60-Foot Rogue Wave Captured in Pacific Ocean (Video)

60-Foot Rogue Wave Captured in Pacific Ocean (Video)

Yahoo7 hours ago

When thinking of rogue waves breaking out in the middle of the ocean, for surfers at least, one liquid monstrosity comes to mind – Cortes Bank, the mythical big wave gauntlet breaking some 100 miles off the California coast. As it turns out, however, these abnormally gigantic waves are breaking elsewhere in the world's oceans, too; and a team of scientists set out to explore them.
Specifically, the scientists looked at rogue waves being documented in the Pacific Ocean off Canada. They described: 'Once dismissed as a maritime myth, rogue waves are now increasingly being recorded in Canadian waters. A network of AI-powered buoys off the coast of B.C. is capturing these giants in real time. Johanna Wagstaffe meets the engineer developing new tools to understand — and maybe one day forecast — their chaotic nature.'
One in particular, which they detected back in 2020, was taller than a six-story building.
'So, this rogue wave was measured off near Tofino [Vancouver Island, Canada],' said Scott Beatty, CEO of MarineLabs Data Systems. 'There was a 17.5 meter [57 .4 feet] wave that came by. For context, that's about six stories. But the unusual thing about it, was that in the background the waves were six meters. It was the highest ever recorded. So, we had to go back and double, and triple check that.'
Unlike Cortes Bank, these waves are random. They happen sporadically, in the middle of the ocean, and are difficult to detect. When there's the right swell – and there's a crew willing to risk it all to motor out to Cortes, and attempt to surf it – things can be somewhat predictable. And they know where to find it. But these, open-ocean rogue waves are way more unpredictable.Here's how the scientists describe them:
'These waves are at least twice as tall as the surrounding waves. They're unpredictable. They can come from unexpected directions, often against prevailing winds and swells. You need a whole cocktail of factors to come together – wind, swell, current. It's a chaotic, nonlinear wave interaction, where one wave will suddenly gather energy from others and explode in size.'
Rare and terrifying, yet fascinating. Makes one wonder about all the untapped big wave surf spot potential just hiding out in the vast, open oceans.60-Foot Rogue Wave Captured in Pacific Ocean (Video) first appeared on Surfer on Jun 27, 2025

Rocks in Canada's Quebec province found to be the oldest on Earth

By Will Dunham (Reuters) -Along the eastern shore of Hudson Bay in Canada's northeastern province of Quebec, near the Inuit municipality of Inukjuak, resides a belt of volcanic rock that displays a blend of dark and light green colors, with flecks of pink and black. New testing shows that these are Earth's oldest-known rocks. Two different testing methods found that rocks from an area called the Nuvvuagittuq Greenstone Belt in northern Quebec date to 4.16 billion years ago, a time known as the Hadean eon. The eon is named after the ancient Greek god of the underworld, Hades, owing to the hellish landscape thought to have existed then on Earth. The research indicates that the Nuvvuagittuq Greenstone Belt harbors surviving fragments of Earth's oldest crust, the planet's outermost solid shell. The Nuvvuagittuq rocks are mainly metamorphosed volcanic rocks of basaltic composition. Metamorphosed rock is a kind that has been changed by heat and pressure over time. Basalt is a common type of volcanic rock. The rocks tested in the new study were called intrusions. That means they formed when magma - molten rock - penetrated existing rock layers and then cooled and solidified underground. The researchers applied two dating methods based on an analysis of the radioactive decay of the elements samarium and neodymium contained in them. Both produced the same conclusion - that the rocks were 4.16 billion years old. Future chemical analyses of these rocks could provide insight into Earth's conditions during the Hadean, a time shrouded in mystery because of the paucity of physical remains. "These rocks and the Nuvvuagittuq belt being the only rock record from the Hadean, they offer a unique window into our planet's earliest time to better understand how the first crust formed on Earth and what were the geodynamic processes involved," said University of Ottawa geology professor Jonathan O'Neil, who led the study published on Thursday in the journal Science. The rocks may have formed when rain fell on molten rock, cooling and solidifying it. That rain would have been composed of water evaporated from Earth's primordial seas. "Since some of these rocks were also formed from precipitation from the ancient seawater, they can shed light on the first oceans' composition, temperatures and help establish the environment where life could have begun on Earth," O'Neil said. Until now, the oldest-known rocks were ones dating to about 4.03 billion years ago from Canada's Northwest Territories, O'Neil said. While the Nuvvuagittuq samples are now the oldest-known rocks, tiny crystals of the mineral zircon from western Australia have been dated to 4.4 billion years old. The Hadean ran from Earth's formation roughly 4.5 billion years ago until 4.03 billion years ago. Early during this eon, a huge collision occurred that is believed to have resulted in the formation of the moon. But by the time the Nuvvuagittuq rocks formed, Earth had begun to become a more recognizable place. "The Earth was certainly not a big ball of molten lava during the entire Hadean eon, as its name would suggest. By nearly 4.4 billion years ago, a rocky crust already existed on Earth, likely mostly basaltic and covered with shallow and warmer oceans. An atmosphere was present, but different than the present-day atmosphere," O'Neil said. There had been some controversy over the age of Nuvvuagittuq rocks. As reported in a study published in 2008, previous tests on samples from the volcanic rock layers that contained the intrusions yielded conflicting dates - one giving an age of 4.3 billion years and another giving a younger age of 3.3 to 3.8 billion years. O'Neil said the discrepancy may have been because the method that produced the conclusion of a younger age was sensitive to thermal events that have occurred since the rock formed, skewing the finding. The new study, with two testing methods producing harmonious conclusions on the age of the intrusion rocks, provides a minimum age for the volcanic rocks that contain these intrusions, O'Neil added. "The intrusion would be 4.16 billion years old, and because the volcanic rocks must be older, their best age would be 4.3 billion years old, as supported by the 2008 study," O'Neil said.

