Meet ‘Eve’ the DNA-Collecting Robotic Fish

Posted on by August 28, 2024

A fascinating article by CNN about a robotic fish named “Eve” that swings its silicone tail side to side, as it glides fluidly through Lake Zurich’s chilly water, where it is being tested by SURF-eDNA. The student-led group has spent the past two years building a school of soft robotic fish – of which Eve is the latest.

“By making Eve look like a fish, we are able to be minimally invasive into the ecosystem that we’re surveying,” master’s student Dennis Baumann told CNN, adding that the biomimetic design should prevent other fish or sea life from being startled by her presence. “We can mix, we can mingle in the ecosystem,” he added.

Eve’s ability to camouflage itself as a fish isn’t its only utility. The autonomous underwater vehicle (AUV) is also equipped with a camera to film underwater, and sonar, which when paired with an algorithm, allows it to avoid obstacles.

Posted on by August 26, 2024

With preliminary races of the Louis Vuitton 37th America’s Cup now underway in Barcelona, Spain, the famous sailing competition is facing the storm of over-tourism protests that have swept across much of Europe, as well as, many tourist hotspots across the globe. 

The Guardian reports that according to its supporters, the America’s Cup will bring in €1bn to Barcelona, create 19,000 jobs and, by the time the last sail is furled on 20 October, have attracted an extra 2.5 million visitors to the city.

The ultimate sporting competition for the super-rich marks the latest attempt by the Spanish city to attract “quality rather than quantity” tourism.

Update : Bayesian Tragedy — Manslaughter Investigation, “Unsinkable,” & Many Question Unanswered

Posted on by August 24, 2024

Five days ago, the 56-meter-long sailing yacht Bayesian sank at anchor off Sicily in extreme weather. Fifteen people on board were rescued and seven died, including British tech tycoon Mike Lynch and his 18-year-old daughter, Hannah.

This morning Italian prosecutors said that they have opened an investigation into culpable shipwreck and manslaughter over the deaths in the yacht’s sinking. They stressed, however, that the investigation was in its initial stages and they were not currently looking at anyone specifically.

Contrary to initial reports that suggested the vessel may have sunk because of a waterspout, the authorities now say the most likely cause was a localized, powerful wind known as a downburst.

Workers ‘Treated Like Slaves’ on Scottish Trawlers

Posted on by August 21, 2024

A BBC investigation has revealed that dozens of workers from around the world may have been trafficked into the UK to work for a small family-owned Scottish fishing firm.

Thirty-five men from the Philippines, Ghana, India, and Sri Lanka were recognized as victims of modern slavery by the Home Office after being referred to it between 2012 and 2020.

The workers were employed by TN Trawlers and its sister companies, owned by the Nicholson family, based in the small town of Annan on the southern coast of Scotland.

Did S/Y Bayesian’s Design Contribute to its Catastrophic Sinking?

Posted on by August 20, 2024

The 56-meter-long sailing yacht Bayesian sank at anchor of Sicily in extreme weather early Monday morning, with the loss of one dead and six missing. Among the missing are British tech tycoon Mike Lynch and his 18-year-old daughter, Hannah.

Following the sinking, the most common question asked was “How could a well-found yacht of that size be knocked down and sink, even in the high winds and a reported waterspout that were present at the time of the tragedy?”

Was the yacht simply overwhelmed by the weather or was there some aspect of the design or operation of the yacht that made it vulnerable? The immediate answer is that it is just too soon to tell.

Apex Boats — the Unlikely and Dangerous Naval Drones of World War II’s Operation Dragoon

Posted on by August 18, 2024

Apex boat, Operation Dragoon

Based on the recent conflicts in the Black Sea and the Red Sea, it appears highly likely that the future of maritime warfare will be shaped by the use of naval drones. This made me wonder when the first naval drones were used in combat.

To the best of my knowledge, the first naval drones used in combat were the Apex boats used in Operation Dragoon, the Allied amphibious landing in the South of France during World War II, eighty years ago last week.

These drones were modified radio-controlled landing craft, loaded to capacity with high explosives, intended to be used to clear beach obstacles and mines. The Apex boats were moderately successful yet proved at times to be almost as dangerous to the Allied soldiers and sailors as they were to the Nazi defenders.

US Coast Guard Can’t Crew All Its Ships Due to Recruiting Shortage

Posted on by August 12, 2024

Last week, US Coast Guard Vice Commandant Adm. Kevin Lunday spoke at the Brookings Institution and addressed the service’s enlisted force’s ongoing 10 percent manning shortage.  Entering the fiscal year, the Coast Guard was about 3,000 members short of end strength numbers. “That’s the backbone of the Coast Guard,” Lunday said.

Due to the shortfall, the Coast Guard “can’t crew all our ships” and has had to “temporarily shutter some of our smaller stations,” the vice commandant said.

“We had to lay up three of our major cutters because we don’t have enough enlisted personnel to crew them.” Since the action, the service has shifted funds from other parts of the budget to bolster recruiting and retention.

