- 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? #nature #outdoors #explore #winter #wild #wilderness #discover
- To my LGBTQ+ following on here (especially the non-binary and trans community), know that you will ALWAYS be welcome within this space. It's saddening that we have to explicitly state that, but know that anyone trying to "erase" or deny your existence and basic human rights is NOT welcome here.
- I've entered 2025 with an unparalleled level of ruthlessness for email deletion... it's very cleansing. (But I apologise in advance if anyone gets accidentally caught up in the firestorm 🙃)
- 🧊 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.
- Next up in the "penguins on cool icebergs with murky skies" series... #Antarctic #Antarctica #wildlife #wildlifephotography #penguin #penguins #ice #iceberg #ocean
- 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... 👌🏼👌🏼🐧🇦🇶🧊 #Antarctica #Antarctic #photography #wildlifephotography
- 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
- This is Spigot Peak at Orne Harbor on the Western Antractic Peninsula. A volcanic peak riddled with intruded dykes.
- We're advertising a series of 14 projects for Masters by Research (MScR Geology) at @bristolvolcanology.bsky.social @bristoluni.bsky.social . Either 1 yr full time or 2 years part-time. Find more details here (including our PhD projects available): www.bristol.ac.uk/earthscience...
- Please share with any keen undergraduates looking for volcanology research experience. We recommend any prospective students reach out to potential project supervisors in the new year.
- Check out the #AGUVGP summary for today! It's a busy one, including the Reginald Daly Lecture at 10:20 given by Christy Till @ctill.bsky.social
- ⭐ Happy Day 1 of #AGU24 ⭐ Today is packed with exciting 🌋 talks and posters! We'll be advertising the #AGUVGP day-by-day schedule here and on our other social channels. We have three oral presentation sessions this morning, starting with: agu.confex.com/agu/agu24/me...
- 🌋🧪 #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: www.usgs.gov/programs/VHP...