Toxic algae blooms are lasting longer in Lake Erie − why that's a worry for people and pets

Lake Erie algal blooms, August 2011, along the southeast Lake Erie shore of Pelee Island, Ontario, Canada, 5 miles north of the international line. | Michigan Sea Grant Gregory J. Dick, University of Michigan Federal scientists released their annual forecast for Lake Erie's harmful algal blooms on June 26, 2025, and they expect a mild to moderate season. However, anyone who comes in contact with the blooms can face health risks, and it's worth remembering that 2014, when toxins from algae blooms contaminated the water supply in Toledo, Ohio, was considered a moderate year, too. The Conversation asked Gregory J. Dick, who leads the Cooperative Institute for Great Lakes Research, a federally funded center at the University of Michigan that studies harmful algal blooms among other Great Lakes issues, why they're such a concern. bulletin_current 1. What causes harmful algal blooms? Harmful algal blooms are dense patches of excessive algae growth that can occur in any type of water body, including ponds, reservoirs, rivers, lakes and oceans. When you see them in freshwater, you're typically seeing cyanobacteria, also known as blue-green algae. These photosynthetic bacteria have inhabited our planet for billions of years. In fact, they were responsible for oxygenating Earth's atmosphere, which enabled plant and animal life as we know it. Algae are natural components of ecosystems, but they cause trouble when they proliferate to high densities, creating what we call blooms. Harmful algal blooms form scums at the water surface and produce toxins that can harm ecosystems, water quality and human health. They have been reported in all 50 U.S. states, all five Great Lakes and nearly every country around the world. Blue-green algae blooms are becoming more common in inland waters. The main sources of harmful algal blooms are excess nutrients in the water, typically phosphorus and nitrogen. Historically, these excess nutrients mainly came from sewage and phosphorus-based detergents used in laundry machines and dishwashers that ended up in waterways. U.S. environmental laws in the early 1970s addressed this by requiring sewage treatment and banning phosphorus detergents, with spectacular success. Today, agriculture is the main source of excess nutrients from chemical fertilizer or manure applied to farm fields to grow crops. Rainstorms wash these nutrients into streams and rivers that deliver them to lakes and coastal areas, where they fertilize algal blooms. In the U.S., most of these nutrients come from industrial-scale corn production, which is largely used as animal feed or to produce ethanol for gasoline. Climate change also exacerbates the problem in two ways. First, cyanobacteria grow faster at higher temperatures. Second, climate-driven increases in precipitation, especially large storms, cause more nutrient runoff that has led to record-setting blooms. 2. What does your team's DNA testing tell us about Lake Erie's harmful algal blooms? Harmful algal blooms contain a mixture of cyanobacterial species that can produce an array of different toxins, many of which are still being discovered. When my colleagues and I recently sequenced DNA from Lake Erie water, we found new types of microcystins, the notorious toxins that were responsible for contaminating Toledo's drinking water supply in 2014. These novel molecules cannot be detected with traditional methods and show some signs of causing toxicity, though further studies are needed to confirm their human health effects. We also found organisms responsible for producing saxitoxin, a potent neurotoxin that is well known for causing paralytic shellfish poisoning on the Pacific Coast of North America and elsewhere. Saxitoxins have been detected at low concentrations in the Great Lakes for some time, but the recent discovery of hot spots of genes that make the toxin makes them an emerging concern. Our research suggests warmer water temperatures could boost its production, which raises concerns that saxitoxin will become more prevalent with climate change. However, the controls on toxin production are complex, and more research is needed to test this hypothesis. Federal monitoring programs are essential for tracking and understanding emerging threats. 3. Should people worry about these blooms? Harmful algal blooms are unsightly and smelly, making them a concern for recreation, property values and businesses. They can disrupt food webs and harm aquatic life, though a recent study suggested that their effects on the Lake Erie food web so far are not substantial. But the biggest impact is from the toxins these algae produce that are harmful to humans and lethal to pets. The toxins can cause acute health problems such as gastrointestinal symptoms, headache, fever and skin irritation. Dogs can die from ingesting lake water with harmful algal blooms. Emerging science suggests that long-term exposure to harmful algal blooms, for example over months or years, can cause or exacerbate chronic respiratory, cardiovascular and gastrointestinal problems and may be linked to liver cancers, kidney disease and neurological issues. In addition to exposure through direct ingestion or skin contact, recent research also indicates that inhaling toxins that get into the air may harm health, raising concerns for coastal residents and boaters, but more research is needed to understand the risks. The Toledo drinking water crisis of 2014 illustrated the vast potential for algal blooms to cause harm in the Great Lakes. Toxins infiltrated the drinking water system and were detected in processed municipal water, resulting in a three-day 'do not drink' advisory. The episode affected residents, hospitals and businesses, and it ultimately cost the city an estimated US$65 million. 4. Blooms seem to be starting earlier in the year and lasting longer – why is that happening? Warmer waters are extending the duration of the blooms. In 2025, NOAA detected these toxins in Lake Erie on April 28, earlier than ever before. The 2022 bloom in Lake Erie persisted into November, which is rare if not unprecedented. Scientific studies of western Lake Erie show that the potential cyanobacterial growth rate has increased by up to 30% and the length of the bloom season has expanded by up to a month from 1995 to 2022, especially in warmer, shallow waters. These results are consistent with our understanding of cyanobacterial physiology: Blooms like it hot – cyanobacteria grow faster at higher temperatures. 5. What can be done to reduce the likelihood of algal blooms in the future? The best and perhaps only hope of reducing the size and occurrence of harmful algal blooms is to reduce the amount of nutrients reaching the Great Lakes. In Lake Erie, where nutrients come primarily from agriculture, that means improving agricultural practices and restoring wetlands to reduce the amount of nutrients flowing off of farm fields and into the lake. Early indications suggest that Ohio's H2Ohio program, which works with farmers to reduce runoff, is making some gains in this regard, but future funding for H2Ohio is uncertain. In places like Lake Superior, where harmful algal blooms appear to be driven by climate change, the solution likely requires halting and reversing the rapid human-driven increase in greenhouse gases in the atmosphere.

