2025 β€” Mineral Cup

We have a #MinCup25 champion!!

Congratulations, #Kyanite!

After eight years of competing, another few hours to verify votes was nothing, right?

Amazing first run, #Tugtupite, and better luck next year.

To The Best Of Our Knowledge Intelligent. Optimistic. Curious.

I was heartbroken to hear of the end of TTBOOK.

I have been listening to "To The Best Of Our Knowledge" for what feels like my whole life. I don't think its possible to express the impact it has had on my life.

It has 35 years of compelling ideas and interviews in their archive

I don't remember when I saw that they were going to make it, but I sent it to my friend who is in a lego club with his kids so he would remind me. It came out yesterday!

Advances in Seismoacoustics I Oral This session explores advances in research on seismoacoustic signalsβ€”acoustic and seismic waves generated by natural phenomena (e.g., earthquakes, volcanoes, severe weather) and anthropogenic sources ...

#AGU25 session schedule is out! Looks like December 18 is Infrasound day!

Oral I: agu.confex.com/agu/agu25/me...

I am always happy to chat away about #infrasound! You never know when someone might bring up a colleague who you didn't know about who worked in the field back in the day when things were less... open...

Every year at Tucson Gem show, I gaze lovingly at the tables of the perfect shade of green. Every year, I find a little Dioptase cave that I want to curl up in like a tiny dragon.

Also, I once saw a tiny gem cut Dioptase for $80. I cry over not purchasing it.

#MinCup25
Vote Dioptase!

We all learn differently and I decided I needed more hands on experience after my Masters so I took research jobs to get it! Every path is unique and valid! We aren't cookie cutters and thats important!

Here's the @auscope.bsky.social Seismometers in Schools recording this morning's M7.8 Kamchatka earthquake. Data and network visualisation is from SRC's Seismosphere.
The 24-hour single station view from Nhulunbuy in the Northern Territory shows the seismometer detecting the earth ringing for hours!

The reason I started saying this is b/c many of my students haven’t had opportunities to actually think for themselves or collaboratively come to consensus to shape an idea. I blame this on k-12 standardized tests/worksheets and poor/uneven implementation of NGSS (what science ed *should* be).

Modern spectrograms are awesome but there is just something so cool about older ones like this.... Liu (1985) the signal from the May 18, 1980 eruption of Mt St Helens in China!

The best way to start the day is with an email from someone saying they are using your research. πŸ₯°

Everyone writing about Perseverance today should be asking how many of the scientists and engineers who were involved in this discovery no longer work for NASA bc of Trump.

If anyone on #TeamInfrasound ever needs student projects... I have a list...

Pro tip: keep a document of ideas for projects and papers.

BUT split them into things YOU want to do vs. something SOMEONE should do (you would be ok not being involved).

You can also have a list of things that would be a good student project. Then when you have an idea it has a home.

Seriously excited about the lineup we have for #TeamInfrasound at #AGU this year. Its going to be a different mix (obviously) but still a very strong set of talks. Just in case you need a little bright spot today!

Snap, crackle and pop!

Love the booming explosions from the summit vent in the background.

Hello fellow scientists!
I am a geophysicist specializing in #infrasound, early warning systems, and helping people understand the active geology where they live.

I am also a huge early music lover (and entered Uni as a performance major)!

Currently in NZ but making a big move to Europe soon!

Made a figure.
Questioned the figure.
Spent all day recalculating and replotting.
Original figure was correct.
