Search suspended for 12-year-old swept out to sea - San Francisco Chronicle


After searching into the early morning, then again after sunrise Tuesday, the U.S. Coast Guard called off its search Tuesday morning for a 12-year-old Fremont boy who was swept out to sea from a Half Moon Bay beach Monday.

The 12-year-old, his father and his 8-year-old brother were sitting on the sand at Cowell Ranch State Beach when a rogue wave hit them and dragged them into the ocean around 3:42 p.m. The strong surf and churning high waves roughed up the younger boy and the father and tossed them back on the shore while dragging the 12-year-old out to sea.

Friends and family members set up a Facebook page to help in the search for the boy, identifying him as Arunay Pruthi.

Arunay’s disappearance is the latest in a series of tragic “sneaker wave” incidents along the Bay Area coast. Since the start of the year, at least four people have been swept to sea from San Mateo County to Sonoma County. Several more have been rescued from the cold ocean waters and waves taller than 20 feet.

Dangerous surf conditions are common along the Bay Area coasts, particularly in San Mateo County. But the waves can be higher and the undertow stronger during the winter months when high surf warnings frequently occur. Rogue waves, unexpectedly large waves also known as sneaker waves, are always a threat.

“It’s almost become a cliché,” said Lt. Toni Pehrson, a Coast Guard spokeswoman. “But never turn your back on the waves. It is definitely a good idea to keep an eye on what’s happening and to pay attention to your kids.”

Search teams from the Coast Guard, the San Mateo County Sheriff’s Department, Cal Fire, California State Parks and the California Highway Patrol used boats, helicopters, drones and thermal imaging devices to search for Pruthi until about 1 a.m.

“They were out there well into the night,” said Rosemerry Blankswade, a spokeswoman for the sheriff’s department. “But they did not find him.”

Pehrson said the search was suspended around 10:30 a.m. and will be resumed if the agency receives any tips.

Arunay’s family is continuing to search, distributing posters with his image and contact information, and is asking for volunteers who will help comb the coastline on foot or using drones.

“We’re looking for volunteers, drone operators, anyone who can help locate him,” said his aunt, Seema Sangwan, who was at the beach when the incident happened. “We’re just hoping to recover him, whatever state he is in.”

Authorities said the group was sitting or standing on the beach when an unexpectedly large wave smacked into them and pulled them to sea. Other beachgoers immediately called 911; the father and younger boy were able to struggle back to shore. According to authorities, rescue crews briefly spotted the boy about 100 yards offshore before the waves dragged him under.

Sangwan said the family hopes the Coast Guard will resume the search.

Arunay’s disappearance was the second on the San Mateo County Coast in a little more than a week. On Jan. 10, a couple fishing were swept from their perch on rocks at Pescadero State Beach. The husband was able to make it back to shore, but the wife is still missing.

A 40-year-old man died earlier this month trying to save his two children who were caught in a sneaker wave in Sonoma County and are presumed dead. A San Jose man in his 30s was rock scrambling in the Marin Headlands on Sunday when he was pulled into the ocean by a sneaker wave and remains missing.

Dinosaur-era sea lizard had teeth like a shark - Science Daily


New study identifies a bizarre new species suggesting that giant marine lizards thrived before the asteroid wiped them out 66 million years ago.

A new species of mosasaur -- an ancient sea-going lizard from the age of dinosaurs -- has been found with shark-like teeth that gave it a deadly slicing bite.

Xenodens calminechari, from the Cretaceous of Morocco, had knifelike teeth that were packed edge to edge to make a serrated blade and resemble those of certain sharks. The cutting teeth let the small, agile mosasaur, about the size of a small porpoise, punch above its weight, cutting fish in half and taking large bites from bigger animals.

Dr Nick Longrich, Senior Lecturer at the Milner Centre for Evolution at the University of Bath and lead author on the paper, said: "66 million years ago, the coasts of Africa were the most dangerous seas in the world.

"Predator diversity there was unlike anything seen anywhere else on the planet. The new mosasaur adds to a rapidly growing list of marine reptiles known from the latest Cretaceous of Morocco, which at the time was submerged beneath a tropical sea.

