Doug and Charlotte Kennedy arrived early Thursday at the Mooretown Dock with their grandchildren to see Theodore TOO, a replica of the star of the children’s television show Theodore Tugboat.
“Our daughter was actually taking a yoga class last night in the park and saw it and sent us a picture,” Doug Kennedy said.
“We babysit our two grandchildren, so this was perfect,” he said after taking their photos next to the smiling tugboat.
Aug. 26 was the first day of a three-port visit to the Sarnia area arranged by Tourism Sarnia-Lambton, with the help of sponsors.
The working replica of the title character from the children’s show that appeared on CBC Television from 1993 to 2001 was built in 2000 in Nova Scotia and recently made Hamilton its new home port.
The public was invited to stop by Mooretown until 6 p.m. to take photos and see Theodore TOO from shore and then the tugboat was moving to Sarnia’s Centennial Park to appear Aug. 28 and 29 from 9 a.m. to 6 p.m.
After that Theodore TOO was scheduled to make its way to the Grand Bend Pier for Aug. 31 and Sept. 1 from 9 a.m. to 6 p.m. before making a return visit to the Mooretown Dock on Sept. 3 from 9 a.m. to 6 p.m.
The visits to the Sarnia area are sponsored by Carpenters Local 1256, as well as well as Point Edward’s accommodation tax on hotel rooms, and other local groups.
Jessica Hayward showed up early Thursday with her son, Hayward, 3, at the dock in Mooretown.
She said they haven’t watched the show but did spot the tugboat Wednesday afternoon on the St. Clair River when it passed Sombra, where they live.
“He was excited to see it come by and we thought we’d get a close-up look,” Hayward said. “He loves boats.”
Mark Perrin, executive director of Tourism Sarnia-Lambton, said they noticed in the spring Theodore TOO was moving to Hamilton and its new owners were planning to have the tugboat visit communities.
“I talked to my kids who were right away excited about it,” he said.
The tourism agency made a call to the new owners, who said the plan was to do a Great Lakes Tour in 2022, Perrin said.
“We said, ‘What about a pilot project and bring it to Sarnia-Lambton?’”
It was a chance to give families across Lambton County’s waterfront something to enjoy at the end of the summer while also attracting visitors to the area, he said.
“I think everybody just lights up when they see it,” Perrin said.
The tourism agency’s social media also lit up after the visit was announced, with more than 2,500 shares and 100,000 views in the first 24 hours, he said.
“It’s going to be an awesome week, Perrin said.
Caitlin Simpson, captain of Theodore TOO and its four-member crew, said the trip from Hamilton went well.
“I haven’t been through the Welland Canal in some time, so that was, I think, my favourite part until I got here, obviously” she said.
Simpson has 30 years of experience on the water, including time spent sailing tall ships.
“It’s real interesting contrast between the serious business of shipping and the whimsicalness of being a children’s entertainment icon,” she said.
Simpson said this was her first “gig” as captain visiting ports for a public event with Theodore TOO.
“I’m really excited to open up shop and be alongside with people for the day,” she said.
Simpson said Theodore TOO will be an advocate for the marine industry and encourage young people to consider it as a career.
“It’s an industry that is really going to be starving for new people in the next couple of years,” she said.
Theodore TOO’s owner, Blair McKeil, said in June the tugboat will also be part of a collaboration with the water education and conservation advocacy organization, Swim Drink Fish.
Ancient Jordanian town destroyed by a meteor blast may have inspired Biblical stories, scientists say – CBC.ca
A thriving town in the Jordan River valley was utterly annihilated by the explosion of a meteor 3,600 years ago, which produced a flash and shock wave that scorched and shattered buildings, animals and people.
That’s the scenario painted by a large collaboration of archaeologists, earth and space scientists who have been studying the remains of the Bronze Age town at a site called Tall el-Hammam in Jordan, not far from the Dead Sea.
Before its destruction, Tall el-Hammam was a bustling town of perhaps 8,000 people, with mud-brick buildings and a four-story palace. There is evidence that the site of the town had been occupied for several thousand years.
