One billion seashore animal deaths an 'underestimate,' researcher says – Powell River Peak

Published

 on


As temperatures on land hit record highs three days in a row late last month on the Sunshine Coast, researchers and residents alike noticed a putrid smell emanating from the shoreline. Thousands of shells were cracked open, tissues exposed – seashore life had been cooked alive by the heat wave.

“It smelled like death,” said Fiona Beaty, a PhD candidate at the University of British Columbia.

“Now if you walk along the beaches, there’s all of these empty mussel shells that have washed up, so the beaches are crunchy,” she said.

Beaty, who lives in Gibsons, is part of UBC professor and marine biologist Chris Harley’s lab studying marine life and how climate change affects organisms in the intertidal zone.

Soon after the heat wave, headlines reported Harley’s estimate that more than a billion seashore animals had likely died in the Salish Sea due to the extreme conditions.

When he first saw the forecast for the end of June, Harley said he expected some die off, but when he walked to his local beach on June 27, he could smell the rot before he saw it.

“Now that I’ve seen more shorelines, I’m convinced that that number is a substantial underestimate. It’s going to be way more than a billion animals have died,” Harley told Coast Reporter on July 13.

One of the flagship species to die was the mussels, which act as both food and habitat for other species. That temporary loss could take years to recover, Harley said, and is not limited to mussels.

The team is also studying the impact on barnacles, oysters, snails, clams, crabs and seaweed.

Questions remain as to the impact on species such as the migratory surf scoters, ducks that rely on mussels in the Howe Sound region for food before breeding in the Arctic. If those birds cannot eat enough mussels, Harley said researchers anticipate a potential impact on herring spawn.

“It’s possible that we’re going to have ripples out from the species that have died into all sorts of unexpected corners of the ecosystem,” he said.

Water quality

The curator at the Nicholas Sonntag Marine Education Centre, Jenny Wright, said there could also be a negative impact on coastal water quality.

“The mussels would usually filter the majority of bacteria and harmful algae out of these waters, therefore without them we may see an increase in harmful algal blooms along the coast,” Wright said in an email.

Part of the high mortality rate was caused by a low tide series that coincided with the heat wave. Beaty said the creatures were exposed to the high temperatures for much longer than they otherwise would have been.

Prior to the heat wave, Harley’s research team had already set up a study zone in the Selma Park area, where they had observed a different pattern of life in the intertidal zone. Normally different species will form layers on rocky shores, but in Selma Park, the pattern usually observed was turned sideways from north to south. Beaty said across the Sunshine Coast, the mussels that were growing on the south side of boulders, where they receive more sun, have largely died. On the north side, with more shade, those lifeforms were more protected and some survived.

“That decision a mussel made when it was a larva choosing where to attach had huge consequences on those hot days,” Harley said.

Secret Beach

When Michael Maser went snorkeling on July 10, the impact of the heat wave was obvious. At Secret Beach in Gibsons, he saw dead mussels and sea stars visible in the intertidal zone.

“I snorkel there frequently and I can assure you it otherwise supports a very healthy population of marine life,” Maser said in an email to Coast Reporter. “Not all the mussels are dead, many survived, but there are patches – like mange on a dog – where all the mussels have died.”

Five years ago, the Pender Harbour Ocean Discovery Station (PODS) began monitoring programs for the area’s 40 to 50 species in the intertidal zone. Michael Jackson, the executive director of the Loon Foundation that oversees PODS, said they knew an event like this was coming, and pre-emptively gathered data to track the changes, causes and effects.

Even though the intertidal zone is probably one of the most inhospitable places to live, he said the heat wave was “without a doubt devastating.” In the Pender Harbour area, Jackson said they’ve seen mussels and young crabs rotting away, and he worries the stagnating flesh is affecting the fish. He agrees with Harley that the mortality rate is much higher than the initial estimate of a billion.

Climate change

“This is such a clear example of how climate change is affecting our beaches right now,” Beaty said. “In our lab, we’re studying this with the expectation that it’s going to be like 10, 20, 50 years down the road. But when this happens, now we’re talking about what are the beaches going to look like next year? Are these animals going to be able to regrow? Or will we get another heat wave at this time of year that’s just going to knock things back again? It hits home on that deeper level.”

She also noted that the Salish Sea is heating up at twice the average rate of warming, because it is an inland body of water.

“This area might be a hotspot for the negative effects of climate change,” Beaty said, adding she hopes it will act as a red flag to raise awareness and engagement of people living on the Coast.

On the Sunshine Coast, Harley and his lab researchers are continuing to catalogue the extent of the damage from the heat wave in Halfmoon Bay and at Selma Park. Beaty has checked beaches in Gibsons and Roberts Creek on her own time. The team was also invited by a Garden Bay resident to examine the impact at her beach access, which Beaty says shows how much the loss has resonated with coastal residents.

“This is a tragedy, but the thing that I find inspiring about it is that people care and have been sending in their observations, and it gives me some hope that people still love nature,” Harley said.

“And if we love nature, we will continue to do things to try to protect it, which would include helping to mitigate the effects of climate change and future heat waves.”

The researchers are collaborating with others on B.C.’s coast and in Washington, and will submit a summary paper to a peer-reviewed journal later this year. In the meantime, Harley said residents interested in submitting their observations can contact him at harley@zoology.ubc.ca.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