"A huge diversity of mosasaurs lived here. Some were giant, deep-diving predators like modern sperm whales, others with huge teeth and growing up to ten meters long, were top predators like orcas, still others ate shellfish like modern sea otters -- and then there was the strange little Xenodens.

"They coexisted with long-necked plesiosaurs, giant sea turtles, and saber-toothed fish. The new mosasaur adds another dangerous predator to the mix."

The discovery also adds to the diversity of marine reptiles in the late Cretaceous. This suggests their diversity peaked just before an asteroid hit 66 million years ago, wiping out marine reptiles and the dinosaurs.

"We're still learning how diverse the mosasaurs were," said Longrich. "And whenever we think we have them figured out, another one turns up."

The fauna lived in the million years before an asteroid hit the earth at the end of the Cretaceous period, ending the reign of the dinosaurs and wiping out 90 per cent or more of all species on Earth. The high diversity found in the new study suggests that the ecosystem wasn't in decline before the asteroid hit; instead the ecosystem seems to suggest that marine reptiles were expanding in diversity before they abruptly went extinct.

The teeth seen in Xenodens are unlike those of any other reptile. But Dr Longrich, who worked on fishing boats growing up in Alaska, had seen something similar before.

He said: "It reminded me of the teeth in the jaws of the sleeper sharks we'd sometimes catch while fishing halibut on my brother's boat. I remember seeing what those sharks could do- they'd carve huge bolts of flesh out of the halibut, almost cutting them in half."

The authors suggest that, similar to sleeper sharks and related dogfish sharks, the unusual jaws allowed the animal to punch above its weight, cutting small fish in half, carving pieces out of larger prey, and perhaps even scavenging on the carcasses of large marine reptiles.

But rather than being an extreme specialist, the teeth probably let Xenodens eat a huge range of prey -- "They're like the knives sold on those old late night TV commercial- they'll slice through anything," said Longrich.

Anne Schulp, researcher at Naturalis Biodiversity Center in Leiden and Professor of Palaeontology at Utrecht University, and an author on the paper, said: "I'm blown away by the new discovery.

"I've been working on closely related mosasaurs for a decade or two now, and Xenodens shows this group managed to exploit yet another food source. They clearly were even more successful than we thought."

Dr Nathalie Bardet from the National Museum of Natural History in Paris said: "I have been working on mosasaurs for over 20 years and more specifically on those from the Maastrichtian Phosphates of Morocco which I am familiar with. I must admit that among the ten species that I know, this one has a so unusual and extraordinary dentition that at the beginning I thought it was a 'chimera' reconstructed with different fossils!"

Dr Nour-Eddine Jalil of the National Museum of Natural History in Paris and Universite Cadi Ayyad in Marrakech, said: "A mosasaur with shark teeth is a novel adaptation of mosasaurs so surprising that it looked like a fantastic creature out of an artist's imagination.

"Xenodens calminechari is further evidence of the extraordinary paleobiodiversity of the Phosphate Sea.

"It is as if nature is struggling to find all the combinations for an ever finer exploitation of food sources."

A sea of rubbish: ocean floor landfills - EurekAlert


The Messina Strait, a submarine bridge separating the island of Sicily from the Italian Peninsula, is the area with the largest marine litter density worldwide -more than a million objects per square kilometre in some parts-, as reported in a new review paper published in the journal Environmental Research Letters.

Also, over the next thirty years, the volume of rubbish in the sea could surpass three billion metric tons (Mt), as cited in the study, whose corresponding authors are the experts Miquel Canals, from the Faculty of Earth Sciences of the University of Barcelona, and Georg Hanke from the European Commission's Joint Research Centre (JRC), where scientists carry out research in order to provide independent scientific advice and support to EU policies.

Led by the University of Barcelona, this paper gathers the results of the scientific meeting on macrolitter that took place in May 2018, promoted by the European Commission's Joint Research Centre (JRC) and the German Alfred Wegener Institute (AWI). A team of twenty-five scientists from across the world treated issues such as data needs, methodologies, harmonisation and needs for further development.