Archaeologists have been excavating the ruins of the town for more than 15 years, revealing a rich history during its long occupation that included ruins from fires, warfare and earthquakes.
Their findings were published this month in the journal Scientific Reports.
The ‘destruction layer’
But their excavations also revealed destruction that didn’t have any ordinary explanation: a one-and-a-half-metre-thick layer of debris the team dubbed the “destruction layer,” encompassing the whole settlement, and dated to 1650 BC. This layer showed signs of an incredibly violent event.
It included melted pottery and bricks, soot, melted plaster and metal, that only could have resulted from temperatures approaching 2,000 C. It also contained ruins of flattened buildings, including the town’s palace and four metre-thick outer wall.
“The city was built with millions of mud bricks, in the walls, the ramparts, the buildings,” space physicist Malcolm LeCompte, who was part of the research team, told Quirks & Quarks host Bob McDonald. “Much of the mud brick was just disintegrated and blown away off the upper stories of these structures into the next valley.”
Most gruesomely, the debris also contained the remains of humans and animals that had been burned and torn apart.
“The human remains and bones were abundant. There’s very few total skeletal remains. Those that do remain are pretty disarticulated — just shattered,” said LeCompte. “It’s pretty horrifying, actually.”
The extreme temperatures and the widespread and violent destruction began to point the research team to a culprit. But microscopic examination of the debris also helped build the case. They found sand grains with unique cracks and fractures within them called “shocked quartz,” which are often found in the debris from super-high velocity impacts, like those generated by a meteor strike.
This led them to conclude that the best fit for what they were seeing was an “air burst” by meteor likely composed of rock and ice. The object, perhaps 50 metres across, would have hit the Earth’s atmosphere above the town travelling at perhaps 60,000 km/h. At that speed the atmosphere would have behaved as if it was almost solid, causing the meteor to explode violently.
“The evidence we have suggests that it was something like … a megaton-yield event in terms of its equivalent in atomic or nuclear bombs.” said LeCompte.
On the ground, the flash of heat from the explosion would have caused hair and textiles to burst into flame, and melted metal and brick. Moments later, a shock wave would have hit, causing winds that researchers estimate reached speeds of up to 1,200 km/h — knocking structures in the town flat and killing every living thing in the town.
“The shock wave would have come and just torn them apart,” said LeCompte.
It will happen again, LeCompte warns
The researchers point out that there are modern precedents for an event like this. In 1908 a similar-sized object is thought to have exploded in the atmosphere over Siberia, in what is known as the Tunguska event. It flattened 2,000 square kilometres of forest, and started a huge forest fire.
In 2013 a roughly 200-metre meteor exploded over Chelyabinsk in Russia, shattering windows and causing more than 1,000 injuries.
So far the team has found some material they think could be from the meteor, including tiny samples of rare metals often found in meteorites, but need to do more work to confirm their origin. LeCompte points out that excavation in the area can be difficult, particularly as much of the local landscape is currently occupied by Syrian refugees.
One intriguing, if speculative, possibility that the researchers have suggested is that the destruction of Tall el-Hammam might be the inspiration behind Biblical legends like the destruction of Sodom — in what is described as a “rain” of “fire and brimstone” — or the destruction of the walls of Jericho.
But LeCompte says those that look at Tall el-Hammam as a historical curiosity are missing the point. Instead, he said, they should look at it as a warning.
“The significance to its past pales in what it foretells for the future, because this is going to happen again,” he said. The Tunguska event shows that the Earth can still be struck by destructive objects from space, and if something similar were to happen over a city or populated region, the devastation would be enormous.
“It just took it out in an instant, so that’s a serious warning of what could happen — what will happen — in the future.”

Archaeologists find oldest known human footprints in the Americas – HeritageDaily
Archaeologists conducting research in the White Sands National Park in New Mexico has identified the oldest known human footprints in the Americas.
The findings provide the earliest unequivocal evidence of human activity in the Americas from over 23,000 years ago, a period during the height of the last glacial cycle, known as the Last Glacial Maximum.
