinctive scars, that clung to a vertical rock face near the floor of a canyon about 4,600 feet (1,400 meters) under the surface, keeping the roughly 160 translucent eggs free of debris and silt and chasing off predators.

This mother octopus never left the oblong-shaped eggs - which during the brooding period grew from about the size of a blueberry to the size of a grape - and was never seen eating anything. The octopus progressively lost weight and its skin became pale and loose. The researchers monitored the octopus during 18 dives over 53 months from May 2007 to September 2011.

Bruce Robison, a deep sea ecologist at the Monterey Bay Aquarium Research Institute in Moss Landing, California, said this species exhibits an extremely powerful maternal instinct.

"It's extraordinary. It's amazing. We're still astonished ourselves by what we saw," Robison said.

Most octopus females lay a single set of eggs in a lifetime and die shortly after their offspring hatch. The newborn of this species are no helpless babies. The long brooding period enables the hatchlings to come out of their eggs uniquely capable of survival, emerging as fully developed miniature adults able to capture small prey.

At this tremendous depth, there is no sunlight - the only light comes from bioluminescent sea creatures - and it is very cold - 37 degrees Fahrenheit (3 degrees Celsius). "It may seem nasty to us, but it's home to them," Robison said.

During the brooding period, the mother octopus seemed to focus exclusively on the welfare of the eggs.

"She was protecting her eggs from predators, and they are abundant. There are fish and crabs and all sorts of critters that would love to get in there and eat those eggs. So she was pushing them away when they approached her," Robison said.

"She was also keeping the eggs free from sediment and was ventilating them by pushing water across them for oxygen exchange. She was taking care of them," Robison added.

This species measures about 16 inches (40 cm) long and is a pale purple color with a mottled skin texture. It eats crabs, shrimp, snails - "pretty near anything they can catch," Robison said.

Four years ago this month, archaeologists monitoring the excavation of the former World Trade Center site uncovered a ghostly surprise: the bones of an ancient sailing ship. Tree-ring scientists at Columbia University’s Lamont-Doherty Earth Observatory were among those asked to analyze its remains for clues about its age and origins. In a study now out in the journal Tree Ring Research, the scientists say that an old growth forest in the Philadelphia area supplied the white oak used in the ship’s frame, and that the trees were probably cut in 1773 or so — a few years before the bloody war that established America’s independence from Britain.

The entire ship was scanned before its removal to create a precise record of where each of its pieces were originally found. (Corinthian Data Capture LLC)

 

Key to the analysis was wood sampled from Philadelphia’s Independence Hall two decades earlier by Lamont tree-ring scientist Ed Cook. It turns out that growth rings still visible in the building’s timbers matched those from the World Trade Center ship, suggesting that the wood used in both structures came from the same region. As trees grow, they record the climate in which they lived, putting on tighter rings in dry years and wider rings in wet years. In the process, a record of the region’s climate is created, allowing scientists to see how Philadelphia’s climate differed hundreds of years ago from say, New York’s Hudson Valley. The climate fingerprint also serves as a kind of birth certificate, telling scientists where pieces of wood originated.

 

The ship itself has been tentatively identified as a Hudson River Sloop, designed by the Dutch to carry passengers and cargo over shallow, rocky water. It was likely built in Philadelphia, a center for ship-building in Colonial times. After 20 to 30 years of service, it is thought to have sailed to its final resting place in lower Manhattan, a block west of Greenwich Street. As trade in New York harbor and the young country flourished, Manhattan’s western shoreline inched westward until the ship was eventually buried by trash and other landfill. By 1818, the ship would have vanished from view completely until the terrorist attacks on Sept. 11, 2001 set in motion the events leading to the World Trade Center’s excavation and rebirth. 

Some of the trash found amid the ship’s remnants included this leather shoe identified by experts at Colonial Williamsburg as made sometime from 1790-1810.

But the quest to salvage the S.S. Central America — which went down in 1857 in a hurricane off South Carolina carrying 425 souls, as well as thousands of coins, bars and nuggets of California gold — has produced a quarter-century of broken dreams and legal nightmares.

The bones of the side-wheeler were discovered in 1988, nearly a mile and a half down. The finder hauled up glittering coins and boasted of treasure worth $1 billion.

But paralysis ensued as waves of insurers and angry investors filed rival claims. Recovery of the shipwreck languished as courtrooms echoed with charges of fraud. In 2012, the finder became a fugitive.