The study provides a synthesis of current knowledge on human-sourced materials lying on the seafloor and goes through the methodologies to improve future studies, "highlighting the need to understand litter occurrence, distribution and quantities in order to provide insight for appropriate (policy) measures", notes Georg Hanke, who adds that "the paper also shows the need to employ new methodologies -i.e. imaging approaches- to cover areas that had not been considered previously, and provides tools to enable quantitative assessments such as those under the EU Marine Strategy Framework Directive (MSFD)".

Among other signatories of the article are experts from the University of Açores (Portugal), Alfred Wegener Institute (Germany), Utrecht University (Netherlands), the Norwegian Institute of Marine Research (Norway), the Secretariat of the Barcelona Convention on the protection of the Mediterranean Sea, Monterey Bay Aquarium Research Institute (MBARI, California, United States), the Institute for Global Change of the Japan Agency for Marine Earth Science and Technology Research (JAMSTEC, Japan), IFREMER (France) and Oxford University (United Kingdom), among other institutions.

When litter arrives before humans do

The ocean floor is increasingly accumulating marine litter. Whereas the largest seafloor litter hotspots -likely in the deep sea- are still to be found, plastics have already been found in the deepest point on Earth, the Mariana Trench -at a depth of 10,900 meters- in the Pacific Ocean. In some cases, litter concentrations reach densities comparable to large landfills, experts warn.

Despite the scientific community efforts, "the extent of marine litter on our seas and oceans is not yet fully known. The marine regions most affected by this problem are in landlocked and semi-enclosed seas, coastal bottoms, marine areas under the influence of large river mouths, and places with high fishing activity, even far from land", says Professor Miquel Canals, head of the Consolidated Research Group on Marine Geosciences at UB.

Canals highlights that "the level of waste treatment in coastal countries is decisive: the less treatment -or the more deficient-, the more waste reaching the ocean, and therefore, the ocean floor, which is a problem that affects specially third world countries".

The long journey of litter to seafloor

Plastics, fishing gears, metal, glass, ceramics, textiles and paper are the most abundant materials in seafloor litter hotspots. Geomorphological features, the submarine relief and the nature of the seafloor determine the distribution of litter items on the seabed. Ocean dynamics, --that is, processes such as dense water cascades, ocean currents and storms-- ease the transport and dispersal of litter across the ocean, from coasts to abyssal plains, thousands of meters deep. However, these factors do not occur in all ocean ecosystems and also vary over time and in intensity where they take place.

Due to a gravitational effect, light waste is usually transported along and into marine regions where dense currents flow --i.e. submarine canyons and other submarine valleys-- and where flow lines concentrate, such as nearby large submarine reliefs. Finally, materials transported by ocean dynamics accumulate in depressions and quiet marine areas.

The properties of materials dumped in the marine environment also affect their dispersion and accumulation on the ocean floor. It is estimated that 62% of the dirt accumulated on seabeds is made of plastics, "which is relatively light and easy to transport over long distances. On the other hand, heavy objects such as barrels, cables or nets are usually left at the point where they are initially fell or got entangled", says Canals.

Litter drowns marine life

Litter is a new threat to marine biodiversity. It is already known that nearly 700 marine species, 17% of which are on the IUCN red list, have been affected by this problem in several ways. Seabed entangled fishing gears can cause serious ecological impacts for decades because of ghost fishing. The slow decomposition of fishing nets -usually made of high-strength polymers- aggravates the detrimental effects of this type of waste on the marine ecosystem.

Other human activities -dredging, trawling, etc.- trigger secondary dispersal by remobilization and fragmentation of seafloor litter. In addition, seabed waste concentrations can easily trap other objects, thus generating larger and larger litter accumulations. It is paradoxical that waste may increase the heterogeneity of the substrate, which can benefit some organisms. Some xenobiotic compounds -pesticides, herbicides, pharmaceuticals, heavy metals, radioactive substances, etc.- associated to litter are highly resistant to degradation and endanger marine life. However, the extent of the effects of litter on the habitats of the vast expanses of the deep ocean still is a chapter to be written by the scientific community.