Archaeologists have debated for decades when the first people arrived in the Americas, but Vance T. Holliday from the UArizona School of Anthropology and Department of Geosciences said: “Few archaeologists see reliable evidence for sites older than about 16,000 years. Some think the arrival was later, no more than 13,000 years ago by makers of artefacts called Clovis points. The White Sands tracks provide a much earlier date. There are multiple layers of well-dated human tracks in streambeds where water flowed into an ancient lake. This was 10,000 years before Clovis people.”
The team used radiocarbon dating of seed layers above and below the footprints to determine their age, which showed human presence at the site lasting two millennia, and the oldest track dating back 23,000 years.
Kathleen Springer from the U.S. Geological Survey said: “Our dates on the seeds are tightly clustered and maintain stratigraphic order above and below multiple footprint horizons – this was a remarkable outcome”.
An analysis on the size of the human footprints suggests that they were mainly teenagers and younger children, whilst other tracks indicate that they were left by mammoths, giant ground sloths, dire wolves, and birds.
“It is an important site because all of the trackways we’ve found there show an interaction of humans in the landscape alongside extinct animals, like mammoths and giant sloths.” said Sally Reynolds of Bournemouth University. “We can see the co-existence between humans and animals on the site as a whole, and by being able to accurately date these footprints, we’re building a greater picture of the landscape.”

Bird reports rose during lockdowns | Cornell Chronicle – Cornell Chronicle
Around 80% of bird species examined in a new study were reported in greater numbers in human-altered habitats during pandemic lockdowns, according to new research based on data from the eBird program at the Cornell Lab of Ornithology.
In the paper, “Reduced Human Activity During COVID-19 Alters Avian Land Use Across North America,” published Sept. 22 in Science Advances, researchers compared online eBird observations from the United States and Canada from before and during the pandemic. They focused on areas within about 100 km of urban areas, major roads, and airports.
Vast amounts of data from a likewise vast geographic area were vital for this study. The researchers used more than 4 million eBird observations of 82 bird species from across Canada and the U.S.
“A lot of species we really care about became more abundant in human landscapes during the pandemic,” said study senior author Nicola Koper of the University of Manitoba, which led the research. “I was blown away by how many species were affected by decreased traffic and activity during lockdowns.”
Reports of bald eagles increased in cities with the strongest lockdowns. Ruby-throated hummingbirds were three times more likely to be reported within a kilometer of airports than before the pandemic. Barn swallows, a threatened species in Canada, were reported more often within a kilometer of roads than before the pandemic.
A few species decreased their use of human-altered habitat during the pandemic. Red-tailed hawk reports decreased near roads, perhaps because there was less roadkill when traffic declined. But far more species had increased counts in these human-dominated landscapes.
The authors filtered pandemic and pre-pandemic eBird reports so that the final data sets had the same characteristics, such as location, number of lists, and level of birdwatcher effort.
“We also needed to be aware of the detectability issue,” said co-author Alison Johnston, assistant director of the Center for Avian Population Studies and Ecological Data in the Lab of Ornithology. “Were species being reported in higher numbers because people could finally hear the birds without all the traffic noise, or was there a real ecological change in the numbers of birds present?”
The study tested whether better detectability might be a factor in the larger bird numbers reported. If it was, the scientists expected that to be more noticeable for smaller birds, which are harder to detect beneath traffic noise. However, effects were noticed across many species, from hawks to hummingbirds, suggesting that the increased numbers were not only caused by increased detectability in the quieter environments.
“Having so many people in North America and around the world paying attention to nature has been crucial to understanding how wildlife react to our presence,” says lead author Michael Schrimpf, a postdoctoral fellow at the University of Manitoba. “Studies such as this one rely on volunteer birdwatchers, so if you enjoy watching wildlife, there are many projects out there, like eBird and iNaturalist, that can use your help.”
The study was funded by Natural Sciences and Engineering Research Council of Canada with in-kind support provided by Environment and Climate Change Canada and the Cornell Lab of Ornithology.