Boaty McBoatface Returns From 55 Day Undersea Voyage

Posted on by August 11, 2024

Boaty McBoatface, referred to as the UK’s most famous robot, recently returned to Scotland after 55 days on a more-than-2,000km undersea scientific odyssey from Iceland, studying the pace of climate change. 

BBC reports that the autonomous underwater vehicle (AUV) was hunting for marine snow – “poo, basically” in the words of one researcher. This refers to tiny particles that sink to the ocean floor, storing huge amounts of carbon.

The deep ocean, referred to as the “twilight zone”, is enormously mysterious. Acting as the eyes and ears of the scientists, Boaty went there on the longest journey yet for its class of submarine.

Great Barrier Reef Threatened by Highest Ocean Heat in 400 Years

Posted on by August 8, 2024

In a new study, published in the journal Nature, scientists say that sea surface temperatures over the past decade in and around Australia’s Great Barrier Reef are the highest on record for 400 years. The study concludes that these increased temperatures, driven by climate change, now pose an “existential threat” to the vast coral reef.

Extreme heat has caused five mass coral bleaching events in the past nine years alone.

“The science tells us that the Great Barrier Reef is in danger – and we should be guided by the science,” Prof Helen McGregor, from the University of Wollongong, told BBC News.

Update: A23a, the Iceberg “That Refuses to Die,” Caught in Antarctic Vortex

Posted on by August 4, 2024

In January, we posted about an iceberg designated A23a, the world’s largest, which had begun to drift on the Antarctic Circumpolar Current into “iceberg alley.” As it drifted, it was being eroded by waves and melting in the relatively warmer waters of the Southern Ocean. The impact of the waves carved huge arches and caves in the 400-meter-high walls of the iceberg.

The expectations were that the berg would continue to melt as it drifted and would begin to break up, with luck, missing the British Overseas Territory of South Georgia.  

Instead, A23a went precisely nowhere, as reported by the BBC. It remains in place just north of South Orkney Islands, turning in an anti-clockwise direction by about 15 degrees a day. And as long as it does this, its decay and eventual demise will be delayed.

More Baltic Bubbly — 100 Sealed Bottles of Champagne Discovered in 19th Century Shipwreck

Posted on by August 1, 2024

A team of Polish divers discovered the wreck of a 19th-century vessel laden with about 100 sealed bottles of champagne.  The shipwreck is in the Baltic Sea in 60 meters of water about 20 nautical miles south of the Swedish island of Öland.

“I think we have a treasure,” Tomasz Stachura, leader of the Polish diving group Baltictech, posted to Facebook after the team’s July 11 discovery.

Stachura, who specializes in underwater photography, said the ship was in “very good condition” and “brimming with historical treasures, including crates of champagne, baskets of mineral water and porcelain,” according to the Washington Post.

Scientists Discover “Dark Oxygen” on the Deep Ocean Floor

Posted on by August 1, 2024

About half the oxygen we breathe comes from the ocean.  It was long presumed that this oceanic oxygen was produced by photosynthesis, the process by which green plants use sunlight to synthesize foods by absorbing carbon dioxide and water, emitting oxygen as a byproduct. For at least a decade, however, researchers have observed significant levels of oxygen in the dark, deep ocean, far too deep for sunlight to reach and therefore too deep for photosynthesis.

New research published in the journal Nature Geoscience reveals that nature has devised a way to produce oxygen without the involvement of plants. It’s “an amazing and unexpected finding,” Daniel Jones, a researcher at the National Oceanography Center in the United Kingdom who wasn’t involved in the study, tells CNN’s Katie Hunt.

Rather than relying on sunlight and plants, the new research concluded that “dark oxygen” is being produced in the deep ocean, apparently by electrolysis involving lumps of metal on the seafloor.

Yesterday, we posted about the sinking of the British sailing yacht Bonhomme William last week, following an attack by orcas in the Strait of Gibraltar. Fortunately, the crew were rescued without injury. 

Two days later, a sperm whale encountered a ship with a more tragic outcome. According to the BBC, the endangered sperm whale – nicknamed Julio by scientists – was killed in a collision with a vessel in the busy Strait of Gibraltar.

Researchers say this is the fifth sperm whale to die after being struck by a ship since they started monitoring the population in the area more than 10 years ago.

New Orca Attacks — Yachts Sunk Off Gibraltar & Damaged Off Coast of Brittany

Posted on by July 29, 2024

The mystifying attacks on sailboats by a pod of Iberian orcas continue.

The crew of the British yacht Bonhomme William had to be rescued after an orca sank their vessel in the Strait of Gibraltar, according to Spanish authorities. It is the latest in a long-running series of “interactions” between orcas and midsize sailing yachts off the coast of Spain.

Maritime Executive reports that the Maritime Rescue Coordination Centre at Tarifa received a distress call from the yacht Bonhomme William on Wednesday night. The crew reported that their vessel had been disabled by orcas, which had hit it several times, and was adrift about two miles off Punta Camarinal in the strait’s western entrance.