"In the Mediterranean Sea -says Miquel Canals- seafloor marine litter already is a serious ecological problem. In some places of the Catalan coast, there are large accumulations of waste. When there are strong storms, such as Gloria, in January 2020, waves throw this waste on the beach. Some beaches in the country were literally paved with rubbish, thus showing to which extent the coastal seabed is littered. There are also noticeable concentrations of waste in some submarine canyons outside Catalonia".

Robotic technology for large depths

Beach litter and floating garbage can be identified and monitored by simple, low-cost methods. In contrast, the study of seafloor litter is a technological challenge, the complexity of which increases with water depth and remoteness of the marine area to be investigated. The study reviews both methodologies allowing physical sampling of seafloor waste and in situ observations.

New technologies have enabled major advances in the study of the environmental status of the seabed worldwide. The use of unmanned remotely operated vehicles (ROVs) is critical for in situ observation, despite the limitations for physical sampling. Classic technologies such as bottom trawling also have limitations, as they do not allow determining the precise location of the bottom-sampled objects. "Future methodologies should aim at easing the comparison of scientific data from different places. It should also be easier for observation and sampling efforts to generate consistent data sets, something that we are still far from achieving", says Canals.

Avoiding excess waste generation to take care of the planet

Knowledge and data about seafloor litter are necessary for the implementation of the Marine Strategy Framework Directive (MSFD) and other international policy frameworks, including global agreements. The publication shows how research on seafloor macrolitter can inform these international protection and conservation frameworks to prioritize efforts and measures against marine litter and its deleterious impacts.

The authors warn about the need to promote specific policies to minimize such a serious environmental problem. The study also addresses the debate on the removal of litter from the seabed, a management option that should be safe and efficient. In relation to this, the Joint Research Centre (JRC) is co-chairing the MSFD Technical Group on Marine Litter, which provides an information exchange and discussion platform to provide agreed guidance for MSFD implementation.

"Marine litter has reached the most remote places in the ocean, even the least (or never) frequented by our species and not yet mapped by science," says Miquel Canals. "In order to correct something bad, we must attack its cause. And the cause of the accumulation of waste on the coasts, seas and oceans, and all over the planet, is the excess waste generation and spillage in the environment, and poor or insufficient management practices. As humans, we have little or no care at all to prevent litter from accumulating everywhere".

Coast Guard suspends search for Fremont boy swept out to sea at Cowell Ranch State Beach in San Mateo County - KGO-TV

HALF MOON BAY, Calif. (KGO) -- The U.S. Coast Guard has suspended the search for a 12-year-old boy who was swept out to sea Monday. They will begin searching again in the morning.

The boy was swept into the ocean at Cowell Ranch State Beach in Half Moon Bay. The boy's father and 8-year-old brother were also swept into the water but they were able to get out.

Rescue crews worked into the darkness and nighttime hours in search of Arunay Pruthi of Fremont.

His father provided us a picture in hopes that someone might have seen him.

Boats and helicopters were used to try and locate the boy.

"We're going to keep looking as long as we can," said supervising ranger Barbara Morris.

Initial responders could actually see the 12-year-old from a cliff seconds after they arrived.

"They saw a boy in the water about a hundred yards out and they lost sight of him, he unfortunately went under, and he has not been seen since," says Cecile Juliette of San Mateo County Fire.

Those officials say Arunay was sitting on the sand when a wave swept him, his father, and 8-year-old brother into the ocean. His father and brother were able to get out.

Witnesses say the waves were strong.

"The surf was really high it was actually kind of more like giant waves one after the other, like a washing machine as if you were in the water," said Lauren Roberge who described the chaotic seen for her location on the other side of the beach.

Monday night Arunay's heartbroken father could barely make out his words, telling us that he is hopeful the search continues until his son is found. Officials are attempting to do just that but, in the morning, when there is light.

"The biggest challenge at night is the lack of light. It's just really dark out there and you can't see really well," said Morris.