Now, with the legal obstacles cleared, a private company working with a court-appointed receiver has become the first to revisit the shipwreck in two decades. It is, the team was delighted to find, still heavy with treasure.

On April 15, the company, Odyssey Marine Exploration, lowered a robot into the depths of the Atlantic Ocean and hauled up five gold bars weighing 66 pounds — worth about $1.2 million as metal and more as artifacts. That step, the company says, opened a new chapter in the saga of the Central America that will include raising the rest of the gold and exploring the deteriorating shipwreck. “We want to show that it can be done right,” Gregory P. Stemm, Odyssey’s chief executive, said in an interview. “It’s a great opportunity.”

When it sank, the Central America was steaming toward New York with a cargo meant to strengthen the city’s banks. The 280-foot vessel was carrying so much gold — commercial and personal riches from the California fields estimated at three tons, as well as a rumored secret federal shipment of 15 tons — that its loss contributed to the Panic of 1857, considered the first global financial crisis.

From the start, the locus of the recovery drama has been Columbus, Ohio — a landlocked city not known for treasure hunters. It is, however, home to the Battelle Memorial Institute, a private contractor specializing in science and technology.

Thirty years ago, Thomas G. Thompson, a plucky Ohio native who was a young engineer at Battelle, began wooing investors with dreams of finding the Central America. Soon, the Columbus America Discovery Group was formed to finance the hunt, including a robot with lights, cameras, arms and claws.

The team hit pay dirt in September 1988: Piles of gold coins and ingots lay scattered across the ship’s rotting timbers, and overnight, the investors became millionaires — in theory, at least.

In all, the team lifted up about two tons of gold. If sold today as pure metal, it would fetch $76 million.

But as news of the sensational find went public, the group’s investors were not the only ones paying attention. Claims to the fortune came from an order of Catholic monks, a Texas oil millionaire, and Columbia University, where an oceanographer had provided Mr. Thompson with sonar imagery of what turned out to be the shipwreck. And scores of insurance companies insisted that the treasure was rightfully theirs because of claims paid more than a century earlier.

Thus began a legal battle that kept the gold locked away. The disputes crippled Mr. Thompson’s ability to raise new funds, and treasure. It was not until about 2000, when insurers were awarded $5 million in gold, that his hands were untied. He sold much of the remaining treasure that his team had recovered, making a reported $52 million.

But his 251 investors got nothing. In 2005, some of them sued. John G. McCoy, a Columbus mogul who had invested $219,000, told Forbes in 2006, “I think he was dishonest from the word go.” Mr. Thompson avoided courtrooms, always speaking through intermediaries.

One dispute centered on 500 coins that had seemingly vanished. In a 2012 filing, Mr. Thompson said they had gone into a trust in Belize, and in August of that year — when he failed to show up for a hearing — a federal judge ordered his arrest.

It turned out that Mr. Thompson and his assistant, Alison Antekeier, for years had lived in Vero Beach, Fla., in a mansion set on four acres. By the time federal marshals went there to arrest Mr. Thompson, they had fled.

The Columbus Dispatch, whose parent company had invested $1 million in the gold hunt, reported that the couple had left behind empty coin boxes, currency wrappers marked $10,000 (used to band $100 bills in stacks of 100), a bank statement listing a balance of more than $1 million, and a book on assuming a new identity.

Federal marshals had billboards put up in Ohio and Florida seeking information about Mr. Thompson and Ms. Antekeier.

Mr. Thompson’s last known lawyer, Shawn J. Organ, in Columbus, no longer represents the gold hunter. “He’s incommunicado,” said Liberty P. Casey, Mr. Organ’s office manager. “We haven’t seen him or been able to track him down.”

Last May, the marshals auctioned off Mr. Thompson’s 180-foot ship, the Arctic Discoverer. Its safe was empty.

An important part of the legal drama was resolved that month, when Judge Patrick E. Sheeran of the Court of Common Pleas in Franklin County, Ohio, named as receiver Ira O. Kane, a Columbus lawyer and businessman whose task was to recover as much gold as possible for the benefit of creditors and duped investors.

This March, Mr. Kane picked Odyssey — based in Tampa, Fla., and publicly traded — to resume the hunt.

