Folks at #IAVCEI2025! Fancy a quick interview for media at lunchtime today?
Literally just some quick snappy answers (what's you favourite volcano, what volcano would you love to visit etc.)

I'll up the stairs above the middle of the poster hall from 13:30-14:15. @iavcei.bsky.social

The #IAVCEI2025 swag game is strong! Especially the fan im the 35°C heat! Already socially overloaded, but so good to see so many people! @iavcei.bsky.social

Arrival in, a very warm but lovely, Geneva for the International volcanology conference! #IAVCEI2025 begins here! @iavcei.bsky.social #IAVCEI

A BIG shoutout to @geologytalk.bsky.social who illustrated the final figure in our most recent paper!
A final schematic of your ideas can be crucial to the understanding of a paper, so having someone with such a creative eye really elevates the final article! www.sciencedirect.com/science/arti...

When your workload is at full capacity but... cool new science?... #academia

A LONG time coming, but I'm finally, and properly, moving into the world of YouTube to force myself into making some longer content. www.youtube.com/@smitchell_s...

For now, expect the usual snappy shorts, but longer stuff IS in the works! Any subscribers to get it started are appreciated! 😁

Ever wondered what bubbles trapped in a frozen lake look like down the 🔬??? 🫧 🧊 I took the @beaverlab.tech Darwin M2(S) handheld microscope out into the field with me to explore the micro-world!

More about this microscope soon and what we saw down the lens! Message me if this might interest you!

Take the time to reconnect with nature when (and if) you can 🏞🏕 There's an assumption that those who work in nature spend a lot of time outdoors... not always the case.

How do you make sure you connect with nature on a regular basis?

🧊 Shades of blue 🧊 Another year, another contract finished expedition guiding down in #Antarctica. Learning more every time, working alongside an incredibly dedicated team, and learning more about myself as an science communicator. Feeling refreshed to launch into 2025's research projects.

First Antarctic photo with the new 📷 lens...
I love photos with layers, contrast, and depth. A murky grey sky really makes the blue of ice pop. Add in the snow falling and the two chinstrap penguins looking the same way... 👌🏼👌🏼🐧🇦🇶🧊

There are worse views at 7am... the Christmas clouds and snow are clearing a little down here. Volcanic rocks, a penguin colony, and still water make for a good morning of boat driving 🙏🏼🩵 #Antractica #Antarctic #photography #naturephotography #landscape #mountains #water #ice #geology #nature

🌋🧪 #ScienceAdventCalendar Day 6 (yes, I've already fallen behind...)

Volcanoes produce a LOT of gas, but still only ~1% of the CO2 amount produced by human activity. Even the biggest modern eruptions come nowhere near close!

Handy article about volcanoes and climate:

🌋🧪 #ScienceAdventCalendar Day 5!

Let's talk about the OTHER polar #volcano - Mt Erebus in #Antarctica. This 🌋 is one of only a few worldwide with an active lava lake in its crater! Technically NOT on Antarctica (Ross Island), this is the southernmost active volcano in the world

On this account I said I will post about science... but also penguins.

So, enjoy... here is my best [favourite] #penguin photo. (It's not winning any photography awards, but it gives me life). 🐧🤍

🌋 🧪 #ScienceAdventCalendar Day 4!

Did you know that Norway has its own active 🌋? Beerenberg volcano, on Jan Mayen island in the Arctic Ocean, last erupted in the 1980s. There is no permanent population on the island and is the world's most northern active volcano on land!

🌋 #ScienceAdventCalendar Day 3!

The big picture: There are thought to be ~1300 "active" volcanoes around the world. This accounts for any volcano with a likely eruption over the Holocene - the last 12,000 years.

While I like the premise of personally-tailored recommendations for #AGU24 , I just got recommended to meet myself and attend my own talk. 😅 That will only end up in an argument... I'm very self-confrontational... 🫠

SCIENCE ADVENT CALENDAR Day 2:

The tallest point on Earth is a 🌋- Mt Chimborazo in Ecuador (NOT Mt Everest or Mauna Kea). Reason: The Earth bulges at the Equator (where Chimborazo is), so it is "technically" the furthest point from Earth's center.

Happy Antarctica Day ! Just a few of my favourite 📸 from the past couple of years. Still water always makes for the best iceberg moments!

Who wants to join in with a #ScienceAdventCalendar over December, with facts each day about their field?

Here's #1: Zavodovski in the South Sandwich Islands (near Antarctica) is an active volcanic island and home to the largest penguin colony in the world! >1 million!

Time to begin this whole BlueSky thing!Time to build/rebuild a new sci-comm network!

Come along for things about volcanoes, ocean science, geology, and maybe the odd penguin! #science
