They come however in many different energies requiring different observing system to detect them. We at @oceannetworks.ca are helping the #P-ONE Collaboration build a large facility to detect the most energetic ones.

Ok. Peak-to-peak is more like 6cm now. Looks like double what I remember from Tohoku. #Tsunami @oceannetworks.ca

… and a better view of the first wave. Amplitude 2cm (but by 2,400m depth!). @oceannetworks.ca

Here we go. Here’s the first sign of the #Tsunami wave arriving near the Canada-US border offshore: this is the de-tided signal at the Endeavour site 300km offshore on the NEPTUNE observatory @oceannetworks.ca

This #Tsunami looks serious. Here’s what it looks like at Midway: Image courtesy of @noaa.gov

This is a VERY large earthquake, possibly/probably among the 10 largest ever recorded. A clear subduction zone megathrust event. And it is another M>8.5 event with a notable foreshock (the recent M7.4 in same location), like Tohoku in 2011.

Our @oceannetworks.ca Observatory Physical Operations staff Caleb and Peter are presenting the #P-ONE frame design at the P-ONE 2025 workshop hosted at @sfuscience.bsky.social

Just arrived at the 2025 #P-ONE workshop and was greeted with this pair of socks with our @oceannetworks.ca logo! Nice and welcoming!

Today, Planetary issued the first-ever verified Ocean Alkalinity Enhancement carbon removal credits, certified by Isometric and delivered to Stripe, Shopify, and British Airways. | Planetary Today, Planetary issued the first-ever verified Ocean Alkalinity Enhancement carbon removal credits, certified by Isometric and delivered to Stripe, Shopify, and British Airways. These credits demonstrate that our OAE is:  - Scientifically rigorous - Independently verifiable - Safely and actively deploying in the real world Our Tufts Cove project in Halifax dosed over 1,100 tonnes of alkalinity under regulatory oversight, with extensive monitoring and public engagement. The result: 625.6 tonnes of CO2 durably removed, now visible on the Isometric Registry. We are proud to help move OAE from promise to proof, and the work has just begun. Read the full announcement, along with the link to the registry, on our blog:  https://lnkd.in/e_EAZSrC >>> Ready to bring coastal CDR into your climate strategy? info@planetarytech.com <<< #CarbonRemoval #Climate #OAE #MRV #Planetary

Planetary delivered the world's first verified carbon removal tons from Ocean Alkalinity Enhancement (OAE)! www.linkedin.com/pos...

OAE helps undo ocean acidification to allow the it to naturally absorb more CO2 from the atmosphere.

(L to R) Kathy Sullivan, former NASA astronaut, US Navy officer, and NOAA Administrator; Honourable Marc Garneau, former Minister of Transport of Canada and Canadian astronaut, and Kate Moran, ONC CEO and President.

1/👩‍🚀ONC is celebrating the legacy of politician & #astronaut Honourable Marc Garneau, a friend to ONC & the ocean.

As Transport Minister, Honourable Garneau was not only dedicated to space exploration but also recognized the important role of ocean observing in protecting Canada’s ocean.

The primary energy fallacy is the idea that all primary energy from fossil fuels must be replaced with equivalent amount of clean energy.

BUT: Not necessary because conversion losses don’t need to be replaced. 2/3 of all primary energy is lost as waste heat. knowledge.energyinst.org/new-energy-w...

American Exceptionalism on full display.

“We can belittle you, threaten you, punish you. But how DARE you push back in the slightest way. That’s an insult.”

F this guy.

@katemoran.bsky.social - happening in BC!

Alternatively, since they’re positively charged, creating an electric field could focus them. But we’re adding weight and energy requirements: No longer at the mg scale and probably not energy positive! Fun though!

Got it. Thanks. Too bad we can only absorb them and not bounce them back off … something… for added momentum.

The next obvious question to me (unless I missed some important aspect of the aerogel) is beaming the particles. I would assume that their dissipation is isotropic. So what material would reflect (as opposed to absorb) the particles and beam them in the right direction so as to create a useful dV?

Are you trying to design a µ-spacecraft propulsion system?? :)

In this diagram showing battery production capacity by country, Canada is currently only #20 by energy capacity, but has projected production by 2027 that should bring it closer to the top. Let’s hope that materializes.

"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?" "Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."

I think a lot about what Carl Sagan said in one of his final interviews.

Counter tariff impacts are already reflected in the price of Tesla’s in Canada. We are seeing price increases of 15-20% for new vehicles (before taxes, which will apply on top of the tariffs)! They’re going to have a hard time selling any here now.

I now use FSD every day. Seriously improved over the past ~4 months. If I occasionally disengage it’s often because I reacted too quickly to something it would have dealt with. Main peeves have to do with the use of direction indicators (on too soon), and the long stop (≥1 sec) at every stop sign!

Noticed that too. It’s when the cross-traffic lights turn red. You can hear the break release at that moment. I do that myself when I drive. I was impressed when I noticed it happening repeatedly at different locations. Pretty cool.

So many companies have US ownership these days… We still want to eat more than carrots and kale from the farmer’s market. So we just look at provenance. CDN provenance will hopefully mean local jobs for all or part of production, processing and delivery.

We have more systematic targeted retaliations, too: alcohol from red states have been pulled from the shelves in liquor stores and restaurants have mostly replaced their US wines from the menu with local, European or anz and latam products. We’re targeting the source, not the reseller.

In Canada, it’s mostly directly at the grocery store that most people are now checking the country of origin. So e.g,, a red bell pepper from Canada is good, an avocado from Mexico is good, but lettuce from the US stays on the shelf, even if cheaper.