Earth's oldest rocks date back 4.16 billion years

While rocks are not exactly living things, they are not immune to Earth's fury. Ever-shifting tectonic plates constantly devour and pulverize them, or some rocks get turned into diamonds from the immense pressure underneath our feet. While life on Earth has almost been wiped out at least five times, some rocks pre-date life on Earth and have stood the ultimate test of time. Gray rocks uncovered in northern Nunavik, Quebec, Canada may be the ultimate primordial find. The stones date back 4.16 billion years to the Hadean era and are the oldest known rocks on the planet. They are described in a study published June 26 in the journal Science. Earth was a ball of molten lava when it first formed about 4.5 billion years ago. Scientists originally believed that Earth's first eon–the Hadean–ended when the first rocks formed. A golden spike–a geological marker indicates a boundary between time periods–that ended the Hadean eon is about 4.03 billion years old and located in Canada's Northwest Territories. The Nuvvuagittuq Greenstone Belt, located over 1,000 miles southeast of the Hadean's golden spike, has long been known for its ancient rocks. However, researchers have disagreed about the true age of these plains of gray stone that line the eastern shore of Hudson Bay in Quebec. In 2008, researchers proposed that these rocks dated back 4.3 billion years. Other scientists using a different dating method contested, saying that contaminants from ages ago were altering the rocks' age and they were only 3.8 billion years old. 'For over 15 years, the scientific community has debated the age of volcanic rocks from northern Quebec,' study co-author and University of Ottawa geologist Jonathan O'Neill said in a statement. 'Our previous research suggested that they could date back 4.3 billion years, but this wasn't the consensus.' [ Related: How old is Earth? It's a surprisingly tough question to answer. ] This new study used rock samples from a different part of the Nuvvuagittuq Greenstone Belt. The samples were collected in 2017 near the municipality of Inukjuak, Nunavik, by study co-author Christian Sole, while was completing his Master's degree. To determine the age of these rocks, the team combined geochemistry with petrology–a branch in geology that focuses on the composition, texture, and structure of rocks and the conditions under which they form. They also applied two radiometric dating methods to see how radioactive isotopes of the elements samarium and neodymium change over time. [ Related: Ancient rocks tie Roman Empire's collapse to a mini ice age. ] They found that both chronometers indicated that the rocks are 4.16 billion years old. Since the planet Earth formed roughly 4.5 billion years ago, this puts the rocks within a few hundred million years of our planet's earliest day–somewhat close in geological time. Typically, primordial rocks like these are melted and used over and over again by Earth's moving tectonic plates. While scientists uncovered some 4 billion-year-old rocks in Canada's Acasta Gneiss Complex, finding them at the surface is not common. According to the team, this discovery opens a unique window on the early Earth, potentially offering up clues to its existence. 'Understanding these rocks is going back to the very origins of our planet,' O'Neill said. 'This allows us to better understand how the first continents were formed and to reconstruct the environment from which life could have emerged.'