The stakes? Mr. Thompson recovered 532 gold bars and some 7,500 gold coins whose total face value, in 1857 dollars, was $1,126,000. Experts hired by Mr. Kane estimated the likely face value of the remaining gold at $760,000, but put the range at $343,000 to $1,373,000. In other words, more than half the treasure could still be sitting at the bottom of the sea, at least in theory.

Mark D. Gordon, Odyssey’s president, told investors in March that the remaining treasure, thought to be mostly gold coins, would fetch at least $85 million if sold for its value to collectors. On eBay, $20 coins from the original haul sell for up to $26,500.

Not included in the receiver’s estimate was a cargo long rumored to be aboard the wreck: 15 tons of Army bullion. A best-selling book about the discovery, “Ship of Gold in the Deep Blue Sea” by Gary Kinder, published in 1998, called it a secret shipment meant to shore up the faltering Northern industrial economy, and said the Army had recently declassified its existence.

In an interview, Mr. Stemm of Odyssey said the reconnaissance dive and retrieval of the five gold bars on April 15, as well as two gold coins, was important for demonstrating that, contrary to rumors that the site had been looted, the deteriorating shipwreck was still tantalizingly rich with treasures.

“It’s clear they didn’t do a complete recovery,” Mr. Stemm said of the original team. He added that the dive “confirms that the site has remained untouched” since the last retrievals more than two decades ago.

Helping direct the April 15 operation was Bob Evans, the chief scientist and historian of the Recovery Limited Partnership, one of Mr. Thompson’s insolvent companies and the legal owner of the shipwreck. “I’m elated,” Mr. Evans said in an interview. “I’m fulfilling my dream.”

On April 23, the new recovery ship, Odyssey Explorer, sailed from Charleston to renew the hunt. As a prelude to recovering the remaining gold, Odyssey is surveying the wreckage and will perform an archaeological excavation of the remaining artifacts. The company also plans to collaborate with a scientist from the Woods Hole Oceanographic Institution to study deep-sea life colonizing the site, and to continue science experiments initiated by Mr. Thompson’s team.

Odyssey will absorb the expedition costs if little treasure is recovered. If the take is substantial, the company will get 80 percent until it recoups its costs. After that, Odyssey’s share will drop to 45 percent.

Judge Sheeran, like the surviving investors, is eager to see what develops.

The new plan, he wrote last year, bodes well for “the rebirth” of the enterprise and a renewed sense of awe as “more treasure, both historical and monetary, makes its way from the depths of the seas.”

As for Mr. Thompson, it seems likely that he, too — wherever he is — is giving serious attention to what emerges next from his ship of gold

plus fish bites swim fin off spearfisherman and devours a free meal

A spearfisherman diving three miles off Jupiter, Florida, was attempting to remove an amberjack from his spear when he noticed a goliath grouper approaching him with an eye toward a free meal.

The goliath grouper, a fish known to be inquisitive and fearless, also proved to be aggressive as Arif Sabir discovered while diving in a group that included his wife. Watch as Sabir gets attacked by the goliath grouper, which ended up getting exactly what it wanted:

Sabir, who owns a motorcycle salvage yard in Winter Park, Florida, usually dives off Port Canaveral but for an anniversary dive with his wife went farther south to a new area where he encountered the goliath grouper.

“I’m not used to diving around the big ones like that,” he told GrindTV Outdoor in a phone interview. “We don’t have anything like that up here in Port Canaveral.”

Goliath grouper can grow to 10 feet and weigh up to 800 pounds, though this one was in the 300- to 400-pound range.

Sabir described what happened: “I just shot a lesser amberjack and I was coming back into the group and trying to get him off my spear and into my stringer. Then I saw off in the distance that this big grouper had started eyeing me up and was coming over.

“I tried my best to get [the amberjack] off my spear, but the grouper was a lot faster than me and lined himself up, first disabled me, took my fin off, and grabbed my gun and the spear with the fish and went off and on his way.

“I‘ve honestly never seen anything like that before.”

Fortunately, the goliath grouper ate the amberjack and discarded the spear and gun in the sand a quarter mile away, where Sabir retrieved them.

“Which I’m kind of glad about because I didn’t want the grouper getting stuck with that,” Sabir said. “That would’ve been bad for him, an encumbrance.”

Sabir was also glad because he got his speargun and spear back. He said he was a bit miffed at seeing them float away with the big fish. Now he can laugh about it, as most others do upon hearing—and seeing—the funny fish tale.
